PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. This summary may not contain all of the information that you should consider before investing in our common stock. We urge you to read this entire prospectus supplement, the accompanying prospectus and the documents incorporated by reference carefully, including the section entitled “Risk Factors” and the financial statements and other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus.

Overview

The Company is a producing, Nevada-based, gold and silver mining company with extensive, contiguous property in the historic Comstock and Silver City mining districts (collectively, the “Comstock District”). The Comstock District is located within the western portion of the Basin and Range Providence of Nevada, between Reno and Carson City. The Company was incorporated in Florida in 1999 and reincorporated in Nevada in 2008. The Company began acquiring properties and developing projects in the Comstock District in 2003. Since then, the Company has consolidated a substantial portion of the Comstock District, secured permits, built an infrastructure and brought exploration projects into production.

Because of the Comstock District’s historical significance, the geology is well known and has been extensively studied by the Company, our advisors and many independent researchers. We have expanded our understanding of the geology of the project area through vigorous surface mapping and drill hole logging. The volume of geologic data is immense, and thus far the reliability has been excellent, particularly in the various Lucerne Mine areas. We have amassed a large library of historic data and detailed surface mapping of Comstock District properties and continue to obtain historic information from private and public sources. We use such data in conjunction with information obtained from our current mining operations to target geological prospective exploration areas and plan exploratory drilling programs.

Our Lucerne Resource area is located in Storey County, Nevada, approximately three miles south of Virginia City and 30 miles southeast of Reno. Our Dayton Resource area, is located in Lyon County, Nevada, approximately six miles south of Virginia City. Access to the properties is by State Route 342, a paved highway.

Our business plan is to deliver stockholder value by validating qualified resources (measured and indicated) and reserves (proven and probable) of at least 3,250,000 gold equivalent ounces from our first two resource areas, Lucerne and Dayton; and significantly grow the commercial development of our operations through coordinated, district wide plans that are economically feasible and socially responsible.

The Company has already met the first three intermediate resource validation objectives by validating measured and indicated resources containing more than 2,100,000 gold equivalent ounces.

The Company has developed a mine plan intended to achieve initial commercial mining and processing operations in the Lucerne Mine and annual production rates of approximately 40,000 gold equivalent ounces. The Company achieved initial production and held its first pour of gold and silver on September 29, 2012 and produced more than 20,000 gold equivalent ounces in 2013, its first full year of production from this recent start up.

The Company continues acquiring additional properties in the Comstock District, expanding its footprint and creating opportunities for exploration and mining. The Company now owns or controls approximately 7,447 acres of mining claims and parcels in the Comstock and Silver City Districts. The acreage is comprised of 1,376 acres of patented claims (private lands) and surface parcels (private lands) and 6,071 acres of unpatented mining claims, that are administered by the Bureau of Land Management (“BLM”).

The Company’s hospitality segment owns and operates the Gold Hill Hotel and related cottages. The hospitality segment is not generally seasonal in nature except for the period November through February when tourism population volumes are commonly lower.

Financial information for each of our segments is disclosed in footnote 15 to our consolidated financial statements in the 2013 Form 10-K.

Current Projects

The Company’s headquarters, mine operations and heap leach processing facility are in Storey County, Nevada, at 1200 American Flat Road, approximately three miles south of Virginia City, Nevada and 30 miles southeast of Reno, Nevada. The Company has focused to date on the Lucerne Resource area (including the east-side target within this area), the Dayton Resource area and the Spring Valley exploration target. We also plan on focusing exploration on the Northern Extension, Northern Targets, and Occidental Target areas subsequent to the exploration and development of Lucerne, Dayton and Spring Valley. The Company’s existing heap leach processing facility for gold and silver was redesigned and expanded in late 2013 to accommodate expanded production plans.

The Lucerne Resource area has been the focus of the Company’s exploration and development efforts since 2007. It includes the previously mined Billie the Kid, Hartford and Lucerne mining claims, and extends north to the historic Justice and Keystone mines and northeasterly to the area of the historic Woodville bonanza. The Company has the key mining permits required for this area. The Lucerne Resource area is approximately 5,000 feet long, with an average width of 600 feet, representing less than three percent of the land holdings controlled by the Company and is the site of our current production activities. The east-side target within this area ranks as one of the Company’s top exploration and production expansion targets for late 2014.

The Dayton Resource area is southwest of Silver City in Lyon County, Nevada. It generally includes the Dayton, Kossuth and Alhambra claims, including the old Dayton mine workings, south to where the Kossuth claim crosses State Route 341. The historic Dayton mine was the last major underground mining operation in the Comstock District, before being closed after the War Production Board promulgated Limitation Order L-208, 7 F. R. 7992 on October 8, 1942, that closed down all gold mining operations in the United States and its territories. The Dayton Resource area ranks as one of the Company’s top exploration and potential mine production targets. Recently, the Lyon County Board of Commissioners approved a strategic master plan and zoning changes on the Dayton, Kossuth and Alhambra mining claims and other properties located in the Dayton Resource Area, enabling a more practical, comprehensive feasibility study for mining.

The Spring Valley exploration target lies at the southern end of the Comstock District, where the mineralized structures lie mostly concealed beneath a veneer of sediment gravels. The area includes the Kossuth claim south of State Route 341, the Dondero property, the New Daney lode mining claims, and the Company’s placer mining claims in Spring Valley and Gold Canyon.

The Northern Extension, Northern Targets and Occidental areas represent exploration target areas that contain many historic mining operations, including the Overman, Con Imperial, Caledonia, and Yellow Jacket mines, among others. Previous operators have explored the various mines in this area, some of which have led to mineralized material inventories. We believe that our consolidation of the Comstock District has provided us with opportunities to utilize the historical information available to identify drilling targets with significant potential.

Exploration

Drill Program (Lucerne Resource Area)

In the Spring of 2013, the Company approved specific drilled locations along the west side of State Route 342 within the current Lucerne Resource area including, from south to north, The Billie the Kid, Lucerne, Justice and Keystone mine areas. The areas are located within the current mine plan and after reviewing the geologic sections, the decision was made to drill additional Reverse Circulation (RC) holes to confirm projected mineralization and collect material for additional metallurgical study. The drilling did confirm the predicted geological structures, elevations and extents of mineralization. The metallurgical studies enhanced our understanding of predicted recoveries compared to prior metallurgical analysis. The drilling and metallurgical studies (including electron micro-probe) found no evidence of reactive sulfide mineralization and no other mineralogical properties that would negatively affect the recoveries from our cyanide heap leach operation. The 2013 drilling program (the “Drill Program”) included a total of 22 drill holes and 4,065 feet. For Billie the Kid; we drilled six holes with an average depth of 340 feet. For Lucerne, we drilled thirteen holes with an average depth of 120 feet. For Justice, we drilled six holes with an average depth of 160 feet and for Keystone we only drilled one well-positioned hole down to 120 feet. The Drill Program was defined for specific information and collected information that confirmed predicted geologic and attributes and metallurgical properties.

Kentuck Drill Program

In the fall of 2013, the Company conducted a second more narrowly scoped drill program at the Kentuck mine dump ("Kentuck Program"). The Kentuck Program evaluated certain mine dump material located on Sutro Mining Co. lands. The mine dump was waste rock from historic mining on the Kentuck. The area tested was approximately 100 feet by 250 feet. The drill holes were arranged in a grid pattern that included 116 drill holes. The drill holes ranged from 20 feet to 60 feet, with an average depth of 24 feet.

On-Going Drill Programs

The Company’s continues to evaluate high priority targets, including in the nearer term, the East Side of the Lucerne and Dayton Resource Areas and also the Spring Valley Target Area. Future programs would include the Occidental, Oest and the Northern Target areas.

