Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated or Inferred Resources: The United States Securities and Exchange Commission (“SEC”) permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. The Company uses certain terms in this Annual Information Form, such as “measured,” “indicated,” and “inferred” “resources,” which the SEC guidelines prohibit U.S. registered companies from including in their filings with the SEC. U.S. Investors are urged to consider closely the disclosure in the Company’s Form 40-F which may be secured from Canadian Zinc, or from the SEC’s website at http://www.sec.gov/edgar.shtml. “Inferred mineral resources” have significant uncertainty as to their existence, and as to their economic feasibility. United States investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically mineable. It cannot be assumed that all or any part of an inferred mineral resource would ever be upgraded to a higher category. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves.

Cautionary Note: Mineral Resources that are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that all or any part of an inferred mineral resource will ever be upgraded to a measured or indicated mineral resource or to a mineral reserve.

GENERAL DEVELOPMENT OF THE BUSINESS

Canadian Zinc is a public company listed on the Toronto Stock Exchange under the symbol “CZN” and traded on the OTCQB under the symbol “CZICF” and is engaged in the business of exploration and, when warranted, development of natural resource properties. The Company’s principal focus is the development of the Prairie Creek property (the “Prairie Creek Property”, “Prairie Creek Project” or “Prairie Creek Mine”) in the Northwest Territories, Canada and the exploration of the South Tally Pond property in Newfoundland and Labrador, Canada.

The Prairie Creek Property contains a zinc/lead/silver mineral resource with adjacent mill and mine infrastructure facilities, located approximately 500 kilometres west of Yellowknife in the Northwest Territories, Canada. South Tally Pond, in the Canadian province of Newfoundland and Labrador, is a zinc/lead/copper/gold/silver mineral resource with a potential opportunity to develop into a viable economic resource and located immediately adjacent to Teck Resources Limited’s operating Duck Pond mine and mill complex.

Three Year History

Throughout the years 2010, 2011 and 2012, the Company’s principal focus has been its efforts to advance the Prairie Creek Project towards completion of development and subsequent production, principally in the re-permitting and environmental assessment process.

Permitting Related

Operating Permit Applications

Environmental Assessment

In 2008, the Company applied to the Mackenzie Valley Land and Water Board (“Water Board” or “MVLWB”) for a Water Licence and associated land use permits (“LUP” or “Land Use Permits”) to support a mining operation at Prairie Creek. The application was referred to an Environmental Assessment (the “EA” or “Environmental Assessment”) under the Mackenzie Valley Environmental Impact Review Board (the “Review Board”), the primary authority responsible for all environmental assessment and review throughout the Mackenzie Valley in the Northwest Territories, and has since worked through the various stages within the EA. These stages included a written hearing, submittal of a Developers Assessment Report, two formal Information Requests and two Technical Sessions, a Community Hearing, a two-day Public Hearing, and Final Submissions.

On December 8, 2011, the Review Board issued its Report of Environmental Assessment and Reasons for Decision (the “EA Report”) for the Company’s proposed Prairie Creek Mine and submitted the EA Report to the Federal Minister of Aboriginal Affairs and Northern Development. The Review Board concluded that the proposed development of the Prairie Creek Mine is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern. The Review Board concluded that an environmental impact review of this proposed development is not necessary and that the proposed Prairie Creek Mine project should proceed to the regulatory phase for approvals by the Water Board.

In a decision dated June 8, 2012, the Minister of Aboriginal Affairs and Northern Development, on behalf of the responsible Ministers with jurisdiction, including the Minister of the Environment, the Minister of Fisheries and Oceans, the Minister of Environment and Natural Resources, the Minister of Transport Canada and the Minister of Environment and Natural Resources of Government of the Northwest Territories, advised the Review Board of the decision that the Ministers will not order an environmental impact review of the proposed development of the Prairie Creek Mine, nor will they refer the proposal to the Minister of the Environment for a Canadian Environmental Assessment Act joint panel review.

In January 2012, following the completion of the Environmental Assessment in December 2011, the Water Board commenced the regulatory process for the issue of a Class “A” Water Licence and Land Use Permits for the operation of the Prairie Creek Mine. In February 2012, the Company submitted a Consolidated Project Description (“CPD”), highlighting the changes that resulted from commitments made by Canadian Zinc during the environmental assessment process.

Since the original applications for operating permits were submitted to the Water Board in 2008, the adjacent Nahanni National Park Reserve (“NNPR”) was expanded in 2009 and now encircles the Prairie Creek Property; however the Prairie Creek Property was excluded from the expansion area and is not part of the Park. The park expansion area now includes a significant portion of the Prairie Creek Access Road route, however, when NNPR was expanded the Canada National Parks Act was amended to enable the Minister of the Environment to enter into leases or licences of occupation of, and easements over, public lands situated in the expansion area for the purposes of a mining access road leading the Prairie Creek area, including the sites of storage and other facilities connected with that road. The applications for land use permits, and water licences relating to the road access are now multi-jurisdictional and the Company has applied to both to the Water Board and Parks Canada for road related permits and licences.

The Water Board completed its review of the information contained in the application, Environmental Assessment and the CPD and in May 2012, issued a Directive on additional information required by the Water Board at this stage of the Regulatory Process.

During the course of the previous Environmental Assessment the Company committed to further water quality/treatment studies. The water quality/treatment studies are based on products generated from representative bulk rock and water samples previously collected from site which have been processed utilizing a milling process circuit developed from previous metallurgical studies by SGS Lakefield.

In the fall of 2011, the Company collected a 700 kg bulk composite sample of mineralization from the 870m and 930m underground levels at Prairie Creek. The material was shipped to SGS Minerals Services in Vancouver for processing. The locked cycle tests were performed with water that was collected and shipped down from the Prairie Creek Mine in order to produce representative process water. The sample was crushed and sorted then sent to SGS Lakefield to undergo Dense Media Separation and then returned to Vancouver.

SGS has carried out a number of locked cycle tests in order to generate mineral concentrates, waste tailings and waste water. The process water then underwent further treatment studies conducted by CEMI Labs along with toxicity studies by Hatfield Consultants. Other generated products, such as the tailings, are slated for further engineering studies related to paste backfill.

In October 2012, the Company filed its response to the Water Board and in a further submission in November incorporated the results of additional water quality/treatment studies received from SGS Lakefield and CEMI Labs. Due to the necessary time required to complete the lab testing program the Water Board revised the original work plan.

In November 2012, a series of technical sessions were held in Yellowknife to review the Company’s submissions to the Water Board. The sessions resulted in triggering 24 additional Information Requests which the Company responded to in December 2012. Follow-up meetings to further discuss the Information Requests were held in Yellowknife and Fort Simpson during the week of December 20, 2012.

Formal written interventions to the MVLWB were submitted by the Intervening Parties on January 11, 2013 and CZN submitted a response to the Interventions on January 18, 2013. Beginning on January 29, 2013, the Company and Intervenors attended Public Hearings held in Fort Simpson. The three day session was adjudicated by the Water Board. A Public Hearing scheduled to be held in Nahanni Butte February 1, 2013 was postponed due to weather and held as a teleconference on February 8, 2013. Final closing statements by all Intervenors were filed by February 15, 2013 and the Company filed its’ closing statement February 22, 2013.

On March 15, 2013 the Water Board issued a Draft Type “A” Water Licence and two Draft Type “A” Land Use Permits for the operation of the Prairie Creek Mine.

The Water Licence will entitle Canadian Zinc to conduct mining, milling and associated activities at the Prairie Creek Mine Site, dewater the underground mine for the purpose of mining, use water for processing and domestic purposes, and to dispose of waste for mining and milling, and backfill paste tailings and waste rock into the underground mine. The Land Use Permits will authorize construction and other activities on the Prairie Creek Mine site and on the winter road Transfer Facility near the Liard highway.

The Water Board circulated the draft Water Licence and draft Land Use Permits to the government agencies and departments and to interested parties and requested comments by April 12, 2013. Canadian Zinc will have a further period of one week to review any comments and to respond to the Water Board with its own comments. All comments received will be used in the evaluation of the final licence and permit conditions. The revised draft Licence and draft Land Use Permits will then be submitted to a meeting of the Water Board for formal approval. Following approval by the Water Board, the Water Licence will be sent to the federal Minister of Aboriginal Affairs and Northern Development for ratification.

Documentation related to this regulatory process is posted on the Water Board website at www.mvlwb.ca/mv/registry.aspx (Year 2008, Canadian Zinc MV2008L2-0002).

Road Land Use Permits (Operations)

In January 2013, the Water Board issued the Company a Land Use Permit MV2012F007 allowing the establishment and operation of the winter road that will service an operating Prairie Creek Mine. The Land Use Permit was issued for a period of five years ending in January 2018, and permits the construction, maintenance, operation and use of a portion of the winter road connecting the Prairie Creek Mine to the Liard Highway, situated outside the expanded Nahanni National Park Reserve. This permit allows the outbound transportation of the zinc and lead concentrates to be produced at the mine and the inbound transportation of fuel and other supplies during the actual operation of the Prairie Creek Mine. The road permit also incorporates realignment of the original route which will improve access and further reduce potential environmental impact. Associated with this LUP the MVLWB also issued a Type “B” Water Licence MV2012L1-0005, valid for a period of seven years, to allow the limited use of local water resources and disposal of waste during road construction and operations.

An additional Land Use Permit and Water Licence for operations relating to the portion of the access road that runs through the Nahanni National Park Reserve are required. A partial road application was submitted to Parks Canada in June 2012. Further field information was collected in September 2012 and the required documentation was submitted on November 19, 2012. Subsequent information was forwarded to Parks Canada on February 13, 2013.

In July 2012, Parks Canada extended the LUP for that portion of the road that passes through the expanded Nahanni National Park Reserve for an additional term of two years to April 2014. These permits will allow CZN to undertake road rehabilitation work and prepare the road for operational use. The permits allow use of the road for the re-supply and maintenance of the mine, but do not provide for the planned operational use of the road.

In July 2012, Transport Canada confirmed that the proposed road works, including proposed new bridges, are not subject to the Navigable Waters Protection Act and therefore the Navigable Water Protection Act is not applicable to the proposed works.

Exploration Permit Applications

New Mine Decline Land Use Permit Issued (Exploration)

In May 2012, the Water Board issued a new Class “A” Land Use Permit, MV2012C0008, for the activity of underground decline development, valid for a period of five years commencing May 10, 2012 and expiring on May 9, 2017. The new Land Use Permit entitles CZN to conduct mining exploration and associated activities, including underground decline development, at the Prairie Creek Mine.

The new decline and underground development will be strategically located to facilitate the drilling of key areas and also to allow integration of the underground development with that required to further access the mine resource, and to enable drilling of the under-explored portions of the deposit at depth during the period leading up to mine construction.

Class “B” Water Licence Amended and Extended (Exploration)

The Water Board also approved an amendment and extension to the Company’s existing Class “B” Water Licence, MV2001L2-0003, for the management, treatment and discharge of mine water from the mine site. The Water Licence has now been amended to cover the underground development of the new decline from the existing 870m level, including pumping, treatment and discharge of water inflows using the existing water treatment infrastructure, and placement of waste rock on an existing waste rock pile. The term of the Water Licence has been extended to September 9, 2019.

With the issue of an amended Water Licence, a new Minewater Contingency Plan was submitted for review. An application to revise the compliance levels to be comparable to the Metal Mining Liquid Effluent Regulations was made in August and approved by the Water Board on January 23, 2013 for a period of one year after which it will revert back to the original licence compliance levels.

Prairie Creek Development

Preliminary Feasibility Study

A Preliminary Feasibility Study (“PFS” or “Preliminary Feasibility Study”) prepared by SNC-Lavalin Inc. (“SNC” or “SNC-Lavalin”) of Vancouver was submitted to the Company in June 2012 and the corresponding Technical Report by AMC Mining Consultants (Canada) Ltd. (the “AMC Technical Report”) entitled “Prairie Creek Property, Northwest Territories, Canada, Technical Report for Canadian Zinc Corporation” Qualified Persons J. M. Shannon, P. Geo., AMC Mining Consultants Ltd.; D. Nussipakynova, P. Geo., AMC Mining Consultants Ltd.; JB Hancock, P. Eng., Barrie Hancock & Associates Inc.; and B MacLean, P.

Site Programs

An auger drill rig contracted from Mobile Augers and Research Ltd. in Edmonton was airlifted to the Prairie Creek site. The auger drill completed a series of geotechnical holes within the existing water storage pond and also in areas proposed for the waste rock pile and a possible second water storage pond. This provided further engineering information for design and construction purposes and also for permitting requirements. Drilling a series of hydrological groundwater wells was also completed to further monitor the hydrology of the site area in preparation for mining activities.

Field work including geotechnical evaluation and studies of the road route through Nahanni National Park Reserve and adjacent areas has also been carried out. This included assessment of specific areas of route re-alignment focusing on bridge crossings, reducing steep grades and substratum assessment. A hydrologic assessment was also completed along the road corridor to support further regulatory requirements.

A detailed aerial light detection and ranging system (“LIDAR”) survey in combination with new surface imagery was also carried out by McElhanney Surveying utilizing a fixed wing aircraft. This survey provided accurate baseline data and maps for road routing and re-alignment and also for construction planning along the road and at the mine site.

Further assessment work of the Prairie Creek Mine site was completed by various contractors. These included material inspections, roof and building envelope assessments and site refurbishment studies. Additional assessment of the mill and camp facilities were carried out with engineers from SNC-Lavalin visiting and assessing the existing facilities. Underhill Geomatics Inc. completed a comprehensive internal laser scan survey within the mill building to provide “as built” engineering data for further design and planning.

Site Assessment

A number of additional studies were completed with regards to addressing the various environmental aspects of the proposed Prairie Creek Operation. Most of these studies revolved around site water management and water quality.

It was determined, during the regulatory process technical sessions that it was necessary to accurately measure the flow of Prairie Creek on a real-time basis if a load-based approach to water discharge could be considered.

Therefore a study was initiated and completed by EBA, a Tetratech Company, on developing a real-time flow measurement protocol that could be applied to accurately measuring the flow volume in the Prairie Creek stream on a real-time basis throughout the entire year. In tandem with this study, discussions were also held with the Water Survey of Canada regarding their support for re-establishing a flow monitoring station on Prairie Creek. As a result of further design changes in the exfiltration trench, Hatfield Consultants completed an amendment to the Fish Habitat Assessment in the proximity of the trench. Further discussions, during the regulatory process, relating to water quality led to a need to complete additional Environmental Risk Assessment toxicity studies for particular analytes and these were calculated by Hatfield Consultants. At the Prairie Creek Mine site, SNC completed further water treatment plant design and engineering as the regulatory process required specific information on water treatment and on site lab analysis. Further engineering design was required to be completed by Golder and Associates relating to the newly designed Water Storage Pond where a lift of the berms was proposed to further enhance its’ capacity. Golder and Associates also completed preliminary designs for a possible second water storage pond. Geotechnical drilling was completed earlier in the year at both sites.

Further engineering related to the access road included route planning, crossing structure design, substrate evaluations, geotechnical studies, storage facility designs, construction scheduling and preliminary costing. Most of the road work was completed based on recently issued orthophotos based on the McElhanney Surveying LIDAR imagery survey completed in June 2012. A second geotechnical helicopter supported field program involving drilling, surveying and sampling to further detail the route was completed in late September. This drill testing included standard penetrating load tests and permafrost testing in areas where new structures or significant road cutting are proposed. A communication study along the access road was also completed in order to determine if additional land based repeater towers maybe required along the road. An Archaeological Impact Assessment study of the new road route along the front range of the Nahanni was completed by Golder & Associates which found there to be no new archeological sites.

Additional engineering site studies included many detailed aspects of the site including, in particular, internal mill design which utilized accurate survey data collected earlier from the internal laser scan completed within the mill complex by Underhill Geomatics. Structural/architectural studies were completed regarding installation of new flotation circuits and incorporation of Dense Media Separation plant and Paste Backfill plant into the existing mill building. Further details of piping, mechanical equipment, conveyor systems, pumps, heating and ventilation system, instrumentation and controls were also completed or in progress.

A new diesel generating system is planned for the site and associated electrical load calculations, electrical equipment assessment were completed along with associated heat recovery calculations from the generators. It is proposed that the new generators be brought onto site on a turn-key basis and be self-contained. The original powerhouse in the mill complex would be converted into a water treatment plant. Further site facility design including accommodations, workshops, waste rock pile, storage buildings, and tank farm design was completed. Value added engineering studies were carried out to identify areas of possible optimization. Some preliminary procurement planning was completed in order to further confirm possible costs of some longer lead-time items. A preliminary site construction schedule was developed and an early works program was proposed.

Exploration Programs

In 2010, the Company conducted a diamond drill exploration program. The program was designed to test for extensions for the inferred vein mineral resource in the Caskett Creek Area to the north of the Prairie Creek Mine, where the host geology and structure are projected to continue at depth, approximately 1.5 kilometres north of the last drill hole within the currently defined mineral resource. A total of 2,703 metres of drilling was completed in three holes.

In 2011, the Company continued the deep drilling program started in 2010 by extending drillhole PC-10-187 to test for extensions of the Mineral Resource at the Prairie Creek Mine, 1.5 kilometres to the south. The deep drilling program in the Casket Creek area totaled 2,513 metres of coring in four holes including wedges and successfully intersected significant vein-type zinc and lead mineralization about 1.6 kilometres north along a projected strike extension of the geological structure that hosts the defined mineral resource at the mine and demonstrated the probable continuation of vein-type mineralization similar to that located within the main zone at the Prairie Creek Mine.

The Company also undertook a 2011 summer diamond drill program adjacent to the Prairie Creek Mine to test for additional high-grade vein structures and for other, wider stratabound deposits adjacent to the resource.

In summary, 26 shallow holes were drilled with the Company’s Longyear rig, achieving 3,125 metres of coring directed at vein and stratabound targets in the immediate mine area. The vein structure was intersected and identified in each completed hole, many of which returned high grade base metal values.

In 2012, the Company contracted Cabo Drilling (Pacific) Corp. to supply manpower and technical supervision for a summer diamond drill program during which a total of 5,629 metres of drilling was completed utilizing Company owned drills.

Drilling at Casket Creek continued in 2012 commencing in May and ending in August. A total of 2,182 metres over two drillholes (with wedging) was completed. The drill core confirmed stratigraphy and contained a number of significant structural zones that are weakly mineralized and likely correlate with the previous years’ intercept. A third hole, PC-12-213, was halted due to drilling difficulties within a significant fault structure, believed to be the main structural target.

Infill drilling focused close to the minesite and within the defined resource was carried out with the Company’s Longyear #1 drill rig. Drilling commenced in June 2012 and was completed in September. Most of these holes were drilled at depth and along strike in the proximity of the known underground workings. Targeted areas included locations that have the potential to be upgraded from the inferred category to the indicated resource category. A total of 3,366 metres over nine holes were drilled, with seven holes completed to target in 2012, six of which intersected significant mineralization and many with multiple intercepts

Drillhole PC-12-216 returned the highest grades of silver ever reported from a drillhole on the Prairie Creek property with an intercept of 1.3 metres grading 2059 g/t or 60 oz./ton Ag. The same hole also returned a combined grade of 51.3% lead and zinc over a different intercept of 1.0 metre. Many other intercepts returned multi-ounce silver assays with high lead and zinc values, with Hole PC-12-214 reporting double intercepts of 44% and 23% combined lead and zinc, and Hole PC-12-215 also reporting double intercepts of 43% and 16.2% combined lead and zinc. Results are now being incorporated into the mine model and assessed for future exploration planning.

A surface geophysical program involving both electromagnetic (EM) and gravity surveys was also completed on a small part of the Prairie Creek property in the proximity of the mine in August 2012. Interpreted results indicate a strong multi-channel EM anomaly, with a coincident gravity anomaly, centered over a previously undrilled area immediately west of the existing underground workings. Further analysis of this anomaly is underway.

The Company has continuously undertaken discussion and engagement with local communities and government at all levels to establish mutually beneficial, cooperative and productive relationships.

In January 2011, the Company signed the Nah?a Dene Prairie Creek Agreement, which provides for an ongoing working relationship between Canadian Zinc and the Nah?a Dehe Dene Band (“Nahanni Butte Dene Band”) that respects the goals and aspirations of each party and will enable the Nahanni community members to participate in the opportunities and benefits offered by the Prairie Creek Project and confirms their support for the Prairie Creek Mine. (See also “Description of the Business – Nahanni Butte Dene Band”.)

In June 2011, the Company signed a separate Impact Benefits Agreement with the Liidlii Kue First Nation (“LKFN”) of Fort Simpson. The LKFN has agreed to support CZN in obtaining all necessary permits and other regulatory approvals required for the Prairie Creek Mine project. The Agreement is intended to ensure that CZN undertakes operations in an environmentally sound manner. LKFN will appoint a qualified Monitor to monitor environmental compliance and to monitor impacts of the Mine on the environment or wildlife and to work with CZN to prevent or mitigate such impacts. (See also “Description of the Business – Liidlii Kue First Nation”.)

The Nahanni Butte Dene Band and the Liidlii Kue First Nation are members of the Dehcho First Nations. Nahanni Butte is the closest community to the Prairie Creek Mine and LKFN is the largest member of the Dehcho First Nations. The Agreements provide a framework such that training, employment and business contracts, and some financial provisions are made available to the Nahanni Butte Dene Band and the LKFN to ensure maximization of benefits from opportunities arising from the Prairie Creek Project in a manner that will be to the mutual benefit of all parties.

The Prairie Creek Socio-Economic Agreement (See “Description of the Business – Socio-Economic Agreements”.) establishes the methods and procedures by which the Company and the Government of the Northwest Territories (“GNWT”) have agreed to work together to maximize the beneficial opportunities and minimize the negative socio–economic impacts arising from an operating Prairie Creek Mine.

Aboriginal Training Programs at Prairie Creek Mine Site

In a major new initiative Canadian Zinc launched four significant onsite training programs at the Prairie Creek Mine Site this year. These training programs were undertaken with assistance from the Federal Government, Human Resources and Skills Development Canada, in the $4.2 million “More Than a Silver Lining” aboriginal training program, specifically for the Prairie Creek Mine, administered by the NWT Mine Training Society and assisted by the Government of the Northwest Territories. These training programs included training for positions such as Office Administration, Mineral Exploration Field Assistant, Environmental Monitors, Heavy Equipment Operators, Diamond Drill Helper, Advance Medical First Responder and Camp Cook. The Silver Lining training program has trained 62 individuals with many of the graduates joining the staff at the Prairie Creek Mine, Canadian Zinc’s Fort Simpson office, or service providers to the Project.

Planning sessions are currently underway for new training programs in 2013, which are currently being planned and co-ordinated by the Company and the Mine Training Society which has opened an office and training centre in Fort Simpson.

