SUMMARY
Kirkland Lake Gold Inc. (KLG) engaged Glenn R. Clark & Associates Limited (GRCA) to review the Resources and Reserves of the Macassa Mine at Kirkland Lake, Ontario, Canada. The review was made by Glenn R. Clark, P.Eng., in compliance with the requirements of National Instrument 43-101 for technical reports. The property was visited June 24-27, 2006.
Property:
The Macassa Mine is in the Municipality of Kirkland Lake within Teck Township, District of Timiskaming, in the eastern part of Northern Ontario, Canada. Macassa is at approximately 48°10’ N Latitude and 80°2’ W Longitude at an elevation of approximately 1000 feet (305 m). Kirkland Lake is approximately 370 miles (600 km) by road north of Toronto.
The Macassa Mine started production in 1933.
KLG holds title to 224 mining claims covering 8842 acres in Teck and Lebel Townships. There are 174 patented claims, 5 crown grants and 45 staked claims.
History:
The Kirkland Lake mining camp has been a prolific gold producer since mining began in 1915. The Macassa Mine and the 4 former producers that KLG now owns have produced about 22 million ounces of gold since 1917. The production from these 5 mines accounts for about 90% of the production from the 7 mines in the Kirkland Lake mining camp.
The Macassa Mine started processing ore in October 1933. The first mill on the property began processing the ore at a rate of 200 tons per day. The milling rate increased over the years. In 1988 a new mill was built which could process 500 to 600 tons of rock and 750 tons of tailings per day. The current configuration can process about 1500 tons per day of mine ore.
In 1986, the No. 3 Shaft was sunk from surface to 7,300 ft. This shaft was the deepest single lift shaft in the Western Hemisphere.
Rock burst activity was quite common in the deeper sections of the mines in the Kirkland Lake camp. Macassa was not an exception and in November 1993 a rock burst collapsed 2 stopes

at the 6700 level and in April 1997 damaged the No. 3 shaft at the 5800 level. Both these occurrences created work stop interruptions at the mine otherwise it would have operated continuously from 1933 to 1999. The rock burst on April 12, 1997 limited mining to levels between 4,250 ft. and 5,150 ft.
Operations at Macassa were suspended in 1999 due to the declining price of gold. The workings were allowed to flood in 2000.
From 1933 to 1999, Macassa produced about 3.5 million ounces of gold from 7.9 million tons of ore. The head grade during that period averaged 0.47 oz Au/ton and the recovered grade was 0.45 oz Au/ton.
In May of 2002 the Macassa mill was restarted and processed Lake Shore tailings at a rate of 880 tons per day. An additional 45 thousand tons of surface rock from Lake Shore and the Teck-Hughes properties were also processed.
In December 2002 underground mining at Macassa recommenced.
Corporate History:
Macassa Mines Ltd. was incorporated in 1926 and evolved through a succession of mergers to become a division of Lac Minerals Ltd. in 1982. The merger consolidated the properties of the Little Long Lac group into the one entity and the Macassa Mine and the other Kirkland Lake properties were included.
Lac Minerals was acquired by Barrick Gold Corporation in August 1994. After a short period of operation by Barrick the property was sold to Kinross in May 1995. Foxpoint purchased the Kirkland Lake properties of Kinross in December 2001. This purchase included the Macassa Mine and all of the plant.
Foxpoint changed its name to Kirkland Lake Gold Inc. in October 2002.
KLG purchased the mining assets that Kinross owned in and around Kirkland Lake for $5 million and the assumption of $2 million in reclamation bond obligations related to the closure plan for the properties. In addition, royalties must be paid to Kinross and previous property holders.

Geology:
The Kirkland Lake mining camp is located in the west portion of the Archean Abitibi greenstone belt of the Abitibi Subprovince that forms part of the Superior Province in the Precambrian Shield.
The Timiskaming Group of rocks is the main feature of the Kirkland Lake area. It is up to 10,500 feet thick and extends for about 40 miles from Kenogami Lake in the west to the Quebec border in the east. In the Kirkland Lake area, the Timiskaming is predominantly conglomerates and sandstones, trachytic lava flows and pyroclastic tuffs. The Timiskaming trends N65°E and dips steeply south at Kirkland Lake. Immediately east of Kirkland Lake, the formations are warped to an east-southeast direction and then return to an east-northeast direction at Larder Lake and continue this way to the Québec border.
The Timiskaming sediments are intruded by syenite porphyries and lamprophyre dykes and sills. Alkali stocks have intruded the Timiskaming Group and the supracrustal assemblage along the south margin of the synclinorium. Matachewan diabase dykes trending north-northeast cut all rocks in the area.
At the Macassa Mine the Timiskaming tuffs, conglomerates and the syenite porphyries are encountered. The syenites are the preferential hosts of the gold mineralization. Most of the mine workings are also in the syenites.
The Kirkland Lake-Larder Lake Break, and its associated splay faults and fracture system, forms a complex, major structural feature which transects and follows the trend of the Timiskaming Group at Kirkland Lake. This Break can be traced for about 200 miles from Matachewan in the west of Kirkland Lake all the way to the Grenville Front east of Louvicourt, Quebec. As well as Kirkland Lake, it passes through, or near, the important mining areas of Larder Lake, Rouyn-Noranda, Cadillac, Malartic, Val d’Or and Louvicourt. Numerous gold occurrences and gold mines are spatially related to this regional structure.
The fault or break system that hosts the Kirkland Lake gold deposits is north of the main Kirkland Lake-Larder Lake Break.
At Macassa, the Kirkland Lake structures have been mined from 2,175 ft. to 5,600 ft. (660 m to 1,700 m) with the Main Break being the most important zone in the eastern part of the mine. The ‘04’ Break is in the western part of the property and is the main producing break at Macassa. It has been mined from the 4375 Level (1,330 m) to the bottom of the mine and it is known to continue deeper.

KLG has discovered the D zones and other zones to the south of the historically productive main structures in the Kirkland lake Camp. These significant new zones are flatter lying and strike almost perpendicular to the main structures. The D zones strike generally to the NE and dip at about 35° to the south.
Mineralization:
The gold mineralization is located along the breaks and subordinate splays as individual fracture fill quartz veins from several inches to as thick as 12 feet. Veins may be of single, sheeted or stacked morphology. Several generations of quartz deposition are evident from colour and textural variability and vein quartz is generally fractured.
The presence of a fault splay is often a prerequisite for gold deposition. Broader zones of mineralized brecciated and fragmented quartz are found in the footwall and hanging wall of major faults.
Gold is usually accompanied by 1% to 3% pyrite and sometimes is associated with molybdenite and/or tellurides. Silver is present both amalgamated with the gold and in tellurides.
The presence of pyrite and silicification does not guarantee gold, however, higher grade gold is almost always accompanied by increased percentages of pyrite and silica.
The new discoveries to the south generally are of a different style of mineralization - wide sulphide systems rather than the quartz vein mineralization on the Main Break complex. These new, wide, zones are carbonate altered conglomerate mineralized with up to 10% disseminated pyrite.
Resources and Reserves:
The estimation of the resources and reserves was carefully completed by the Macassa geological staff, under the supervision of M. Sutton. The methods used and the classification of the resources and reserves meet the requirements of National Instrument (NI) 43-101.
The Proven and Probable Reserves were diluted depending on the mining method and the size and the width of the zone. The average dilution for these estimations was 28%. All the dilution was accounted for at a grade of 0.02 oz Au/ton.
| Glenn R. Clark & Associates Ltd. | Page 7 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
The Proven and Probable Reserves are only 94.2% of the estimated size of the zones to allow for recovery losses due to pillars and other reasons.
The Proven and Probable Reserves are considered recoverable by mining.
The Measured and Indicated Resources have not been diluted and a recovery factor has not been applied.