The proposed evaluation of the East Side Target areas includes continuing infill drilling, metallurgical testing and geotechnical analysis to confirm the mineral potential and expand the mine plan on the East Side of State Route 342. In addition, the Company is designing a new phase of exploration drilling to include its highest-potential targets, including scoping studies of the Chute Zone in the Lucerne Resource area and plans for expanded exploration and development drilling in the Dayton Resource area that will allow for proper mineral assessment and mine plan development. The drill program is currently being expanded with approximately 100,000 feet of reverse circulation and 20,000 feet of core drilling, for both Lucerne and Dayton, planned at an investment of approximately $7 million.

The Company completed a successful phase of exploration drilling in Spring Valley in 2012. The drilling in the northern portion of Spring Valley was partially predicated to confirm buried mineralization by drilling specific magnetic geophysical anomalies that had similar magnetic signatures as defined by mineralized drill holes, drilled prior to the geophysical surface survey. The drill program is currently being expanded to test the full extent of the geophysical target with approximately 35,000 feet of reverse circulation and 5,000 feet of core drilling planned at an investment of approximately $2 million.

The total 2014-2015, drilling programs, including Lucerne, Dayton and Spring Valley would represent approximately 135,000 feet of reverse circulation drilling, and approximately 25,000 feet of core drilling at a total investment of approximately $9 million. The drilling would be planned to start in the latter half of 2014.

Production

During 2013, the Company completed the ramp up and stabilization activities of the production system, including significant improvements to the metal extraction processes, particularly in the Merrill-Crowe facility. We invested approximately $1.5 million for certain productivity enhancing actions associated with pump, pipe, filtration and press capacities, so the Merrill-Crowe and heap leach facilities could operate at fluid processing rates of over 1,000 gallons per minute. For substantially all of 2013, we were processing only 1.0 million tons of ore per annum due to a permit limitation. This limitation was unblocked during the fourth quarter when major modifications of our permits were approved. Accordingly, we surpassed our 2013 revenue guidance, exceeding the estimated 20,000 gold equivalent ounces, and producing over 20,800 gold equivalent ounces during the Company’s first full year of production.

On November 12, 2013, the Company received a major modification to its water pollution control permit, increasing our authorized capacity and our processing rate from a previous maximum of 1.0 million tons per annum to 4.0 million tons per annum. In December 2013, the Company completed the construction of two new leach pad cells and the supporting ponds and related infrastructure. The system is now operational and materials are being stacked, leached and processed. Our first five existing cells continue under solution, as typical, until the target gold and silver recovery rates have been achieved.

The completed expansion and improvements represent the next major phase of growth for the Company, enabling production growth of 100%, with the goal of reducing unit costs and increasing cash flow. The Company plans to exceed a production rate of 40,000 gold equivalent ounces in 2014.

The Company averaged over 400 gold-equivalent ounces poured per week in 2013. The Company continuously adjusted its operations to improve grade, maximize yields and increase tons crushed and stacked throughout 2013, and averaged over 500 gold-equivalent ounces poured per week throughout the second half of 2013. Overall during 2013, the Company crushed and stacked 1,072,000 dry tons of mineralized material, delivering 22,192 estimated ounces of recoverable gold and 396,082 estimated ounces of recoverable silver to the leach pads, positioning the Company well for growth. Material placed on the heap leach pads remains under solution until the target recovery rates are achieved. Throughout this period, the recovery of gold and silver continues, but the most effective economic recovery of gold and silver takes between 45 to 60 days to complete. The Company has recovered 68% of the estimated recoverable gold and 48% of the estimated recoverable silver from the portion of the heap under leach the longest. Preliminary laboratory metallurgical test results suggest that ultimate heap leach recovery will meet or exceed the estimated ounces of recoverable gold and silver.

For the quarter ended December 31, 2013, the Company realized an average sales price of $1,324.29 per ounce of gold and $20.68 per ounce of silver. In comparison, commodity market prices averaged $1,272.47 per ounce of gold and $20.76 per ounce of silver.

For the year ended December 31, 2013, the Company realized an average sales price of $1,361.70 per ounce of gold and $21.97 per ounce of silver. In comparison, commodity market prices in 2013 averaged $1,411.03 per ounce of gold and $23.83 per ounce of silver.

For the first quarter of 2014, the Company poured 4,546 ounces of gold and 49,292 ounces of silver, as compared to 2,261 ounces of gold and 15,599 ounces of silver in the first quarter of 2013, an increase of over 100% for gold ounces produced and over 215% for silver ounces produced when compared to the comparable quarter in 2013. The Company mined approximately 950,000 tons of material (mineralized material and waste) as it continued transitioning into higher-grade segments of the mine plan while expeditiously moving through some higher stripping ratios. Total mineralized material delivered to the leach pad was over 205,000 tons and represented some of the highest gold and silver grades crushed to date. The weighted average for the quarter was .024 ounces per ton gold and .345 ounces per ton silver, with an average in the month of March 2014 exceeding .034 ounces of gold per ton and over .50 ounces of silver per ton.

S-4

The Company averaged over 409 gold equivalent ounces poured per week in the first quarter of 2014. During the quarter ended March 31, 2014, the Company crushed and stacked approximately 205,686 dry tons of mineralized material. Throughout this period, the recovery of gold and silver continues, but the most effective economic recovery of gold and silver takes between 45 to 60 days to complete. The Company has recovered 70% of the estimated recoverable gold and 48% of the estimated recoverable silver from the portion of the heap under leach the longest. Preliminary laboratory metallurgical test results suggest that ultimate heap leach recovery will meet or exceed the estimated ounces of recoverable gold and silver.

Throughout the first three months of 2014, the Company realized an average price of $1,251.39 price per ounce of gold and a $20.73 average sales price per ounce of silver. In comparison, commodity market prices in the first three months of 2014 averaged $1,293.67 per ounce of gold and $20.49 per ounce of silver.

Our Comstock exploration activities include open pit gold and silver test mining. As defined by the Securities Exchange Commission (“SEC”) Industry Guide 7, we have not yet established any proven or probable reserves at our Comstock Lode Project.

Operating Costs

During 2013, actual Lucerne Mine costs applicable to mining revenue were $26.5 million, net of silver by-product credits. Cost applicable to mining revenue include mining and processing labor, maintenance, drilling and blasting and assaying costs associated with higher production rates and higher absorbed inventory costs incurred in advance of achieving the targeted production rate.

Costs applicable to mining revenue for the twelve months of 2013 include $1 million of higher hauling costs, including the previously incurred redundancy associated with our inability to use an existing haul road that crosses Lot 51 for most of the first quarter, and the transition costs associated with renting new haul vehicles while transitioning out of the existing, temporary vehicles. Costs applicable to mining revenue also include $4.7 million of depreciation and a $1.5 million write-down of inventory to market value during 2013. Management believes the system is now capable of operating at twice the production rates of 2013 and is ramping up operations to those higher levels during the first quarter of 2014, now that final applicable permits have been approved.

During the third and fourth quarters, once production had stabilized, the Company continued focusing on stream-lining the organization and reducing general, administrative, consulting and other related costs. The Company has also focused on reducing costs applicable to mining and leveraging the existing fixed operating expenses for the production of higher ounces in the latter part of 2014. Costs applicable to mining, dropped sequentially, on a per ounce basis, every quarter during the year. Once stabilized at the 40,000 ounce per annum run rate, the Company expects cash costs per ounce of gold mined of less than $750. 

During the first three months of 2014, actual Lucerne Mine costs applicable to mining revenue were approximately $5.8 million, $4.8 million net of silver credits. Cost applicable to mining revenue include mining and processing labor, maintenance, drilling and blasting and assaying costs associated with higher production rates and higher absorbed inventory costing associated with costs incurred in advance of achieving the targeted production rate, including the planned increases in 2014. Costs applicable to mining revenue for the first three months of 2014, also include $1.3 million of depreciation.

During the first quarter, the Company continued reducing costs applicable to mining, targeting over $6 million in reductions for 2014, as compared to 2013. The Company has already realized annual savings of approximately $1 million from reduced staffing in crushing, related maintenance, mining and administrative cost reductions with further opportunities in drilling, blasting, logistics and administration. Costs applicable to mining have been reduced over the past five quarters, with first quarter costs of sales, on a cost per ounce basis, at the lowest since inception, at slightly over $1,000 per ounce.