Collaboration Agreement with Territorial Government

In August 2012, Canadian Zinc and the GNWT Department of Transportation signed a Collaboration Agreement to ensure effective co-operation related to the public transportation infrastructure that will support the Prairie Creek Mine project and will help ensure that both public needs and mine activities are supported.

Canadian Zinc plans to use the existing Northwest Territories public transportation system to bring goods, fuel and equipment by road to the Prairie Creek Mine and to transport its mineral products from the Prairie Creek Mine to world markets. As part of this Collaborative Agreement, to assist in priority setting, CZN will provide reports to the Department of Transportation on its anticipated road transportation requirements for the construction and operation of the Prairie Creek Mine which will help the Department of Transport to plan future work on these roads to maintain and enhance these roads effectively and the Department agreed to work closely with Canadian Zinc to ensure public safety by identifying areas of Highway 7 and the Nahanni Butte access road that require enhancement or upgrading.

Employees

In 2012, the Company had an annualized average of 25 employees. Ten employees were based in the Company’s corporate offices, three employees were based in a local Community Liaison Office and 12 employees were based at the Prairie Creek Mine site. In addition, the Company utilizes the services of contractors to assist in certain tasks and projects.

Acquisition of Paragon Minerals Corporation

On July 31, 2012, Canadian Zinc announced that it had entered into a binding arrangement agreement to complete a business combination as well as a non-brokered private placement with Paragon Minerals Corporation (TSXV: PGR). On September 24, 2012, Canadian Zinc acquired all of the outstanding common shares of Paragon in exchange for common shares of Canadian Zinc on the basis of 0.136 of a share of Canadian Zinc for each share of Paragon.

The acquisition has been accounted for as a purchase of assets and the assumption of liabilities by the Company. The transaction does not qualify as a business combination under IFRS 3, Business Combinations, as significant inputs and processes that constitute a business were not identified. Total consideration transferred was $4,345,000, which was comprised of the issuance of 7,299,019 common shares valued at $3,394,000 based on the closing market price of the Company’s shares on September 24, 2012 of $0.465 per share, conversion of options and warrants with a fair value of $53,000, Paragon shares amounting to 7,000,000 which were previously acquired and valued at $420,000 based on the closing market price of Paragon shares on September 24, 2012 of $0.06 per share and transaction costs of $478,000.

The purchase price was allocated to the assets acquired and the liabilities assumed based upon their estimated fair value at the date of acquisition. A value of $4,335,000 was allocated to exploration and evaluation assets for the mineral interests.

Paragon’s primary project is its 100% interest in the South Tally Pond Property, which includes the Lemarchant deposit, and is located in a proven mining district near Buchans, Newfoundland. The South Tally Pond Property covers 261 km2 and is immediately adjacent to Teck Resources Limited’s Duck Pond Cu-Zn mine and mill complex. The Lemarchant deposit is a significant precious metal-rich copper-lead-zinc Volcanogenic Massive Sulphide (“VMS”) discovery with a potential opportunity to develop into a viable economic resource. An initial NI 43-101 mineral resource estimate that was completed in March 2012 for Paragon on the Lemarchant deposit includes the following defined mineral resources:

·	Indicated resource estimate: 1.24 million tonnes at an average grade of 5.38% Zn, 0.58% Cu, 1.19% Pb, 1.10 g/t Au and 59.17 g/t Ag; and

·	Inferred resource estimate: 1.34 million tonnes at an average grade of 3.70% Zn, 0.41% Cu, 0.86% Pb, 1.00 g/t Au and 50.41 g/t Ag.

The Lemarchant deposit has been defined to a 210 m depth and remains open along strike and at depth. The exploration potential outside of the Lemarchant area of the South Tally Pond Property is still relatively untapped with numerous priority VMS targets that have seen limited or no drilling.

(See report entitled “NI 43-101 Technical Report and Mineral Resource Estimate on the Lemarchant Deposit, South Tally Pond VMS Project, Central Newfoundland, Canada” dated March 2, 2012 and filed on SEDAR under Paragon’s profile on March 9, 2012. (the “South Tally Pond Technical Report”))

South Tally Pond Property

The following information is reproduced from the South Tally Pond Technical Report and the detailed disclosure contained therein is incorporated into this AIF by reference:

Summary

This National Instrument 43-101 technical report documents exploration completed by Paragon Minerals Corporation (“Paragon”) on its 100% controlled South Tally Pond VMS Project (the “Property”) located in central Newfoundland. The exploration target is volcanogenic massive sulphide (“VMS”) similar to other VMS deposits in the area including the Buchans deposits and nearby Duck Pond deposit. The report covers exploration work completed by Paragon between September 2007 to September 2011 on the South Tally Pond Block of the South Tally Pond VMS Project. Highlights include an initial 43-101 compliant mineral resource estimate and preliminary metallurgical work completed on the Lemarchant Prospect.

This technical report was co-authored by Mr. David Copeland and Ms. Christine Devine of Paragon Minerals Corporation and Independent Qualified Persons Mr. Dean Fraser of RDF Consulting Ltd and Mr. Gary Giroux of Giroux Consultants Ltd. Mr. Fraser has relied on the information provided by Paragon and is responsible for all contents other than the resource estimation. Mr. Gary Giroux is responsible for the resource estimation portion of this report.

The South Tally Pond VMS Project is located 110 kilometres southwest of the town of Grand Falls-Windsor, NL and 35 kilometres south of the community of Millertown, NL. The Property consists of five, contiguous 100% controlled properties or blocks including the Harpoon Block, Gills Pond Block, Higher Levels Block, South Tally Pond Block and the South Tally Pond Extension Block. The aggregate land position comprises 8 map-staked mineral licences (856 claims) covering 21,400 hectares immediately southwest of the Duck Pond Mine. The South Tally Pond Block is under option from Altius Resources Inc., whereby Paragon can earn a 100% interest in this property by making one remaining share payment to the vendors. The Harpoon Block is subject to a 2% net smelter return royalty to the property vendors of which 50% is purchasable by Paragon.

The South Tally Pond project area has been explored intermittently since the late 1960’s for precious metal-rich polymetallic volcanogenic massive sulphide deposits. The bulk of the historic exploration work in the area was completed by Noranda and its various partners between 1973 and 1998. This exploration work resulted in the discovery of the Duck Pond and Boundary deposits.

In addition, Noranda discovered numerous other prospects including the Lemarchant, Rogerson Lake, Bindon’s Pond, Higher Levels, Spencer’s Pond and Beaver Lake Prospects through geochemical and geophysical surveys. Each of these areas has seen limited to no drilling.

The South Tally Pond Project is underlain by rocks of the Victoria Lake supergroup which consists of a structurally complex, composite collage of bimodal Neoproterozoic to Ordovician arc-related magmatic and sedimentary rocks. The Victoria Lake supergroup hosts numerous base metal-bearing VMS deposits, showings and extensive alteration zones, and several gold deposits and showings. This mineralization is distributed throughout all of the lithotectonic assemblages, including the Tally Pond Volcanic Belt, that comprise the supergroup. The Tally Pond Volcanic Belt consists of Cambrian-aged volcanic, volcaniclastic and sedimentary rocks that extend from Victoria Lake northeast to Burnt Pond. The South Tally Pond Project is situated in the same volcanic belt and to the immediate southwest of Teck Resources Limited’s Duck Pond CopperTechnical Report and Mineral Resource Estimate on the Lemarchant VMS Deposit Zinc Mine (5.1 million tonnes averaging 3.6% Cu, 6.3% Zn, 1.0% Pb, 64 g/t Ag and 0.9 g/t Au for both the Duck Pond and Boundary deposits).

The Lemarchant Deposit area is underlain by a north-striking sequence of bimodal submarine volcanic rocks (rhyolites and basalts) of the Tally Pond Volcanic Belt. The mineralization is hosted within a 4,000 metre long and 700 metre wide sequence of highly altered felsic volcanic rocks. Polymetallic sulphide mineralization is hosted in moderate to intensely altered rhyolite breccias, massive flows and lesser tuffaceous horizons. The footwall to the semi-massive to massive sulphide mineralization is characterized by a well developed, barium-enriched base metal stringer system, with moderate to intense quartz-sericite-chlorite to quartz-chlorite alteration. On several sections the footwall alteration zone is cut-off by a frequently recognizable, east-verging thrust fault (Lemarchant Fault) that potentially repeats the mineralized horizon at depth in the minimally tested Lower Felsic Block. The Lower Felsic Block represents an area of high exploration potential that warrants aggressive follow-up drilling.”

South Tally Pond 2013 Drill Program

In January, 2013, the Company initiated a 4,800 metre drill program focused on expanding the NI 43-101 resources at the Lemarchant deposit. The planned program includes up to 17 drillholes that is focused on further expanding the Lemarchant Deposit mineralization. As of February 21, 2013, the Company completed 1,522 metres of drilling in four diamond drillholes targeting the Lower Felsic Block on Section 106N.

The first two drillholes, LM13-73 and LM13-74, were aimed at extending the massive sulphide mineralization intersected in a 2008 drillhole (LM08-37) to the east. The 2008 intercept is located 300 metres to the northwest of the Lemarchant Deposit, and was not included in the initial NI 43-101 mineral resource.

LM13-73 intersected a well mineralized interval between 302.2-350.2 metres downhole (47.4 metres) approximately 40 metres east (up-dip) of LM08-37. The mineralized interval contains semi-massive to massive base metal sulphide zones and mineralized massive barite zones. Significant assay results include 5.82% zinc, 1.48% lead, 0.75% copper, 65.4 g/t silver and 1.63 g/t gold over 22.2 metres.

LM13-74 intersected a similar, well mineralized interval between 296.2-334.0 metres downhole (37.8 metres) and 35 metres east (up-dip) of LM13-73. The mineralized interval contains semi-massive to massive base metal sulphide zones and a mineralized massive barite zone. Significant assay results include 5.33% zinc, 1.01% lead, 0.75% copper, 44.72 g/t silver and 0.26 g/t gold over 5.50 metres.

The newly extended zone remains open along strike with no drilling immediately north or south of the new drillholes.

Drillhole LM08-28 EXT extended a 2008 drill hole (LM08-27) from a drilled depth of 262 metres to 485 metres. The drillhole extension intersected 94 metres of altered felsic volcanic rocks with minor disseminated and stringer base metal mineralization.

Drillhole LM13-75 remained in basalt over its entire length (539 metres) and did not reach the targeted Lower Felsic Block.

Vatukoula Gold Mines plc

In 2009, the Company acquired an interest in Vatukoula Gold Mines plc (“VGM”). Canadian Zinc currently holds 12,573,380 shares of VGM, which represents approximately 10.7% of the issued share capital of VGM. VGM is a UK company, listed on AIM (part of the London Stock Exchange), which currently owns and operates the Vatukoula Gold Mine located in Fiji.

The shares of VGM were acquired for investment purposes. Depending on the performance of the Vatukoula mine and on market and other conditions, Canadian Zinc may from time to time in the future increase or decrease its ownership, control or direction over the shares of VGM, through market transactions, private agreements or otherwise.

Zazu Metals Corporation

In December 2009, Canadian Zinc acquired 3.4 million shares of Zazu Metals Corporation (“Zazu”) representing approximately 11% of Zazu’s outstanding shares, for consideration of $646,000. Zazu is listed on the TSX and its principal asset is the LIK zinc-lead-silver deposit, located in northwest Alaska, 22 kilometres from Teck Resource’s Red Dog Mine, the world’s largest zinc producer. In December 2010, Canadian Zinc sold 3.4 million shares of Zazu and does not currently hold any shares of Zazu.

DESCRIPTION OF THE BUSINESS

The Company’s principal focus is exploration and development of the Prairie Creek Property and adjacent ground (a zinc/lead/silver, partially developed property) located approximately 500 kilometres west of Yellowknife in the Northwest Territories, Canada. The Mine is believed to be one of the highest grade non-operating base metal properties in the world and is potentially a major Canadian resource.

The primary objectives of the Company are to rehabilitate, upgrade and modernize the Prairie Creek Mine, inclusive of the processing plant and related site infrastructure, secure sales agreements for future concentrate production, and secure the necessary operating permits so as to bring the Prairie Creek Mine into production at the earliest opportunity.

History

The original discovery of mineralization on the Prairie Creek Property was made in 1928 at the showing known as the “No. 5 Zone.” In 1958, a limited mapping program was undertaken by Fort Reliance Minerals Ltd. The claims lapsed in 1965 and were restaked by the prospector and subsequently conveyed to Cadillac Explorations Ltd. (“Cadillac”) in 1966. Cadillac also acquired a 182,590 acre prospecting permit.

During 1966 to 1969, trenching was carried out by Cadillac on a number of zones and underground exploration commenced. The prospecting permit expired in 1969 and 6,659 acres (210 claims) were selected by Cadillac and brought to lease. The property was optioned to Penarroya Canada Ltee. (“Penarroya”) in 1970 and the underground development was extended. Surface drilling and preliminary metallurgical testing was also conducted. Penarroya discontinued their work in late 1970 and Cadillac resumed full operation of the project. Cadillac further developed the underground workings and resampled the crosscuts in 1979.

In 1980, an independent feasibility study was completed for Cadillac by Kilborn Engineering which resulted in a decision to put the property into production. In December 1980, Procan Exploration Company Ltd. (“Procan”) (a company associated with Herbert and Bunker Hunt of Texas) agreed to provide financing for construction, mine development and working capital necessary to attain production based on the Kilborn feasibility study. Between 1980 and 1982, extensive mine development took place. Cadillac acquired a 1,000-ton per day mill concentrator and transported it to the minesite. The mill was erected and a camp established. Two adits and extensive underground workings were developed. During this time the winter road connecting the mine to the Liard Highway was constructed and over 500 loads of supplies were transported to site. Construction activities continued until May 1982 and were almost complete when they were suspended due to lack of financing. Subsequently, Cadillac went into bankruptcy in May 1983 and site maintenance and operations were taken over by Procan.

In 1991, Nanisivik Mines Limited (an unaffiliated third party) acquired the property through the bankruptcy proceedings. Pursuant to an August 23, 1991 Option Agreement, the Company entered into an option to acquire a 60% interest in the Prairie Creek Property from Nanisivik Mines Ltd. Subsequently, pursuant to a March 29, 1993 Asset Purchase Agreement that superseded the Option Agreement, the Company acquired a 100% interest in the Prairie Creek Property, and a 60% interest in the plant and equipment, subject to a net smelter royalty of 2% in favour of Titan Pacific Resources Ltd. In January 2004, the Company acquired all of Titan’s interest, including the 2% net smelter royalty, and now holds a 100% interest in the Prairie Creek property, plant and equipment.

Between 1991 and 2000, the Company carried out various exploration programs on the Prairie Creek Property. In January 2001, the Company completed a Scoping Study designed to outline and guide the re-development of the existing mine and mill on the Prairie Creek Property. The preliminary study indicated the feasibility of a mining and milling operation on the site and identified a number of different development and production scenarios. The operation would utilize the existing mine and mill infrastructure that had been put in place in 1982, but which had never been operated. Indicated capital costs for the new operation were estimated in 2000 to be $40.5 million, including the construction of an all-weather access road to the site. The Scoping Study has not been updated and is now considered to be out of date. It is now anticipated that the capital costs to place the Prairie Creek mine into production will be significantly higher than indicated in the 2001 Scoping Study.

In 2006 and 2007, the Company carried out an underground exploration program, driving a decline about 550 metres and completing approximately 10,600 metres of underground drilling. In October 2007, an updated Technical Report (the “Minefill Report”) with regard to Mineral Resource Estimation on the Main Zone at Prairie Creek was independently prepared by Minefill Services Inc. in compliance with National Instrument 43-101, following the results of the 2006/2007 underground drilling program. The Minefill Report verifies and confirms the previous historical resource estimate completed by MRDI in 1998 and notes significant upgrades in resource categories. The Minefill Report indicates that the Prairie Creek Property hosts total Measured and Indicated Resources of 5,840,329 tonnes grading 10.71% zinc, 9.90% lead, 161.12 grams silver per tonne and 0.326% copper. In addition, the Minefill Report confirms that there is also a large Inferred Resource of 5,541,576 tonnes grading at 13.53% zinc, 11.43% lead, 215 grams per tonne silver and 0.514% copper and additional exploration potential.

A Project Description Report (“PDR”) was prepared and filed with regulatory authorities in May 2008 in support of application for operating permits. The PDR describes in detail the proposed new mining operations at Prairie Creek and contemplates the construction of new facilities including new fuel-efficient/low-emission power generating units, a kitchen/accommodation block, concentrate storage shed, an incinerator, a new engineered waste rock pile and two new transfer stations along the winter road.

In December 2011, The Review Board issued its Report of Environmental Assessment and Reasons for Decision for Canadian Zinc’s proposed Prairie Creek Mine (the “EA Report”). The Review Board concluded the proposed development is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern, an environmental impact review of the proposed development is not necessary and the project should proceed to the regulatory phase for approvals. In June 2012, the Minister of Aboriginal Affairs and Northern Development advised the Review Board that an environmental impact review of the proposed development of the Prairie Creek Mine is not necessary.

In December 2011, an updated Technical Report Prairie Creek Mine, Northwest Territories Canada, December 28, 2011 (the “2011 Technical Report”) was prepared by Alan B. Taylor, (P.Geo), a Qualified Non-Independent Person in compliance with National Instrument 43-101. The 2011 Technical Report verifies and confirms the Minefill Report and notes no change in the Mineral Resources since 2007. The 2011 Technical Report indicates that the Prairie Creek Property hosts total Measured and Indicated Resources of 5,840,329 tonnes grading 10.71% zinc, 9.90% lead, 161.12 grams silver per tonne and 0.326% copper. In addition, the 2011 Technical Report confirms that there is also a large Inferred Resource of 5,541,576 tonnes grading at 13.53% zinc, 11.43% lead, 215 grams per tonne silver and 0.514% copper and additional exploration potential.

In January 2012, following the completion of the Environmental Assessment in December 2011, the Water Board commenced the regulatory process for the issue of a Class “A” Water Licence and Land Use Permits for the operation of the Prairie Creek Mine. In February 2012, the Company submitted a CPD, highlighting the changes that resulted from commitments made by Canadian Zinc during the environmental assessment process.

The Water Board completed its review of the information contained in the application, Environmental Assessment and the CPD and in May 2012, issued a Directive on the additional information required by the Water Board at this stage of the Regulatory Process.

In June 2012, a Preliminary Feasibility Study prepared by SNC-Lavalin Inc. of Vancouver was submitted to the Company. This report contains capital cost estimates for the rehabilitation and upgrading of the mill, power plant and water treatment plant, and for new water storage ponds. It includes an engineering procurement and construction management plan, as well as working cost estimates for mining, processing and transportation. A comprehensive cash flow model was designed to estimate the economics of the proposed operation. The report indicated a pre-tax NPV, using an 8% discount, of $253M, with an IRR of 40.4% and payback period of three years, with an 11 year mine life, and pre-production capital costs totaling $193M.

In August 2012, a new independent Mineral Resource statement in the AMC Technical Report was completed by Qualified Persons (“QP”), as defined by NI 43-101, J. Morton Shannon, P.Geo., Dinara Nussipakynova, P.Geo. of AMC, JB Hancock, P.Eng. of Barrie Hancock & Associates Inc. and B. MacLean, P.Eng. of SNC-Lavalin Inc. reporting a Measured and Indicated resource of 5.43 million tonnes at a grade of 10.8% Zn and 10.2% Pb with 160 g/t Ag per tonne and an Inferred resource of 6.24 million tonnes at a grade of 14.5% Zn and 11.5% Pb with 229 g/t Ag per tonne (see AMC Technical Report filed on SEDAR). In October 2012, the Company filed its response to the Water Board and in a further submission in November incorporated the results of additional water quality/treatment studies received from SGS Lakefield and CEMI Labs. Due to the necessary time required to complete the lab testing program the Water Board revised the original work plan.

Formal written interventions to the MVLWB were submitted by the Intervening Parties on January 11, 2013 and CZN submitted a response to the Interventions on January 18, 2013. Beginning January 29, 2013, the Company and Intervenors attended Public Hearings held in Fort Simpson. The three day session was adjudicated by the Water Board. A Public Hearing scheduled to be held in Nahanni Butte February 1, 2013 was postponed due to weather and held as a teleconference on February 8, 2013. Final closing statements by all Intervenors were filed on February 15, 2013 and the Company filed its’ closing statement February 22, 2013.

On March 15, 2013 the Water Board issued a Draft Type “A” Water Licence and two Draft Type “A” Land Use Permits for the operation of the Prairie Creek Mine.

Documentation related to this regulatory process is posted on the Water Board website at www.mvlwb.ca/mv/registry.aspx (Year 2008, Canadian Zinc MV2008L2-0002).

Principal Property – Prairie Creek, Northwest Territories

The information relating to the Prairie Creek Property in the following sections has been extracted from the AMC Technical Report dated June 15, 2012 (file August 9, 2012) and prepared by QPs, as defined by NI 43-101, J. Morton Shannon, P.Geo., Dinara Nussipakynova, P.Geo. of AMC Mining Consultants Ltd., JB Hancock, P.Eng. of Barrie Hancock & Associates Inc. and B. MacLean, P.Eng. of SNC-Lavalin Inc.

This Technical Report discloses the results of a Preliminary Feasibility Study which has been carried out to assess the viability of starting up the Prairie Creek Mine. The report incorporates the Mineral Resources and Mineral Reserves as at 31 May 2012, which are similar to those resources disclosed in an earlier Technical Report entitled Technical Report, Prairie Creek Mine, Northwest Territories, Canada, by A B Taylor P.Geo. of Canadian Zinc, dated 28 December 2011 (2011 Technical Report). The 2011 Technical Report was in turn based on a 2007 Technical Report entitled Technical Report on the Prairie Creek Mine, Northwest Territories, Canada, prepared by David M.R. Stone, P.Eng. and Stephen J. Godden, FIMMM., C.Eng. of MineFill Services, Inc (2007 Technical Report). This is the first disclosure of Mineral Reserves on the Property.

History, Location and Ownership

The Prairie Creek Property contains a high-grade, silver-lead-zinc-copper vein that was explored since the early 1900s and then extensively explored and developed by Cadillac Explorations Limited (Cadillac) f r o m 1966 to 1983. A mine was developed and the processing plant and surface infrastructure were built in the early 1980s, at a cost of C$64 million (1982 money). The operations were engineered and fully permitted to produce and process mineralized vein material at a rate of 1,000 tons per day. The 1982/83 fall in metal prices necessitated closure of the mine prior to production. This closure led to a change of ownership and eventually to the Company’s involvement in 1992. Through a series of agreements between 1992 and 2004 the Company established an increasing interest in the property, plant and equipment resulting in a 100% interest in the Property by 2004.

The Property consists of two surface leases, twelve mining leases and one mineral claim totalling 8,218 hectares. Its assets include the Mine, a processing plant, various mine- and plant-related surface infrastructure, various earth moving and mining equipment and numerous mineralized occurrences that are at various stages of exploration and development.