Note 1: Mining of the reserves below the 5300 Level is dependent on the current restriction imposed by the Ministry of Labour being removed. There is a reasonable expectation that this will be done when KLG presents a new mining plan. |
The total of the Estimated Proven and Probable Reserves at April 30, 2006 is 2.31 million tons at a grade of 0.47 oz Au/ton.
The total of the Estimated Measured and Indicated Resources at April 30, 2006 is 1.97 million tons at a grade of 0.35 oz Au/ton.
In addition, there is an estimated 1.05 million tons at a grade of 0.50 oz Au/ton that is classified as an Inferred Resource.

Mining and Processing:
Mining and processing at Macassa has been carried out since 1933. The mineral extraction has been from underground stopes. The processing has been done on the property.
The Macassa Mine employs conventional drill and blast mining methods to extract the ore. Access to the mining areas is by shafts.
The ore is processed by conventional cyanide leaching with a carbon-in-pulp recovery system.
The KLG forecast is to mine and process 180,000 tons per year starting in the current year. The head grade anticipated for the current year is 0.44 oz Au/ton increasing over the next few years to 0.47 oz Au/ton. Gold recovery is forecast at approximately 77,500 ounces in the current year and increasing to approximately 82,000 as the grade increase in the next few years.
Mining Method:
Mining is by cut and fill or long hole methods. Level trains move the ore to the main ore passes for hoisting to surface.
All of the stopes are now being filled with paste backfill. Previously the stopes were filled with cemented rock fill.
These mining methods recover about 94.2% of the ore.
Accessing below the 5300 Level:
As was stated earlier, due to the shaft being damaged below the 5700 level the Ministry of Labour restricted mining to the area above the 5300 Level. This effectively sterilized a large part of the known resources at Macassa.
KLG has been working with Knight Piésold Ltd. a consulting firm and a preliminary plan, including the costs, has been developed to rehabilitate the shaft. It is anticipated that when KLG submits a request along with a detailed plan to the Ministry of Labour the restriction will be lifted.
It was on the basis of this preliminary study that the deeper ore was classified as Reserves in 2005.

Processing the Ore:
The company’s mill was built in 1988 with a modern larger mill replacing the older mill. Some modifications have taken place since then and the mill capacity now is 1500 tons of ore a day.
The ore at Macassa is treated by conventional means. These are crushing and grinding followed by cyanidation with the gold recovered from solution by the carbon-in-pulp technique. The bullion contains some silver.
Gold recovery has been good at Macassa. In the 20 year period from 1980 to 1999 the average recovery was 95.8% . KLG had a recovery of 97.6% in calendar year 2005.
The mill will be able to process all of the ore that can be delivered from the mine.
Operating Cost:
KLG has estimated the operating cost for the 12 month period from May 2006 to April 2007 (fiscal 2007). This plan calls for milling an average of 515 tons per day totalling 180,000 tons for the 12 month Period. The average head grade is forecast at 0.44 oz Au/ton and a total of approximately 77,500 oz Au will be recovered.
The forecast cash operating cost to April 2007 is $170.00 per ton.
Exploration:
KLG is actively exploring the Kirkland Lake properties to extend the known zones and find new ones. This is a 3 year $21 million program that has located some interesting gold zones. The target areas are the Main Break,Parallel Breaks and North South structures, such as the Lower D Zone, on the Company’s land holdings.
This exploration has lead to the “D” Zone that is now part of the reserves.
In a press release on July 11, 2005 KLG highlighted an intersection of 90.4 feet assaying 2.3 ounces uncut from Drill Hole 50-627.
As this intersection was 1765 feet from the collar of the hole it was decided to wedge the hole and have a second confirmatory cut of this new zone.

Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
A press release on August 15, 2005 gave the excellent results of the wedged hole. The wedged intersection intersected 1.43 oz Au/ton over 124.5 feet. The cut grade would be 0.84 oz Au/ton. The wedged hole intersected the new discovery 49 feet vertically above and 140 feet up-dip from the discovery hole, Hole 50-627.
The mineralization intersected in the wedged hole is identical to the discovery, however considerably more visible gold and tellurides were observed in the wedged hole.
These intersections are located 1,600 feet south of the active mine workings at the Company’s #3 shaft.
Other parallel zones have also been located.
The true significance of these zones will only be known after considerable exploration has been carried out and the potential size and grade can be more realistically evaluated.
KLG will continue exploring its properties. This recent find and other finds that KLG has made indicate the potential of the area.
Conclusions:
The Resources and Reserves estimates truly reflect the mineralization that is currently known. The estimates conform to the requirements of National Instrument 43-101.
In general the development and exploration program initiated by KLG should continue.
Increased exploration and development underground is necessary to establish sufficient working faces to allow flexibility in the mining sequence. More working faces will allow the rate of production to rise without sacrificing the mill head grade.
Increased tonnage to the mill will allow it to operate at the optimum level.
Recommendations:
There are two parameters in the Resource estimation that need to be monitored and modified if indicated.
1: The first is the assay capping or cutting. This can have a larger effect on the resources than the density. The capping of assays is an important part of the Resource estimations. There are a number of ways to establish the cap method and the method

July 18, 2006
used by Macassa appears to be sufficient at present. However, it is known that all zones are not the same and the cap for one zone may not be proper for another zone. Changing mineralization or even the size and distribution of the gold will affect the necessary capping level.
2: The second is the dilution. Dilution affects the Reserves more than any change that one could foresee from the density or the assay capping. Every effort should be made to monitor the dilution. This monitoring is important so that the proper dilution can be applied to the Reserve estimations.
More importantly, dilution is expensive and by monitoring the dilution it may be possible to recognize the reason and rectify it with a change in the mining practice.
This is a constant problem and the geology department and the mining department have to work together on this problem.