S-5

2014 Outlook

Through the end of 2013, the Company began transitioning into production at higher rates and grades with lower sustainable costs. The recently acquired permit now allows processing rates of up to 4 million tons of mineralized material to be placed on the leach pad per annum and the Compnay's 214 business plan calls for processing and shipping at a rate of 40,000 gold equivalent ounces. Two additional cells were constructed in 2013 and stacking on these cells has already commenced. The Company is also fully permitted to add an additional cell when needed.

Under our current mine plan, we anticipate doubling the rate of ounces produced when compared to 2013, for both gold and silver, targeting a production rate of 40,000 gold equivalent ounces in 2014. These increases come with lower costs applicable to mining due to focused cost reduction efforts, as well as lower non-mining operating expenses. Once stabilized at the 40,000 ounce per annum run rate, the operating expenses per ounce mined will be significantly lower. The Company expects cash costs per ounce of gold mined of less than $750 per ounce. The Company updated its financial analysis for the Lucerne Mine and anticipates annual operating expenses, including all mining and processing costs, of less than $25 million per annum, a more than a $6 million reduction over prior year 2013. The Company has also identified $3.5 million of cost reductions in all other non-mining activities, including general, administrative and environmental areas.

Recent Developments

Subsequent to December 31, 2013, the Company entered into an agreement to purchase 78 Acres in American Flat, Storey County, Nevada for $1,107,000. The purchase price includes $10,000 cash and the remaining amount in Company restricted common stock. Escrow is expected to close on or before December 25, 2014.

Subsequent to December 31, 2013, the Company entered into an agreement to purchase buildings and mining claims adjacent to its processing facility on American Flat Road, Storey County, Nevada for $893,000. The purchase price includes $10,000 cash and the remaining amount in Company restricted common stock. Escrow is expected to close on or before February 25, 2015.

Subsequent to March 31, 2013, the Company entered into an agreement to purchase a building located near its mine offices in Gold Hill, Storey County, Nevada for $400,000. The purchase price includes $25,000 cash and the remaining amount in Company restricted common stock. Escrow is expected to close on or before November 2, 2015.

On February 11, 2014, the Company entered into a new, lower cost $5 million revolving credit facility (the “Revolving Credit Facility”) with Auramet International, LLC, pursuant to which the Company may borrow up to $5 million outstanding at any one time. The proceeds of the Revolving Credit Facility will be used for working capital, including production ramp up and preparations for expansion of the Lucerne Mine, including targeted drilling on the east side of the Lucerne Resource area. Interest is payable at 9.5% per annum, and was paid in advance on the closing date of the Revolving Credit Facility. The indebtedness under the Revolving Credit Facility is secured by a security interest in certain real estate owned by the Company within the Company’s starter mine and a first priority security interest in all personal property of the Company and its wholly-owned subsidiary Comstock Mining LLC, subject to any existing or future Permitted Liens (as defined under the Revolving Credit Facility). Provided that no default has occurred and is continuing, and the Company has already repaid the principal amount of borrowings under the Revolving Credit Facility in an amount of not less than $1,000,000, the Company has the option until October 6, 2014 to re-borrow funds under the Revolving Credit Facility. The Revolving Credit Facility contains a covenant that requires the Company to maintain a minimum liquidity balance of $1 million (including cash and cash equivalents, plus 90% of the value of any doré that has been picked up by a secured carrier but not yet paid for, as of any date of determination). The Revolving Credit Facility additionally contains customary representations, warranties, affirmative covenants, negative covenants, and events of default, as well as conditions to borrowings. On February 12, 2014, the Company drew down proceeds of approximately $4.6 million.

On April 10, 2014, the Company announced an update on its progress for 2014, mine operations, cost reductions and organization.  For the first quarter of 2014, the Company poured 4,546 ounces of gold and 49,292 ounces of silver, as compared to 2,261 ounces of gold and 15,599 ounces of silver in the first quarter of 2013, an increase of 100% for gold ounces produced and over 215% for silver ounces produced when compared to the comparable quarter in 2013.  The Company mined approximately 950,000 tons of material (mineralized material and waste) as it continued transitioning into higher-grade segments of the mine plan while expeditiously moving through some higher stripping ratios.  Total mineralized material delivered to the leach pad was over 205,000 tons and represented some of the highest gold and silver grades crushed to date.  The weighted average for the quarter was .024 ounces per ton gold and .345 ounces per ton silver, with March 2014 averaging over .034 ounces of gold per ton and over .50 ounces of silver per ton. 

The Company continues reducing costs applicable to mining, targeting over $6 million in reductions for 2014, as compared to 2013.  The Company has already realized annual savings of approximately $1 million from reduced staffing in crushing, related maintenance, mining and administrative cost reductions with further opportunities in drilling, blasting, logistics and administration.  For example, the Company saved nearly 154,000-kilowatt hours per annum participating in NV Energy's Sure Bet Incentive Program.  Costs applicable to mining has been reduced over the past five quarters, with first quarter 2014 costs of sales, on a cost per ounce basis, at the lowest since inception, at slightly over $1,034 per ounce.

In July 2012, the Company placed a $4.67 million reclamation surety bond, through the Lexon Surety Group with the State of Nevada’s Bureau of Mining Regulation Reclamation. Effective December 19, 2013, the surety bond was increased to $5.20 million and on April, 11, 2014, the surety bond was increased to $6.35 million. The bond insures for the estimated costs required to safely reclaim the natural environment to the regulatory standards established by the State of Nevada’s Division of Environmental Protection with the purposes of ensuring public safety, protecting the waters of the state, and providing for post-mining land use.

RISK FACTORS

Investing in our common stock involves significant risk. Prior to making a decision about investing in our common stock, you should carefully consider the specific risk factors included below, as well as the risk factors discussed under the heading “Risk Factors” in the 2013 Form 10-K, which is incorporated by reference in this prospectus supplement and the accompanying prospectus and may be amended, supplemented or superseded from time to time by other reports we file with the Commission in the future. The risks and uncertainties we have described are not the only ones we may face. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also affect our operations. If any of these risks actually occurs, our business, results of operations and financial condition could suffer. In that case, the trading price of our common stock decline, and you could lose all or a part of your investment.

Risks Relating to the Company’s Common Stock and this Offering

You may lose all or part of your investment.

If we are unable to find and mine adequate quantities of gold and silver ore, it is unlikely that the cash generated from our internal operations will suffice as a primary source of the liquidity necessary for anticipated working capital requirements. There is no assurance that the Company’s initiatives to improve its liquidity and financial position will be successful. Accordingly, there is substantial risk that the Company will be unable to continue as a going concern. In the event of insolvency, liquidation, reorganization, dissolution or other winding up of the Company, the Company’s creditors and preferred stockholders would be entitled to payment in full out of the Company’s assets before holders of common stock would be entitled to any payment and the claims on such assets may exceed the value of such assets.

Restrictions imposed by the terms of the Company’s preferred stock may inhibit growth.

The certificates of designation of our preferred stock substantially limit the ability of the Company to incur debt or redeem capital stock or pay dividends to common shareholders among other things. Such restrictions could significantly impact the Company’s ability to go into production and generate cash flows.

You will be a minority stockholder of the Company.

Prior to the completion of this Offering, including its ownership of preferred shares and warrants of the Company, the Winfield Group owns approximately 31.9% of the economic interests of the Company’s capital stock and approximately 68.4% of the voting security interests, in each case on an as converted basis. As a result, the ability of holders of common stock to determine the management and policies of the Company will be significantly limited.

The terms of the Operating Agreement of Northern Comstock LLC may significantly dilute your ownership interests.