Since acquiring the property in the 1990s, CZN has invested over $45 million, quadrupling the known mineral resource and moving the project through six environmental assessments of various development stages, including, most recently, the proposed operation of the Mine, and obtaining numerous exploration and development permits and licences.

The Property is situated approximately 500 km west of Yellowknife in the Mackenzie mountain range that has an average relief of approximately 300 m and comprises low mountains with moderate to steep sides and intervening narrow valleys, at an elevation of 850 m above mean sea level. The Property is surrounded by, but is not included in, the Nahanni National Park Reserve.

Year round access to the Property is provided by aircraft to a 3,000-foot gravel airstrip immediately adjacent to the camp. The Property is also accessible by an access road which extends from the Property to the Liard Highway, a distance of 170 km and which was originally permitted for use in the winter months throughout its full length and for year round use for the first 40 km out from the mine site. The Company has been granted a Land Use Permit by Parks Canada for the use of the portion of the road within Nahanni National Park Reserve and has been granted a Land Use Permit by the Mackenzie Valley land and Water Board for the remainder of the road. The road needs to be re-established, and the Company successfully rehabilitated approximately 30 km out from the mine site in the summers of 2008 and 2009. The Liard Highway #7 is the major north-south transportation route, which connects Fort Simpson, Northwest Territories to Fort Nelson, British Columbia.

The primary objectives of the Company is to bring the Mine into production at the earliest opportunity and in pursuit of that objective, to rehabilitate, upgrade and modernize the Mine, inclusive of the processing plant and related site infrastructure, and secure the necessary operating permits.

Geology and Mineralization

The Property geology is dominated by Siluro-Devonian stratigraphy that formed in a paleo-basin adjacent to the ancient North American Platformal sediments. The east-dipping and west-dipping thrusts, define the present margins of the Prairie Creek paleo-basin in which sediments accumulated.

Units within the Prairie Creek paleo-basin underwent structural deformation in the form of folds and faults during regional Laramide deformation. The prevalent regional structural trend is approximately north-south; the Prairie Creek paleo-basin is broken into a series of north-south trending, five to 20 kilometre fault blocks. Canadian Zinc’s mineral claims and leases overlie two major fault blocks of sediments: the Prairie Creek Block and western Gate Block.

The Prairie Creek block is located on the southern part of the Property. It is outlined by a one to two kilometre wide, doubly plunging antiform with a north-south trending fold axis. It is underlain by a conformable sedimentary sequence ranging from Lower Ordovician to Silurian in age. The antiform plunges at about 15 degrees to the north, so the geological units young in age to the north.

The mine site is situated on the western flank of the Prairie Creek antiform, referred to as the Main Zone. It is Main Zone mineralization that was and is the focus for mine development and exploitation. The Ordovician, Upper Whittaker Formation is the oldest geological formation in this area. It is composed of interbedded cherts and dolomites that form the core of the Prairie Creek antiform. The Whittaker Formation is in turn overlain by a large exposure of the carbon-rich graphitic-shales/dolomites of the Road River Formation. The iron-bearing Cadillac Formation shales overly the Road River Formation and are located immediately adjacent to the mine site. The bluff-forming rocks immediately to the west of the mine site are formed by the cherty Arnica Formation which overlies the Cadillac Formation and forms the more resistant hilltops in the immediate vicinity of the Mine site.

The Gate Block is located to the west of the main mining leases and overlies similar type rock assemblages to those found on the Prairie Creek Block. Grassroots exploration was completed on this ground to test for mineralization similar to that found in the Prairie Creek Block.

Four main styles of base metal mineralization have been identified on the Property: vein mineralization, stratabound sulphides (SMS), stockwork (STK) and Mississippi Valley type (MVT) mineralization. Base metal mineral showings occur along the entire 16 kilometre north to south length of the Property.

The most significant mineralization on the Property is the vein mineralization. Vein mineralization comprises massive to disseminated galena and sphalerite with lesser pyrite and tennantite-tetrahedrite in a quartz-carbonate-dolomite matrix. Secondary oxidation is locally developed to variable levels of severity, yielding mainly cerussite (lead oxide) and smithsonite (zinc oxide). Silver is present in solid solution with tennantite-tetrahedrite and to a lesser extent with galena. Vein widths vary between less than 0.1 metre and more than 5 m. Overall averages indicate a horizontal thickness, but not a true thickness, of approximately 2.7 m.

The most extensively developed vein is the Main Quartz Vein (MQV). Underground development has proved 940 m of strike length and diamond drilling to date has indicated its continuance for a further 1.2 km. The MQV trends approximately north-south and dips between the vertical and 40 degrees east with an average dip of 65 degrees east. It remains open to the north and evidence from a surface showing suggests it continues for a further four km to the south. Diamond drilling to depth has indicated its continuance, but little information is currently available below an elevation of 600 m amsl (i.e. about 250 m below the Mine Site elevation).

Stockwork (STK) mineralization occurs as a series of narrow massive sphalerite-tennantite veins developed at about 40 degrees difference in strike to the average trend of the MQV. This mineralization has developed in sub-vertical tensional openings formed by primary movement along the main vein structure. The sulphide mineral assemblages are similar to those outlined for MQV material. To date, the STK mineralization has only been located in around the exposure on the 930mL underground workings.

Stratabound (SMS) mineralization occurs at depth beneath the trend of the Prairie Creek Vein System over a strike length of more than 3 km. SMS mineralization occurs close to both the vein system and the axis of the Prairie Creek anticline. An apparent thickness of 28 m of SMS mineralization has been intersected in Main Zone drillholes where it occurs approximately 200 m below 870 metre Level. The vein structure cuts through the SMS indicating the vein mineralization to be younger.

SMS mineralization is generally fine-grained, banded to semi-massive and comprises massive fine-grained sphalerite, coarse-grained galena and disseminated to massive pyrite and very little copper. SMS contains only half as much galena, but substantially more iron sulphide/pyrite than typical vein material. Silver is contained in solid solution within galena.

The MVT mineralization found on the Property is comprised of colliform rims of sphalerite, brassy pyrite-marcasite and minor galena, with or without later dolomite infilling. The mineralization appears to occur discontinuously within coarse biohermal reefs of the Root River Formation, and always at approximately the same stratigraphic horizon. It appears to be classic MVT mineralization, insofar as it occurs in open cavity-type settings.

Exploration and Data Management

The Company has been involved with semi-continuous exploration activity across the Property since 1992. Limited exploration drilling had been undertaken prior to the Company’s initial involvement in 1992. Up to November 2011, the Company had completed a total of 261 surface and underground exploration diamond drillholes totalling 68,744 m of coring. 251 channel samples over 322 m were also completed.

The main focus of exploration and underground development work has been on Main Zone mineralization. A deep drilling exploration program was carried out during 2010/11 seasons to test for the northerly extension of the defined resource. This program successfully intercepted what appears to be the same mineralized structure one and a half km north along plunge of the resource bearing geology.

Since 1992, surface diamond drilling has been carried out using skid-mounted, Longyear Super 38 drills owned by CZN to recover NQ diameter (47.6 mm) core. This is reduced to BQ size (36.5 mm) if difficult downhole conditions are experienced. In 2010 a new higher capacity HTM-2500 diamond drill rig was airlifted to the property for use in the deep drilling program. Average core recoveries are variable and in 2007 ranged between 97% recovery in the SMS mineralization to 80% for the MQV mineralization. Core recoveries have been consistently recorded since 2006. Bulk density measurements have been obtained through direct measurement and calculations. While acceptable for the purposes of this report, AMC recommends that this area be reviewed prior to the next block model.

Drill samples and underground channel samples are air-freighted, in charter aircraft, from the Mine Site airstrip to Fort Nelson, B.C., from where they are transported by Greyhound bus to the assay laboratory (Acme Labs, ISO 9001-2000 accredited) in Vancouver, B.C. Acme Labs (ISO 9001-2000 accredited) has carried out the majority of the sample assays since the Company’s first involvement in 1992. It is currently the only laboratory used by the Company for purposes of sample assaying. The grades of silver, copper, lead and zinc, as well as 30 additional elements, are determined for all samples by aqua regia digestion followed by an ICP finish.

Quality Assurance/Quality Control (QA / QC) samples are submitted by CZN with the regular samples for analysis, including blanks, duplicates and blind standards. Blank and duplicate samples are taken every ten drillcore samples; standards are sent, at the supervising geologist's discretion, after a mineralized zone is sampled. AMC believes that the data collection and handling followed normal industry practice and the data is fit for purpose. However, while QA/QC samples were inserted and the results have been observed in the historical assay certificates, it is not clear if any analysis of the historical data was carried out. This has been remedied in the recent programs but these do not influence the current Mineral Resource.

Mineral Resources and Mineral Reserves

The existing Mineral Resource discussed in the 2011 Technical Report, which was based on the 2007 Technical Report, was reviewed and restated by AMC. This estimate is based on the same data as that of 2007. Minimal work has been carried out within the Main Zone resource area since 2007. A reclassification from the Indicated to Inferred category of a multiple high-grade drill intercept at the northern end of the resource model has resulted in a slight overall reduction in the tonnes and grade of the Indicated category and a slight increase in the Inferred category.

The database comprises both underground and surface drill holes in addition to channel samples collected by the Company since 1992. Channel samples are treated as drillholes. A total of 224 drillholes and 943 channel samples were used in the resource estimate.

Two block models were created: 1) encompassing the MQV and STK solids and 2) for the SMS solid. Block values were computed by the inverse distance to the second power (ID2) in all cases. Three passes were performed for zinc, lead and silver for SMS, and included copper in the case of MQV and STK. Specific gravity was interpolated from collected data for the MQV and SMS, while the STK was assigned a value of 3.31.The summary results of the estimate for the three zones combined, at a cut off of 8% Zn equivalent (Zn Eq) are shown in Table 1 below.

The Prairie Creek deposit contains a significant amount of Inferred Resources which, upon further delineation, has the potential to double the life of the mine.

A portion of the Mineral Resources was converted to Mineral Reserves through application of suitable dilution factors in stoping blocks (averaging 22% for MQV and 10% for SMS) utilizing the cut-and-fill mining method for MQV and room and pillar for SMS. A Mineral Reserve of 5.2 million tonnes, grading 9.4% Zn and 9.5% Pb, with 151 g/t Ag has been estimated.

Due to the high grade nature of the deposit, the majority of the vein resource will be mined, allowing for 97% of all of the Measured and Indicated vein resources to be converted to Mineral Reserves and 57% of all Measured and Indicated Resources within the SMS mineralization to be converted to Reserves.

Mining

The Mine will be an underground operation primarily based on the MQV. Three levels of underground adits (970 mL, 930 mL, 880 mL, collectively known as the upper mine) have already been established and these are targeted to be mined early in the life of the proposed operation. As mining progresses to depth, mining feed generated from the MQV will be supplemented by the deeper SMS deposit, both deposits being also accessed by a single ramp development.

Mining will be conducted primarily using mechanized cut-and-fill on the narrow vein structure, with potential use of the room-and-pillar mining method on the SMS material. The previously developed shrinkage stopes will be converted to the cut-and-fill method. Paste backfill will be used and the aim is to use 100% of flotation tailings in the backfill. An average mining rate of 1,350 tonnes per day of ore is targeted. During full production, approximately 500,000 tonnes of ore per year will be mined over an 11 year life of mine.

Access to the mine will be primarily through the existing 870 portal. Underground development, existing from the 1980s will be fully utilized to help minimize the amount of pre-development required to achieve mine operation. Limited geotechnical work within the mine has been conducted to date. Ground conditions in existing development underground are good and the existing workings have stood unsupported for close to 30 years with minimal bolting. A geotechnical program has been planned for the summer of 2012 to confirm the geotechnical characteristics of the lower mine.

The MQV structure constitutes the main conduit for water to access the mine, and significant quantities of water pass through the vein. The Mine will be wet and managing groundwater will be a significant aspect of the operation. Presently natural groundwater drains out of the 870 mL portal during the summer season at an average of 20 litres per second (L/s). When in full production, the Mine is estimated to produce up to 100 L/s of water. All water discharged from the mine will either be sent to the mill as feed water or be pumped into the currently existing tailings pond facility which will be revised and converted into a Water Storage Pond and then sent to the proposed new water treatment plant.

Underground development prior to production will comprise of tunnel enlargement and extension at various points of the existing levels. Stope access development and installation of service utilities will also be conducted during pre-production. The pre-production phase is expected to take approximately 12 months and be performed by a contractor. All remaining major development within the mine will be finished by the end of year 5 (after four years of production) and will be conducted by the owner.

In order to achieve 100% disposal of tailings underground, no development rock will be left underground. Only dense media separation float material waste rock will be placed back in the mine, as aggregate for paste backfill running surfaces. There will be a need to temporarily store tailings during times when there are limited stopes available for backfill. Although the waste rock is considered Non-Acid Generating (NAG) due to its high content of carbonate material, appropriate precautions will be taken to prevent and mitigate any leaching that occurs from surface runoff through the waste rock pile.

Currently on site there exists close to 50,000 tonnes of oxidized mineralized material stockpiled at surface. Further assessment of this stockpile is warranted before any revenue can be allocated towards it since it has been broken and exposed on surface for over 30 years.

Metallurgy, Processing

Metallurgical tests conducted to date proved positive and generated satisfactory simulated results of anticipated actual operations in the production of mineral concentrates at the Mine. Good metal recoveries can be achieved in both sulphide and oxide material, with a reagent suite that does not include cyanide products. The test results showed marketable concentrates can be produced although penalty elements, including antimony, arsenic and mercury, would unavoidably report to the final concentrates.

The test results indicate that the anticipated overall grade of the blended lead sulphide/oxide concentrate assayed 67% lead, with an 88% recovery of total lead in the plant feed, and the zinc sulphide graded 58% Zn with a 75% recovery of the total zinc in the plant feed. An average of 92% of the total silver values in the plant feed was recovered within the lead and zinc concentrates.

As the Mine was fully permitted, though never achieved production, existing infrastructure is substantial. It includes a processing plant that was 90% complete at mine closure in 1982, and a 1.5 million tonne capacity tailings impoundment, power plant, and water treatment plant. There are plans to rehabilitate and upgrade the processing plant, power plant, and water treatment plant.

The current mill facilities have a 1,500 tpd crushing capacity, with an installed jaw crusher, short head cone crusher, double-decked screen and a 2,000 t ore bin.

A new dense media separation (DMS) circuit, at 85 tph capacity, will be installed into the crushing circuit to process -1/2” sized material. Indications from metallurgical testing are that the DMS plant will reject an average of 27% of the waste at minimal metal losses, hence mining input at production rates will be 1,350 tpd and, after passing through DMS plant, will produce approximately 1,000 tpd of material to be processed in the grinding/flotation circuit of the mill.

Infrastructure

Five new 1.5 MW diesel powered generator units will provide power and heat for the site. These self-contained, pre-commissioned power generator units will be located adjacent to the mill. Maximum power load for the site is estimated at 4,674 kW and diesel fuel will be the primary energy source required to operate the generators. These generators will be outfitted with heat recovery systems in order to maximize energy efficiency. The waste heat from the generators will be used to heat the surface facilities.

100% of the tailings from the mill will be placed permanently underground in a form of paste backfill mix generated from the new paste backfill plant. The remainder of the DMS reject and mine development waste will report to a Waste Rock Pile Facility, located 700 m behind the mill off the Prairie Creek floodplain.

A detailed transportation plan and schedule has been developed incorporating use of winter road access and transfer facilities. New storage facilities will be built at site to temporarily store concentrate when the winter road opens. The Tetcela Transfer Facility will be established at a mid-point along the access road as a temporary storage area for concentrate prior to the ice bridge being established each winter over the Liard River. The Liard Transfer Facility located on the NWT highway system will act as an inbound/outbound storage area for both supplies and concentrate and for all-season access to railhead in Fort Nelson, B.C., where a rail siding facility is planned. All building costs have been incorporated into the PFS.

The 184 km long winter road with two transfer facilities will provide temporary surface access to the site for a minimum of 60 days of the year.

Formal smelter arrangements have not been agreed to at the present time; however, normal course treatment charges and penalties for deleterious elements have been applied.

Environmental and Social Issues

In December 2011, the Mackenzie Valley Environmental Impact Review Board (the Review Board), the primary authority responsible for all environmental assessment and review throughout the Mackenzie Valley in the Northwest Territories, approved the proposed operation of the Mine. The Review Board issued its Report of Environmental Assessment and Reasons for Decision for the Company's proposed Prairie Creek Mine (the EA Report) and submitted the Report and Decision to the Federal Minister of Aboriginal Affairs and Northern Development.

The Review Board concluded that the proposed development of the Mine, including the list of commitments made by the Company during the proceedings, is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern. The Review Board therefore concluded that an environmental impact review of this proposed development is not necessary and that the Mine project should proceed to the regulatory phase for approvals.

In a Decision dated June 8, 2012, the Minister of Aboriginal Affairs and Northern Development, on behalf of the responsible Ministers with jurisdiction, including the Minister of the Environment, the Minister of Fisheries and Oceans, the Minister of Environment and Natural Resources, the Minister of Transport Canada and the Minister of Environment and Natural Resources of Government of the Northwest Territories, advised the Review Board of the Decision that the Ministers will not order an environmental impact review of the proposed development of the Prairie Creek Mine, nor will they refer the proposal to the Minister of the Environment for a Canadian Environmental Assessment Act joint panel review.

In May 2012, the Mackenzie Valley Land and Water Board (MVLWB) also issued a work plan indicating that a draft “A” Water Licence for Prairie Creek should be issued for review by end of 2012.

A detailed socio-economic assessment was completed in support of the Project. The study concluded that the Prairie Creek Mine will be a relatively modest project in a region of the NWT that has limited confirmed economic prospects. The majority of the economic and social impacts will be generated through the participation of local labour and business in the area, including the communities of Nahanni Butte, Fort Simpson and Fort Liard.

In 2011, Canadian Zinc signed important Impact and Benefits Agreements with each of Nahanni Butte Dene Band and Liidlii Kue First Nation (Fort Simpson), both part of the Dehcho First Nations. Later than year, CZN negotiated a Socio-Economic Agreement with the Government of the Northwest Territories (GNWT), covering social programs and support, commitments regarding hiring and travel, and participation on an advisory committee to ensure commitments are effective and are carried out.

Economic Analysis

An economic analysis with a +/- 10% sensitivity factor centering on the Base Case outlines the average annual EBITDA, NPV, IRR payback period and are shown on a pre-tax and pre-finance basis in Table 6. The base case shows a Pre-tax Net Present Value, using an 8% discount, of $253 M, with an internal rate of return of 40.4% and payback period of three years. Metals prices used were US$1.20 /lb in the short term and US$1.00 /lb in the long term for both lead and zinc, and US$28.0 /oz in the short term and US$26.0 /oz in the long term for silver.

* Annual average EBITDA does not include year 1 of production

Within the cash flow model, revenue is recognized as the concentrate is generated and does not account for any time delay between shipment and payment for concentrate.

The pre-tax IRR is sensitive to zinc, lead and silver prices as well as to capital and operating costs on a percentage basis.

Risks and Opportunities

Major Risks:

·	Significant reduction in metal prices.

·	Increase in fuel cost significantly in excess of offsetting increases in metal prices.

·	A shortened winter road hauling season that could affect the ability to complete the annual concentrate removal and mine re-supply.

·	Periods of abnormally cold weather over extended periods of time creating surface-related operating problems.

·	Paste delivery sequencing problems creating surface storage issues inconsistent with operating permits.

·	Water treatment plant disruption which may cause effluent quality outside compliance limits necessitating the temporary suspension of operations.

Major Opportunities:

·	Continued road upgrades and bridge installations that would reduce winter road installation and maintenance costs and also decrease transport costs.

·	Cycloning of the DMS feed screen undersize to upgrade feed to the grinding circuit.

·	Copper / lead separation to produce a Cu/Ag concentrate that could be air-shipped all year around from the site.

·	Use of a form of longhole / sublevel stoping rather than cut and fill in zones of wider mineralization which could reduce operating costs, increase mine productivity and allow for more tailings to be stored underground (less cement required during backfill).

·	Use of higher capacity underground equipment to increase efficiency and productivity Reduction in mine dilution in the next stage of design.

Other Relevant Data

The Project is located close to (but outside of) the Nahanni National Park Reserve. In 2009, the Nahanni National Park Reserve was expanded to surround, but exclude, the Prairie Creek Mine, and access to the Prairie Creek area was protected in an amendment to the Canada National Parks Act.

CZN has an existing MOU with Parks Canada regarding the operation and development of the Prairie Creek Mine and the management of the Nahanni National Park Reserve.

Recommendations (with estimated cost where relevant)

Project optimization

There are a number of recommendations listed in the PFS including:

·	Examine opportunities to improve efficiencies in transport, scheduling and logistics on the winter road.

·	Consider financial alternatives to purchasing of significant equipment and other procurement.

·	Review opportunities for early completion of construction, engineering and mine development programs to reduce start-up times required.

·	Consider financial arrangements targeted to further reduce Working Capital needs.

·	Undertake additional drilling programs, particularly towards the north end of the deposit, to increase the confidence level in the estimated resources and reserves and to identify additional resources. $2 million

·	Modify the mine plan to include increased resources and identify areas of the mine amenable to lower cost bulk mining methods. Optimization of mine schedule and equipment utilization should follow.

·	Undertake further studies aimed at upgrading the zinc oxide concentrate to a commercial grade and producing a copper / silver concentrate to maximize potential future revenues. $100,000

Data management and resource modelling

·	Review bulk density measurement methods.

·	Resolve slight discrepancies between drillhole data and wireframes and lack of extrapolation of the MQV wireframe beyond the southernmost drilled section.

·	Restrict rotation of the block model to no more than orientation or use an unrotated model.

·	Estimate antimony, arsenic and mercury in the next resource update, as these metals report to the final concentrates.

·	Model and estimate the percentage oxide component in the MQV mineralization.

·	Review the high grade capping policy.

·	Composite chip samples to equal lengths and decluster the data.

·	The inclusive cost for all modelling is estimated at $50,000.

Mining

·	Undertake currently planned geotechnical drilling program in the summer of 2012 to confirm ground support requirements and stability control during operations. $50,000

·	Incorporate more detail into the dump pocket design for run-of-mine ore. $10,000

·	Prepare a mine dewatering plan to ensure safety at the face during operations. $10,000

·	Review and refine equipment selection to identify if there is any merit in allowing for variations in the size of the drills and scoops (smaller and larger) or if standardization of the equipment size (as is currently planned) optimizes efficiencies.

Environment and social issues:

·	Continue consultation activities with aboriginal groups, government agencies (e.g., Parks Canada) and other interested stakeholders to maintain positive working relationship.

·	Implement environmental studies as required to address information requests from the MVLWB as per its Directive and Work Plan received on 11 May 2012.