PROPERTY
Location:
The Macassa Mine is in the Municipality of Kirkland Lake within Teck Township, District of Timiskaming, in the eastern part of Northern Ontario, Canada. Macassa is at approximately 48°10’ N Latitude and 80°2’ W Longitude at an elevation of approximately 1000 feet (305 m).
Figure 1: Location of Macassa Mine
Access:
The Macassa Mine is at the west end of the community of Kirkland Lake. The Mine is adjacent to Highway 66 just east of Highway 11. The area is serviced by railway and bus. Although there is a small airport at Kirkland Lake there currently is no scheduled service to the airport from southern Ontario.
| Glenn R. Clark & Associates Ltd. | Page 14 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
Kirkland Lake is approximately 370 miles (600 km) by road north of Toronto.
Infrastructure:
Kirkland Lake has been a mining community since mining started at the Tough-Oakes Burnside Mine (later called the Toburn) in 1915.
Mining has been the major industry in the area. An experienced mining work force as well as mining services and equipment, are readily available in this area of northeastern Ontario and northwestern Quebéc that extends from Timmins to Val d’Or.
Power is supplied through the Ontario Hydro grid.
Climate:
Climatic conditions are typical for the central Canadian Shield, with short, mild summers and long, cold winters. Mean temperatures range from –17°C (0°F) in January, to 18°C (64°F) in July, and mean annual precipitation throughout the region ranges from 812 to 876 mm (32-35 inches).
Topography:
The area is typical of the Canadian Shield primarily covered by forest, swamps, and lakes, with relatively modest relief. Rock outcrops surrounded by glacial till are common. The till is generally not very thick but is in excess of 150 feet in some locations.
The area around the Mine is approximately 1000 feet above sea level.
Local Resources:
The area is generally forested with the spruce and poplar that are typical for this part of the country. Logging for lumber and pulpwood is still carried out in the area.
There is adequate precipitation each year, rainfall and snow. The community and the mine always have sufficient water.
Farming is not carried out in the immediate area, however 30 miles south there is an area where farming is carried out.

The Claims:
KLG holds title to 224 claims and Crown Leases in the Kirkland Lake area covering a total of 8842 acres of Teck and Lebel Townships. (Figure 2)
There are 174 patented claims covering 7892 acres. These claims are surveyed and do not require assessment work to be done each year. There are 5 Crown Leases covering 544 acres. These leases are surveyed and do not require assessment work each year. Taxes have to be paid on both the patented claims and the crown leases.
There are 45 staked claims. These claims are not surveyed and require a minimum assessment work to be done each year. In the second and all subsequent years, a minimum of $400 of assessment work per 16 ha (40 acres) claim unit per year is to be reported until a lease is applied for. The work does not have to be done on each claim as it can be spread over adjacent claims and excess work in a year can be used for proceeding years. The staked claims will not require the $400 exploration expenditures as stated above until 2009. Work on patented claims can be applied to staked claims, however work on the mining leases can not be applied to the staked claims. During the past year 1 staked claim was dropped and 1 other claim was staked.
All 224 claims are located in eastern Teck Township and western Lebel Township. They cover the properties of Macassa Mine including the Tegren property at the west end of the mine strip. To the east of Macassa the properties cover the past producing mines of Kirkland Lake Gold, Tech-Hughes, Lake Shore and Wright-Hargreaves.
A list of the claims indicated above is available in Appendix C.
KLG has two agreements with Queenston Mining.
In November 2005, KLG entered into an agreement with Queenston Mining to earn a 25% interest in the property immediately adjacent to the western boundary of the KLG property. This property known as the Kirkland Lake West property covers approximately 1.7 km of the projection of the main gold bearing structures of the Kirkland Lake camp. Once the earn-in period has been completed the project will be 50% Newmont, 25% Queenston and 25% KLG.
In 2004, KLG entered into agreement with Queenston regarding the Gracie West property that extends further west from the Kirkland Lake West property and covers approximately another 1.8 km of the projected main structures. This agreement is a 50-50 joint venture between Queenston and KLG.

Maintaining the Claims:
To maintain these mining interests in good standing, taxes must be paid to MNDM, the town of Kirkland Lake and advance royalties paid to various royalty holders. In addition the staked claims need to have assessment work done as mentioned above.
In fiscal 2006, KLG reported that the Municipal taxes were $629,914, miscellaneous taxes were $10,121 and the advance royalties were $3,000. There is sufficient excess assessment work completed that can be applied to keep all the claims in good standing without further work this year.
In addition there is an advance royalty of $10,000 per year payable on certain claims if mining takes place on them.
Royalties:
There is a net smelter return (NSR) royalty payable to Kinross until $15 million has been paid. The royalty is payable quarterly on a sliding scale based on the average price per ounce of gold bullion sold. There is no NSR if gold is below US$300 per ounce.
The following shows the sliding scale of the NSR royalty. If the average price is
Equal to or greater than US$300 but less than US$400 2%
Equal to or greater than US$400 but less than US$500 3%
Equal to or greater than US$500 4%
Some of the mining claims are also subject to royalties payable to previous owners. The royalties differ depending on the claim and range from NSR royalties of 1% to 2%, production royalties of $0.10, $0.25, $1.50, $3.00 or $4.00 per ton mined or net profits royalties of 2% to 5% while some claims have a royalty of 1% of gross proceeds from production or a net profit royalty of 20%.

PROJECT HISTORY
The Kirkland Lake mining camp has been a prolific gold producer since mining began in 1915. The Macassa Mine and the 4 former producers that KLG now owns have produced about 22 million ounces of gold since 1917. The production from these 5 mines accounts for about 90% of the production from the 7 mines in the Kirkland Lake mining camp.
The Macassa Mine started in 1933. The first shaft was sunk in the main break zone in the late 1920’s to a depth of 500 feet, however sufficient gold was not located and operations were halted. In 1931 the Macassa property was entered underground at the east end of the property from the adjacent Kirkland Lake Gold Mine from the 2475 level. This entry was successful in finding the gold and in October 1933 the first mill on the property began processing the ore at a rate of 200 tons per day. The milling rate was increased to 425 tons per day in 1949 and to 500 to 525 tons per day in 1956. In August 1988 a new mill was built which could process 500 to 600 tons of rock and 750 tons of tailings per day. By 1996, modifications had increased capacity to 900 tons of rock per day and 1,000 tons of tailings per day. When mining was suspended in 1999, mill capacity was near 1,500 tons of rock per day.
In 1986, the No. 3 Shaft was sunk from surface to 7,300 ft. This shaft was the deepest single lift shaft in the Western Hemisphere.
Starting in 1988 and until October 1999, the tailings from the Lake Shore Mine were processed at Macassa. These tailings were recovered by either dry mining or by dredging.
Rock burst activity was quite common in the deeper sections of the mines in the Kirkland Lake camp. Macassa was not an exception and in November 1993 a rock burst collapsed 2 stopes at the 6700 level and in April 1997 damaged the No. 3 shaft at the 5800 level. Both these occurrences created work stop interruptions at the mine, otherwise it would have operated continuously from 1933 to 1999. The rock burst on April 12, 1997 limited mining to levels between 4,250 ft. and 5,150 ft.
Operations at Macassa were suspended in 1999 due to the declining price of gold. The workings were allowed to flood in 2000.
From 1933 to 1999, Macassa produced about 3.5 million ounces of gold from 7.9 million tons of ore. The head grade during that

period averaged 0.47 oz Au/ton and the recovered grade was 0.45 oz Au/ton.
Corporate History:
Macassa Mines Ltd. was incorporated in 1926 and evolved through a succession of mergers to become Lac Minerals Ltd. in 1982. The merger consolidated the properties of the Little Long Lac group into the one entity and the Macassa Mine and the other Kirkland Lake properties were included.
Lac Minerals was acquired by Barrick Gold Corporation in August 1994 and offered a number of Lac Minerals’ mineral properties for sale. Macassa was included but then withdrawn. After a short period of operation by Barrick the property was sold to Kinross in May 1995. Foxpoint purchased the Kirkland Lake properties of Kinross in December 2001. This purchase included the Macassa Mine and all of the plant.
Foxpoint changed its name to Kirkland Lake Gold Inc. in October 2002.
Kirkland Lake Gold Inc. prior to December 14, 2001 had interests in other mining properties but these were all abandoned or otherwise disposed of.
KLG purchased the mining assets that Kinross owned in and around Kirkland Lake for $5 million and the assumption of $2 million in reclamation bond obligations related to the closure plan for the properties. In addition Kinross will receive a NSR royalty from production. The purchase price was paid in installments and the purchase was completed in December 2003.
KLG restarted the Macassa mill in May 2002. The mill processed Lake Shore tailings at a rate of 880 tons per day. The grade of the tailings was 0.11 oz Au/ton and approximately 124 thousand tons were processed with gold recovery of 73%. An additional 45 thousand tons of surface rock from Lake Shore and the Teck-Hughes properties were also processed recovering 20,500 ounces of gold.
In December 2002 underground mining commenced.