The Operating Agreement of Northern Comstock LLC provides for capital contributions by the Company in the form of Series A-1 preferred stock, unless Northern Comstock LLC requests payment in cash. The Operating Agreement provides for additional capital contributions over 39 years and contributions of 862.5 shares of Series A-1 preferred stock would be made on the anniversary of the Operating Agreement each year, if no requests for contributions in cash were made. If an event of default occurs under the Operating Agreement, the additional capital contributions could be accelerated and the entire unpaid amount of the Company’s capital contributions, could become issuable immediately at the option of Northern Comstock LLC. The Company has made the first four scheduled capital contributions of 3,450 shares of Series A-1 convertible preferred stock (approximately 5.3 million shares of common stock as converted) with contributions of 31,050 shares of Series A-1 convertible preferred stock (approximately 48 million shares of common stock as converted) remaining. In addition, the Operating Agreement provides that each time more than 200,000 gold equivalent ounces of measured and indicated resources are validated, the capital contributions for such year will be accelerated to $5 million or 5,000 shares of Series A-1 preferred stock.

S-9

The Company may issue additional common stock or other equity securities in the future that could dilute the ownership interest of existing shareholders.

The Company is currently authorized to issue up to 3,950,000,000 shares of Common Stock, of which 74,198,711 shares were issued and outstanding as of May 8, 2014, and 50,000,000 shares of preferred stock, of which 48,985.5 shares of convertible preferred stock were issued and outstanding as of May 8, 2014. To maintain its capital at desired levels or to fund future growth, the Company’s board of directors may decide from time to time to issue additional shares of common stock, or securities convertible into, exchangeable for or representing rights to acquire shares of common stock. The sale of these securities may significantly dilute its shareholders’ ownership interest as a shareholder and the market price of the common stock. New investors in other equity securities issued by the Company in the future may also have rights, preferences and privileges senior to its current shareholders that may adversely impact its current shareholders.

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase.

Since the price per share of our common stock being offered is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. Based on the offering price of $ per share, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of approximately $ per share in the net tangible book value of the common stock. See the section entitled “Dilution” in this prospectus supplement for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering.

The price of the Company’s common stock may fluctuate significantly, which could negatively affect the Company and holders of its common stock.

The market price of the Company’s common stock may fluctuate significantly from time to time as a result of many factors, including:

·    investors’ perceptions of the Company’s and its prospects;

·    investors’ perceptions of the Company’s and/or the industry’s risk and return characteristics relative to other investment alternatives;

·    investors’ perceptions of the prospects of the mining and commodities markets;

·    differences between actual financial and operating results and those expected by investors and analysts;

·    our inability to commence production, obtain permits or otherwise fail to reach Company objectives;

·    actual or anticipated fluctuations in quarterly financial and operating results;

·    volatility in the equity securities market; and

·    sales, or anticipated sales, of large blocks of the Company’s common stock.

S-10

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. We do not currently have, and may never obtain, research coverage by securities and industry analysts. If no securities or industry analysts commence coverage of the Company, the trading price for our common stock would be negatively impacted. If we obtain securities or industry analyst coverage and if one or more of the analysts who cover us downgrades our common stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline.

We do not expect to pay any cash dividends for the foreseeable future.

We currently expect to retain all available funds and future earnings, if any, for use in the operation and growth of our business and do not anticipate paying any cash dividends in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board, subject to compliance with applicable law, our organizational documents (including the certificates of designations for our preferred stock, which prohibit cash dividends to common stockholders without the consent of preferred stockholders) and any contractual provisions, including under agreements for indebtedness we may incur, that restrict or limit our ability to pay dividends, and will depend upon, among other factors, our results of operations, financial condition, earnings, capital requirements and other factors that our Board deems relevant. Accordingly, if you purchase shares in this offering, realization of a gain on your investment will depend on the appreciation of the price of our common stock, which may never occur. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.

S-11

USE OF PROCEEDS

We estimate that the net proceeds we will receive from this offering will be approximately $ , based on the public offering price of $ per share, after deducting the underwriting discounts, commissions and estimated offering expenses of $ .

We currently intend to use the net proceeds from this offering to expand production and commence exploration and development drilling programs in the Lucerne and Dayton Resource Areas. We intend to use the remaining net proceeds from this offering for general corporate purposes.

Pending the application of the net proceeds as described above, we may invest the net proceeds from this offering in short-term, investment grade, interest-bearing securities.

DILUTION

Investors in shares of our common stock offered in this offering will experience an immediate dilution in the net tangible book value of their common stock from the public offering price of the common stock. The net tangible book value of our common stock as of March 31, 2014, was approximately $16.8 million, or approximately $0.23 per share of common stock. Net tangible book value per share of our common stock is calculated by subtracting our total liabilities from our total tangible assets (which is equal to total assets less intangible assets) and dividing this amount by the number of shares of common stock outstanding.

Dilution per share represents the difference between the public offering price per share of our common stock and the adjusted net tangible book value per share of our common stock included in this offering after giving effect to this offering. After giving effect to the sale of all of the securities offered in this offering at the offering price of $ per share, and after deducting the underwriters’ discounts estimated offering expenses payable by us, our as adjusted net tangible book value as of March 31, 2014, would have been approximately $ million, or approximately $ per share of common stock. This change represents an immediate increase in the net tangible book value of $ per share of common stock to our existing stockholders and an immediate and substantial dilution in net tangible book value of $ per share of common stock to new investors. The following table illustrates this per share dilution:

Offering price per share			$
Net tangible book value per share as of March 31, 2014	$	0.23
Increase in net tangible book value per share attributable to new investors	$
As adjusted net tangible book value per share as of March 31, 2014, after this offering			$
Dilution per share to new investors			$

The number of shares of common stock to be outstanding after the offering is based on 72,292,324 shares of common stock outstanding as of March 31, 2014.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following discussion is a general summary of material U.S. federal income tax considerations with respect to your acquisition, ownership and disposition of our common stock, and applies if you (1) purchase our common stock in this offering, (2) will hold the common stock as a capital asset and (3) are a “non-U.S. Holder.” You are a non-U.S. Holder if you are a beneficial owner of shares of our common stock other than:

·    a citizen or resident of the United States;

·    a corporation or other entity taxable as a corporation created or organized in, or under the laws of, the United States, any state thereof or the District of Columbia;

·    an estate, the income of which is subject to U.S. federal income taxation regardless of its source;

·    a trust, if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust; or

·    a trust that has a valid election in place to be treated as a U.S. person for U.S. federal income tax purposes.

This summary does not address all of the U.S. federal income tax considerations that may be relevant to you in the light of your particular circumstances or if you are a beneficial owner subject to special treatment under U.S. federal income tax laws (such as if you are a controlled foreign corporation, passive foreign investment company, company that accumulates earnings to avoid U.S. federal income tax, foreign tax-exempt organization, financial institution, broker or dealer in securities, insurance company, regulated investment company, real estate investment trust, person who holds our common stock as part of a hedging or conversion transaction or as part of a short-sale or straddle, U.S. expatriate, former long-term permanent resident of the United States or partnership or other pass-through entity for U.S. federal income tax purposes). This summary does not discuss non-income taxes, any aspect of the U.S. federal alternative minimum tax or state, local or non-U.S. taxation. This summary is based on current provisions of the Internal Revenue Code of 1986, as amended (“Code”), Treasury regulations, judicial opinions, published positions of the Internal Revenue Service (“IRS”) and all other applicable authorities (all such sources of law, “Tax Authorities”). The Tax Authorities are subject to change, possibly with retroactive effect.

If a partnership (or an entity or arrangement classified as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our common stock, you should consult your tax advisor.

WE URGE PROSPECTIVE NON-U.S. HOLDERS TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSIDERATIONS OF ACQUIRING, HOLDING AND DISPOSING OF SHARES OF COMMON STOCK.

Dividends

In general, any distributions we make to you with respect to your shares of common stock that constitute dividends for U.S. federal income tax purposes will be subject to U.S. withholding tax at a rate of 30% of the gross amount, unless you are eligible for a reduced rate of withholding tax under an applicable income tax treaty and you properly file with the payor an IRS Form W-8BEN, IRS Form W-8BEN-E, or successor form, claiming an exemption from or reduction in withholding under the applicable income tax treaty (special certification and other requirements may apply if our common stock is held through certain foreign intermediaries). A distribution will constitute a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits as determined under the Tax Authorities. Any distribution not constituting a dividend will be treated first as reducing your basis in your shares of common stock and, to the extent it exceeds your basis, as capital gain.