EXPLORATION ACTIVITY

The Company has been involved with semi-continuous exploration activity across the Property since 1992. Limited exploration drilling had been undertaken prior to the Company’s initial involvement with the Project in 1992. Up to November 2011, the Company had completed a total of 261 surface and underground exploration diamond drill holes totaling 68,744 metres of coring.

The main focus of exploration and underground development work has been on Main Zone mineralization. A deep drilling exploration program was carried out during 2010/11 seasons to test for the northerly extension of the defined resource. This program successfully intercepted what appears to be the same mineralized structure 1.5 kilometres north along plunge of the resource bearing geology.

In 2011, the Company continued the deep drilling program started in 2010 by extending drillhole PC-10-187 to test for extensions of the Mineral Resource at the Prairie Creek Mine, 1.5 kilometres to the south. The deep drilling program in the Casket Creek area, utilizing the HTM-2500 rig totalled 2,513 metres of coring in four holes including wedges and successfully intersected significant vein-type zinc and lead mineralization about 1.6 kilometres north along a projected strike extension of the geological structure that hosts the defined mineral resource at the mine and demonstrated the probable continuation of vein-type mineralization similar to that located within the main zone at the Prairie Creek Mine.

A re-interpretation of the geological model indicated that the main structural target had been intersected by drillhole PC-10-187 above the known rock formations that host the existing resource. As a result of the less competent shaly rock of the Cadillac Formation, the fault zone is weakly developed.

To further test the vertical extent of this newly identified structure, wedge drillhole PC-11-187W2 was drilled as an undercut to the initial hole. This wedge hole successfully intersected the vertical continuation of the fault structure 50 metres below the PC-10-187 intercept. The PC-11-187W2 intercept was wider, at 3.5 metres, and assayed higher for zinc, at 11.47% Zn. However, this intersection is stratigraphically located well above the primary host rock units found at the mine. Calculated assays based on lab analysis as follows:

11. 2011 Exploration Program: Deep Drill Program
12. Drillhole	13. From (m)	14.To (m)	15.Interval (m)	16. Pb (%)	17. Zn (%)	18.Ag (g/t)	19.Cu (%)
20. PC-10-187	21. 1348.36	22.1348.88	23.0.52	24. 4.92	25. 5.90	26.34	27.0.034
28. PC-11-187W2	29. 1384.00	30.1387.50	31.3.50	32. 5.26	33. 11.47	34.84	35.0.176

The drill intercepts are approximately 100 metres west of the fold axis of the main regional antiform in an identical structural setting to that of the defined vein resource in the main mine zone.

With the continued success at intersecting the target structure, which shows increasing intensity with depth, a subsequent hole, drillhole PC-11-206, was designed to further undercut the intersected structure by 250 metres within the primary host geological formations as found at the mine. This hole had reached a depth of 1,365 metres, approximately 230 metres short of target, at the end of October 2011 when the onset of the winter season forced suspension of the 2011 drilling program. It is planned to complete drillhole PC-11-206 in the 2012 drilling season.

The Company also undertook a summer 2011 diamond drill program at Prairie Creek Mine property to test for additional high-grade vein structures and for other, wider stratabound deposits adjacent to the resource. In summary, 26 shallow holes were drilled with the Company’s Longyear rig, achieving 3,125 metres of coring directed at vein and stratabound targets in the immediate mine area. The vein structure was intersected and identified in each completed hole, many of which returned high grade base metal values.

PC-11-188, collared at the minesite, was abandoned due to excessive overburden and hole PC-11-189 reported no significant assays. Drillhole PC-11-190 intersected a new area of stratabound-type mineralization approximately 150 metres below the 870 metre mine level, which is the lowest level of current developed workings at the Prairie Creek Mine.

The vein mineralization at Prairie Creek is hosted within a structural fault zone and this zone was identified in all completed holes. Due to the close proximity to surface, the mineralization was highly weathered and 70–90% oxidized, which inhibited core recovery and grade determination. Actual grades and true thicknesses will only be verified upon and if they are mined.

A series of 25 metre spaced drill holes were targeted in the upper level vein area, close to surface, and above the presently defined vein resource. The vein structure was intersected and. results from the vein drilling are shown below.

Additional drill intersections of vein and stratabound mineralization were reported from drillholes. Drill holes PC-11-197 to PC-11-204 which targeted in the upper level vein area, close to surface and above the presently defined vein resource. The vein structure was intersected and identified in each completed hole.

Most of the assays listed in the table below are length-weighted composites which contain significantly higher grade internal values, such as in PC-11-202 which contained 20.45% Pb, 33.15% Zn, 300 g/t Ag and 0.752% Cu over 0.74 metres of core and PC-11-200A which returned values of 11.86% Pb, 23.77% Zn, 217 g/t Ag and 0.372% Cu over 2.04 metres of core.

Drill holes PC-11-205, 207 and 208 tested an area above a previously defined zone, known as “the stockwork zone”, which contains a series of narrow high grade veins trending at oblique angles to the main vein strike. Holes PC-11-207 and 208 reported wide moderate grade intercepts resulting from compositing a number of narrow veins together. Hole PC-11-205 did not report any significant assays.

Cabo Drilling (Pacific) Corp. was contracted to supply manpower and technical supervision for the 2012 exploration diamond drilling program during which a total of 5,629 metres of drilling was completed utilizing Company owned drills.

The deep-hole diamond drill exploration program at Casket Creek, 1.6 kilometres north of the current mineral resource, utilized the Company’s TM-2500 coring rig. Following encouraging results from this area in 2011, drilling at Casket Creek commenced in May 2012 to search below PC-11-187W2, which intersected 5% Pb and 11% Zn over 3.5 metres. A total of 2,182 metres over two drillholes (with wedging) was completed. Assay results for the 2012 deep drill program are as follows:

277. Hole	278. From (m)	279. To (m)			280. Length (m)*	281.Pb (%)	282.Zn (%)	283.Ag (g/t)	284.Cu (%)

301. Drill intercepts are not true widths			302.	303.	304.	305.	306.	307.	308.

The drill core confirmed stratigraphy and contained a number of significant structural zones that are weakly mineralized and likely correlate with the previous years’ intercept. A third hole, PC-12-213 was halted due to drilling difficulties within a significant fault structure, believed to be the main structural target. After completing this phase of drilling at Casket Creek the drill rig was moved back to the Prairie Creek Mine site for maintenance and winter storage. Further exploration work in this area is being planned for 2013.

Drillhole PC-12-216 returned the highest grades of silver ever reported from a drillhole on the Prairie Creek property with an intercept of 1.3 metres grading 2059 g/t or 60 oz/ton Ag. The same hole also returned a combined grade of 51.3% lead and zinc over a different intercept of 1.0 metre. Many other intercepts returned multi-ounce silver assays with high lead and zinc values, with Hole PC-12-214 reporting double intercepts of 44% and 23% combined lead and zinc, and Hole PC-12-215 also reporting double intercepts of 43% and 16.2% combined lead and zinc Results are now being incorporated into the mine model and assessed for future exploration planning. Significant results are as follows:

The Company’s Longyear #2 drill rig was rehabilitated during 2012 and used for training purposes and drilled one short hole.

A surface geophysical program involving both electromagnetic (EM) and gravity surveys was also completed on a small part of the Prairie Creek property in the proximity of the mine in August 2012. Interpreted results indicate a strong multi-channel EM anomaly, with coincident gravity anomaly, centered over a previously undrilled area immediately west of the existing underground workings. Further analysis of this anomaly is underway.

ENVIRONMENTAL ASSESSMENT AND PERMITTING

Water Licence and Land Use Permit – Underground Development

The Company applied to the Water Board on March 5, 2001 for Type ‘B’ Water Licence and a Land Use Permit (MV2001L2-0003) for underground decline development and metallurgical pilot plant operation planned for the Prairie Creek Mine. The application was distributed to government agencies, First Nations communities and other organizations in order for the Water Board to conduct a preliminary screening as required by Part 5 of the Mackenzie Valley Resource Management Act.

However in April 2001, both the Parks Canada Agency and Pehdzeh Ki First Nation referred the proposal to the Mackenzie Valley Environmental Impact Review Board for Environmental Assessment (“EA”) pursuant to section 126(2) of the MVRMA. The referral to EA occurred prior to the Water Board’s completion of its preliminary screening of the proposed development.

The Environmental Assessment was conducted throughout 2001 and into 2002. The Review Board submitted its Report of Environmental Assessment (“EA Report”) on February 5, 2002 to the Minister of Indian Affairs and Northern Development. On September 3, 2002, the Minister requested that, as per section 130(1)(b)(i) of the MVRMA, the Review Board was to give further consideration to unresolved issues in the EA Report relating to the tailings containment area and water treatment in general.

Following further assessment the Review Board submitted its Reasons for Decision on April 4, 2003, outlining recommended revisions and additions to the recommendations in its February 5, 2002 EA Report. On June 16, 2003, the Minister approved the Reasons for Decision and directed the Water Board to proceed with the licensing process.

On September 10, 2003 the Water Board approved the issue of Water Licence MV2001L2-0003, and the Land Use Permit MV2001C0023 subject to the conditions set out therein. The Water Licence contains the terms and conditions that the Board felt necessary to protect the environment, conserve the water resources of the Prairie Creek watershed and provide appropriate safeguards in respect of the Company’s use of waters and deposit of wastes.

On October 10, 2003, an appeal to the Federal Court was filed by the Nahanni Butte Dene Band, Pehdzeh Ki First Nation and the Dehcho First Nations against the Mackenzie Valley Land and Water Board and the Company seeking Judicial Review of the decision of the Water Board to issue the Water Licence to the Company. The Applicants’ grounds were that the Water Board issued the Water Licence without including certain conditions included in the recommendations of the Review Board and in the Minister’s approval, and that the Water Board failed to provide the Applicants with adequate consultation throughout the Licence process. Subsequently both the Attorney General of Canada, representing the Minister of Indian Affairs and Northern Development and the Canadian Parks and Wilderness Society, represented by the Sierra Legal Defence Fund (now known as Ecojustice), applied to the Federal Court to be joined as Intervenors in this Appeal.

The Judicial Review hearing was heard by the Court in August 2005. The Lawyers representing the First Nations had argued that the Water Board had exceeded its jurisdiction in issuing the Water Licence without including certain conditions on water treatment which had been recommended by the Mackenzie Valley Environmental Impact Review Board and approved by the Minister, and that the Water Board had failed to observe the principles of natural justice.

In December 2005, the Court issued its Judgment directing the Water Board to reissue the Water Licence with the inclusion of additional language which had been agreed between the Company and the Minister of Indian Affairs and Northern Development. On February 6, 2006 the Water Board reissued the Water Licence incorporating the wording as per the Order of the Federal Court of Canada. The Water Licence was valid for a period of five years expiring September 10, 2008.

In September 2008, the Water Board granted a two-year extension to the Company’s Land Use Permit to September 9, 2010 and the Water Licence was renewed for a period of five years to September 9, 2013.

In January 2013, the Water Board approved an amendment and extension to the Company’s existing Class “B” Water Licence, MV2001L2-0003, for the management, treatment and discharge of mine water from the mine site. The Water Licence has now been amended to cover the underground development of the new decline from the existing 870m level, including pumping, treatment and discharge of water inflows using the existing water treatment infrastructure, and placement of waste rock on an existing waste rock pile. The term of the Water Licence has been extended to September 9, 2019.

With the issue of an amended Water Licence, a new Minewater Contingency Plan was submitted for review. An application request to further revise the Water Licence compliance levels to be comparable to the Metal Mining Liquid Effluent Regulations was made in August and approved by the Water Board in January 2013 for a period of one year after which it reverts back to the original licence compliance levels January 23, 2014.

As contemplated in the Water Licence, the following plans were prepared and have been approved by the Water Board: Minewater Treatment Contingency Plan; Effluent Treatment Options Plan; Abandonment and Reclamation Plan. An existing Fuel Spill Contingency Plan was revised and approved. A Probable Maximum Flood calculation was updated and approved, and flood protection structures and the tank farm facility and associated containment structures were inspected and approved.

Water Licence and Land Use Permit – Winter Road

In May 2003, the Company applied to the Water Board for a Land Use Permit for use of the existing Winter Road from the Liard Highway to the Prairie Creek Mine. The Company argued that this application is exempt from the Environmental Assessment process by virtue of Section 157.1 of the Act. The Company’s argument was rejected by the Water Board on June 1, 2004. The Company filed an Appeal to the Supreme Court of the Northwest Territories seeking judicial review of the decision of the Water Board. The Appeal was heard by the Supreme Court in December 2004.

In a written decision dated May 6, 2005 in the case Canadian Zinc Corporation v Mackenzie Valley Land and Water Board (SCNWT S-0001-CV2004) the Supreme Court of the Northwest Territories ruled in favour of the Company that its Winter Road permit application is “grandfathered” and is therefore exempt from the Environmental Assessment process under the Mackenzie Valley Resource Management Act (“MVRMA”).

In its decision the Supreme Court said that the permit sought by Canadian Zinc is related to the operation of the Winter Access Road, a permit in respect of that same undertaking had been issued before 1984, and therefore the exemption provided in Section 157.1 of the MVRMA governs and a Part 5 assessment does not apply.

This application for a Land Use Permit for the road was referred back to the Water Board. In June 2005 the Nahanni Butte Dene Band wrote to the Water Board asserting infringement of Aboriginal rights and inadequate consultation under Section 35 of the Constitution of Canada. The issue was referred to the Department of Indian Affairs and Northern Development which conducted a preliminary assessment and submitted its report to the Water Board in February 2007.

On April 11, 2007 the Water Board approved the issue of Land Use Permit MV2003F0028 for a period of five years to April 10, 2012.

In June 2007, Canadian Zinc applied to the Water Board for a Class B Water Licence (MV2007L8-0026) to rehabilitate a portion of the road in the proximity of the mine site and sought authorization from the Department of Fisheries and Oceans (“DFO”) to carry out the work.

In June 2007, the Dehcho First Nations claimed that the rehabilitation work constituted a significant alteration to the Winter Road project and requested that the application for the water licence for the proposed rehabilitation work be referred for Environmental Assessment. In December 2007, the Water Board ruled that the proposed rehabilitation work did not constitute a significant alteration.

The issuance of these permits was delayed as they were referred to consultation between the Crown and the Nahanni Band. The Company received the quarry permit on February 29, 2008 and the Water Licence on March 20, 2008. The Water Licence is valid for a period of five years expiring March 19, 2013. The authorization from DFO was received on July 15, 2008.

On June 18, 2009, Parks Canada issued Land Use Permit 2009 L02 for a period of three years to April 10, 2012 for the use of that portion of the road within Nahanni National Park Reserve.

In April 2012, the Company met with Parks Canada at a two day technical session in Fort Simpson, NWT, to discuss the applications associated with road access through the Nahanni National Park Reserve. The Nahanni Butte Dene Band and the Dehcho First Nations were represented at the technical session. A partial road application was submitted to Parks Canada in June 2012. Further field information was collected in September 2012 and the required documentation was submitted in November 19th, 2012. Subsequent information was forwarded to Parks Canada February 13, 2013 who are now further deliberating on the application.

In January 2013, the Water Board issued the Company LUP MV2012F007 for the establishment and operation of the winter road that will service an operating Prairie Creek Mine. The Land Use Permit was issued for a period of five years ending in January 2018, and permits the construction, maintenance, operation and use of a portion of the winter road connecting the Prairie Creek Mine to the Liard Highway, situated outside the expanded Nahanni National Park Reserve. This permit allows the outbound transportation of the zinc and lead concentrates to be produced at the mine and the inbound transportation of fuel and other supplies during the actual operation of the Prairie Creek Mine. The road permit also incorporates realignment of the original route which will improve access and further reduce potential environmental impact. Associated with this LUP the MVLWB also issued a Type “B” Water Licence MV2012L1-0005, valid for a period of seven years, to allow the limited use of local water resources and disposal of waste during road construction and operations.

An additional Land Use Permit and Water Licence for operations relating to the access road that connects the Prairie Creek Mine to the Liard Highway through the expanded Nahanni National Park Reserve is required. The Company has applied to and is in advanced discussions with Parks Canada regarding this road related permit and licence.

Land Use Permit – Phase 3 Exploration

In April 2004, Canadian Zinc applied to the Water Board for an amendment to its previously approved Land Use Permit MV2001C0022A allowing a 60 hole mineral exploration program within 1,000 metres of the Prairie Creek Mine site facility. The amendment was submitted in order to obtain permission to drill anywhere on the extensive mineral leases and claims held by Canadian Zinc at the Prairie Creek Property. Following a Preliminary Screening in June 2004, the Water Board referred the proposed development for Environmental Assessment to the Mackenzie Valley Environmental Impact Review Board citing “public concern about the cumulative effects of this project on the South Nahanni Watershed”.

A detailed Environmental Assessment was carried out throughout 2005. Five government agencies, two first nations and one non-governmental organization (Canadian Parks and Wilderness Society (“CPAWS”)) participated in the Environmental Assessment, which continued over a period of about eighteen months. Canadian Zinc submitted a Detailed Development Description dated December 2004. The Review Board issued its Terms of Reference in April 2005 and held scoping sessions (public meetings) during March and April 2005 in the NWT communities of Fort Liard, Fort Simpson and Wrigley, NT. Canadian Zinc submitted its Developer’s Assessment Report in May 2005 and Technical Reports were submitted by the end of August 2005. A Public Hearing was held in Fort Simpson NT, on October 6, 2005.

The Mackenzie Valley Environmental Impact Review Board completed its Report of Environmental Assessment and submitted the Report to the Minister of Indian and Northern Affairs Canada on December 23, 2005.

The Review Board has concluded that, with the implementation of the commitments made by Canadian Zinc and three mitigation measures recommended in the Report, the proposed development is not likely to have a significant adverse impact on the environment or be cause for significant public concern. The Review Board recommended to the Minister that this development proceed to the regulatory phase of approvals.

The Review Board examined the Public Record for evidence of possible significant adverse impact on the environment, for evidence of cumulative effects from the development in combination with other past, present and reasonably foreseeable future developments, and for evidence of public concern.

The Review Board found that significant adverse cumulative impacts on the environment can be prevented with adequate environmental management. The Review Board also found that the proposed development is not likely to be cause for significant public concern as long as all of the Company’s commitments and all of the measures recommended by the Review Board are implemented.

The Review Board concluded that some public concern over cumulative effects on the Nahanni watershed exists but that this concern would be greatly diminished if the public had assurance that the Company’s commitments, and the additional mitigation measures recommended by the Review Board, would be effectively implemented. The Review Board found that there would not be a concern if the public is kept up-to-date about the environmental protection measures Canadian Zinc will be using. “The best way for the public to receive this assurance is through an independent community environmental monitor who reports back to the effected communities.”

“The Review Board is of the view that the full responsibility for monitoring, evaluation and management should not necessarily rest on the Company alone. Expert agencies of government, such as Department of Indian Affairs and Northern Development, Environment Canada, Department of Fisheries and Oceans, and Government of the Northwest Territories, should be involved co-operatively in the design of this comprehensive monitoring program.”

The Review Board noted that incremental development in the Prairie Creek area is likely to continue and is likely to increase rather than decrease in the foreseeable future. There has already been considerable development in the Prairie Creek watershed and development is likely to increase. On the other hand, all present and reasonable foreseeable future developments are by the same developer, are in close proximity, and are operated, if not as one development, in a co-ordinated and overlapping fashion. This provides Canadian Zinc with an opportunity to effectively manage cumulative effects through responsible environmental management of its activities in each of the developments in the area.

The Review Board recommended approval of the proposed development subject to three mitigation measures. The measures are the actions necessary, in the opinion of the Review Board, to prevent or mitigate adverse impacts on the environment. The three measures recommended by the Review Board are:

·	Government and regulatory authorities are to ensure that all drill waste is disposed of in a manner that does not allow any harmful substance to enter surface waters.

·	Canadian Zinc shall take every reasonable effort to employ a local person, selected in consultation with the Dehcho First Nations, as community environmental monitor, who will independently report back to the Dehcho First Nations.

·	Aboriginal Affairs and Northern Development Canada shall ensure that a comprehensive program to monitor cumulative impacts on fish, wildlife, vegetation and water quality is implemented.

In February 2006, the Minister of Indian Affairs and Northern Development, and on behalf of the Responsible Ministers with jurisdiction (Environment and Natural Resources, Government of the Northwest Territories, Fisheries and Oceans, and the Minister of the Environment on behalf of Environment Canada and Parks Canada), approved the report of the Review Board.

In May 2006, the Water Board issued the Land Use Permit for the Phase 3 exploration drill program, which is valid for five years commencing May 11, 2006. The Company recently received a two year extension to this Land Use Permit which now expires May 10, 2013.

The Company is in the process of reapplying for a new drilling Land Use Permit similar to Phase 3 drill program.

Quarrying Permit – Road Rehabilitation

In June 2007, the Company applied to Indian and Northern Affairs Canada for a quarrying permit to obtain rock to be used in the road rehabilitation. The Quarry Permit was issued February 28, 2008 for a period of one year. In July 2012, Parks Canada extended the LUP for the portion of the road that passes through the expanded Nahanni National Park Reserve for an additional term of two years to April 2014. These permits will allow CZN to undertake road rehabilitation work and prepare the road for operational use. These permits allow use of the road for the re-supply and maintenance of the mine, but do not provide for the planned operational use of the road.

Applications for Operating Licence/Permit

The Company's principal focus over the past four years has been to advance the Prairie Creek Property towards obtaining a Class "A" Water Licence and associated Land Use Permits, through the regulatory process established under the Mackenzie Valley Resource Management Act (the "MVRM Act"), that will permit further development and subsequent mine operation and production at the Property.

Environmental Assessment

In June 2008, the Company applied to the Mackenzie Valley Land and Water Board for a Water Licence and associated Land Use Permits to support a mining operation at Prairie Creek. In August 2008, the application was referred to EA under the Mackenzie Valley Environmental Impact Review Board (the "Review Board"), the primary authority responsible for all environmental assessment and review throughout the Mackenzie Valley in the Northwest Territories, and has since been working through the various stages within the EA. These stages included a Written Hearing on the terms of reference, scoping sessions, submittal of a Developers Assessment Report, two formal Information Requests and two Technical Sessions, a Community Hearing and a two-day Public Hearing, followed by Closing Submissions.

On December 8, 2011, the Review Board issued its Report of Environmental Assessment and Reasons for Decision for the Company’s proposed Prairie Creek Mine (the "EA Report") and submitted the EA Report and Decision to the Federal Minister of Aboriginal Affairs and Northern Development Canada. The Review Board concluded that the proposed development of the Prairie Creek Mine, including the list of commitments made by the Company during the proceedings, is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern. The Review Board therefore concluded that an environmental impact review of this proposed development is not necessary and that the Prairie Creek Mine project should proceed to the regulatory phase for approvals.

The Review Board found that there is broad support among Aboriginal organizations and communities in the Dehcho Region for the benefits that the Prairie Creek Mine could bring to the Dehcho Region of the Northwest Territories. The Review Board acknowledged the commitments that the Company has made toward mitigating potentially adverse social impacts of the project on First Nations and communities in the region.

