SOLITARIO ZINC CORP.
 
Shares of Common Stock
 
We have entered into an At The Market Offering Agreement, or the Offering Agreement, with H.C. Wainwright & Co., LLC, or Wainwright, as agent. In accordance with the terms of the Offering Agreement, this prospectus supplement, and the accompanying prospectus, we may from time to time offer and sell shares of our common stock having an aggregate offering price of up to $9,000,000 through the agent.
 
Our shares of common stock trade on the NYSE American under the symbol “XPL.” On January 28, 2021, the last sale price of the shares as reported on the NYSE American was $0.73 per share. We have applied to the NYSE American for the listing of the shares of our common stock being offered by this prospectus supplement and the accompanying prospectus. Listing will be subject to us fulfilling all the listing requirements of the NYSE American and is a condition of sales under the Offering Agreement.
 
Sales of common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in transactions that are deemed to be “at-the-market” offerings as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended, or the Securities Act. Wainwright will make all sales using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between Wainwright and us. Sales of the shares of our common stock, if any, through Wainwright or directly to Wainwright acting as principal will be made by means of ordinary brokers’ transactions on the NYSE American, the existing United States trading market for our common stock, or any other existing trading market in the United States for our common stock, sales made to or through a market maker other than on an exchange or otherwise, directly to the sales agent as principal, in negotiated transactions with our prior approval at market prices prevailing at the time of sale or at prices related to prevailing market prices, or any other method permitted by law. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock into the NYSE American or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.
 
Wainwright will receive from us a commission of 3% of the gross sales price of all shares sold through it under the Offering Agreement. In connection with the sale of the common stock on our behalf, Wainwright may be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Wainwright may be deemed to be underwriting commissions or discounts.
 
As January 28, 2021 the aggregate market value of our outstanding voting and non-voting common equity held by non-affiliates was $38,349,000 based on 58,108,366 shares of outstanding our common stock outstanding, of which 52,533,278 shares were held by non-affiliates, and the last reported sale price of our Common Stock of $0.73 per share on January 28, 2021. Pursuant to General Instruction I.B.6 of Form S-3, in no event will we sell securities in a public primary offering with a value exceeding more than one-third of our public float in any 12-month period so long as our public float remains below $75,000,000. During the previous 12 calendar months prior to and including the date of this prospectus supplement, we have offered $0 of our securities pursuant to General Instruction I.B.6 of Form S-3.
 
Investing in our common stock involves risks including those described in the “Risk Factors” section beginning on page S-4 of this prospectus supplement and page 2 of the accompanying prospectus.
 
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement and the accompanying prospectus to which it relates are truthful or complete. Any representation to the contrary is a criminal offense.
 
H.C. Wainwright & Co.
 
The date of this prospectus supplement is February 2, 2021.

PROSPECTUS SUPPLEMENT SUMMARY
 
This summary highlights information incorporated by reference into or contained elsewhere in this prospectus supplement and the accompanying prospectus. This summary may not contain all of the information that may be important to you. You should read carefully all of the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, including the information set forth under the caption “Risk Factors” beginning on page S-4 of this prospectus supplement and in our 2019 Form 10-K, subsequently filed Quarterly Reports on Form 10-Q, and our consolidated financial statements and the related notes thereto incorporated by reference herein before making a decision to purchase our shares.
 
Overview of Our Business
 
We are an exploration stage company under Industry Guide 7, as issued by the SEC, with a focus on the acquisition of precious and base metal properties with exploration potential and the development or purchase of royalty interests. Currently our primary focus is the acquisition and exploration of zinc-related exploration mineral properties. However, we continue to evaluate other mineral properties for acquisition. We acquire and hold a portfolio of exploration properties for future sale, joint venture, or to create a royalty prior to the establishment of proven and probable reserves. Although our mineral properties may be developed in the future by us, through a joint venture or by a third party, we have never developed a mineral property.
 
Our current geographic focus for the evaluation of potential mineral property assets is in North and South America; however, we have conducted property evaluations for potential acquisition in other parts of the world. We currently consider our carried interest in the Florida Canyon project in Peru and our interest in the Lik project in Alaska to be our core mineral property assets. In addition, we have one other exploration property in Peru. We are conducting independent exploration activities on our own and through joint ventures operated by our partners in Peru and the United States.
 
In 2017 we acquired a 50% operating interest in the Lik zinc-lead-silver property in Northwest Alaska, which is estimated to contain a large tonnage, high-grade deposit potentially mineable by open-pit methods. Teck American Inc., a wholly owned subsidiary of Tech Resources Limited is a 50% partner in the Lik project, and they act as the project manager. A Preliminary Economic Assessment (“PEA”) was completed on the Lik deposit in 2014.
 