S-15

Dividends we pay to you that are effectively connected with your conduct of a trade or business within the United States (and, if certain income tax treaties apply, are attributable to a U.S. permanent establishment maintained by you) generally will not be subject to U.S. withholding tax if you provide an IRS Form W-8ECI, or successor form, to the payor. Instead, such dividends generally will be subject to U.S. federal income tax, net of certain deductions, at the same graduated individual or corporate rates applicable to U.S. persons. If you are a corporation, effectively connected income may also be subject to a “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty). Dividends that are effectively connected with your conduct of a trade or business within the United States but that, under an applicable income tax treaty, are not attributable to a U.S. permanent establishment maintained by you may be eligible for a reduced rate of U.S. tax under such treaty, provided you comply with certification and disclosure requirements necessary to obtain treaty benefits.

Sale or Other Disposition of Our Common Stock

You generally will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of your shares of our common stock unless:

·    the gain is effectively connected with your conduct of a trade or business within the United States (and, under certain income tax treaties, is attributable to a U.S. permanent establishment you maintain);

·    you are an individual, you are present in the United States for 183 days or more in the taxable year of disposition and you meet other conditions, and you are not eligible for relief under an applicable income tax treaty; or

·    we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes and you hold or have held, directly or indirectly, at any time during the shorter of the five-year period ending on the date of disposition of our common stock and your holding period for our common stock, more than 5% of our common stock. A United States real property holding corporation is any corporation if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market values of its U.S. real property interests, its interests in real property located outside the United States, and any other of its assets which are used or held for use in a trade or business. For purposes of identifying a U.S. real property interest, real property includes personal property associated with the use of the real property. Personal property will be associated with the use of the real property only where both the personal property and the U.S. real property interest with which it is associated are held by the same person or by “related persons.” Personal property associated with the use of real property includes personal property that is predominantly used to exploit unsevered natural products in or upon the land (including mining equipment used to extract ores, minerals, and other natural deposits from the ground). It is unclear whether we are, have at any time within the last five years been, or will be a United States real property holding corporation. If we are or were a United States real property holding corporation within the applicable period, then any gain recognized by non-U.S. Holders on the disposition of our common stock may be subject to Tax, including any applicable withholding tax.

Gain that is effectively connected with your conduct of a trade or business within the United States generally will be subject to U.S. federal income tax, net of certain deductions, at the same rates applicable to U.S. persons. If you are a corporation, the branch profits tax also may apply to such effectively connected gain. If the gain from the sale or disposition of your shares is effectively connected with your conduct of a trade or business in the United States but, under an applicable income tax treaty, is not attributable to a permanent establishment you maintain in the United States, your gain may be exempt from U.S. federal income tax under the income tax treaty. If you are described in the second bullet point above, you generally will be subject to U.S. federal income tax at a rate of 30% on the gain realized, although the gain may be offset by certain U.S. source capital losses realized during the same taxable year.

S-16

Information Reporting and Backup Withholding Requirements

We must report annually to the IRS and to each non-U.S. holder the amount of any dividends or other distributions we pay to you and the amount of tax we withhold on these distributions regardless of whether withholding is required. The IRS may make available copies of the information returns reporting those distributions and amounts withheld to the tax authorities in the country in which you reside pursuant to the provisions of an applicable income tax treaty or exchange of information treaty.

The United States imposes a backup withholding tax on any dividends and certain other types of payments to U.S. persons. You will not be subject to backup withholding tax on dividends you receive on your shares of our common stock if you provide proper certification of your status as a Non-U.S. Holder or you are one of several types of entities and organizations that qualify for an exemption (an “exempt recipient”).

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale of your shares of our common stock outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. If you sell your shares of common stock through a U.S. broker or the U.S. office of a foreign broker, however, the broker will be required to report to the IRS the amount of proceeds paid to you, and also backup withhold on that amount, unless you provide appropriate certification to the broker of your status as a Non-U.S. Holder or you are an exempt recipient. Information reporting will also apply if you sell your shares of our common stock through a foreign broker deriving more than a specified percentage of its income from U.S.-related activities or having certain other connections to the United States, unless such broker has documentary evidence in its records that you are a Non-U.S. Holder and certain other conditions are met, or you are an exempt recipient. Any amounts withheld with respect to your shares of our common stock under the backup withholding rules will be refunded to you or credited against your U.S. federal income tax liability, if any, by the IRS if the required information is furnished in a timely manner.

Foreign Account Tax Compliance Act

Recently enacted legislation will generally impose a withholding tax of 30% on dividends and the gross proceeds of a disposition of our shares paid to a foreign financial institution unless such institution enters into an agreement with the U.S. government to withhold on certain payments and collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which would include certain account holders that are foreign entities with U.S. owners). This legislation will also generally impose a withholding tax of 30% on dividends and the gross proceeds of a disposition of our shares paid to a non-financial foreign entity unless such entity provides the withholding agent with a certification identifying the direct and indirect U.S. owners of the entity. These withholding taxes could potentially be imposed on dividends paid on our common stock after June 30, 2013, and on gross proceeds from sales or other dispositions of our common stock after December 31, 2016. Under certain circumstances, a holder of common stock may be eligible for a refund or credit of such taxes. You should consult your own tax advisor as to the possible implications of this legislation on your investment in shares of our common stock.

S-17

The underwriters are obligated to take and pay for all of the shares of common stock if any of such shares are taken. However, the underwriters are not required to take or pay for the shares of common stock covered by the underwriters’ over-allotment option described below.

Over-Allotment Option

We have granted the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to an aggregate of additional shares of common stock to cover over-allotments, if any, at the public offering price set forth on the cover page of this prospectus supplement, less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the shares of common stock offered by this prospectus.

Commission and Expenses

The underwriters have advised us that they propose to offer the shares of common stock to the public at the initial public offering prices set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $ per share of common stock. After this offering, the public offering price and concession to dealers may be changed by the underwriters. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement. The common stock are offered by the underwriters as stated herein, subject to receipt and acceptance by them and subject to their right to reject any order in whole or in part. The underwriters have informed us that they do not intend to confirm sales to any accounts over which they exercise discretionary authority.

Electronic Distribution

This prospectus supplement and the accompanying prospectus in electronic format may be made available on websites or through other online services maintained by the underwriter, or by its affiliates. Other than this prospectus supplement and the accompanying prospectus in electronic format, the information on any underwriter’s website and any information contained in any other website maintained by any underwriter is not part of this prospectus supplement, the accompanying prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter in its capacity as underwriter, and should not be relied upon by investors.

Determination of Offering Price

The public offering price of the shares we are offering and other terms of the shares were negotiated between us and the underwriter, based on the trading of our common stock prior to the offering, among other things. Other factors considered in determining the public offering price of the shares we are offering and other terms of the shares include the history and prospects of the Company, the stage of development of our business, our business plans for the future and the extent to which they have been implemented, an assessment of our management, general conditions of the securities markets at the time of the offering and such other factors as were deemed relevant.

Lock-up Agreements

Our officers and directors have agreed with the underwriter to be subject to a lock-up period of 90 days following the date of this prospectus. This means that, during the applicable lockup period, such persons may not to offer for sale, contract to sell, sell, distribute, grant any option, right to warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any shares of our common stock or any securities convertible into, or exercisable or exchangeable for, shares of our common stock. Certain limited transfers are permitted during the lock-up period if the transferee agrees to these lock-up restrictions.

We have also agreed, in the underwriting agreement, to similar lock-up restrictions on the issuance and sale of our securities for 90 days following the date of this prospectus, although we will be permitted to issue stock options to directors, officers or employees under our existing plans. The 90-day lock-up period is subject to an additional extension to accommodate our reports of financial results or material news releases. H.C. Wainwright may, in its sole discretion and without notice, waive the terms of any of these lock-up agreements.