The Socio-Economic Agreement between the Company and the GNWT is a key document in the Review Board’s findings on impacts of the project on the human environment. In the Review Board’s view, the Prairie Creek Mine is not likely to have significant adverse impacts on the human environment of the Dehcho Region or the Northwest Territories provided the developer’s commitments are followed and enforced and the Socio-Economic Agreement is implemented.

To achieve its proposed water quality objectives, the Company made commitments to enhance its water treatment plant, increase water storage capacity and construct an improved mine effluent outfall for discharge into Prairie Creek. The Company and the Department of Aboriginal Affairs Canada and Northern Development proposed differing approaches to site specific water quality objectives for Prairie Creek. The Review Board is of the view that the implementation of either approach to site specific water quality objectives is not likely to significantly impact water quality in Prairie Creek in the area of the mine site, in Prairie Creek at the Nahanni National Park Reserve boundary, or in Prairie Creek at its confluence with the South Nahanni River. The Review Board noted that the Water Board will decide in the regulatory phase the limits to protect water quality that are appropriate for this Project and setting.

The Review Board provided three suggestions that would improve the monitoring and management of potential impacts from the development of the Prairie Creek Mine:

·	The Review Board noted that construction of a second water storage pond may address a broader range of risks and result in better water management on site and improved water quality in Prairie Creek. The Review Board suggested that the Water Board consider this during the licensing phase.

In the Review Board’s opinion, the Company’s approach to tailings management by placing all tailings underground as tailings paste backfill by the end of mine operations can be achieved and will reduce impacts on water quality so that they are not likely to be significant. The Review Board suggested that the Company prepare a Tailings Management Plan for both the permanent storage of tailings underground and the temporary storage of tailings on surface at the mine site. The Review Board suggests that this Plan should be part of the water licences.

·	The Review Board suggested that the Company use secondary containment of concentrate during transport along the winter road to reduce the risk of contaminant dispersal.

Throughout the EA process, Canadian Zinc proposed certain design modifications to the mine site and access road to improve the project and minimize potentially adverse impacts to the environment. Key design modifications included commitments to increase water storage capacity at the mine site, an improved mine effluent design, an enhanced water treatment plant and realignments of the access road.

The EA Report stated that the Review Board based its decision on the assumption that Canadian Zinc would fulfill its commitments made during the proceedings and that these commitments were important for the Review Board's decision on the significance of adverse impacts. The Review Board stated that, in its opinion, it is therefore important that the Company, appropriate regulatory authorities and government agencies ensure that Canadian Zinc fulfills its commitments. The full list of commitments made by Canadian Zinc is set out in Appendix B to the EA Report. Investors are urged to read and consider closely the full text of the Report of Environmental Assessment and Reasons for Decision, including the list of commitments in Appendix A thereof.

The full text of the Report of Environmental Assessment and Reasons for Decision, together with all proceedings, transcripts, technical reports and detailed information on the EA (EA0809-002) of the Prairie Creek Mine and letters commenting on the EA Report are available on the website registry of the Review Board at http://www.reviewboard.ca/registry/, under the file of Canadian Zinc Corporation, and is included as a schedule to the amended material change report of the Company dated December 22, 2011 and filed on SEDAR on December 22, 2011 in respect of the announcement that the Mackenzie Valley Environmental Impact Review Board has approved the proposed operation of the Company's Prairie Creek Mine.

The Review Board concluded that the proposed development of the Prairie Creek Mine is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern.

The Review Board concluded that the development (including the commitments made by Canadian Zinc) is not likely to have significant adverse impacts on the environment, and that the commitments were already a part of the development, and concluded that no mitigation measures were necessary to ensure that there would be no adverse effects on the environment. Section 128(1) (b) of the Act allows for the imposition of mitigation measures did not apply, because of the conclusion that the development is not likely to have adverse impacts.

The Review Board therefore concluded that an environmental impact review of this proposed development is not necessary and that the Prairie Creek Mine project should proceed to the regulatory phase for approval. The MVRM Act provides that the Minister may order an environmental impact review of the proposal, notwithstanding the Review Board’s determination.

Regulatory Process

In January 2012, following the completion of the Environmental Assessment in December 2011, the Water Board commenced the regulatory process for the issue of a Class “A” Water Licence and Land Use Permits for the operation of the Prairie Creek Mine. In February 2012, the Company submitted a CPD, highlighting the changes that resulted from commitments made by Canadian Zinc during the environmental assessment process.

Formal written interventions to the MVLWB were submitted by the Intervening Parties on January 11, 2013 and CZN submitted a response to the Interventions on January 18, 2013. Beginning on January 29, 2013, the Company and Intervenors attended Public Hearings held in Fort Simpson. The three day session was adjudicated by the Water Board. A Public Hearing scheduled to be held in Nahanni Butte February 1, 2013 was postponed due to weather and held as a Teleconference on February 8, 2013. Final closing statements by all Intervenors were filed by February 15, 2013 and the Company filed its’ closing statement February 22, 2013.

On March 15, 2013 the Water Board issued a Draft Type “A” Water Licence and two Draft Type “A” Land Use Permits for the operation of the Prairie Creek Mine. The Water Licence will entitle Canadian Zinc to conduct mining, milling and associated activities at the Prairie Creek Mine Site, dewater the underground mine for the purpose of mining, use water for processing and domestic purposes, and to dispose of waste for mining and milling, and backfill paste tailings and waste rock into the underground mine. The Land Use Permits will authorize construction and other activities on the Prairie Creek Mine site and on the winter road Transfer Facility near the Liard highway.

Documentation related to this regulatory process is posted on the Water Board website at www.mvlwb.ca/mv/registry.aspx (Year 2008, Canadian Zinc MV2008L2-0002).

ENVIRONMENTAL MATTERS

Permit Delays

The Company has to date experienced long delays in obtaining permits. It is uncertain how long the permitting stage with the Water Board may take or when the Water Licence and Land Use Permits will be issued. Since 2001, the Company has successfully obtained multiple permits for the exploration and development of the Prairie Creek property, including two Type "B" Water Licences, four Land Use permits for exploration activities and underground development and a winter road permit. Various aspects of the Prairie Creek Project have been the subject of six EAs carried out by the Review Board, all of which resulted in recommendations that the relevant project be allowed to proceed. The Company has, to date, successfully carried out extensive programs at Prairie Creek, in accordance with all regulatory requirements and in compliance with all permits and licences.

Given the open-ended nature of the Mackenzie Valley permitting process, the Company cannot, with any reasonable assurance at this point in time, provide a detailed estimate as to the likely costs of permitting activities in 2013.

When the Company receives its operating permits, which is not a certain event, additional financing will be required to bring the mine into commercial production. This will be very dependent on future market conditions, especially with regard to commodity prices, which may impact the Company’s ability to complete development of Prairie Creek. The Company engaged SNC-Lavalin to evaluate the cost of the future development required at Prairie Creek and the Company currently estimates that over $200 million will be required. This number, however, is highly uncertain and could materially change based on final project design, permitting conditions and economic circumstances and conditions at that time.

Impact Assessment

The Developer’s Assessment Report submitted to the Review Board in March 2010 outlines the Company’s assessment of any Potential Environmental Impact that operating the Prairie Creek mine may have on the region as follows:

Human Environment: The Prairie Creek Mine is a relatively modest project that is proposed for a region of the Northwest Territories that has limited other confirmed economic prospects. The real economic and social impact of this project will be generated through the participation of local labour and business in the area, including the communities of Nahanni Butte, Fort Simpson and Fort Liard. Participation will come in the form of direct employment, direct supply of goods and services, and spin-off activities. There will be a period of adjustment as people and communities integrate into the wage economy. The rise in financial wealth and all that it affords will more than offset this initial adjustment period. For those living in the project area, an operating Prairie Creek Mine offers an opportunity for a generation of employment, and will result in a population that is better educated, better trained and better able to cope with, adapt to and capture new opportunities in the future.

Access road operations are expected to increase traditional land use in the area since a re-aligned access road will afford easier access to hunting areas and trap lines. However, a cooperative effort is required to control road access because unauthorized use poses risks to safety and to wildlife from hunting pressures.

Water Quality: Recent studies show that the historical discharge of untreated mine drainage has had no significant impact on downstream water and stream sediment quality, or aquatic life. This suggests Prairie Creek is not particularly sensitive to discharges from the Mine. Nevertheless, Canadian Zinc’s water management strategy for operations will minimize the potential for impacts.

Predictions show that the planned discharge from the Mine during operations will not cause metal concentrations in Prairie Creek to exceed the targets when creek flows are in the normal range year round. Canadian Zinc will monitor flows in the creek, and if flows are found to be lower than normal, the discharge will be temporarily adjusted so that the targets are not exceeded. This will mean no impacts on Prairie Creek water at the Mine, or 7 kilometres downstream at the new Nahanni National Park Reserve boundary.

After mine closure, there will be no drainage from mine portals because the Mine and access tunnels will be completely filled. However, bedrock surrounding the Mine workings is expected to allow the passage of groundwater. This water will contain metals, mostly from mineralization considered uneconomic and not mined, and to a lesser extent from the backfilled waste mixture. A small quantity of seepage from the covered Waste Rock Pile is also possible.

It is believed that the natural zinc concentrations that existed in Prairie Creek before any mine development potentially exceeded the water quality target during winter months when creek flows were lower than normal.

Predictions for Prairie Creek after mine closure suggest all metal concentrations will remain within the water quality targets when creek flows are in the normal range year round, but if creek flows are lower than monthly in winter, zinc concentrations could be similar to those predicted to have potentially occurred before mine development. Post-mine predictions also indicate higher cadmium concentrations in winter if creek flows are unusually low. However, cadmium is not stable in the natural environment and disappears quickly because of various natural reactions. Therefore, the target for this metal is unlikely to be exceeded. As such, it is likely that no additional impacts on water quality will occur after mine closure compared to pre-mine conditions.

Following Technical Sessions held during October 2010 related to the Prairie Creek Environmental Assessment the Mackenzie Valley Review Board issued a Second Round of Information Requests and the Company received 54 Information Requests from seven agencies. The majority of requests related to further details of the proposed operating mine water quality and management.

In order to adequately address the Information Requests the Company needed to generate water products that would be representative of the proposed Prairie Creek operations. This required the collection of local Prairie Creek Mine site source water products and included the collection of a 285 kg bulk mineralization composite rock sample from various underground headings, over 200 litres of minewater and water directly from Prairie Creek itself. SGS Canada Inc., of Vancouver completed a Locked Cycle Test utilizing the collected rock and water samples in a laboratory bench scale study. The mill process flow sheet used in the Locked Cycle Test had been previously determined through numerous metallurgical studies. Both concentrates and waste products, including tailings and water, were generated from this laboratory scale milling process.

SGS-CEMI labs completed further primary treatment tests on both the process water and minewater. Further analysis related to effluent discharge of the proposed Prairie Creek Mine were completed by Hatfield Consultants of Vancouver. These included development of proposed site-specific water quality objectives, definition of an internal dilution zone and development of proposed Effluent Quality Criteria. Additional toxicity studies were completed, on the product effluent using both fish and organic growth to determine discharge toxicity levels and impact assessment related to aquatic sensitivities. These studies resulted in developing a more detailed water treatment scheme and water management system for the proposed Prairie Creek site.

The original proposal to use an end of pipe-type design to disperse mine effluent did not produce satisfactory mixing condition within the Prairie Creek dilution zone. Additional investigation of outfall effluent discharge design by Northwest Hydraulic Consultants was completed and a new exfiltration trench has been proposed and at the outfall location into Prairie Creek. In addition a downstream mixing analysis of the outfall water with Prairie Creek flows was also completed with the use of proprietary HEC-RAS hydraulic modeling software.

Canadian Zinc and the Department of Aboriginal Affairs and Northern Development proposed differing approaches to site specific water quality objectives for Prairie Creek.

The ‘Reference Condition Approach’ (RCA), recommend by AANDC, is a method of determining site specific water quality objectives (SSWQOs) for the environment, which are in turn used to create effluent quality criteria (EQCs) that are meant to regulate end-of-pipe water discharge into the environment.

Canadian Zinc believes that technical solutions acceptable to all parties had been identified for most issues raised in the EA. However, there remained a difference in approach between the Company and AANDC regarding the methodology used to select site specific water quality objectives relating to the treated water discharge from the Prairie Creek Mine. CZN and AANDC agreed to collaborate to move forward in a timely manner to further discuss the issues and seek to reach a mutually acceptable solution and approach. In a letter issued July 15, 2011, the Review Board encouraged the parties to complete the meetings and report preparation prior to the deadline established for final submissions.

During August and September the Company met numerous times with interested parties to further collaborate on water quality objectives. A number of additional components, including enhanced water storage and treatment, were suggested to further add to site contingency factors. Progress was made in resolving certain issues in order to move forward with the broad development of a framework for selecting Site-Specific Water Quality Objectives prior to the filing of Final Submissions by the parties and by the Company on September 16, 2011.

To achieve its proposed water quality objectives, Canadian Zinc made commitments to enhance its water treatment plant, increase water storage capacity and construct an improved mine effluent outfall for discharge into Prairie Creek.

The Review Board addressed the issue of the Reference Condition Approach in its EA Report under a section entitled “3.1.3 Site specific water quality objectives”. The Review Board reviewed the submissions from all parties regarding the differing approaches to establishing SSWQOs.

The Review Board is of the view that the implementation of either approach to site specific water quality objectives is not likely to significantly impact water quality in Prairie Creek in the area of the mine site, in Prairie Creek at the Nahanni National Park Reserve boundary or in Prairie Creek at its confluence with the South Nahanni River.

The Review Board concluded that either approach to SSWQOs would produce a result that was not likely to have any significant adverse impacts on the environment. The Review Board specifically left the issue of what SSWQOs would be used to establish EQCs to the Mackenzie Valley Land and Water Board, stating at page 30, “The Review Board will not provide a recommendation on effluent quality criteria because it is the responsibility of the Mackenzie Valley Land and Water Board.” The Review Board recognizes that the Mackenzie Valley Land and Water Board will decide the limits to protect water quality that are appropriate for this project and setting. The Review Board left the question of determining the appropriate SSWQOs to the Water Board, which will have the responsibility to establish EQC’s in the regulatory phase. The Review Board noted that the Water Board will decide in the regulatory phase the limits to protect water quality that are appropriate for this Project and setting.

The Review Board provided a suggestion to improve the monitoring and management of potential impacts from the development of the Prairie Creek Mine. It noted that construction of a second water storage pond may address a broader range of risks and result in better water management on site and improved water quality in Prairie Creek. The Review Board suggested that the Water Board consider this during the licensing phase.The main purpose of a Water Licence is to regulate the discharge of water to the environment via the application of licence terms and conditions and the establishment of effluent quality criteria (“EQC”).

CZN has proposed a water management plan that includes real-time flow monitoring of the Prairie Creek stream, and discharge of treated mine water and treated process water according to a ‘load-based’ approach. In this approach, the volume and the blend of discharge (comprised of treated mine water and treated process water) are varied according to the actual flow volumes in the receiving stream. In so doing, site-specific water quality objectives can be met, and there is no significant negative impact on the receiving environment.

CZN has proposed Site Specific Water Quality Objectives (“SSWQO”) that have been derived from studies carried out according to the Framework process presented to the Mackenzie Valley Environmental Impact Review Board prior to the conclusion of the Environmental Assessment (EA0809-002) in 2011 and ecological risk assessments (ERA) filed October 2012 and a recent ERA addendum. CZN’s proposed SSWQO take into account the proposed implementation of the optimal additional water storage option, and the best enhanced process water treatment option.

The SSWQO proposed by CZN are all consistent with the Guidelines adopted by the Canadian Council of Ministers of the Environment (CCME), with many well below (better), a few equal to the Guidelines. In its Report of Environment Assessment and Reason for Decisions, issued in December 2011 the Mackenzie Valley Environmental Impact Review Board noted that use of the CCME Guidelines “has been the most commonly used approach in the regulation of mining effluent in the Northwest Territories and Canada and is generally accepted as a highly protective approach.

The Water Board will establish the effluent quality criteria and how the site specific water quality objectives are to be determined and measured, and it is expected that the Land Use Permits and Water License, when issued by the Water Board, will include as mandatory conditions (measures) of such permits and licences the water discharge limits, the various commitments made by Canadian Zinc (where appropriate) and the suggestions of the Review Board set out in the EA Report.

Fish: Bull trout and mountain whitefish are found in Prairie Creek near the Mine, however numbers are low. Spawning trout have been found in Funeral Creek, a tributary of Prairie Creek upstream of the Mine. No evidence of spawning has been found downstream of the Mine. Based on the water quality predictions, mine operations should have no impact on fish. Water quality after Mine closure may cause limited impacts in the immediate vicinity of the Mine site when Prairie Creek flows are less than winter normals. These impacts may have occurred naturally before the Mine existed.

Air: New power generators and an incinerator will limit the release of exhaust gases. Humid conditions will naturally control dust. Any impacts will be limited to the Mine area.

Wildlife and Vegetation: Impacts to wildlife from Mine operations are expected to be limited and largely avoidable. Dall’s sheep lamb on high ground in the area in the spring and could be disturbed by air traffic. Flight path management will be adopted. There is a potential for mortality of Dall’s sheep, woodland caribou and wood bison associated with access road use. A wildlife sighting and notification system will be adopted, in addition to the posting of speed limits. Grizzly bear-human encounters are possible at the Mine site and programs to limit any attraction of bears will be implemented, along with training to respond appropriately to bear encounters. No significant impacts on vegetation are expected because of the relatively small areas of disturbance relative to the large areas of vegetation types.

Terrain and Stability: No large-scale landslide features are evident near the Mine and access road, and the risk of major slope failure appears to be small. Small-scale slope failures and mudflows are possible along the access road east of the Mackenzie Mountains, particularly where permafrost might exist in lowland areas. Impacts can be minimized by good drainage and avoiding removal of the vegetation layer during annual road construction. Engineered structures (the Water Storage Pond and Waste Rock Pile) have been designed to be stable during earthquakes. Dykes protecting the site during major floods were designed and built properly. Maintenance repairs have been made to the armour rock on the dykes.

Accidents and Malfunctions: The majority of Mine activities, and all those associated with chemicals, fuel and hazardous material, will take place within a dyke-protected area, isolated from Prairie Creek. Any spills or contamination can be contained on site, and discharge of site water to the environment can be stopped temporarily. The potential for spills or leaks along the access road will be minimized by controlling road use and using industry-standard containers for transport and storage. Winter conditions will assist in the containment of any spills until a response team can complete a clean-up. The bags of concentrate being transported will be frozen, but road bed tests will be made along the route to make sure material is not being lost.

Cumulative Effects: Very little other activity is or will likely be occurring in the area during Mine operations that could cause cumulative effects. If the Mackenzie Gas Pipeline construction occurs during the life of the Mine, there will be significant regional disruption, but this is unlikely to significantly affect the Mine because the pipeline will require short-term skilled labour. Unauthorized use of the access road would raise safety and wildlife concerns. Canadian Zinc is hoping to control access, and will closely monitor road activity.

Monitoring and Reporting: Significant monitoring of operations and the environment will occur during and after the Mine’s life. Canadian Zinc expects individuals from local communities to be involved in this, preferably as employees. Canadian Zinc undertakes to share the monitoring results. Canadian Zinc’s desire is for the current Canadian Zinc-Parks Canada-Dehcho Technical Committee to evolve into a more public, inclusive committee that meets frequently in the region, and is used as a forum to review Mine performance and to discuss and address concerns.

In December 2011, the Review Board concluded, pursuant to paragraph 128 (1) (a) of the Mackenzie Valley Resource Management Act, that the proposed development of the Prairie Creek Mine as described in the Report of Environmental Assessment, including the list of commitments made by Canadian Zinc during the proceedings, is not likely to have any significant adverse impacts on the environment or to be a cause for significant public concern.

Acid Rock Drainage

The mineral resources at the Prairie Creek Mine are hosted in carbonate rocks. The low sulphide values and high excess neutralization potential of the host rocks (and tailings products) indicate that these materials will pose no long term hazard to the environment through sulphide oxidation processes.

Rescan Environmental of Vancouver, B.C. undertook a detailed analysis of the acid generating characteristics of all dominant rock types at the Prairie Creek Mine in 1994. The results indicated an overwhelming dominance of acid neutralizing minerals, with acid neutralizing carbonate minerals exceeding the total capacity to generate acidity by an average factor of almost 200. Initial analysis of flotation tailings generated from metallurgical testwork has indicated a similar excess of neutralization potential. The Company does not anticipate the potential for any acid rock drainage impacts.

Mesh Environmental Inc. (“Mesh”) undertook a follow-up study during 2005/06, with the objectives of significantly expanding Rescan’s 1994 rock sample dataset and incorporating analyses on mineralized rock samples, tailings and concentrates. Sample collection was completed by Mesh at the Mine Site during September 2005. A total 66 samples were included in Mesh’s characterization program.

A total of ten process waste samples, including mill rock, flotation feed, tailings and concentrate samples from tests performed in 2005 were provided by SGS Lakefield Research Limited in Lakefield, Ontario (“SGS Lakefield”, ISO 9001-2000 accredited). So-called mill rock is wall rock dilution that will be separated from mineralized material in the processing plant.

Static laboratory geochemical characterizations were carried out by Mesh, including acid-base accounting (“ABA”), along with: total inorganic carbon and multi-element Inductively Coupled

Plasma (“ICP”) analyses on all samples; and mineralogy, expanded ABA (pyritic sulphur, siderite correction, acid-buffering characterization curves) and grain size analyses on a sub-set of samples. The following conclusions were made:

• all the host rock units are non-potentially acid generating (“non-PAG”), due to generally low amounts of contained sulphur (less than one percent of total sulphur) and the substantial effective buffering capacity provided by reactive carbonates, the latter reflecting the carbonate-rich nature of the host rock material (which conclusion is supported by the behavior of mixed waste rock that has been exposed on surface at the Mine Site for 25 years, which waste rock does not demonstrate acidic pH values and remains classified as non-PAG as a result);

• Main Zone vein- and stratabound-mineralization are classified as potentially acid generating due to an abundance of sulphide mineralization (although Mesh’s kinetic test data to December 2006 suggests that it may take a substantial amount of time for acidity to be generated, due to the significant amount of buffering capacity available from the carbonate host rocks);

• the two mill rock samples produced as by-products from Main Zone vein mineralization and overbreak are non-PAG and contain relatively low sulphur values (approximately 0.3 percent, or less);

• the final composite tailings samples are classified as non-PAG and contain sufficient buffering capacity to maintain neutral conditions under laboratory conditions;

• tailings supernatant is alkaline (pH 10.7 to 10.9), with total solids in solution (“TSS”) of five to 500 milligrams and relatively high sulphate concentrations of 170 to 230 milligrams per litre, respectively, over the two hour test period;

• sulphide concentrates are classified as potentially acid generating due to slightly elevated pyritic sulphur content and very little neutralization capacity;

• as a result of substantially higher neutralization potential, oxide concentrates are classified as non-PAG (oxide zinc concentrate) and as having uncertain acid generation potential (oxide lead concentrate).