We hold a 39% interest in the advanced, high-grade, Florida Canyon zinc project located in northern Peru. The project has a significant mineral resource and we are fully carried to production by our joint venture partner Nexa Resources, Ltd. (“Nexa”). Solitario and Nexa completed a PEA on the Florida Canyon deposit in August 2017. Except for the 2018-2019 drilling program, Nexa has funded 100% of project expenditures since the inception of the Florida Canyon joint venture in 2006. The Florida Canyon project consists of 16 concessions comprising 12,600 hectares of mineral rights originally granted to Minera Bongará S.A., our subsidiary incorporated in Peru. The property is located in the Department of Amazonas, northern Peru. Solitario's and Nexa’s property interests are held through the ownership of shares in Minera Bongará S.A., a joint operating company that holds a 100% interest in the mineral rights and other project assets.
 
 We are exploring other mineral properties that may be developed in the future by us or through a joint venture. We also from time to time evaluate mineral assets and projects for acquisition and additional properties on which to potentially buy a royalty.
 
We have been actively involved in mineral exploration projects since 1993. We have recorded revenue in the past from the sale of mineral properties, including from a royalty in January 2019 and the sale in June 2018 of our interest in the royalty on the Yanacocha property. Future revenues from the sale of properties or royalty interests, if any, will likely occur on an infrequent basis (if at all). Historically we have reduced our exposure to the costs of our exploration activities through the use of joint ventures. We anticipate that the use of joint venture funding for some of our exploration activities will continue for the foreseeable future.

Corporate Information

RISK FACTORS
 
An investment in our common stock offered by this prospectus supplement and the accompanying prospectus involves a high degree of risk. You should carefully consider the following risk factors in addition to the remainder of this prospectus supplement and the accompanying prospectus, including the information incorporated by reference, including under the heading “RISK FACTORS” in the accompanying prospectus, in our 2019 Form 10-K and any reports subsequently filed by us with the SEC before making an investment decision. The risks and uncertainties described in these incorporated documents and described below are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or which we currently consider to be immaterial may also impair our business operations. If any of these risks actually occurs, our business, financial condition and results of operations would suffer. In that event, the trading price of our shares could decline, and you may lose all or part of your investment in our shares. The risks discussed below also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements. Please see the section entitled “Cautionary Statement Regarding Forward-Looking Statements” in this prospectus supplement.
 
Additional Risks Relating to the Offering and Our Common Stock
 
Sales of substantial amounts of our common stock or the perception that such sales may occur could cause the market price of our common stock to drop significantly, even if our business is performing well.
 
Future sales of substantial amounts of our common stock, or securities convertible or exchangeable into shares of our common stock, into the public market, including shares of our common stock issuable upon exercise of options and warrants, or perceptions that those sales could occur, could adversely affect the prevailing market price of our common stock and our ability to raise capital in the future. Additionally, the market price of our common stock could decline as a result of sales of shares of our common stock by, or the perceived possibility of sales by, our existing shareholders in the market after this offering. These sales might also make it more difficult for us to sell equity securities at a time and price that we deem appropriate.
 
We may sell additional equity or debt securities in the future to fund our operations, which may result in dilution to our shareholders and impose restrictions on our business.
 
In order to raise additional funds to support our operations, we may sell additional equity or debt securities, which, in the case of equity securities, would result in dilution to all of our shareholders or, in the case of debt securities, impose restrictive covenants that adversely impact our business. The sale of other incurrence of indebtedness would result in increased fixed payment obligations and could also result in restrictive covenants, such as limitations on our ability to incur additional debt and certain operating restrictions that could adversely impact our ability to conduct our business. We have an effective shelf registration statement from which additional shares of common stock and other securities can be offered. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering. If the price per share at which we sell additional shares of our common stock or related securities in future transactions is less than the price per share in this offering, investors who purchase our common stock in this offering will suffer a dilution of their investment. If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected.
 
S-4
 
 
Purchasers in this offering will likely experience immediate and substantial dilution in the book value of their investment.
 
The shares of common stock sold in this offering, if any, will be sold from time to time at various prices. However, the expected offering price per share of common stock may be substantially higher than the net tangible book value per share of common stock. Therefore, if you purchase shares of our common stock in this offering, your interest will be diluted to the extent of the difference between the price per share you pay and the net tangible book value per share of common stock. Assuming that the sale of an aggregate amount of $9,000,000 of shares of our common stock in this offering at an assumed offering price of $0.73 per share, which was the last reported sale price of our common stock on the NYSE American on January 28, 2021, and based on our net tangible book value as of September 30, 2020, if you purchase shares of common stock in this offering you will suffer substantial and immediate dilution of $0.27 per share in the net tangible book value of the share common stock. The future exercise of outstanding options or warrants and other instruments that are convertible or exercisable into common stock, if any, will result in further dilution of your investment. See the section entitled “Dilution” below for a more detailed discussion of the dilution you will incur if you purchase shares of our common stock in this offering.
 