Price Stabilization, Short Positions and Penalty Bids

In connection with the offering the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act:

• Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

• Over-allotment involves sales by an underwriter of shares in excess of the number of shares such underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by an underwriter is not greater than the number of shares that it may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. The underwriters may close out any covered short position by either exercising their over-allotment option and/or purchasing shares in the open market.

S-19

• Syndicate covering transactions involve purchases of shares of the common stock in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of shares to close out the short position, an underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase shares through the over-allotment option. If an underwriter sells more shares than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if an underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

• Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the common stock. In addition, neither we nor the underwriters make any representations that the underwriters will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

SUMMARY

This summary highlights information contained elsewhere or incorporated by reference in this prospectus and does not contain all of the information you should consider in making your investment decision. You should read this summary together with the more detailed information included elsewhere or incorporated by reference in this prospectus, including financial statements and the related notes. You should carefully consider, among other things, the matters discussed under “Risks Factors” in the 2011 Form 10-K, the First Quarter Form 10-Q, the Second Quarter 10-Q, the Third Quarter 10-Q and in other documents that we subsequently file with the Commission that are incorporated by reference herein.

The Company

The Company is a Nevada-based, gold and silver mining company with extensive, contiguous property in the historic Comstock and Silver City mining districts (collectively, the “Comstock District”). The Comstock District is located within the western portion of the Basin and Range Province of Nevada, between Reno and Carson City. The Company began acquiring properties and developing projects in the Comstock District in 2003. Since then, the Company has consolidated a substantial portion of the Comstock District, secured permits, built an infrastructure and brought exploration projects into production.

The goal of our strategic plan is to deliver stockholder value by validating qualified resources (measured and indicated) and reserves (probable and proven) of at least 3,250,000 gold equivalent ounces in 2013, and commence commercial mining and processing operations with annual production rates of approximately 20,000 gold equivalent ounces.

Because of the Comstock District’s historical significance, the geology is well known and has been extensively studied by the Company, our advisors and many independent researchers. We have amassed a large library of historical and current data and detailed surface mapping of Comstock District properties. We use such data in conjunction with our drilling programs to expand our understanding of the Comstock District’s structural geology as well as its broader geological footprint.

The Company has 1,357 reverse circulation drilling (“RC”) and core holes, representing over 410,500 feet of drill data in the Lucerne Resource Area. This data has furthered our knowledge of the Lucerne’s mineralization and provided the information used to develop the mine plan for commencing production on the west side of the Lucerne. We also have 323 RC and core holes, representing over 59,000 feet of drill data in our Dayton Resource Area. In our exploration and development campaigns, all drilling, surface and down-hole surveying, hole abandonment, geologic logging, sampling, and assays were performed to industry-recognized standards.

Our Lucerne Resource Area is located in Storey County, Nevada, approximately three miles south of Virginia City and 30 miles southeast of Reno. Our Dayton Resource Area, the proposed site for our second commercial mining activities, is located in Lyon County, Nevada, approximately six miles south of Virginia City. Access to the properties is by State Route 342, a paved highway.

We continue acquiring additional properties in the Comstock District, expanding our footprint and creating opportunities for exploration and mining. The Company now owns or controls approximately 5,869 acres of mining claims in the Comstock District. The acreage is comprised of 1,336 acres of patented claims (private lands) and surface parcels (private lands) and 4,533 acres of unpatented mining claims, which the Bureau of Land Management (“BLM”) administers.

Strategic Plan

In April 2010, the Board approved a strategic plan designed to restructure and recapitalize the Company, accelerate mine development and production and continue exploration. Since then, we have accomplished all of the key milestones contemplated by the strategic plan within the time frame contemplated to date, including:

• operational and management restructuring, including the appointment of a new chief executive officer, chief accounting officer, controller, vice president of strategic resource planning, vice president of operations, metallurgical process manager, senior mine planner and director of environmental and regulatory management;

• the 200:1 reverse stock split of all common shares outstanding;

• the acquisition of ownership or control of more than 1,800 acres, leading to substantial increases in the Company’s measured, indicated and inferred resources;

• balance sheet restructuring, including the exchange of approximately $29.4 million of secured convertible indebtedness for convertible preferred equity;

• an equity capital raise of approximately $35.75 million through the issuance of convertible preferred equity;

• listing of the Company’s Common Stock on the NYSE MKT; and

• obtaining key required permits for exploration drilling and production purposes.

As part of the strategic plan, the Company has scheduled the exploration and development drilling intended to validate mine design and identify qualified resources and reserves with three intermediate objectives of validating measured and indicated resources containing 1,000,000 gold equivalent ounces, 1,500,000 gold equivalent ounces, and 2,000,000 gold equivalent ounces, respectively, and the long term planned objective of 3,250,000 gold equivalent ounces to be achieved in 2013, with an annual run rate of at least 20,000 gold equivalent ounces with respect to the Company’s existing exploration targets. The Company has already met the first two intermediate exploration objectives. The Company commenced the start of production operations in September 2012. See “Recent Developments — Production” below.

Related Party Transactions

Northern Comstock LLC

On October 20, 2010, the Company entered into an operating agreement to form Northern Comstock LLC (“Northern Comstock”) with Mr. Winfield, a shareholder of the Company, and an entity controlled by Mr. Winfield, DWC Resources, Inc. (“DWC”). As part of the operating agreement, the Company obtained the exclusive rights of production and exploration on certain property formerly owned by DWC in Storey County, Nevada and two parcels leased by Mr. John Winfield in Storey County, Nevada from the Sutro Tunnel Company and Virginia City Ventures.

5

As part of the operating agreement, the Company obtained the exclusive rights of production and exploration on certain parcels in Storey County, Nevada. The terms of the operating agreement provide that on each anniversary of the operating agreement, up to and including the thirty-ninth (39th) anniversary, the Company will make contributions in the amount of $862,500, in the form of Series A-1 Convertible Preferred Stock or cash upon request of Northern Comstock. If an event of default occurs under the operating agreement, the additional capital contributions could be accelerated and the entire unpaid amount of the Company’s capital contribution, up to the aggregate 34,500 shares of Series A-1 Convertible Preferred Stock (approximately 53 million shares of Common Stock as converted), could become issuable immediately. The Company has made the first three capital contributions and therefore there are capital contributions of 31,912.5 shares of Series A-1 Convertible Preferred Stock (approximately 49.0 million shares of Common Stock as converted) remaining as of October 31, 2012. The operating agreement further requires the Company to make certain capital expenditures of not less than $750,000 over five years with respect to each parcel.

Mineral production from the DWC-contributed property is subject to a royalty on a sliding scale to DWC. At gold prices over $750 per ounce, production of the first 500,000 ounces is subject to a 3% net smelter royalty. Production over 500,000 ounces is subject to a 6% net smelter royalty.

Mineral production on the Sutro property is subject to a royalty on a sliding scale to John Winfield. At gold prices over $250 per ounce, production of the first 500,000 ounces is subject to a 1% net smelter royalty. Production over 500,000 ounces is subject to a 2% net smelter royalty.

Under the terms of the operating agreement, all operating activities from the minerals or finished products produced from the parcel are conducted by the Company and recognized in the Company’s consolidated financial statements. The Company has no right to receive periodic or liquidating distributions related to any amounts contributed to Northern Comstock. The payments to Northern Comstock do not result in the acquisition of any equity interest in Northern Comstock as there is no entitlement to receive future distributions or changes in the fair value of the net assets of Northern Comstock.