Hazardous Materials

Hazardous and toxic waste materials have been stored at the Prairie Creek Mine site, including sodium cyanide and PCB’s that remained from Cadillac’s operations in the early 1980s. Diesel fuel is also stored on site. All such substances were stored in a secured manner and are regularly inspected by government agencies.

A disposal project for the cyanide and PCB’s commenced in 2007 which involved repackaging the materials such that they are ready for removal from the site for ultimate disposal. This program contracted professional toxic waste specialists to repack the new containers which were stored under tarpaulins on the approved chemical storage pad. In July 2008, following receipt of the necessary regulatory approvals, an airlift of the repacked sodium cyanide drums and associated repackaging waste took place utilizing a DHC-5 rear loading Buffalo aircraft, which shuttled the material from the Prairie Creek mine site to Fort Simpson. From Fort Simpson, Hazco Environmental Services Ltd. transported the cyanide by truck to Cyanide Destruct Systems in Barrie, Ontario and the repackaging waste was removed to Earth Tech’s Swan Hills Treatment Centre in Alberta for destruction and disposal.

In 2010, a program was undertaken to remove, by airlift, all PCB (polychlorinated biphenyls) contaminated material that has been stored in a dedicated safe facility on site since 1982. The Company contracted Hazco Environmental Services to repackage, remove and transport the PCB material off-site to be disposed of, by incineration, at the certified Earth Tech Swan Hills disposal facilities in Northern Alberta.

Endangered Species

The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. Under the Species at Risk Act (S.C. 2002, c.29) (SARA), the federal competent ministers are responsible for the preparation of recovery strategies for listed Extirpated, Endangered, and Threatened species.

The Committee on the Status of Endangered Wildlife in Canada (“COSEWIC”) lists only two species in the area of the Prairie Creek Mine: the Grizzly Bear (Ursus arctos) and the Wolverine (Gulo gulo), both of which are listed in the Special Concern category. In areas removed from the minesite, COSEWIC lists the Peregrine Falcon (Falco peregrinus anatum), the Woodland Caribou, Boreal population (Rangifer tarandus caribou) and the Wood Bison (Bison bison athabascae), each of which are considered threatened. No rare or highly valued species of vegetation or plant communities have been identified in the area. COSEWIC does not list any plant species as endangered, threatened or of special concern in the area of the Prairie Creek Mine.

Detailed field studies of wildlife populations and wildlife habitat in the area of the Prairie Creek Mine and the access road were conducted by Beak Consultants Inc. in 1980-81 and again by Rescan in 1994. None of the listed species and no critical habitats, such as denning or nesting areas, were identified in the area of the Mine. Grizzly bears and wolverines have been observed or encountered only very infrequently in the area surrounding the mine over the past 20 years.

Specific surveys of potential Peregrine falcon nesting habitat have identified no nesting sites in the area of the minesite.

Wood bison were re-introduced into the Nahanni Butte area, 90 kilometres to the southeast of the Prairie Creek Mine, in 1980 with additions to the herd made in 1989 and again in 1998. Potential impacts to these populations are primarily transportation related, in this case primarily in the area of the Liard Highway, and can be mitigated through standard road safety practices.

In 2011, Environment Canada published a proposed recovery strategy on the Boreal population of Woodland Caribou (Rangifer tarandus caribou), referred to as boreal caribou, which were assessed in May 2002 as ‘Threatened’ by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). [Environment Canada. 2011. Recovery Strategy for the Woodland Caribou, Boreal population (Rangifer tarandus caribou) in Canada [Proposed]. Species at Risk Act Recovery Strategy Series.] The long-term recovery goal for boreal caribou is to achieve self-sustaining local populations throughout their distribution in Canada to the extent possible.

Boreal caribou are primarily threatened by a reduction in the availability and suitability of habitat necessary to carry out the life processes necessary for their survival and reproduction. They require large range areas comprised of continuous tracts of undisturbed habitat rich in mature to old-growth coniferous forest, lichens, muskegs, peatlands, and upland or hilly areas. Large range areas with suitable quality habitat allow boreal caribou to disperse across the landscape when conditions are unfavourable (e.g. natural wildfire disturbance, anthropogenic disturbance) and to maintain low population densities throughout the range to reduce the risk of predation. Threats, primarily habitat alteration (i.e. habitat loss, degradation, and fragmentation) from both anthropogenic and natural stressors, and predation have resulted in local population declines throughout their distribution.

Boreal caribou are distributed broadly throughout the boreal forest region, including in the Mackenzie Mountains of the Northwest Territories. In 2010, the Company completed two wildlife surveys with Golder & Associates and Parks Canada, by fixed wing airplane, along the proposed winter road route to the Prairie Creek Mine in order to further assess the wildlife population, with an emphasis on caribou. Caribou populations and potential caribou habitat have been identified in areas removed from the Prairie Creek Mine to the north and east in the Mackenzie Mountains. Potential impacts to these populations are primarily transportation related and can be mitigated through standard road safety practices.

Nahanni National Park Reserve / Parks Canada Memorandum of Understanding

The South Nahanni River is highly valued as a wilderness recreation river and is used for canoeing trips during the summer months. These wilderness adventure tours are supported by a number of outfitting companies from as far away as Ontario.

The Nahanni National Park Reserve was created in 1972, following a canoe trip down the river by then Prime Minister Pierre Elliot Trudeau, specifically for the purpose of setting aside the South Nahanni River for wilderness recreational purposes. Exploration activity at Prairie Creek had been ongoing for many years prior to 1972 and underground development was well advanced at that point in time.

Parliament formally established Nahanni National Park Reserve of Canada in 1972, legally protecting it as Canada’s 26th National Park under the Canada National Parks Act. It was established as a National Park Reserve in view of the fact that there were outstanding land claims in the area. It will only become a fully-fledged National Park once an agreement has been reached with the Dehcho First Nations.

Nahanni National Park Reserve is considered to be of global significance. In 1978, it was the first area added by UNESCO to its list of World Heritage Sites. There are only 13 sites in Canada designated as World Heritage Sites, eight of them being National Parks. Nahanni received this designation because of the geological processes and natural phenomena in the area. In UNESCO’s view, Nahanni is special because it is an unexploited natural area. The presence in this area of three river canyons cutting at right angles to the mountain ranges, with walls of up to 1,000 metres high, Virginia Falls which falls over 90 metres, hot springs, sink holes and karst topography are considered a special combination.

In considering and approving the nomination of Nahanni National Park Reserve for World Heritage Status, the World Heritage Committee stated that “it would be desirable to incorporate the entire upstream watershed in the World Heritage Site.” In 1977, the Minister responsible for Parks Canada directed Parks Canada to examine the possibility of expanding Nahanni National Park Reserve to include more of the head waters of the South Nahanni and the karst terrain. Several studies were conducted to assess this potential.

In June 2009, new legislation was enacted by the Canadian Parliament entitled “An Act to amend the Canada National Parks Act to enlarge Nahanni National Park Reserve of Canada” to provide for the expansion of Nahanni National Park Reserve. Nahanni National Park Reserve was expanded by 30,000 km2, making it the third largest National Park in Canada. The enlarged Park covers most of the South Nahanni River watershed and completely encircles the Prairie Creek Mine. However, the Mine itself and a large surrounding area of approximately 300 km2 are specifically excluded from the Park and are not part of the expanded Park.

The exclusion of the Prairie Creek Mine from the Nahanni National Park Reserve expansion area has brought clarity to the land use policy objectives for the region and will facilitate various aspects of the environmental assessment process. The Government’s decision on the expansion of Nahanni National Park reflects a balanced approach to development and to conservation which allows for mineral resource and energy development in the Northwest Territories and at the same time protects the environment.

Section 7(1) of the new Act amended the Canada National Parks Act to enable the Minister of the Environment to enter into leases or licences of occupation of, and easements over, public lands situated in the expansion area for the purposes of a mining access road leading to the Prairie Creek Area, including the sites of storage and other facilities connected with that road. Heretofore, an access road to a mine through a National Park was not permitted under the Canada National Parks Act, and the Act was amended solely for Nahanni National Park Reserve and specifically for the purpose of providing access to the Prairie Creek Area.

On July 29, 2008, Parks Canada Agency (“Parks Canada”) and Canadian Zinc entered into a MOU with regard to the expansion of the Nahanni National Park Reserve and the development of the Prairie Creek Mine, whereby:

·	Parks Canada and Canadian Zinc agreed to work collaboratively, within their respective areas of responsibility, authority and jurisdiction, to achieve their respective goals of an expanded Nahanni National Park Reserve and an operating Prairie Creek Mine.

Parks Canada recognized and respects the right of Canadian Zinc to develop the Prairie Creek Mine and was to manage the expansion of Nahanni National Park Reserve so that the expansion did not in its own right negatively affect development of, or reasonable access to and from, the Prairie Creek Mine.

·	Canadian Zinc accepted and supported the proposed expansion of the Nahanni National Park Reserve and will manage the development of the Prairie Creek Mine so the mine does not, in its own right, negatively affect the expansion of the Nahanni National Park Reserve.

The 2008 MOU was intended to cover the period up to the development of the Prairie Creek Mine (Phase I). In February 2012, Canadian Zinc and Parks Canada signed a renewed Memorandum of Understanding regarding the operation and development of the Prairie Creek Mine and the management of Nahanni National Park Reserve.

The MOU, which is valid for three years, replaces the previous MOU signed between the Parties in 2008. In the renewed MOU:

·	Parks Canada and Canadian Zinc agree to work collaboratively, within their respective areas of responsibility, authority and jurisdiction, to achieve their respective goals of managing Nahanni National Park Reserve and an operating Prairie Creek Mine.

·	Parks Canada recognizes and respects the right of Canadian Zinc to develop the Prairie Creek Mine and has granted Land Use Permit 2009 – L02 to provide road access through the Park to the Mine area.

Canadian Zinc acknowledges the cooperative management relationship Parks Canada shares with the Dehcho First Nations in the management of Nahanni National Park Reserve. This includes recognition of the 2003 Parks Canada - Dehcho First Nation Interim Park Management Arrangement and the role of the cooperative management mechanism –Nah?a Dehé Consensus Team.

In the MOU Parks Canada and Canadian Zinc (the “Parties”) agreed to make every reasonable effort to address issues of common interest and build a strong working relationship, including convening a Technical Team, including representatives of the Dehcho First Nations, which will better identify, define and consider issues of common interest, including, among other things, development of the access to and from the Prairie Creek Mine through Nahanni National Park Reserve and operation of the Prairie Creek Mine.

The Parties have also agreed to share with one another and the Technical Team any existing technical and scientific information relevant to a discussion and analysis of issues of common interest to the Parties. The parties have agreed to make reasonable efforts to be timely in regards to permit requests being submitted, with ample time for review and consultation, such review and consultation will occur without unreasonable delay.

The MOU is an expression of the mutual intentions of the parties and is not legally binding on them or enforceable against them. The MOU does not create any new powers or duties or alter or affect any rights, powers and duties established by law, including by the Parks Canada Agency Act and the Canada National Parks Act, or result in the Parties relinquishing any right, jurisdiction, power, privilege, prerogative or immunity.

To the extent that the Prairie Creek Mine is subject to regulatory or government processes, including hearings, Parks Canada reserves the right, while recognizing the intent of the MOU, to participate in any such process and take such positions as it sees fit and the MOU does not, and is not intended to constrain Parks Canada from doing so, subject only to the understanding that in doing so Parks Canada will not object to or oppose, in principle, the development of the Prairie Creek Mine.

Environmental Obligations

As at December 31, 2012, the Company has estimated the present value of expenditures required for reclamation and closure costs at the Prairie Creek Property to be approximately $2.961 million ( 2011- $2.445 million) on an undiscounted basis, mostly to be incurred at the end of the life of the mine.

The Company recognizes liabilities for statutory, contractual, constructive or legal obligations, including those associated with the reclamation of exploration and evaluation assets, when those obligations result from the acquisition, construction, development or normal operation of the assets. Initially, a provision for a decommissioning liability is recognized at its present value in the period in which it is incurred, which is generally when an environmental disturbance occurs or a constructive obligation is determined. Upon initial recognition of the liability, a corresponding amount is added to the carrying amount of the related asset and the cost is amortized as an expense over the economic life of the asset using the unit of production method. Following the initial recognition of a decommissioning liability, the carrying amount of the liability is increased for the passage of time and adjusted for changes to the current market-based discount rate and the amount or timing of the underlying cash flows needed to settle the obligation. Changes to estimated future costs are recognized in the statement of financial position by either increasing or decreasing the decommissioning liability and the decommissioning asset.

Various assumptions are used in determining the liability including current mine plans, future retirement costs and estimates of resources. The estimates used require extensive judgment as to the nature, cost and timing of the work to be completed and may change with future changes to cost structures, environmental laws and requirements and remediation practices employed. Management evaluates the decommissioning liability estimates at the end of each reporting period to determine whether the estimates continue to be appropriate. Other than specific environmental matters discussed in this Annual Information Form, the Company is not aware of any material environmental matter requiring significant capital outlays in the immediate future.

FIRST NATIONS

The Prairie Creek Mine is located on land claimed by the Nahanni Butte Dene Band of the Dehcho First Nations (“Dehcho” or “DCFN”) as their traditional territory. The Nahanni Butte (Nahaahdee) First Nation is a “band” pursuant to the Indian Act RSC 1985. The members of the Dehcho First Nations are Aboriginal people within the meaning of Section 35 of the Constitution Act, 1982.

The Dehcho are a distinct group of Aboriginal people, whose ancestors were among the South Slavey people of the Dene Nation of what is now the Northwest Territories, and the Metis people within the DCFN territory. The Dehcho have had their own system of laws, religion, economy, customs, traditions and language since time immemorial. Many Dehcho people continue to rely heavily on the land, water and resources within DCFN territory for sustenance, social and ceremonial purposes.

The DCFN is an organization representing all of the Dene and Metis peoples in the Dehcho territory of the Northwest Territories which comprise thirteen separate communities. The DCFN have incorporated a society under the laws of the Northwest Territories in order to provide leadership, governance, administration and program delivery to their member communities. The DCFN is a governing body of the Dehcho people lands, administers oversees a number of programs and services for its member communities including those relating to health, employment, education, and land and resource management.

The DCFN and their member Aboriginal communities hold collective Aboriginal title and rights and treaty rights to Dehcho territory and hold other Aboriginal rights as a collective in relation to their land and governance over the land and the Dehcho people.

In the Mackenzie Valley, land is owned, or managed, controlled and administered by different governments or landowners. Land can be either Crown or Commissioner’s land administered by land managers, or privately owned.

In the Northwest Territories, private lands are owned largely by First Nations with settled land claims. There are currently three major landowners in the Mackenzie Valley - the Gwich’in, Sahtu and Tlicho. It is anticipated that as claims are settled in the Dehcho region, more private lands will be created and Aboriginal groups will become recognized landowners in their respective regions.

The Federal Government has recognized that the inherent right of self-government is an existing Aboriginal right recognized and affirmed by Section 35 of the Constitution Act, 1982. The Dehcho are engaged in ongoing land settlement negotiations with the Government of Canada and the Government of the Northwest Territories in what is referred to as the “Dehcho Process.” The Federal Government first attempted to negotiate land claim settlements in the Northwest Territories, with the Dene/Metis in the late 1980s without success. Subsequently settlement agreements were reached first with the Gwich’in and Sahtu Dene/Metis people and later with the Tlicho in 2005. The Dehcho have not settled their land claim with the Federal Government. The Dehcho and the Federal Government of Canada both claim legal title to this territory, the Dehcho by virtue of historical occupation and the Federal Government under Treaty 8, signed in 1900, and Treaty 11 signed in 1921 and 1922. The Federal Government and the Dehcho First Nations disagree on the interpretation of Treaties 8 and 11 and legal title to the land remains in dispute. Canada maintains that under the Treaties the Dehcho extinguished ownership of their traditional lands. The Dehcho have threatened to take the Federal Government to court, or to the United Nations, over the key issue of sovereignty. The Dehcho territory has an area of approximately 210,000 km2 and has a native population of approximately 6,000.

Since the mid-1990s the Dehcho and the Federal Government have been engaged in the Dehcho Process whereby the Federal Government and the Government of the Northwest Territories have agreed to negotiate with the Dehcho First Nations on a government to government basis in order to set out land, resources and governance rights to apply in the Dehcho territory. The objective of negotiations is to complete a Dehcho Final Agreement which clarifies and builds upon existing Treaties by implementing a Dehcho government which will make laws and deliver programs and services; be a public government based upon Dehcho First Nations laws and customs and other Canadian laws and customs; and be the primary government for the delivery of programs and services to residents of the Dehcho territory. The Final Agreement will also describe intergovernmental relationships and jurisdictions, provide for certainty and clarity of rights respecting land, resources and governance and provide for the use, management and conservation of land, water and other resources, including wildlife, fish and their habitat in the Dehcho territory.

Early negotiations proved very slow in part because the Dehcho initially rejected the land selection process by which other land claim disputes have been typically settled in the North. Under the typical system, the Federal Government and First Nations select by negotiation particular areas of land in the area under dispute. Once selected the Government makes a financial payment and the claim is settled. However, the Dehcho have been holding out for full constitutional, legal and governmental control over their entire region, where effectively the laws of Canada would no longer apply, and this has led to lengthy and difficult negotiations.

The DCFN’s position is that the Mackenzie Valley Resource Management Act cannot and should not apply within Dehcho territory, that the legislation was enacted without the participation of, or any consultation with, the DCFN and was imposed on the Dehcho territory against DCFN wishes. The DCFN have stated that the Final Agreement must, among other things, include a new resource management regime in Dehcho territory other than the Mackenzie Valley Resource Management Act.

In 2001, the Federal Government and the Dehcho First Nations entered into a Framework Agreement dated May 23, 2001. The Framework Agreement contemplates providing a structure for the negotiation of the Final Agreement. However, all negotiations are without prejudice to the legal position of the parties and nothing in the Framework Agreement is to be interpreted as creating, recognizing or denying rights or obligations of any of the parties. The Federal Government and the Dehcho agreed that it is desirable that the negotiations proceed at a pace which allows for the people of the Dehcho territory, and particularly the Elders, to remain fully informed and involved in the process.

As contemplated in the Framework Agreement, an Interim Measures Agreement, also dated May 23, 2001, was executed between the parties to provide for interim arrangements pending the negotiation and signing of the Dehcho Final Agreement.

Under the Interim Measures Agreement, the Governments and the Dehcho agreed to develop a land use plan for the Dehcho lands outside Nahanni National Park Reserve and for that purpose to establish a Land Use Planning Committee. The purpose of the Land Use Plan is to provide for the conservation, development and utilization of the land, waters and other resources in the Dehcho territory, taking into consideration the principles of respect for the land, as understood and explained by the Dehcho Elders, and sustainable development.

Under the Interim Measures Agreement, Canada and the Dehcho agreed to negotiate for the purpose of identifying lands to be withdrawn from disposal and mineral staking and Canada agreed to withdraw from disposal, by Order in Council under the Territorial Lands Act, the lands identified in this process.

The Interim Measures Agreement specifically provides at sections 19 and 23 that land withdrawn from disposal under the Agreement shall be subject to the continuing exercise of existing rights, titles, interests, entitlements, licences and permits and that the provisions of the Agreement shall not effect access to or across withdrawn lands.

The Agreement also provides that no new water licences or land use permits will be issued under the Mackenzie Valley Resource Management Act within the Dehcho territory except after written notice to the Dehcho First Nations and after a reasonable period of time for the Dehcho to make representations with respect to the application for such licence or permit. Canada also agreed not to issue any new prospecting permits under the Canada Mining Regulations in the Dehcho territory without the support of the affected Dehcho First Nation.

The parties also agreed to enter into negotiations for the purpose of concluding an Interim Resource Development Agreement with the objective of fostering resource development in the Dehcho Territory and to accrue benefits from Canada to the Dehcho First Nations. An Interim Resource Development Agreement was signed on April 17, 2003 under which Canada agreed to provide to the Dehcho First Nations a percentage of Federal resource royalties collected from the Dehcho area of the Mackenzie Valley.

Canada also agreed that the Final Agreement will ensure that a major mining project that requires any authorization from Canada, and that will impact on the Dehcho, shall be subject to negotiation with the Dehcho of an agreement relating to that project. A major mining project is defined as a project related to the development or production of minerals that will employ an average of 50 persons annually for the first five years in the Dehcho territory and for which more than $50 million will be expended in capital costs. The Company believes that the Prairie Creek Project is currently the only such major mining project in the Dehcho territory.

The Interim Measures Agreement also provided that the Dehcho may propose protected areas for land withdrawal or permanent protection under the Northwest Territories Protected Areas Strategy. The parties also agreed to negotiate an interim management arrangement respecting the management of Nahanni National Park Reserve.

The Interim Measures Agreement was made without prejudice to the legal position of the parties and nothing in the Agreement is to be interpreted as creating, recognizing or denying rights or obligations on the part of the parties.

In 2003, Canada and the Dehcho agreed to an interim withdrawal of lands covering an area of approximately 80,000 km2 for a period of five years. The withdrawal was confirmed by Order in Council dated August 13, 2003. The areas of the withdrawn lands do not include the Prairie Creek Mine but include all of the Company’s Mining Lease 2854 and part of Mining Leases 2931, 3314 and 3313. The withdrawn land also includes an area over which part of the Company’s road to the Prairie Creek Property passes. However in accordance with Sections 19 and 23 of the Interim Measures Agreement such withdrawal is subject to the continuing exercise of existing rights, titles, interests, entitlements, licences, permits, reservations, benefits and privileges and does not affect access to or across withdrawn land.

In August 2003, a Memorandum of Understanding respecting the expansion of Nahanni National Park Reserve dated 24 June 2003 was signed between the Dehcho and the Parks Canada Agency, whereby as part of the Dehcho Process, Parks Canada and the Dehcho agreed to work co-operatively towards completion of a feasibility study towards the addition of the identified lands to the Nahanni National Park Reserve and to recommend an amendment to the Canada National Parks Act for a new boundary for the expansion of the Nahanni National Park Reserve and, as part of the Dehcho Final Agreement, moving the Nahanni National Park Reserve to full National Park status under the Canada National Parks Act.

At the same time in August 2003, an Interim Park Management Arrangement for the Nahanni National Park Reserve was signed between the Dehcho and Parks Canada Agency designed to give the Dehcho a greater role in the Park management process. A Consensus Team was established, comprising three appointees of Parks Canada and four from the Dehcho First Nations (two from Nahanni Butte) to address, amongst other things, making recommendations in respect of impacts of land and resource uses in areas outside Nahanni National Park Reserve.