GEOLOGY
The geology of the area and the property has been described in previous reports. The most recent reports were by GRCA in September 2005, by Sutton and Carmichael April 2004 and RPA in December 2002. The following brief geology descriptions are based on these reports and information gathered during the recent site visit.
Ridler in his report “Technical Report On Kirkland Lake Mineral Properties (Macassa Mine, Kirkland Lake Gold, Teck-Hughes, Lake Shore, Wright-Hargreaves), November 2001 has more details on the geology. KLG filed this report with Sedar and it is available atwww.sedar.com.
More reports on the geology are referenced in Appendix B.
Regional Geology:
The Kirkland Lake mining camp is located in the west portion of the Archean Abitibi greenstone belt of the Abitibi Subprovince that forms part of the Superior Province in the Precambrian Shield.
In the Kirkland Lake area the Abitibi Subprovince is composed of komatiitic, tholeiitic and calc-alkaline volcanics, turbidite-dominated sedimentary lithologies, locally distributed alkaline metavolcanic rocks and associated fluvial sedimentary form- ations. These successions have been intruded by tonalite, trondhjemite and granodiorite batholiths.
Large scale structures and tectonic fabrics are distributed in domains with rock foliations generally paralleling the regional faults, intrusive contacts and domain boundaries. The regional shear zones, folding and steep reverse faults post-date the batholith emplacement. Metamorphism of the Abitibi rocks is generally very low greenschist facies, however upper greenschist to hornblende facies may be attained in metamorphic aureoles surrounding intrusions.
Local Area Geology:
The Timiskaming Group of rocks is the main feature of the area. This Group forms part of a complex synclinorium that is flanked unconformably on the north and south by the mafic to felsic, massive to pillow volcanic rocks of the Kenojevis and Blake River groups. The Timiskaming Group is up to 10,500 feet thick

and extends for about 40 miles from Kenogami Lake in the west to the Quebec border. In the Kirkland Lake area, the Timiskaming is predominantly conglomerates and sandstones, trachytic lava flows and pyroclastic tuffs. The Timiskaming trends N65°E and dips steeply south at Kirkland Lake. Immediately east of Kirkland Lake, the formations are warped to an east-southeast direction and then return to an east-northeast direction at Larder Lake and continue this way to the Québec border.
The Timiskaming sediments are intruded by syenite porphyries and lamprophyre dykes and sills. Alkali stocks have intruded the Timiskaming Group and the supracrustal assemblage along the south margin of the synclinorium. Matachewan diabase dykes trending north-northeast cut all rocks in the area. (Figure 3)
The Kirkland Lake-Larder Lake Break, and its associated splay faults and fracture system, forms a complex, major structural feature which transects and follows the trend of the Timiskaming Group at Kirkland Lake. This Break can be traced for about 200 miles from Matachewan in the west of Kirkland Lake all the way to the Grenville Front east of Louvicourt, Quebec. As well as Kirkland Lake, it passes through or near the important mining areas of Larder Lake, Rouyn-Noranda, Cadillac, Malartic, Val d’Or and Louvicourt. Numerous gold occurrences and gold mines are spatially related to this regional structure.
The fault or break system that hosts the Kirkland Lake gold deposits is north of the main Kirkland Lake-Larder Lake Break. Polyphase deformation has affected the Timiskaming rocks at Kirkland Lake. The fold axes and structural plunges, including gold ore shoots, generally trend west-southwest at –60°.
Property Geology:
At the Macassa Mine the Timiskaming tuffs, conglomerates and the syenite porphyries are encountered. The syenites are the preferential hosts of the gold mineralization. Most of the mine workings are also in the syenites.
Gold Zones:
The gold mineralization at Macassa is found along breaks or faults, in veins as quartz filled fractures and as breccias.
There are a number of these breaks. They are named the ‘04’, ‘05’, No.6 Kirkland Lake Main and the Kirkland Lake North and South branches. The breaks trend about N60°E and dip steeply, 70° to 80° south in keeping with the Timiskaming trend.

At Macassa, the Kirkland Lake structures have been mined from 2,175 ft. to 6,955 ft. (660 m to 2,120 m) with the Main Break being the most important zone in the eastern part of the mine. The ‘04’ Break is in the western part of the property and is the main producing break at Macassa. It has been mined from the 4375 Level (1,330 m) to the bottom of the mine and it is known to continue deeper.
The ‘04’ Break is located about 600 ft. (185 m) north of the Main Break and connects to it by sigmoidal cross structures. The ‘04’ Break is a thrust or reverse fault striking N65ºE and dipping 80° to the south.
The No. 6 Break is a poorly defined, gold bearing major structure in the hanging wall of the ‘04’ Break that may represent the west continuation of the Main Break (South Branch).
The ‘05’ Break is located some 1,400 ft. (425 m) north of the ‘04’ Break. It splays into north and south branches to the east. The South Branch, about 1,200 ft. (365 m) north of the ‘04’ Break, appears to correlate with the Narrows Break that extends to the east across the rest of the camp.
The trend of the gold mineralization in the Kirkland Lake camp conforms to the 60º westerly plunge of the syenite intrusives. Locally the plunge of the gold mineralization depends on the intersection of the host splay structures and can be quite different from the camp trend.
According to Sutton the higher grade shoots constitute about 30% of the overall gold-mineralized structures cutting the syenites.
In addition to the mineral trends that have been historically productive, KLG has located significant mineralization to the south of these breaks. This mineralization is located in the “D” zone and the lower “D” zones that strike generally to the NE and dip at about 35° to the south. Other zones have been located to the south and the strike and dips of these zones is expected to be similar to the new “D” zones. The relative position of these zones can be seen in Figure 7.
Several strong northeasterly trending cross-faults offset the mine host rocks and mineralized zones with displacement usually to the south (dextral) and up on the west side. Major cross faults are the Tegren in the centre of the mine and the Amikougami Creek at the west end. The gold bearing zones have not been found west of the Amikougami Creek Fault.