Tax Indemnification

On October 20, 2010, the Company exchanged senior secured convertible and senior indebtedness owed to Mr. Winfield and certain entities affiliated with Mr. Winfield (the “Winfield Group”) for shares of Series A-1 Convertible Preferred Stock. As part of the exchange, the Company agreed to indemnify the Winfield Group for any amounts as part of the exchange that are determined to be taxable as ordinary income to each member of the Winfield Group. Such indemnified amounts would include (i) any federal, state and local income tax, penalties and interest such member is actually obligated to pay out-of-pocket as a result of such determination, after taking into account (a) all increases in federal, state and local income taxes actually payable as a result of the receipt of any such indemnity payment and (b) the deduction to which such member would be entitled for federal income tax purposes for state and local income taxes paid. The Company may at its option, pay the indemnity amount either in cash or in a number of common shares equal to the indemnity amount divided by the average of the volume weighted average closing prices of common shares for the five consecutive trading days ending on the trading day that is immediately prior to the date of such payment. As of September 30, 2012, the Company has recorded a liability of $3,985,664 for this tax indemnification at the amount that is probable of being indemnified by the Company.

Recent Developments

Production

Our strategic plan called for a return to mine production during the third quarter of 2012. During the second quarter of 2012, we completed the expansion of the heap leach pad from its three existing cells to five cells. We also received and installed the new Merrill Crowe facility. We installed the crushing facility, including the jaw and cone crusher, the super stacker, conveyors and related components on site.

We have hired essentially all of our planned mine and processing staff. This includes the mining operations, crushing plant, Merrill Crowe facility, laboratory, and metallurgical process staff. With the additions of these staff, we are able to run our full mining operations.

In the third quarter of 2012, we commissioned the crushing and Merrill Crowe facilities, including successful calibration and testing of the facility’s equipment. We commenced the haulage of mineralized material from the mine to the crushing facility, and crushing and stacking material. Once material was stacked, we commenced processing and poured doré beginning in late September 2012.

Through October 31, 2012, the Company shipped 1,258 ounces of gold and 14,802 ounces of silver. In addition, the Company delivered 28 ounces of gold and 292 ounces of silver to the Northwest Territorial Mint, In Dayton, Nevada, to facilitate the minting of the commemorative bar celebrating the first pour. The combined sale of metal (received payments and payments due on gold and silver sold) was in excess of $2.5 million.

Through October 31, 2012, the Company has crushed over 175,000 dry tons of mineralized material. Material placed on the heap leach pad after crushing remains under solution for as long as the pad is utilized. Throughout this period, the recovery of gold and silver continues, but the most effective economic recovery of gold and silver takes between 45 to 60 days to complete. The recovery of gold and silver from the first month represents only a portion of the expected recovery. Once initiated, the Merrill-Crowe process is continuous. Likewise, the heap is continuously expanded as new material is brought from the mine and sent through the crusher. As a result, the amount of gold and silver recovered and shipped for payment always represents only a fraction of the ultimately recovered amount of gold and silver potential in the amount actually on the heap.

The Company has completed a financial analysis for the Lucerne mine and anticipates annual operating expenses, including mining, processing, royalties and mine administration costs of approximately $13.3 million per annum, with a production schedule that commences processing at a rate of one million tons per annum. The Company anticipates temporary, higher haulage costs of $2.25 million for the first nine months of operations in 2013, associated with hauling on an alternative route until a new Right of Way permit is issued to us by the BLM. These mining, processing and related costs do not include corporate administration or other general and administrative costs, nor do they include exploration and mine development costs.

Surety Bond

In July 2012, the Company placed a $4.67 million reclamation surety bond, through the Lexon Surety Group with the State of Nevada’s Bureau of Mining Regulation Reclamation. The bond insures for the estimated costs required to safely reclaim the natural environment to the regulatory standards established by the State of Nevada’s Division of Environmental Protection with the purposes of ensuring public safety, protecting the waters of the state, and providing for post mining land use.

7

Working Capital and Equipment Financings

In July 2012, the Company entered into a Master Loan and Security Agreement and other arrangements with Caterpillar Financial Services Corporation (the “Cat Equipment Facility”) pursuant to which the Company may borrow up to $5 million secured by certain equipment of the Company. On July 30, 2012, the Company borrowed $2 million under the Cat Equipment Facility. The Cat Equipment Facility will bear interest at a rate of 5.85% with a term of 30 months except in the event of a default, including the occurrence of certain liquidity events, the principal balance will bear interest at a rate of the lesser of 18% per annum or the highest applicable rate allowed by law.

In July 2012, the Company also entered into an agreement with Resource Income Fund (“RIF”), with Auramet Trading, LLC (“Auramet”) acting as gold agent, pursuant to which the Company may borrow up to $5 million outstanding at any one time. The Company’s obligations under the agreement are secured by a security interest in all personal property of the Company and its wholly-owned subsidiary Comstock Mining LLC (the “Subsidiary”), and certain real estate owned by the Company within the Company’s starter mine (the “Starter Mine Patents”). The proceeds will be used for working capital and capital expenditures associated with the commencement of production. The proceeds will be repaid through the delivery of 3,720 ounces of gold payable in 12 semi-monthly deliveries of 310 ounces each beginning February 2013 and ending July 2013, or December 2013, if any amounts are redrawn under the agreement. The agreement is non-interest bearing except in the event of a default, in which case the balance would then bear interest at the lesser rate of 15% per annum or the highest applicable rate allowed by law.

The Company also granted to RIF a call option to purchase 5,950 ounces of gold at a strike price of $2,000 per ounce, exercisable on, and expiring on, July 24, 2013. In connection with entry into the agreement, the Company and the Subsidiary have also entered into a purchase and sale agreement with Auramet, and the Company entered into a trading agreement the terms of which will govern all transactions of metals between Auramet and the Company. The Company drew down $5 million under the agreement in July 2012.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. Pursuant to the terms of our Series A-1 Convertible Preferred Stock, Series A-2 Convertible Preferred Stock and Series B Convertible Preferred Stock, we are prohibited from issuing debt without the prior written consent of the preferred stockholders. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indentures, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the senior debt securities under the senior indenture that we will enter into with the trustee named in the senior indenture. We will issue the subordinated debt securities under the subordinated indenture that we will enter into with the trustee named in the subordinated indenture. The indentures will be qualified under the Trust Indenture Act of 1939. We use the term “debenture trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable. We have filed forms of indentures to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the Commission.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indentures that contains the terms of the debt securities. Except as we may otherwise indicate, the terms of the senior indenture and the subordinated indenture are identical.

• any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities, including any additional events of default or covenants provided with respect to the debt securities, and any terms that may be required by us or advisable under applicable laws or regulations.

We will set forth in the prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our Common Stock or our other securities. We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our Common Stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indentures will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate. If the debt securities are convertible into or exchangeable for our other securities or securities of other entities, the person with whom we consolidate or merge or to whom we sell all of our property must make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

Events of Default Under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

14

• if we fail to pay interest when due and payable and our failure continues for 90 days and the time for payment has not been extended or deferred;

• if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable and the time for payment has not been extended or delayed;

• if we fail to observe or perform any other covenant contained in the debt securities or the indentures, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive notice from the debenture trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

• if specified events of bankruptcy, insolvency or reorganization occur.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the debenture trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the debenture trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the debenture trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the debenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the debenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the debenture trustee, or exercising any trust or power conferred on the debenture trustee, with respect to the debt securities of that series, provided that:

• the direction so given by the holder is not in conflict with any law or the applicable indenture; and

• subject to its duties under the Trust Indenture Act of 1939, the debenture trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

A holder of the debt securities of any series will have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies only if:

15

• the holder has given written notice to the debenture trustee of a continuing event of default with respect to that series;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the debenture trustee to institute the proceeding as trustee; and

• the debenture trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the debenture trustee regarding our compliance with specified covenants in the indentures.

Modification of Indenture; Waiver

We and the debenture trustee may change an indenture without the consent of any holders with respect to specific matters:

• to fix any ambiguity, defect or inconsistency in the indenture;

• to comply with the provisions described above under “Description of Debt Securities — Consolidation, Merger or Sale;”

• to comply with any requirements of the Commission in connection with the qualification of any indenture under the Trust Indenture Act of 1939;

• to add to, delete from or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture;

• to provide for the issuance of and establish the form and terms and conditions of the debt securities of any series as provided under “Description of Debt Securities — General” to establish the form of any certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities;

• to evidence and provide for the acceptance of appointment hereunder by a successor trustee;

• to provide for uncertificated debt securities in addition to or in place of certificated debt securities and to make all appropriate changes for such purpose;

• to add to our covenants such new covenants, restrictions, conditions or provisions for the protection of the holders, and to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default; or

• to change anything that does not materially adversely affect the interests of any holder of debt securities of any series.