Under the Arrangement the Dehcho and Parks Canada agreed that while the current jurisdiction of Parks Canada is restricted to Nahanni National Park Reserve, the ecological integrity of the Park Reserve depends on the ecological integrity of the South Nahanni River watershed as a whole. The Prairie Creek Mine is located within the watershed of the South Nahanni River.

The Interim Park Management Arrangement is a statement of interests only and is not legally binding. Nothing in the Arrangement obliges Canada to act in a manner inconsistent with federal or territorial legislative or regulatory jurisdictions or authorities and the Nahanni National Park Reserve shall be administered and managed in accordance with the Canada National Parks Act.

During 2005, negotiations on the Dehcho Process broke down because of issues surrounding the proposed Mackenzie Valley gas pipeline. In June 2005 the Dehcho First Nations entered into a Settlement Agreement with Canada [represented by the Minister of Indian Affairs and Northern Development] to settle Court actions which had been commenced by the Dehcho in the Northwest Territories Supreme Court and in the Federal Court against Canada and the Mackenzie Valley Environmental Impact Review Board arising out of disputes concerning the Mackenzie Gas Project. In the Settlement Agreement Canada and the Dehcho agreed to resolve issues related to the participation of the Dehcho in the environmental and regulatory review of the Mackenzie Gas Project and which they agreed to facilitate.

The Settlement Agreement recites that Canada and the Dehcho have differing views as to the existence and scope of the rights of the Dehcho First Nation(s) recognized by Section 35 of the Constitution Act 1982, and the nature and extent of Canada’s requirements to consult with the Dehcho First Nations. In the Settlement Agreement the parties agreed to take all reasonable steps to negotiate the terms of the Dehcho Final Agreement which would include agreement to establish a Dehcho Resource Management Authority (DCRMA) which will be a body of public government. The Final Agreement will describe the legal capacity, structure, accountability, rights, powers, privileges and responsibilities of the DCRMA; source(s) of the DCRMA’s powers, privileges and responsibilities; relationship of the DCRMA to the Mackenzie Valley Resource Management Act, and rules regarding conflict of laws and the priorities of laws. For greater certainty, the Final Agreement may provide for a stand alone DCRMA harmonized with the Mackenzie Valley Resource Management Act. The Settlement Agreement provides that the Final Agreement will provide for the circumstances in which laws within the jurisdiction of the Dehcho First Nations, any successor organization, or any government established pursuant to a Final Agreement, will take priority over the laws of Canada in the event of a conflict. The parties agreed to negotiate a Final Agreement in accordance with the Dehcho First Nations Framework Agreement.

In the Settlement Agreement, the parties agreed to implement a Land Use Plan that is approved by the Dehcho First Nations, approved the Minister of Environment and Natural Resources of the Northwest Territories, and favourably considered by the Minister of Indian and Northern Affairs, Canada, as soon as possible after the Plan’s completion.

In the 2005 Settlement Agreement the parties affirmed the Interim Resource Development Agreement dated April 17, 2003 and agreed to take immediate steps to establish a working group comprised of the parties to the Dehcho First Nations Interim Measures Agreement for the purposes of ensuring that the issues arising from the implementation of the Resource Development Agreement are addressed in a timely manner. The parties also agreed that once an Agreement in Principle is ratified, the resource royalty sharing formula set out in the Interim Resource Development Agreement will be replaced with any Resource Revenue Sharing Formula agreed to in the Agreement in Principle.

The Settlement Agreement further provides that, except for certain specified articles of the Agreement, the Settlement Agreement is not legally binding and is intended as an expression of goodwill and as a political commitment.

Negotiations under the Dehcho Process continued during 2006 with Canada presenting a formal comprehensive offer of land selection, local governance provisions and financial compensation but this offer was rejected by the Dehcho First Nations. The Dehcho First Nations are insisting on the approval of a Land Use Plan (see below). Negotiations continued intermittently during 2007 through 2009 with no apparent progress reported.

The Dehcho Land Use Planning Committee (the Committee), was formally established in February 2002 under the authority of the Dehcho Interim Measures Agreement with the responsibility to prepare a land use plan for the Dehcho territory. The land use planning process is a community driven process where the goals and values of the residents of the Dehcho guide the development of the Plan. The Committee works closely with other planning partners such as governments, public agencies, non-government organizations and businesses to fulfill its mandate.

Land use planning boards are responsible for preparing comprehensive land use plans for their respective settlement areas. These plans guide the use of Crown, settlement, and other private lands and provide direction for the conservation, development and use of land, waters and other resources. Essentially, the land use planning boards create plans which lay out the permitted and prohibited uses of all land within a settlement area. They develop land use plans for their regions and recommend approvals, exceptions and amendments to related plans.

A Land Use Plan is a public document that sets aside different areas for different uses, and describes what activities are permitted or not permitted in specified areas. The land use plan applies to both Crown and settlement lands. It does not apply to lands within municipal boundaries or lands within national parks or historic sites.

Once the land use planning board has adopted a Land Use Plan, it must submit the plan to the First Nation of the settlement area, the Territorial Minister and the Federal Minister for approval.

The mission statement of the Dehcho Land Use Planning Committee is to develop a land use plan as a management tool to determine what type of land use activities should occur and where they should take place. The plan will balance economic, social, environmental and cultural needs and interests. The plan will be guided by the principals of sustainable development and respect for the land as understood and explained by the Dehcho Elders. The planning area excludes municipal areas and Nahanni National Park Reserve.

The purpose of the Land Use Plan is to promote the social, environmental, cultural and economic well-being of residents and communities in the Dehcho territory, having regard to the interests of all Canadians. The Plan shall provide for the conservation, development and utilization of the land, waters and other resources in the Dehcho territory.

The Dehcho Land Use Planning Committee includes representatives of the Dehcho First Nations, the Government of the Northwest Territories and Government of Canada. As outlined under the Dehcho Interim Measures Agreement the DCFN appointed two members while the two Governments each appointed one member. Upon the recommendation of the Committee, the parties to the Interim Measures Agreement appoint a fifth member as Chairperson.

Once approved, the Land Use Plan will provide legally binding direction to regulatory agencies and decision-makers in their assessment of development projects, protected areas proposals and other land uses.

The Land Use planning process considered the traditional use and occupancy information that was gathered to determine the Interim Land Withdrawals, along with other information on the natural resources and the economic and social needs of the communities. In turn, the Plan will guide the revision of the Interim Land Withdrawals based on the new information that has been gathered. Representatives of the Planning Committee visited the Prairie Creek Mine site in September 2004.

The Company made a detailed submission to the Dehcho Land Use Planning Committee and participated in the planning process. The Company commented on each draft of the Plan as such draft was produced and participated in various Public Forums. The Company had concerns about the latest draft of the Land Use Plan (November 2005 – Revised February 2006) and recommended that the draft in its current form not be approved. The Department of Indian Affairs and Northern Development has also expressed concern to the Committee (January 2006).

The draft Land Use Plan was approved by the General Assembly of the Dehcho First Nations in May 2006 and submitted to the Minister for consideration. The Minister did not accept the Plan arguing that it incorporated too much land to be preserved from development. In April 2007 the Federal Government and the Dehcho First Nations entered into an agreement to form a new Committee with representatives from all sides to negotiate a new revised plan. The Company understands that negotiations on a draft Land Use Plan are continuing.

The outcome of the Dehcho Process negotiations is expected to be a Final Agreement that will provide, amongst other things, for the implementation of a Dehcho government within the Dehcho territory. It is expected that the negotiations towards a Dehcho Final Agreement will take many years to complete.

The Company cannot predict the impact, if any, that the Dehcho Final Agreement if eventually approved and signed may have on the Prairie Creek Mine or the permitting thereof.

Nahanni Butte Dene Band

The Prairie Creek Mine is located 90 kilometres from the nearest settled community of Nahanni Butte, located at the confluence of the South Nahanni and Liard Rivers, 146 kilometres downstream of the minesite. The population of Nahanni Butte is approximately 90 people and water for domestic purposes is supplied by well. There is no permanent road access into the Prairie Creek Property, other than the existing Winter Road which was established in 1981. Regular access is by air only to a private airstrip controlled by the Company. There is no other existing land occupation, nor commercial land or water based activities in the vicinity of the mine. Similarly, no traditional use or trapping activity has been observed in the minesite area in recent history.

In October 2008, Canadian Zinc and the Nahanni Butte Dene Band entered into a MOU, to establish a mutually beneficial, co-operative and productive relationship. In the MOU, the Band agreed to maintain close communication links with Canadian Zinc, participate in good faith in current and pending environmental assessment and regulatory processes, and not to oppose, “in principle,” mining operations at Prairie Creek. Canadian Zinc has agreed to apply best efforts to employ Band members and to assist the Band and its community to benefit from business opportunities associated with the exploration and development of the Prairie Creek Project. The MOU also provides for the subsequent negotiation of an Impact Benefits Agreement regarding mining operations. Nothing within the MOU is intended to define, create or extinguish any rights of the Band or Canadian Zinc and the MOU is not legally binding on the parties.

The Company continued discussions and engagement with the Band throughout 2009 and 2010, specifically regarding their Traditional Knowledge and alternate routes for the access road to Prairie Creek, taking into consideration the expressed preferences of the community of Nahanni Butte. The Band outlined their concerns with the project and the Company’s responses to date include investigation of road realignment options and surveys of specific locations along the access road for heritage resources.

In January 2011, the Company signed the NAH?A DEHE DENE PRAIRIE CREEK AGREEMENT (the “Nahanni Agreement”) which provides for an ongoing working relationship between Canadian Zinc Corporation and the Nah?a Dehe Dene Band (Nahanni Butte Dene Band) that respects the goals and aspirations of each party and will enable the Nahanni community members to participate in the opportunities and benefits offered by the Prairie Creek Project and confirms their support for the Prairie Creek Mine.

The Nahanni Agreement provides a framework such that training, employment and business contracts are made available to Nahanni to ensure maximization of benefits from opportunities arising from the Prairie Creek Project in a manner that will be to the mutual benefit of both parties.

The Company believes that the separate goals of the Dehcho First Nations in achieving political sovereignty and economic self-sufficiency whilst protecting the environment are compatible. The Nah?a Dehe Dene Prairie Creek Agreement provides for a positive and cooperative working relationship between the Company and Nahanni Butte in respect of developing and operating an environmentally sound mining undertaking at Prairie Creek, which will not have significant adverse environmental effects on the ecological integrity of the South Nahanni River or the Nahanni National Park Reserve.

Liidlii Kue First Nation

In June 2011, the Company signed an Impact Benefits Agreement (“LKFN Agreement”) with the Liidlii Kue First Nation (“LKFN”) of Fort Simpson. The LKFN Agreement is similar in many respects to the above mentioned Nahanni Agreement entered into with the Nahanni Butte Dene Band. The LKFN has agreed to support CZN in obtaining all necessary permits and other regulatory approvals required for the Prairie Creek Mine Project. The Agreement is intended to ensure that CZN undertakes operations in an environmentally sound manner. LKFN will appoint a qualified Monitor to monitor environmental compliance and to monitor impacts of the Mine on the environment or wildlife and to work with CZN to prevent or mitigate such impacts.

The LKFN Agreement provides a framework such that training, employment and business contracts, and some financial provisions are made available to the LKFN to ensure maximization of benefits from opportunities arising from the Prairie Creek Project in a manner that will be to the mutual benefit of all parties. The Liidlii Kue First Nation is a member of the Dehcho First Nations. LKFN is the largest member of the Dehcho First Nations.

SOCIO-ECONOMIC AGREEMENTS

In August 2011, the Company signed a Socio-Economic Agreement with the Government of the Northwest Territories related to the planned development of the Prairie Creek Mine. The Socio-Economic Agreement establishes the methods and procedures by which the Company and the GNWT have agreed to work together to maximize the beneficial opportunities and minimize the negative socio–economic impacts arising from an operating Prairie Creek Mine. The Socio-Economic Agreement defines hiring priorities and employment commitments and practices during the construction, operation and closure of the Prairie Creek Mine and across the entire spectrum of project-based employment. The Company has targeted employment levels of at least 60% Northwest Territories residents and 25% Aboriginals. The Company has agreed to implement policies to maximize business and value-added opportunities for businesses in the Northwest Territories. Canadian Zinc will use its best efforts to ensure that purchases of goods and services through or from Northwest Territories businesses will be at least 30% during construction and at least 60% during operations.

In August 2011, Human Resource and Skills Development Canada, a federal department of the Government of Canada, approved a commitment of more than $3 million over a three-year period to fund "More Than a Silver Lining", a program to provide Aboriginal participants with training-to-employment opportunities in a variety of mining-related occupations at the Prairie Creek Mine. In addition to the funding from the Government of Canada, the program will receive an additional $1 million from Canadian Zinc, the GNWT and the communities of Nahanni Butte, Fort Simpson, Fort Liard, Trout Lake and Jean Marie River.

During 2012, the Company initiated programs which included training for positions such as Office Administration, Mineral Exploration Field Assistant, Environmental Monitors, Heavy Equipment Operators, Diamond Drill Helper, Advance Medical First Responder and Camp Cook. The Silver Lining training program has trained 62 individuals with many of the graduates joining the staff at the Prairie Creek Mine, Canadian Zinc’s Fort Simpson office, or service providers to the Project.

Canadian Zinc plans to use the existing Northwest Territories public transportation system to bring goods, fuel and equipment by road to the Mine and to transport its mineral products from the Mine to world markets. As part of this Collaborative Agreement, to assist in priority setting, CZN will provide reports to the Department of Transportation on its anticipated road transportation requirements for the construction and operation of the Prairie Creek Mine which will help the Department of Transport to plan future work on these roads to maintain and enhance these roads effectively and the Department agreed to work closely with Canadian Zinc to ensure public safety by identifying areas of Highway 7 and the Nahanni Butte access road that require enhancement or upgrading.

POLICIES

The Company maintains a written Code of Ethics (the “Code”), which defines the ethical and regulatory standards applicable to all directors, officer and employees (including contractors) and their family members (the "Representatives") of Canadian Zinc and its subsidiary and affiliates to promote: honest and ethical conduct; avoidance of conflicts of interest, whether actual or potential; full, fair, accurate, timely and understandable disclosure in financial statements, reports and documents that the Company files with, or submits to, shareholders and securities regulators, as well as in other public communications made by the Company; compliance with various legislation and regulations applicable to the Company; prompt internal disclosure of any violation of the Code; and accountability for any failure to respect the Code.

The full text of the Code of Ethics may be viewed at the Company's web site (www.canadianzinc.com)

RISK FACTORS

The following are major risk factors management has identified which relate to the Company’s business activities. Such risk factors could materially affect the Company’s future financial results, and could cause events to differ materially from those described in forward-looking statements relating to the Canadian Zinc. Though the following are major risk factors identified by management, they do not comprise a definitive list of all risk factors related to the Company’s business and operations.

Other specific risk factors are discussed elsewhere in this AIF, as well as in the Company’s consolidated financial statements (under the headings “Nature of Operations and Going Concern”, “Significant Accounting Policies” and “Financial Instruments” and elsewhere within that document) and in management’s discussion and analysis (under the headings “Critical Accounting Estimates” and “Risk Factors” and elsewhere within that document) for its most recently completed financial year, being the year ended December 31, 2012, and its other disclosure documents, all as filed on the SEDAR website at www.sedar.com. Additional risks and uncertainties not currently known to the Company or that the Company currently deems to be immaterial may also impair the Company, and the Company's failure to successfully address any such risks and uncertainties could have a material adverse effect on its business, financial condition and/or results of operations, and the future trading price of its common shares may decline and investors may lose all or part of their investment.

The risk factors outlined in this section and elsewhere in this Annual Information Form should be carefully considered by investors when evaluating an investment in the Company.

Permitting, Environmental and other Regulatory Requirements

The operations of Canadian Zinc require licences and permits from various governmental and regulatory authorities. Canadian Zinc does not hold all necessary licences and permits under applicable laws and regulations for the operation of the Prairie Creek Mine. Canadian Zinc believes that it is presently complying in all material respects with the terms of its current licences and permits. However, such licences and permits are subject to change in various circumstances. There can be no guarantee Canadian Zinc will be able to obtain or maintain all necessary licences and permits as are required to explore and develop its properties, including the Prairie Creek Property, commence construction or operation of mining facilities or properties under exploration or development, or to obtain them within a reasonable time.

The Prairie Creek Project is located in an environmentally sensitive and remote area in the Mackenzie Mountains of the Northwest Territories, within the watershed of the South Nahanni River. The South Nahanni River is considered to be of global significance, is highly valued as a wilderness recreation river and is a designated World Heritage Site. The South Nahanni River flows through the Nahanni National Park Reserve.

The Prairie Creek Property is encircled by the Nahanni National Park Reserve; however, an area of approximately 300 km2 immediately surrounding the Prairie Creek Mine is specifically excluded from the Park. In 2009 new legislation entitled “An Act to Amend the Canada National Parks Act to enlarge Nahanni National Park Reserve of Canada” was enacted, which also authorized the Minister of Environment to enter into leases, licences of occupation or easements over Nahanni Park lands for the purposes of a mining access road leading to the Prairie Creek Mine area, including the sites of storage and other facilities connected with that road. The Company will require permits from the Minister of Environment and/or the Parks Canada Agency for the purposes of accessing the Prairie Creek Mine Area and Parks Canada has granted Land Use Permit 2009 – L02 to provide road access through the Park to the Mine Area. There can be no guarantee the Company will be able to obtain or maintain all necessary permits or to obtain them within a reasonable time or on acceptable terms.

The Company has experienced long delays in obtaining permits to date. The Company anticipates continuing difficulties and delays with its permitting activities and faces ongoing opposition and legal challenges from certain interests.

Canadian Zinc’s activities are subject to extensive federal, provincial, territorial and local laws and regulations governing environmental protection and employee health and safety. Canadian Zinc is required to obtain governmental permits and provide bonding requirements under federal and territorial water and mine regulations. All phases of Canadian Zinc’s operations are subject to environmental regulation. These regulations mandate, among other things, the maintenance of water and air quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste. Environmental legislation is evolving in a manner, which will require stricter standards and enforcement, increased fines and penalties for non-compliance, and more stringent environmental assessments of proposed projects. United Nations proposals for a global treaty on mercury, intended to result in reduced global emissions of mercury, may place restrictions on the production, use and international movement of mercury and mercury-containing wastes which may, if adopted, result in restrictions on shipment of concentrates or other mineral products containing by-product or trace mercury.

There is no assurance that future changes in environmental laws or regulations, if any, will not adversely affect Canadian Zinc’s operations.

Environmental laws and regulations are complex and have tended to become more stringent over time. These laws are continuously evolving. Any changes in such laws, or in the environmental conditions at the Prairie Creek Property, could have a material adverse effect on Canadian Zinc’s financial condition, liquidity or results of operations. Canadian Zinc is not able to determine the impact of any future changes in environmental laws and regulations on its future financial position due to the uncertainty surrounding the ultimate form such changes may take. The Company does not currently consider that its expenditures required to maintain ongoing environmental monitoring obligations at the Prairie Creek Property are material to the results and financial condition of the Company. However, these costs could become material in the future and would be reported in the Company’s public filings at that time.

Although Canadian Zinc makes provision for reclamation costs, it cannot be assured that these provisions will be adequate to discharge its obligations for these costs. As environmental protection laws and administrative policies change, Canadian Zinc will revise the estimate of its total obligations and may be obliged to make further provisions or provide further security for mine reclamation cost. The ultimate amount of reclamation to be incurred for existing and past mining interests is uncertain.

Existing and possible future environmental legislation, regulations and actions could cause additional expense, capital expenditures, restrictions and delays in the activities of the Company, the extent of which cannot be predicted. Before production can commence on the Prairie Creek Property the Company must obtain regulatory approval, permits and licences and there is no assurance that such approvals will be obtained. No assurance can be given that new rules and regulations will not be enacted or made, or that existing rules and regulations will not be applied, in a manner which could limit or curtail production or development.

Regulatory approvals and permits are currently, and will in the future be, required in connection with Canadian Zinc’s operations. To the extent such approvals are required and not obtained, Canadian Zinc may be curtailed or prohibited from proceeding with planned exploration or development of its mineral properties or from continuing its mining operations.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or remedial actions. The Company may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations.

Failure to comply with applicable environmental and health and safety laws can result in injunctions, damages, suspension or revocation of permits and imposition of penalties. There can be no assurance that Canadian Zinc has been or will be at all times in complete compliance with all such laws, regulations and permits, or that the costs of complying with current and future environmental and health and safety laws and permits will not materially adversely affect Canadian Zinc’s business, results of operations or financial condition. Environmental hazards may exist on the properties, including the Prairie Creek Property, on which Canadian Zinc holds interests which are unknown to Canadian Zinc at present and which have been caused by previous owners or operators of the properties.

Amendments to current laws, regulations and permits governing operations and activities of mining and exploration companies, or more stringent implementation thereof, could have a material adverse impact on Canadian Zinc and cause increases in exploration expenses, capital expenditures or production costs or require abandonment or delays in the development of mining properties.

The Prairie Creek Project has, on numerous occasions, experienced significant delays in obtaining permits and licences necessary for the conduct of its operations. If at any time in the future permits essential to operations are not obtained, or not obtained in a timely manner, or exemptions not granted, there is a risk that the Company will never operate a mine at the Prairie Creek Property.

Political and Legislative

Canadian Zinc conducts its operations in Canada and specifically the province of Newfoundland and Labrador and the Northwest Territories of Canada. The Mackenzie Valley in the Northwest Territories of Canada is in an area which is claimed by the Dehcho First Nations as their traditional territory. The Dehcho have not settled their land claim with the Federal Government of Canada. The Dehcho and the Federal Government both claim legal title to this territory and legal title to the land remains in dispute. The Company’s operations are potentially subject to a number of political, legislative and other risks. Canadian Zinc is not able to determine the impact of political, legislative or other risks on its business or its future financial position.

Canadian Zinc’s operations are exposed to various levels of political, legislative and other risks and uncertainties. These risks and uncertainties include, but are not limited to, cancellation, renegotiation or nullification of existing leases, claims, permits and contracts; expropriation or nationalization of property; changes in laws or regulations; changes in taxation laws or policies; royalty and tax increases or claims by governmental, Aboriginal or other entities; retroactive tax or royalty claims and changing political conditions; government mandated social expenditures; governmental regulations or policies that favour or require the awarding of contracts to local or Aboriginal contractors or require contractors to employ residents of, or purchase supplies from, a particular jurisdiction or area; or that require that an operating project have a local joint venture partner, which may require to be subsidized; and other risks arising out of sovereignty or land claims over the area in which Canadian Zinc’s operations are conducted.