Mineralization:
The gold mineralization is located along the breaks and subordinate splays as individual fracture fill quartz veins from several inches thick to as much as 12 ft. thick. Veins may be of single, sheeted or stacked morphology. Several generations of quartz deposition are evident from colour and textural variability and vein quartz is generally fractured.
The presence of a fault splay is often a prerequisite for gold deposition. Broader zones of mineralized brecciated and fragmented quartz are found in the footwall and hanging wall of major faults.
Gold is usually accompanied by 1% to 3% pyrite and sometimes is associated with molybdenite and/or tellurides of lead, gold, gold-silver, silver, nickel and mercury (altaite, calaverite, petzite, hessite, melanite, coloradoite). Silver is present both amalgamated with the gold and in the minerals petzite and hessite.
The presence of pyrite and silicification does not guarantee gold, however, higher grade gold is almost always accompanied by increased percentages of pyrite and silica.
Hematization or bleaching with carbonatization and silici- fication are commonly alterations of the wall rocks. Sericitization is a more local feature.
The alteration has enriched the rocks in K2O and depleted them in Na20.
The new discoveries to the South generally are of a different style of mineralization - wide sulphide systems rather than the quartz vein mineralization on the Main Break complex.
These new, wide, hydrothermally altered zones could represent a new plumbing system for a southern mineralized part of the Camp parallel to the Main Break, fed by a deep porphyry body. Mineralization in all of the holes to date on the Lower D (except 50-627) comprises carbonate altered conglomerate mineralized with up to 10% disseminated pyrite. The mineralization in hole 50-627 comprises porphyry-hosted quartz veining and silicification.

SAMPLING and ASSAYING
The Macassa Mine has an assay laboratory associated with the milling complex. This laboratory assays all of the mill samples, bullion and mine samples. The exploration samples from the drilling programs are sent to the Swastika Laboratory for analysis.
The sampling, handling and assaying methods used at KLG are consistent with good exploration and operational practices.
Sampling:
Diamond drill core samples, chip samples and muck samples are all used at Macassa for mining control as well as for reserve and resource determination.
Diamond drill holes are used to locate the extensions of the veins or to find new veins. Drill holes are also used to provide sample data between the mine levels for resource and reserve determinations. The drill core is logged in Macassa’a facility at the mine site. The core is oriented and marked for sampling by the geologist. For all exploration core (and some definition core), the intervals selected for sampling are cut in half by a diamond saw by the designated core splitter. One half of the core is retained in the core box for further consideration and the other is placed in properly marked sample bags for shipment to the laboratory. In the case of the exploration samples they are sent to the Swastika Lab. The collars of all diamond drill holes are surveyed and the holes are surveyed down the hole.
The chip samples are taken underground by a geologist or a by a trained sampler. Each new exposure of the veins is sampled in all of the workings. This is done by chipping with a hammer across the sample length in a channel fashion. The sample lengths are set so that the individual veins and the waste sections within the veins are sampled separately. The wall rocks at the sides of the veins are sampled separately from the veins. The samples seldom exceed 3.5 feet in length. The samples are placed in appropriately marked bags and transported to the laboratory. The samples are marked and located using the survey markers for control.
The muck samples are taken by the tram or mucking crews. A sample is to be taken from every car until about 20-25 tons of production is represented. These samples are reduced in size by riffling and placed in appropriately marked sample bags and
| Glenn R. Clark & Associates Ltd. | Page 27 |

transported to the laboratory. Muck sampling in Macassa, like in most mines, comes in and out of favour. Muck sampling had been discontinued at Macassa except for the long hole stopes where there is not any access for sampling between levels. Muck sampling of all the workings, development and stopes is now carried out for mining control.
Many of the pulps and rejects are sent out for analysis at commercial labs for a check on the quality of the assaying. Some of the exploration samples that go directly to a commercial lab are sent to another commercial lab for verification.
The program to send the samples out for check analysis is under the direction of Mr. Mike Sutton, P.Geo. of KLG.
Assaying:
The Macassa assay laboratory follows standard protocols for sample preparation and assaying. The lab includes standard samples, barren samples and a duplicate with each batch so that they can control the quality.
At the Macassa Laboratory the samples are
Crushed to 1/8 inch
Riffle split to a 200-250 gm sample
Pulverized with 90-95% passing 200 mesh screens.
The pulverizer and crusher are cleaned by compressed air after each sample.
Normal fire assay procedures are employed using either 1 assay ton for core or ½ assay ton for the other mine samples.
There are procedures in place for repeating the fusion if the button is too small or too large.
The silver is removed from the dore bead with nitric acid. The resulting gold prill is dissolved in aqua regia. MIBK extraction takes place before atomic absorption spectroscopy to determine the gold content. This is a fire assay with AA finish. If the grade is greater than 0.10 oz Au/ton then the fire assay is repeated and the gold prill is weighed on a microbalance giving the result as a fire assay with gravimetric finish.

Check Assaying:
The mine assaying is done at the KLG lab with check analysis at the Polymet lab. The exploration assaying is done at the Swastika lab. Each of these labs carries out internal check assaying and KLG arranges for check analysis between the lab.
This check assaying accounts for a lot of samples and for this study only the 4 months from November 2005 to February 2006 have been considered and the results are given below. A total of 628 samples were checked during this period.
The samples that are the most critical to the estimation of the grade of the resources are the samples with the values between 0.20 and 3.5 oz Au/ton.
It is not good enough to just average all of the samples and compare them as often there is an abundance of low grade samples that has a smoothing effect on the average of all the samples.
At Macassa, all values over 3.5 oz Au/ton are reduced to 3.5 oz Au/ton so the wide variations that can exist in high grade samples is not important as far as the assaying is concerned.
The values in the zones that are going to be mined are of great importance and the average results of the check assaying in the range from the cut-off up should be close if the sample size is sufficient.
The following are the averages for this set of check samples.

These are excellent results and give great confidence in the values that are used in the ore reserves and the day-to-day operation of the mine. The values in the critical range (shaded in blue) are very close even when the number of samples in the group is small. It can be expected that the higher values are more erratic and with a small number of samples in an assay group a wider variation would be expected.
All of the analysis can be found in Appendix D.

RESOURCES and RESERVES
Mining has been carried out at Macassa since 1933. The grade of the ore mined during that period is similar to the grade of the resources and reserves that are currently identified at Macassa. Most of the resources and reserves are associated with the “04” Break that has been the most productive at Macassa. KLG has located a new zone, the ‘D’ Zone that has added to the resources and reserves and the continuing exploration of this zone shows great promise. In the table below you will see that the production grades have been maintained over the years.
Table 5: Historical Production
| DECADEOF PRODUCTION | TONS X 1000 | GRADE,oz Au/ton |
| 1930’s | 564 | 0.48 |
| 1940’s | 1,087 | 0.45 |
| 1950’s | 1,440 | 0.40 |
| 1960’s | 1,290 | 0.48 |
| 1970’s | 943 | 0.56 |
| 1980’s | 1,314 | 0.49 |
| 1990’s | 1,294 | 0.47 |
| 2000’s | 291 | 0.35 |
| 1933 to 2005 | 8,223 | 0.47 |
During these many years of production the methods used for calculating the resources and reserves have evolved. The current method of calculation by KGL is quite similar to the methods employed for the last 25 years.
Each year the Macassa geology staff prepares a resource and reserve summary based on standard methods, with the criteria that have been developed over the years. The method of calculation and the results are discussed below. During the period that Lac Minerals was in control, most years the annual reserves were reviewed or audited by an independent engineer. This practice was not kept up under the guidance of Barrick and Kinross. A number of studies on grade capping and reserves and production reconciliation were carried out internally and by consultants for Lac Minerals and Kinross from the early 1990’s to the suspension of mining in 1999. In 2002, RPA reviewed the resources and reserves for KLG. In 2003 and 2004 the reserves were monitored by M. Sutton the Qualified Person (QP) for KLG in keeping with the directives of National Instrument 43-101 for technical reports. The resources and reserves were reviewed by GRCA in 2005.