16

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the debenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the debenture trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

• extending the fixed maturity of the series of debt securities;

• reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption of any debt securities; or

• reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver.

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

• register the transfer or exchange of debt securities of the series;

• replace stolen, lost or mutilated debt securities of the series;

• maintain paying agencies;

• hold monies for payment in trust;

• recover excess money held by the debenture trustee;

• compensate and indemnify the debenture trustee; and

• appoint any successor trustee.

In order to exercise our rights to be discharged, we must deposit with the debenture trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depositary named by us and identified in a prospectus supplement with respect to that series. See “Legal Ownership of Securities” for a further description of the terms relating to any book-entry securities.

At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

17

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

• issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

• register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Debenture Trustee

The debenture trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the debenture trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the debenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the debenture trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

18

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

Subordination of Subordinated Debt Securities

The subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of subordinated debt securities that we may issue, nor does it limit us from issuing any other secured or unsecured debt.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of Common Stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with Common Stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the Commission, the form of warrant agreement, including a form of warrant certificate, that describes the terms of the particular series of warrants we are offering before the issuance of the related series of warrants. The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to the particular series of warrants that we may offer under this prospectus. We urge you to read the applicable prospectus supplements related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectuses, and the complete warrant agreements and warrant certificates that contain the terms of the warrants.

19

General

We will describe in the applicable prospectus supplement the terms of the series of warrants being offered, including:

• the offering price and aggregate number of warrants offered;

• the currency for which the warrants may be purchased;

• if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

• if applicable, the date on and after which the warrants and the related securities will be separately transferable;

• in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise;

• in the case of warrants to purchase Common Stock or preferred stock, the number of shares of Common Stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;

• the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreements and the warrants;

• the terms of any rights to redeem or call the warrants;

• any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;

• the dates on which the right to exercise the warrants will commence and expire;

• the manner in which the warrant agreements and warrants may be modified;

• a discussion of any material or special United States federal income tax consequences of holding or exercising the warrants;

• the terms of the securities issuable upon exercise of the warrants; and

• any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

20

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

• in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or

• in the case of warrants to purchase Common Stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent.

Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements will be governed by and construed in accordance with the laws of the State of New York.

Enforceability of Rights by Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

DESCRIPTION OF UNITS

We may issue, in one more series, units consisting of Common Stock, preferred stock, debt securities and/or warrants for the purchase of Common Stock, preferred stock and/or debt securities in any combination. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

21

We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the Commission, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

We will issue each unit so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which we issue a unit may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

• the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

• any provisions of the governing unit agreement that differ from those described below; and

• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those described under “Description of Common Stock,” “Description of Preferred Stock,” “Description of Debt Securities” and “Description of Warrants” will apply to each unit and to any Common stock, preferred stock, debt security or warrant included in each unit, respectively.

Issuance in Series

We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

We, and any unit agent and any of their agents, may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary. See “Legal Ownership of Securities” below.

22

LEGAL OWNERSHIP OF SECURITIES

We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the “holders” of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as “indirect holders” of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

Only the person in whose name a security is registered is recognized as the holder of that security. Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect holders, and not holders, of the securities.

Street Name Holders

We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in their own names or in “street name.” Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

For securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not holders, of those securities.

Legal Holders

Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.

23

For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the holders, and not the indirect holders, of the securities. Whether and how the holders contact the indirect holders is up to the holders.

Special Considerations For Indirect Holders

If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

• how it handles securities payments and notices;

• whether it imposes fees or charges;

• how it would handle a request for the holders’ consent, if ever required;

• whether and how you can instruct it to send you securities registered in your own name so you can be a holder, if that is permitted in the future;

• how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and

• if the securities are in book-entry form, how the depositary’s rules and procedures will affect these matters.

Global Securities

A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.

Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all securities issued in book-entry form.

A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under “Special Situations When a Global Security Will Be Terminated.” As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the security, but only an indirect holder of a beneficial interest in the global security.

If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations For Global Securities

The rights of an indirect holder relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.

If securities are issued only in the form of a global security, an investor should be aware of the following:

• an investor cannot cause the securities to be registered in his or her name, and cannot obtain non-global certificates for his or her interest in the securities, except in the special situations we describe below;

• an investor will be an indirect holder and must look to his or her own bank or broker for payments on the securities and protection of his or her legal rights relating to the securities, as we describe above;

• an investor may not be able to sell interests in the securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form;

• an investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;

• the depositary’s policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor’s interest in a global security;

• we and any applicable trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership interests in a global security, nor do we or any applicable trustee supervise the depositary in any way;

• the depositary may, and we understand that DTC will, require that those who purchase and sell interests in a global security within its book-entry system use immediately available funds, and your broker or bank may require you to do so as well; and

• financial institutions that participate in the depositary’s book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the securities.

There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations When a Global Security Will Be Terminated

In a few special situations described below, the global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in securities transferred to their own name, so that they will be direct holders. We have described the rights of holders and street name investors above.

25

Unless we provide otherwise in the applicable prospectus supplement, the global security will terminate when the following special situations occur:

• if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary within 90 days;

• if we notify any applicable trustee that we wish to terminate that global security; or

• if an event of default has occurred with regard to securities represented by that global security and has not been cured or waived.

The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the applicable prospectus supplement. When a global security terminates, the depositary, and not we or any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus from time to time. Registration of the securities covered by this prospectus does not mean, however, that those securities will necessarily be offered or sold. We may sell the securities separately or together: through one or more underwriters in a public offering and sale by them; directly to investors (in those jurisdictions where we are authorized to do so); through agents; or through a combination of any of these methods of sale. We may sell the securities from time to time: in one or more transactions at a fixed price or prices, that may be changed from time to time; at market prices prevailing at the time of sale; at prices related to prevailing market prices; or at negotiated prices. We will describe the method of distribution of the securities and the terms of the offering in the applicable prospectus supplement.

If underwriters are used for the sale of any securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the securities if they purchase any of the securities. We may grant underwriters who participate in the distribution of securities an option to purchase additional securities in connection with the distribution. Any underwriter or agent involved in the offer and sale of the securities will be named in the related prospectus supplement.

Underwriters may offer and sell the securities at a fixed price or prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices, or at negotiated prices. We also may, from time to time, authorize dealers, acting as our agents, to offer and sell the securities upon the terms and conditions described in the related prospectus supplement. Underwriters may receive compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agent. Underwriters may sell the securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions, which may be changed from time to time, from the purchasers for whom they may act as agents.

Any underwriting compensation paid by us to underwriters or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be stated in the related prospectus supplement. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the applicable securities laws.

Shares of our Common Stock are quoted on the NYSE MKT. In connection with any offering of securities, the underwriters may purchase and sell securities in the open market and engage in over-allotment transactions, short-covering transactions, penalty bids and stabilizing transactions in accordance with Regulation M under the Exchange Act. Over-allotment involves sales of securities in excess of the offering size of securities to be purchased by the underwriters in an offering, which creates a short position for the underwriters. Short-covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Stabilizing transactions consist of certain bids or purchases of securities made for the purpose of preventing or retarding a decline in the market price of the securities while the offering is in progress. Any of these activities may have the effect of preventing or retarding a decline in the market price of the securities being offered. They may also cause the price of the securities being offered to be higher than the price that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time. We make no representation as to the direction or magnitude of any affect that such transactions may have on the price of the securities.

Underwriters, dealers and agents may be entitled, under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments made by such underwriters, dealers or agents related to such civil liabilities.

Certain of the underwriters, dealers or agents and their associates may engage in transactions with, and perform other services for us in the ordinary course of business for which they may receive compensation.