The mineral exploration, mine development, and proposed mining, processing activities of Canadian Zinc, and the anticipated production, transportation and sale of mineral concentrates are subject to extensive federal, territorial, international and local laws, regulations and treaties, including various laws governing prospecting, development, production, transportation taxes, labour standards and occupational health, mine safety, toxic substances including mercury, land use, water use and other matters. Such laws and regulations are subject to change and can become more stringent and costly over time. No assurance can be given that new laws, rules and regulations will not be enacted or that existing laws, rules and regulations will not be applied in a manner which could limit or curtail exploration, development, mining, processing, production and sale of concentrates. Amendments to current laws and regulations governing operations and activities of exploration and mining, or more stringent implementation thereof, could have a substantial adverse impact on Canadian Zinc.

There was a major change to the legislative and regulatory framework and regulations in the Mackenzie Valley between 1998 and 2000. There can be no assurance that these laws and regulations will not change in the future in a manner that could have an adverse effect on the Company’s activities and/or its financial condition. In 2007, the Federal Government announced the Northern Regulatory Improvement Initiative to improve the current regulatory regime in the north of Canada and in May 2010 announced an Action Plan to improve northern regulatory regimes, which anticipate changes to the current legislative framework and regulatory processes.

In relation to Northwest Territories specifically, a number of policy and social issues exist which increase Canadian Zinc’s political and legislative risk. The Government of Canada is facing legal and political issues, such as land claims and social issues, all of which may impact future operations. This political climate increases the risk of the Government making changes in the future to its position on issues such as mining rights and land tenure, which in turn may adversely affect Canadian Zinc’s operations. Future government actions cannot be predicted, but may impact the operation and regulation of the Prairie Creek mine. Changes, if any, in Government policies, or shifts in local political attitude in the Northwest Territories may adversely affect Canadian Zinc’s operations or business.

On March 11, 2013, the Prime Minister of Canada announced that negotiators had reached consensus on the terms for the devolution of lands and resource management from the Government of Canada to the Government of the Northwest Territories. Devolution in the NWT will mean the transfer of decision-making and administration for land and resource management from the Government of Canada to the Government of the Northwest Territories. The territorial government will become responsible for the management of onshore lands and the issuance of rights and interests with respect to onshore minerals and oil and gas. It will also give them the power to collect and share in resource revenues generated in the territory. With the conclusion of negotiations, the Government of Canada will begin a second round of consultations to gather input from Aboriginal organizations in the NWT and other stakeholders, which will lead to a Final Devolution Agreement. The governments are working toward an effective date of April 1, 2014.

Canadian Zinc’s exploration, development and production activities may be substantially affected by factors beyond Canadian Zinc’s control, any of which could materially adversely affect Canadian Zinc’s financial position or results of operations. The occurrence of these various factors and uncertainties cannot be accurately predicted. The Company is not able to determine the impact of these risks on its business.

Metal Prices and Market Sentiment

The market price of metals and minerals is volatile and cannot be controlled. Metal prices have fluctuated widely, particularly in recent years. If the price of metals and minerals should drop significantly, the economic prospects for the Prairie Creek Project could be significantly reduced or rendered uneconomic. There is no assurance that, even if commercial quantities of ore are delineated, a profitable market may exist for the sale of products, including concentrates from that ore. Factors beyond the control of the Company may affect the marketability of any minerals discovered or concentrates produced. The marketability of minerals is affected by numerous other factors beyond the control of the Company, including quality issues, impurities, government regulations, royalties, allowable production and importing and exporting of minerals, the effect of which cannot be accurately predicted. Factors tending to affect the price of metals include:

• The relative strength of the U.S. dollar against other currencies;

• Government monetary and fiscal policies;

• Expectations of the future rate of global monetary inflation and interest rates;

• General economic conditions and the perception of risk in capital markets;

• Political conditions including the threat of terrorism or war;

• Speculative trading;

• Investment and industrial demand; and

• Global production and inventory stocks.

The effects of these factors, individually or in aggregate, on the prices of zinc, lead and/or silver is impossible to predict with accuracy. Fluctuations in metal prices may adversely affect Canadian Zinc’s financial performance and results of operations. Further, if the market price of zinc, lead and/or silver falls or remains depressed, Canadian Zinc may experience losses or asset write-downs and may curtail or suspend some or all of its exploration, development and mining activities.

Furthermore, sustained low metal prices can halt or delay the development of new and existing projects; reduce funds available for mineral exploration and may result in the recording of a write-down of mining interests due to the determination that future cash flows would not be expected to recover the carrying value.

Metal prices fluctuate widely and are affected by numerous factors beyond Canadian Zinc’s control such as the sale or purchase of such commodities by various central banks and financial institutions, interest rates, exchange rates, inflation or deflation, fluctuation in the value of the United States dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of major mineral and metal producing countries throughout the world. Future production, if any, from Canadian Zinc’s mining properties is dependent on mineral prices that are adequate to make these properties economic. The prices of metals have fluctuated widely in recent years, and future or ongoing serious price declines could cause continued development of and commercial production from Canadian Zinc’s properties to be impracticable. Depending on the price of metal, cash flow from mining operations may not be sufficient and Canadian Zinc may never commence commercial production and may lose its interest in, or may be forced to sell, its properties.

In addition to adversely affecting Canadian Zinc’s reserve or resource estimates and its financial condition, declining commodity prices can impact operations by requiring a reassessment of the feasibility of a particular project. The need to conduct such a reassessment may cause substantial delays or may interrupt operations until the reassessment can be completed.

Currency fluctuations may affect the costs that Canadian Zinc incurs at its operations. Zinc, lead and silver are sold throughout the world based principally on the U.S. dollar price, but operating expenses are incurred in currencies other than the U.S. dollar. Appreciation of the Canadian dollar against the U.S. dollar increases the cost of production in U.S. dollar terms at mines located in Canada.

The development of the Company’s properties will depend upon the Company’s ability to obtain financing through private placement financing, public financing, the joint venturing of projects, bank financing or other means. There is no assurance that the Company will be successful in obtaining the required financing.

Securities of junior and small-cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. These factors include macroeconomic developments in North America and global and market perceptions of the attractiveness of particular industries. The share price of Canadian Zinc is likely to be significantly affected by short-term changes in metal prices. Other factors unrelated to Canadian Zinc’s performance that may have an effect on the price of its shares include the following: the extent of analytical coverage available to investors concerning Canadian Zinc’s business may be limited if investment banks with research capabilities do not follow the Company’s securities; lessening in trading volume and general market interest in the Company’s securities may affect an investor’s ability to trade significant numbers of common shares; the size of Company’s public float may limit the ability of some institutions to invest in the Company’s securities; and a substantial decline in the price of the common shares that persists for a significant period of time could cause the Company’s securities to be delisted from an exchange, further reducing market liquidity.

As a result of any of these factors, the market price of the Company’s shares at any given point in time may not accurately reflect Canadian Zinc’s long-term value. Securities class action litigation often has been brought against companies following periods of volatility in the market price of their securities. Canadian Zinc may in the future be the target of similar litigation. Securities litigation could result in substantial costs and damages and divert management’s attention and resources.

The development and exploration of Canadian Zinc’s property will require substantial additional financing. Failure to obtain sufficient financing will result in delaying or indefinite postponement of exploration, development or production on Canadian Zinc’s property or even a loss of property interest. There can be no assurance that additional capital or other types of financing will be available when needed or that, if available, the terms of such financing will be favourable to Canadian Zinc.

Exploration and Evaluation

The business of exploring for minerals and mining involves a high degree of risk. There is no assurance the Company’s mineral exploration activities will be successful. Few properties that are explored are ultimately developed into producing mines. In exploring and developing its mineral deposits the Company is subjected to an array of complex economic factors and technical considerations. Unusual or unexpected formations, formation pressures, power outages, labour disruptions, flooding, explosions, cave-ins, landslides, environmental hazards, and the inability to obtain suitable or adequate machinery, equipment or labour are other risks involved in the conduct of exploration and development programs. Such risks could materially adversely affect the business or the financial performance of the Company.

There is no certainty that the expenditures made by Canadian Zinc towards the search and evaluation of mineral deposits will result in discoveries of commercial quantities of ore. The exploration for and development of mineral deposits involves significant risks which even a combination of careful evaluation, experience and knowledge may not eliminate. Major expenses may be required to locate and establish mineral reserves, to develop metallurgical processes and to construct mining and processing facilities at a particular site. It is impossible to ensure that the exploration or development programs planned by Canadian Zinc will result in a profitable commercial mining operation. Whether a mineral deposit will be commercially viable depends on a number of factors, some of which are: the particular attributes of the deposit, such as size, grade and proximity to infrastructure; metal prices which are highly cyclical; and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in Canadian Zinc not receiving an adequate return on invested capital.

A specific risk associated with the Prairie Creek Property is its remote location. Mining, processing, development and exploration activities depend, to one degree or another, on adequate infrastructure. Reliable roads, bridges, power sources and water supply are important factors, which affect capital and operating costs. Unusual or infrequent weather phenomena, government or other interference in the maintenance or provision of such infrastructure could adversely affect Canadian Zinc’s operations, financial condition and results of operations.

Mining operations generally involve a high degree of risk. Canadian Zinc’s mining operations will be subject to all the hazards and risks normally encountered in the development and production of minerals, including unusual and unexpected geologic formations, seismic activity, rock bursts, cave-ins, flooding and other conditions involved in the drilling and removal of material, any of which could result in damage to, or destruction of, mines and other producing facilities, damage to life or property, environmental damage and possible legal liability. Mining and milling operations are subject to hazards such as equipment failure or failure of retaining dams around tailings disposal areas, which may result in environmental pollution and consequent liability.

Uncertainty in the Estimation of Mineral Resources

The figures for Mineral Resources contained in this document are estimates only and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that Mineral Resources can be mined or processed profitably. There are numerous uncertainties inherent in estimating Mineral Resources, including many factors beyond Canadian Zinc’s control. Such estimation is a subjective process, and the accuracy of any resource estimate is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation. In addition, there can be no assurance that mineral or metal recoveries in small scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.

Inferred mineral resources do not have demonstrated economic viability. Due to the uncertainty which may attach to inferred mineral resources, there is no assurance that inferred mineral resources will be upgraded to measured and indicated mineral resources as a result of continued exploration.

Fluctuation in metal prices, results of drilling, metallurgical testing and production and the evaluation of mine plans subsequent to the date of any estimate may require revision of any such resource or reserve estimate. The volume and grade of resources mined and processed and recovery rates may not be the same as currently anticipated. Any material reductions in estimates of Mineral Resources, or of Canadian Zinc’s ability to extract these Mineral Resources, could have a material adverse effect on Canadian Zinc’s results of operations and financial condition.

Mineral reserve and mineral resource estimates are imprecise and depend partly on statistical inferences drawn from drilling and other data which may prove to be unreliable. Future production could differ dramatically from mineral resource estimates for many reasons including the following:

• Mineralization or formations could be different from those predicted by drilling, sampling and similar examinations;

• Declines in the market price of metals may render the mining of some or all of Canadian Zinc’s mineral resources uneconomic;

• Increases in operating mining costs and processing costs could adversely affect mineral reserves or resources; and

• The grade of mineral reserves or resources may vary significantly from time to time and there can be no assurance that any particular level of metal may be recovered from the mineral reserves or resources.

Any of these factors may require Canadian Zinc to reduce its mineral reserve or mineral resources estimates.

Insurance and Uninsured Risks

Canadian Zinc’s business is subject to a number of risks and hazards generally, including adverse environmental conditions, industrial accidents, labour disputes, unusual or unexpected geological conditions, ground or slope failures, cave-ins, changes in the regulatory environment and natural phenomena such as inclement weather conditions, floods and earthquakes. Such occurrences could result in damage to mineral properties or production facilities, personal injury or death, environmental damage to Canadian Zinc’s properties or the properties of others, delays in mining, monetary losses and possible legal liability.

Although Canadian Zinc maintains insurance to protect against certain risks in such amounts as it considers reasonable, its insurance will not cover all the potential risks associated with the Company’s mining operations. Canadian Zinc may also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage may not continue to be available or may not be adequate to cover any resulting liability. Moreover, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available to Canadian Zinc or to other companies in the mining industry on acceptable terms. In particular, the Company is not insured for environmental liability or earthquake damage.

Canadian Zinc might also become subject to liability for pollution or other hazards which may not be insured against, or which Canadian Zinc may elect not to insure against, because of premium costs or other reasons. Losses from these events may cause Canadian Zinc to incur significant costs that could have a material adverse effect upon its financial performance and results of operations.

Executives and Conflicts of Interest

Canadian Zinc is dependent on the services of key executives, including the President and Chief Executive Officer and the Vice President of Exploration and Chief Operating Officer of the Company, and a small number of other skilled and experienced executives and personnel. Due to the relatively small size of the Company, the loss of these persons or Canadian Zinc’s inability to attract and retain additional highly skilled or experienced employees may adversely affect its business and future operations.

Certain of the directors and officers of the Company also serve as directors and/or officers of, or have significant shareholdings in, other companies involved in natural resource exploration and development and consequently there exists the possibility for such directors and officers to be in a position of conflict. Two directors of Canadian Zinc also serve as directors of Vatukoula Gold Mines plc. Any decision made by any of such directors and officers involving Canadian Zinc will be made in accordance with their duties and obligations to deal fairly and in good faith with a view to the best interests of the Company and its shareholders. In addition, each of the directors is required to declare and refrain from voting on any matter in which such directors may have a conflict of interest in accordance with the procedures set forth in the Business Corporations Act (British Columbia) and other applicable laws.

To the extent that such other companies may participate in ventures in which Canadian Zinc may participate, the directors of Canadian Zinc may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In the event that such a conflict of interest arises at a meeting of the Company’s directors, a director who has such a conflict will abstain from voting for the approval of such participation or such terms.

From time to time several companies may collectively participate in the acquisition, exploration and development of natural resource properties thereby allowing for their participation in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in respect of any one program. It may also occur that a particular company will assign all or a portion of its interest in a particular program to another of these companies due to the financial position of the company making the assignment. Under the laws of the Province of British Columbia, the directors of the Company are required to act honestly, in good faith and in the best interests of the Company. In determining whether or not Canadian Zinc will participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider the degree of risk to which the Company may be exposed and its financial position at that time.

Title Matters

Mining leases and surface leases issued to the Company by the Federal Government have been surveyed but other parties may dispute the Company’s title to its mining properties. The mining claims in which the Company has an interest have not been surveyed and, accordingly, the precise location of the boundaries of the claims and ownership of mineral rights on specific tracts of land comprising the claims may be in doubt. These claims have not been converted to lease, and are, accordingly, subject to regular compliance with assessment work requirements.

Failure to comply strictly with applicable laws, regulations and local practices relating to mineral right applications and tenure, could result in loss, reduction or expropriation of entitlements.

While the Company has investigated its title to all its mining leases, surface leases and mining claims and, to the best of its knowledge, title to all properties is in good standing, this should not be construed as a guarantee of title and title may be affected by undetected defects. The validity and ownership of mining property holdings can be uncertain and may be contested. There are currently a number of pending Aboriginal or Native title or Treaty or traditional land ownership claims relating to Northwest Territories. The Company’s properties at Prairie Creek are subject to Aboriginal or Native land claims. Title insurance generally is not available, and Canadian Zinc’s ability to ensure that it has obtained secure title to individual mineral properties or mining concessions may be severely constrained. Canadian Zinc’s mineral properties may be subject to prior unregistered liens, agreements, transfers or claims, including Native land claims, and title may be affected by, among other things, undetected defects. No assurances can be given that there are no title defects affecting such properties.

Competition

The mining industry is competitive in all of its phases. There is aggressive competition within the mining industry for the discovery and acquisition of properties considered to have commercial potential. Canadian Zinc faces strong competition from other mining companies in connection with the acquisition of properties, mineral claims, leases and other mineral interests as well as for the recruitment and retention of qualified employees and other personnel. Many of these companies have greater financial resources, operational experience and technical capabilities than Canadian Zinc. As a result of this competition, Canadian Zinc may be unable to maintain or acquire attractive mining properties on terms it considers acceptable or at all. Consequently, Canadian Zinc’s operations and financial condition could be materially adversely affected.

Acquisitions

From time to time Canadian Zinc undertakes evaluations of opportunities to acquire additional mining assets and businesses. Any resultant acquisitions may be significant in size, may change the scale of Canadian Zinc’s business, and may expose Canadian Zinc to new geographic, political, operating financial and geological risks. Canadian Zinc’s success in its acquisition activities depends on its ability to identify suitable acquisition candidates, to acquire them on acceptable terms, and integrate their operations successfully with those of Canadian Zinc. Any acquisition would be accompanied by risks, such as a significant decline in metal prices; the ore body proving to be below expectations; the difficulty of assimilating the operation and personnel; the potential disruption of Canadian Zinc’s ongoing business; the inability of management to maximize the financial and strategic position of Canadian Zinc through the successful integration of acquired assets and businesses; the maintenance of uniform standards, control, procedures and policies; the impairment of relationships with employees, customers and contractors as a result of any integration of new management personnel; and the potential unknown liabilities associated with acquired assets and business. In addition Canadian Zinc may need additional capital to finance an acquisition. Debt financing related to any acquisition will expose Canadian Zinc to the risk of leverage, while equity financing may cause existing shareholders to suffer dilution. There can be no assurance that Canadian Zinc would be successful in overcoming these risks or any other problems encountered in connection with such acquisitions.

Vatukoula Gold Mines plc

As discussed at in this Annual Information Form, the Company holds a 10.7% interest in Vatukoula Gold Mines plc, which operates the Vatukoula Gold Mine in Fiji. Operations in Fiji add increased risks to the Company’s business affairs. Fiji has experienced political unrest and there may, at times, be challenges to foreign owned companies. In Fiji, VGM expenditures are made in Fijian dollars and revenues are in U.S. dollars. The parent company in the VGM group is based in the United Kingdom and reports in £ Sterling. The impact of foreign exchange fluctuations may have a material impact on the results of operations of VGM. As VGM is operating a working gold mine, it is exposed to risk from changes in commodity prices (notably gold) and also the price of oil on the world markets. Adverse changes in these prices could have a material impact on the operations of VGM and therefore the share price of VGM. On March 18, 2013, the value of the Company’s investment in VGM was $3.4 million.

Since 2007, the Company has documented and tested its internal control procedures in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”), which requires an annual assessment by management of the effectiveness of the Company’s internal control over financial reporting and an attestation by the Company’s independent auditors addressing internal controls over financial reporting.

Due to its size, its limited staff resources and financial constraints, the Company is exposed to certain potential deficiencies in its internal controls over financial reporting. If the Company is unable to maintain the adequacy of its internal control over financial reporting, as such standards are modified, supplemented, or amended from time to time, the Company may not be able to ensure that it can conclude on an ongoing basis that it has effective internal controls over financial reporting in accordance with Section 404 of SOX. The Company’s inability to satisfy the requirements of Section 404 of SOX on an ongoing, timely basis could result in the loss of investor confidence in the reliability of its consolidated financial statements, which in turn could harm the Company’s business and negatively impact the trading price of its common shares. In addition, any failure to implement required new or improved controls, or difficulties encountered in their implementation, could impact the Company’s operating results or cause it to fail to meet its reporting obligations. Future acquisitions (if any) may provide the Company with challenges in implementing the required processes, procedures and controls in the acquired operations. Acquired companies may not have disclosure controls and procedures or internal control over financial reporting that are as thorough or effective as those required by securities laws currently applicable to the Company.

No evaluation can provide complete assurance that the Company’s internal control over financial reporting will detect or uncover all failures of persons within the Company to disclose material information otherwise required to be reported. The effectiveness of the Company’s controls and procedures could also be limited by simple errors or faulty judgments. In addition, as the Company continues to develop, the challenges involved in implementing appropriate internal controls over financial reporting will increase and will require that the Company continue to enhance its internal controls over financial reporting. Although the Company will be required to devote substantial time and will incur substantial costs, as necessary, in an effort to ensure ongoing compliance, the Company cannot be certain that it will be successful in continuing to comply with Section 404 of SOX.

History of Losses and No Assurance of Profitable Operations

The Company has incurred losses since inception of $81.9 million through December 31, 2012. There can be no assurance that the Company will be able to operate profitably during future periods. If the Company is unable to operate profitably during future periods, and is not successful in obtaining additional financing, the Company could be forced to cease its exploration and development plans as a result of lacking sufficient cash resources.

Shareholder Dilution

As of December 31, 2012, there were 164,031,781 common shares outstanding. As of December 31, 2012, the Company had 7,605,533 share purchase options and 13,419,693 warrants outstanding allowing the holders to purchase 21,025,226 common shares. Directors and officers of the Company hold 5,100,000 of these share purchase options, contractors and employees of the Company hold 2,505,533 share purchase options and third-party entities hold 13,419,693 share purchase warrants. As of March 19, 2013, there were 164,031,781 common shares outstanding and the Company had 7,564,053 share purchase options and 13,419,693 warrants outstanding allowing the holders to purchase 20,983,746 common shares. The exercise of all of the existing share purchase options and warrants would result in percentage ownership dilution to the existing shareholders.

Potential Future Equity Financings

The Company has used equity financing in order to meet its needs for capital and may engage in equity financings during future periods. Subsequent issuances of equity securities or securities convertible into or exchangeable or exercisable for equity securities would result in further percentage ownership dilution to existing shareholders and could depress the price of the Company’s shares.

DIVIDENDS AND DISTRIBUTIONS

No dividends have been paid by the Company to date. The Company anticipates that it will retain all future earnings and other cash resources for the future operation and development of its business and the Company does not intend to declare or pay any cash dividends in the foreseeable future. Payment of any future dividends will be at the discretion of the Company’s board of directors after taking into account many factors, including the Company’s operating results, financial condition and current and anticipated cash needs.

CAPITAL STRUCTURE

Canadian Zinc's capital structure consists of only one class of common shares without par value, with an unlimited authorized capital. Each common share is entitled to one vote and all common shares rank equally for the payment of dividends and for all distributions, whether upon dissolution, a winding up or otherwise. At December 31, 2012, the Company had 164,031,781 shares issued and outstanding. At March 19, 2013, the Company had 164,031,781 shares issued and outstanding. At December 31, 2012, the Company also had 7,605,533 stock options outstanding and 13,419,693 warrants outstanding. At March 19, 2013, the Company had 7,564,053 options outstanding and 13,419,693 warrants outstanding. Each stock option and each warrant entitles the holder to purchase one common share.

Details regarding the Company’s outstanding options are as follows:

Since the commencement of the Company’s most recently completed financial year (January 1, 2012) there has not been a recommendation of the Audit Committee to nominate or compensate an external auditor which was not adopted by the Board of Directors.

Pre-Approval Policies and Procedures

The Audit Committee has adopted procedures requiring Audit Committee review and approval in advance of all particular engagement for services provided by the Auditors. Consistent with applicable laws, the procedures permit limited amounts of services, other than audit services, to be approved by the Audit Committee provided the Audit Committee is informed of each particular service. All of the engagements and fees for fiscal 2012 and 2011 were approved by the Audit Committee. The Audit Committee reviews with the auditors whether non-audit services to be provided, if any, are compatible with maintaining the auditor’s independence.