Resource and reserve calculations are based on chip sampling of the veins and diamond drill hole results.
Macassa Resource and Reserve Calculations:
The Macassa Mine accounts for most of the resources and reserves that have been identified, however, included in the summary are some resources and reserves from the other KLG properties. The resources and reserves for the other properties were calculated by the Macassa Mine staff using the same criteria used for the Macassa Mine.
The resources and reserves have been classified to meet the requirements of NI 43-101.
National Instrument 43-101 Definitions of Resources and Reserves
The Reserve and Resource estimation classifications as prescribed in National Instrument 43-101 are given here for clarity.
MINERAL RESOURCE
Mineral Resources are sub-divided into 3 categories depending on the geological confidence. The highest level or the level with the most confidence is the ‘Measured’ category. The next level of confidence is the ‘Indicated’ category and the lowest level, or the resource with the least confidence, is the ‘Inferred’ category.
INFERRED MINERAL RESOURCE
An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling, gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
INDICATED MINERAL RESOURCE
An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade or quality, densities, shape
| Glenn R. Clark & Associates Ltd. | Page 32 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.
MEASURED MINERAL RESOURCE
A ‘Measured Mineral Resource’ is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.
MINERAL RESERVE
Mineral Reserves are sub-divided into 2 categories. The highest level of Reserves or the level with the most confidence is the ‘Proven’ category and the lower level of confidence of the Reserves is the ‘Probable’ category. Reserves are distinguished from resources as all of the technical and economic parameters have been applied and the estimated grade and tonnage of the resources should closely approximate the actual results of mining. The guidelines state “Mineral Reserves are inclusive of diluting material that will be mined in conjunction with the Mineral Reserves and delivered to the treatment plant or equivalent facility.” The guidelines also state that “The term ‘Mineral Reserve’ need not necessarily signify that extraction facilities are in place or operative or that all government approvals have been received. It does signify that there are reasonable expectations of such approvals.”
PROBABLE MINERAL RESERVE
A ‘Probable Mineral Reserve’ is the economically mineable part of an Indicated and in some circumstances a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining,
| Glenn R. Clark & Associates Ltd. | Page 33 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.
PROVEN MINERAL RESERVE
A ‘Proven Mineral Reserve’ is the economically mineable part of a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.
Macassa Mine Calculation Method:
BASIC INFORMATION
All of the assay data is plotted on plans and sections to be used for zone interpretations.
The ore reserves are calculated on 20 scale longitudinal sections or plan views in the case of veins dipping less than 45 degrees. Some calculations are done on 10 scale longitudinal sections using a modified polygon method of blocking.
Each stope area has a section or plan and a work sheet that is kept on file.
The calculated grade, zone width, area of influence and resource or reserve category for each data set (ie. drill hole or chip sample assays) is entered into a spread sheet. For reserves the expected dilution based on the assumed mining method is included. A separate page for each stope area is kept.
MINIMUM WIDTH
The minimum mining width for steep-dipping structures is 5 feet.
The minimum mining height for flat structures is 6.5 ft.
MINIMUM STRIKE LENGTH
The minimum strike length for a block is 21 ft (3 sets of chip assays).
| Glenn R. Clark & Associates Ltd. | Page 34 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
AREAS OF INFLUENCE
The radius of influence from a sampled heading is 30 ft. for Measured Resource/Proven Reserve(MR/PR).
A MR/PR Block must be exposed by at least one drift and tested between drifts by drilling in a 25 to 30 ft. pattern. Where continuity is proven with the drilling, the intervening polygons that are based on the 25 to 30 ft. drill pattern may be considered as MR/PR blocks.
For an Indicated Resource/Probable Reserve (IR/PbR) block the radius of influence is an additional 50 ft. (30-80 feet from the data). This applies to blocks sampled on two sides by workings a maximum of 150 ft. apart where no drilling exists, or above and below a drift where drill hole spacing is greater than 100 ft. For blocks with only drilling, 50’ radius is used.
Inferred Resource blocks are an additional 50 feet from the IR/PR block (from 80 to 130 ft. from the data). This applies to blocks bounded on one side by a MR/PR or IR/PbR. Blocks on a proven mineralized trend that are drilled on a spacing of greater than 100 ft. are included as Inferred Resource.
Raises that have been bored are usually ignored in the calculations. Most of the raises are only 42-60” in diameter, and are not representative of the ore width.
Test hole, and drift muck data is not used for ore reserve calculations.
DENSITY OF ORE
The density or tonnage factor used to convert the volume of the blocks to tons is 11.7 cu ft/ton.
The South Zone and Lower D zone volumes were converted at a density of 11.5 cu ft/ton.
The density traditionally used in the camp was 12.0 cu ft/ton. There have been a number of studies that suggest that the traditional number was too high and consequently gave an understated tonnage. The difference in the tonnage estimate is only about 2.5% between the density used in the past and the current density being used. As this has been applied to all blocks the changed density does not affect the reserve grades.
Further density testing in 2005 and 2006 has confirmed the densities used in the resource and reserve calculations.

July 18, 2006
CUT-OFF GRADE
Cut-off grades of both 0.25 oz Au/ton and 0.30 oz Au/ton are used for resource and reserve calculations depending on the location and economics of the block. Generally a cut-off of 0.32 is required on a whole-block basis to achieve profitability. For mining or geotechnical reasons some sub-blocks below the cut-off may be included. Blocks that grade between 0.20 and the cut-off are classified as resource blocks.
The resources at the #2 Shaft are blocks greater than 0.25 oz/t.
CAPPING OF ASSAYS
Macassa used to use a more complex system for cutting assays than it does now. The capping system, currently in use, is based on a Kinross report by B. Davis (1995). It appears that this simpler single cap method gives much the same results as the old system. It is probably not the final answer. As new ore is found in different settings the capping procedure may need to be modified.
The effect of grade capping can only be truly examined when a large tonnage has been mined and the recovered gold can be compared with the forecast for that period.
Grade capping or cutting is necessary at Macassa.
Assays higher than 3.5 oz Au/ton are cut to 3.5 oz. This capping practice appears to be reasonable.
In the current resource and reserve there are some blocks that have been treated differently. In some older parts of the mine the old information only included an average of the vein sections and not the individual assays. In lieu of cutting of the assays the average grades for those areas was reduced by 10%. There is no other grade modification. This capping practice appears to be reasonable.
DILUTION OF RESERVES
The dilution applied to the reserves depends on the type of stope that is anticipated for the mining blocks. The dilution is added on a stope basis. All dilution is assigned a grade of 0.02 oz Au/ton.
The average dilution of the reserves at April 30, 2006 is 28%.
| Glenn R. Clark & Associates Ltd. | Page 36 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
Long hole stopes are diluted by 32-50%, mostly 32%.
Cut-and-fill stopes 5-7 feet wide are diluted 15-24%. Some of the narrower stopes are diluted by 32%.
Cut-and-fill stopes that are greater than 7 feet wide are diluted 10-15%.
The dilution factors are based on a comprehensive study by Barrick in 1994.
These dilution levels can be obtained with good mining plans and careful supervision of the miners.
Dilution has not been added to the resource blocks.
MINING RECOVERY
The recovery of the ore blocks is anticipated at 94.2% of the diluted reserve.
This figure has been applied to all of the reserve blocks but not to the resource blocks.
GOLD PRICE
The gold price used to establish the cut-off grades has been set at $584.41 Canadian. This is based on the average price for gold and the exchange rate in the past year. ($US490.00 and $US1.00= $C1.19)
April 30, 2006 Resource and Reserve:

The Proven and Probable Reserves are diluted and recoverable. There has been no dilution added to the Measured and Indicated Resources and no allowance for recovery has been made.
Discussion of Resources and Reserves:
The resource and reserve estimation by Macassa has been carefully done. The estimation procedures and the application of the procedures were reviewed by Glenn R. Clark. This involved reviewing the interpretation of many of the stopes and spot checking the calculations and the summaries. The
| Glenn R. Clark & Associates Ltd. | Page 40 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
classifications meet the requirement of National Instrument 43-101 classification of Resources and Reserves.
As was noted in tables 6 & 7, some of the resources and reserves are under restriction imposed by the Ministry of Labour. The restriction relates to the April 12, 1997 seismic episode when the shaft was damaged below the 5700 level. It is anticipated that the restrictions will be lifted when KLG presents a new plan for rehabilitating the shaft and then mining the reserves.
The deeper restricted mineralized zones were reclassified on April 30, 2005 including these deeper mineralized sections as reserves when appropriate. There are no major changes to the Resources and the Reserves for the period ending April 30, 2006.
The Shaft Zone or Shaft Pillar will not be mined until the end of the mining cycle for the No. 3 Shaft.
The true test of a reserve estimate is whether the exploitation of the resource closely matches the estimate that was made.
The reserve and resource grades are similar to the grades that have been mined over the years. The average reserve grade of 0.47 oz Au/ton is the same as the average head grade from 1933-2004. (see Table 5) It is highly likely that with careful mining and proper grade control the production will match the reserves.

Section 8
MACASSA MINING and PROCESSING
Mining and processing at Macassa has been carried out since 1933. The mineral extraction has been from underground stopes. The processing has been done on the property.
The Macassa Mine employs conventional drill and blast mining methods to extract the ore. Access to the mining areas is by shafts.
The ore is processed by conventional cyanide leaching with a carbon-in-pulp recovery system.
In the 12 month period ending April 2006, KLG mined and processed 156,688 tons at a grade of 0.38 oz Au/ton. This tonnage included 11,600 tons from a low grade stockpile that graded approximately 0.08 oz Au/ton. This production rate is less than KLG had planned as the rehabilitation and development has taken longer than anticipated.
The forecast for the production in the 12 month period to the end of April 2007 is 180,000 tons for an increased tonnage of 20%. This increased production should be achievable. The head grade is also expected to increase with a forecast grade of 0.44 oz Au/ton. This grade is almost 16% higher than the head grade in the previous 12 months. Like the tonnage the grade improvement should be achievable. The combined improvement will increase the gold production by 30-40%. KLG is planning on operating at the rate of 180,000 tons per year on a regular basis. Over the next few years the mill head grade is expected to increase slightly to 0.47 oz Au/ton from the 0.44 oz Au/ton that is forecast for the 12 months ending April 2007.
Gold recovery is forecast at approximately 77,500 ounces in the current year and increasing to approximately 82,000 as the grade increases in the next few years.
Mining Method:
Mining is by normal cut and fill or long hole methods.
The cut and fill is carried out conventionally with slushers in the stope or mechanized utilizing scoop trams.
The long hole blocks are accessed by Alimak driven or bored raises with sub-level drifts. The mucking is by remotely driven scoop trams.
| Glenn R. Clark & Associates Ltd. | Page 42 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
Level trains move the ore to the main ore passes for hoisting to surface.
All of the stopes are now being filled with paste backfill. Previously the stopes were filled with cemented rock fill.
These mining methods recover about 94% of the ore.
Accessing below the 5300 Level:
As was stated earlier, due to the shaft being damaged below the 5700 level the Ministry of Labour restricted mining to the area above the 5300 Level. This effectively sterilized a large part of the known resources at Macassa.
KLG has been working with Knight Piésold Ltd. a consulting firm to develop a plan to rehabilitate the shaft. This preliminary assessment of the viability of rehabilitating the Shaft between 5725 Level and the 6150 Level included an assessment of the most favourable position for a ramp that would be needed.
The comments, focused on the geomechanical considerations associated with the two excavations, are at the pre-feasibility stage. More detailed reviews are necessary.
The general plan that was put forward involves a ramp for access, some rehabilitation on the levels and rehabilitation of the shaft.
The estimated cost for this project is $8.6 million with a 20% contingency included.
It is anticipated that when KLG submits a request along with a detailed plan to the Ministry of Labour the restriction will be lifted. Probably the detailed plan will not only have to outline how the shaft will be rehabilitated but how the mining will proceed afterwards.
It was on the basis of this preliminary study that the deeper ore was classified as reserves in 2005.
Processing the Ore:
The company’s mill was built in 1988 with a modern larger mill replacing the older mill. Some modifications have taken place since then and the mill capacity now is 1500 tons of ore a day.
| Glenn R. Clark & Associates Ltd. | Page 43 |
Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
The ore at Macassa is treated by conventional means. These are crushing and grinding followed by cyanidation with the gold recovered from solution by the carbon-in-pulp technique. The bullion contains some silver.
Gold recovery has been good at Macassa. From 1933 to 2005 the average recovery was 94.9% . In the 20 year period from 1980 to 1999 the average recovery was 95.8% with the highest one year recovery being 96.97% . KLG had a recovery of 97.3% in 2004 and 97.6% in 2005.
KLG has forecast that recovery for fiscal 2007 (May 2006 to April 2007) will be 97%. This is an ambitious forecast, however previous experience at Macassa shows that it is quite possible to have recoveries in that order. The mill will have to have sufficient ore to maintain the operation at the optimum levels if this high rate of recovery is to be attained.
The mill will be able to process all of the ore that can be delivered from the mine.
Operating Cost:
KLG has estimated the operating cost for the 12 month period from May 2006 to April 2007 (fiscal 2007). This plan calls for milling an average of 515 tons per day totalling 180,000 tons for the 12 month Period. The average head grade is forecast at 0.44 oz Au/ton and a total of approximately 77,500 oz Au will be recovered.
The following information is based on the company’s forecast. These costs are been based on the current operating experience.
The total cash costs per ton milled is forecast at $261 per ton.
The total cash costs per ounce milled is $368.
Based on a gold price of $584 per ounce, a recovery of 97% and the forecast cash operating cost per ton of $170 the cut-off grade is 0.30 oz au/ton.

Capital Costs:
The capital costs for the 12 month period ending April 2007 is estimated at $15.6 million. Included in this cost is $6.0 million for exploration.
The capital costs are expected to decrease over the next few years. In fiscal 2008 the exploration is expected to reduce to $1.8 million and the capital equipment requirements will alos reduce with the total capital costs for 2008 being only $9.6 million. The capital costs are expected to reduce further and by 2011 the capital costs are forecast at $6.4 million.

EXPLORATION
KLG is actively exploring the Kirkland Lake properties to extend the known zones and find new ones. This is a 3 year $21 million program that has located some interesting gold zones. The target areas are the Main Break,Parallel Breaks and North South structures, such as the Lower D Zone, on the Company’s land holdings. (Figure 5)
This exploration is mostly being done by diamond drilling from surface and from underground.
Development headings are driven to give properly located drilling stations. The development headings are also driven to access the mineralization that has been found and to confirm its nature.
This exploration has lead to the “D” Zone that is now part of the reserves.
KLG will continue exploring their properties. This recent find and other finds that KLG has made indicate the potential of the area.
Significant New Finds:
In a press release on July 11, 2005 KLG highlighted an intersection of 90.4 feet assaying 2.3 ounces uncut from Drill Hole 50-627.
As this intersection was 1765 feet from the collar of the hole it was decided to wedge the hole and have a second confirmatory cut of this new zone. (Figure 6)
A press release on August 15, 2005 gave the excellent results of the wedged hole. The wedged intersection intersected 1.43 oz Au/ton over 124.5 feet. The cut grade would be 0.84 oz Au/ton. The wedged hole intersected the new discovery 49 feet vertically above and 140 feet up-dip from the discovery hole, Hole 50-627. The mineralization intersected in the wedged hole is identical to the discovery, however considerably more visible gold and tellurides were observed in the wedged hole.
These intersections are located 1,600 feet south of the active mine workings at the Company’s #3 shaft.

Since these initial holes in the New South Zone KLG has continued drilling with good results. I had an opportunity to examine the core from some of these holes. The intersections are certainly impressive.
A drift, the 5300 Exploration Drift, was started in 2005 to access the New South Zone and it is anticipated that the zone will be accessed at the end of the 2006 when the drift is about 2300 feet long. At the end of June the drift has been driven 1400 feet or more than half way to its target. The drilling has also intersected other zones as can be seen in Figure 6 and the drift has intersected some of these zones confirming the results from the drilling. The location of the New South zone relative to the other zones can be seen in the oblique view of the veins in Figure 7.
When the new 5300 exploration drift was driven 650 feet to the south drill bays were completed and closer spaced drilling at 100 foot centers utilizing smaller air machines on the Lower D Zone commenced. This program is designed to both convert inferred resources to indicated resources and further expand the Lower D Zone north. Of 5 holes completed, 4 returned ore-grade intersections representing an 80% hit ratio, including 1.10 ounces of gold per ton over 18.0 feet core length (Uncut, true width=11.5 feet). At it’s closest point known to date, the Lower D Zone is located 1200 feet south of the operational workings on the 5025 level, and the #6 Splay is 900 feet to the south. At the 5025 level, the Lower D is now known to be virtually continuous ore for 1050 feet, followed by a further 850 feet of unexplored distance to the next drill hole that is also ore grade. The 60% intersection success overall on the Lower D Zone is especially gratifying and will serve KLG well as it continues to expand the Zone and the other mineralized systems south of #3 shaft.
Plans are underway to advance a new drift on the 5025 level in fiscal 2007. This will allow for the mining of the Lower D and #6 splay. The new discoveries to the South generally are of a different style of mineralization - wide sulphide systems rather than the quartz vein mineralization on the Main Break complex.
As well as having a different style of mineralization (wide sulphide system) they have a different orientation that is roughly perpendicular to the east-west mineralization but with a flatter dip than the main zones from which 24 million ounces of gold have been mined to date from the area. The dimensions at this time indicate the New South Zone has a potential dip component of 1,300 feet between the -5100 and -5500 elevations, and a strike component of 500 feet. The LK Zone discovery hole 45-911A, which intersected 26.21 ounces of gold uncut per ton (or 1.43 ounces per ton cut) over a core length of 6.0 feet,

appears to be an extension of the new discovery, adding an additional 200 feet of potential strike length.
To date, fourteen mineralized zones have been identified south of the mine workings, eight of which are in the area encompassing the New South/LK Zone.
The new, wide, hydrothermally altered zones could represent a new plumbing system for a southern mineralized part of the Camp parallel to the Main Break, fed by a deep porphyry body. Mineralization in all of the holes to date on the Lower D (except 50-627) comprises carbonate altered conglomerate min- eralized with up to 10% disseminated pyrite. The mineralization in hole 50-627 comprises porphyry-hosted quartz veining and silicification.
Multiple similarly mineralized zones of ore grade mineralization have been discovered in an area extending 600 feet to 2,200 feet south and 2,600 feet horizontal from the main source of ore for the Kirkland Lake ore body. The significant intersections to date are located between the -4800 and -5300 elevations and represent the most extensive series of north-south mineralized systems discovered yet.
There is great exploration potential as there is no drilling between surface and the new discoveries (a mile below). There is a strong possibility for additional parallel and stacked zones both above and below the new zones.
In house, metallurgical testing on core samples submitted from the New South Zone indicates that a 96.2% recovery may be achieved by using standard milling procedures.
The true significance of this find and the other zones that have been identified will only be known after considerable exploration has been carried out and the potential size and grade can be more realistically evaluated.
The company is planning on drilling more holes to extend these zones along strike.
Exploration on other zones is also continuing, especially in the upper parts of the mine.

Section 10
CONCLUSIONS and RECOMMENDATIONS
Conclusions:
The Resources and Reserves estimates truly reflect the mineralization that is currently known. The estimates conform to the requirements of National Instrument 43-101.
In general the development and exploration program initiated by KLG should continue.
Increased exploration and development underground is necessary to establish sufficient working faces to allow flexibility in the mining sequence. More working faces will allow the rate of production to rise without sacrificing the mill head grade.
Increased tonnage to the mill will allow it to operate at the optimum level.
Recommendations:
There are two parameters in the Resource estimation that need to be monitored and modified if indicated.
1: The first is the assay capping or cutting. This can have a larger effect on the resources than the density. The capping of assays is an important part of the Resource estimations. There are a number of ways to establish the cap method and the method used by Macassa appears to be sufficient at present. However, it is known that all zones are not the same and the cap for one zone may not be proper for another zone. Changing mineralization or even the size and distribution of the gold will affect the necessary capping level.
It may prove worthwhile to compare the mined tonnages and grades of the stopes with the basic data that the Resource estimate was made from.
For the new zones that have not been mined it will be important to consider the assays and the mineral distribution before a cutting factor is established.
2: The second is the dilution. Dilution affects the Reserves more than any change that one could foresee from the density or the assay capping. Every effort should be made to monitor the dilution. This monitoring is important so the proper dilution can be applied to the Reserve estimations.

Macassa Mine, Kirkland Lake Gold Inc.
July 18, 2006
More importantly, dilution is expensive and by monitoring the dilution it may be possible to recognize the reason and rectify it with a change in the mining practice.
This is a constant problem and the geology department and the mining department have to work together on this problem.