Our management will have broad discretion in the use of the net proceeds from this offering and may allocate the net proceeds from this offering in ways that you and other shareholders may not approve.
 
Our management will have broad discretion in the use of the net proceeds, including for any of the purposes described in the section entitled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. All of the net proceeds will be used at the discretion of management to fund working capital and for general corporate purposes. The failure of our management to use these funds effectively could have a material adverse effect on our business, cause the market price of our common stock to decline and delay the exploration or development at any of our mines or exploration projects. Pending their use, we intend to invest the net proceeds in a variety of capital preservation instruments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities. These investments may not yield a favorable return to our stockholders.
 
The common stock offered hereby will be sold in “at-the-market” offerings, and investors who buy shares at different times will likely pay different prices.
 
Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.
 
The actual number of shares we will issue under the Offering Agreement, at any one time or in total, is uncertain.
 
Subject to certain limitations in the Offering Agreement and compliance with applicable law, we have the discretion to deliver a sales notice to Wainwright at any time throughout the term of the Offering Agreement. The number of shares that are sold by Wainwright after delivering a sales notice will fluctuate based on the market price of our common stock during the sales period and limits we set with Wainwright. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.
 
It is not possible to predict the aggregate proceeds resulting from sales made under the Offering Agreement.
 
Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a placement notice to Wainwright at any time throughout the term of the Offering Agreement. The number of shares that are sold through Wainwright after delivering a placement notice will fluctuate based on a number of factors, including the market price of our common stock during the sales period, any limits we may set with Wainwright in any applicable placement notice and the demand for our common stock. Because the price per share of each share sold pursuant to the Offering Agreement will fluctuate over time, it is not currently possible to predict the aggregate proceeds to be raised in connection with sales under the sales agreement.
 
S-5
 
 
USE OF PROCEEDS
 
We may issue and sell shares of our common stock having aggregate sales proceeds of up to $9,000,000 from time to time. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the Offering Agreement with the agent as a source of financing.
 
We intend to use the net proceeds from this offering for working capital, general corporate purposes, which may include operating expenses, working capital and potential asset or strategic acquisitions.
 
The expected use of the net proceeds from the sale of common stock offered by this prospectus supplement represents our intentions based upon our current plans and business conditions. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors and, as a result, our management will retain broad discretion over the allocation of the net proceeds from this offering. Until we use the net proceeds from this offering for the purposes described above, we may invest them in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.
 
DIVIDEND POLICY
 
We have not paid a dividend in our history and do not anticipate paying a dividend in the foreseeable future. However, at the present time, we are not a party to any agreement that would limit our ability to pay dividends.
 
DILUTION
 
If you purchase any of the shares of common stock offered by this prospectus supplement, you will experience dilution to the extent of the difference between the price per share of common stock you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of September 30, 2020 was approximately $24,008,000, or $0.41 per share of common stock. Net tangible book value per share represents our total tangible assets (which excludes intangible assets such as deferred taxes), less our total liabilities, divided by the aggregate number of shares of our common stock outstanding as of September 30, 2020.
 
After giving effect to the assumed sale of an aggregate of $9,000,000 of shares of common stock in this offering at the assumed public offering price of $0.73 per share (the closing sales of our common stock on the NYSE American on January 28, 2021), and after deducting the commissions and other estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2020 would have been approximately $32,638,000, or $0.46 per share. This amount represents an immediate increase in net tangible book value of $0.05 per share to existing stockholders as a result of this offering and immediate dilution of approximately $0.27 per share to new investors purchasing our common stock in this offering.
 
The following table illustrates this dilution on a per share basis. The as-adjusted information below is illustrative only and will adjust based on the actual price to the public and the actual number of shares sold pursuant to this prospectus supplement. The shares sold in this offering, if any, will be sold from time to time at various prices.
 
Assumed public offering price per share 
 
 
 
 $0.73 
     Net tangible book value per share as of September 30, 2020 (unaudited)….
 $0.41 
    
      Increase in net tangible book value per share attributable to this offering 
 $0.05 
    
As-adjusted net tangible book value per share after this offering 
    
 $0.46 
Dilution per share to new investors participating in this offering 
    
 $0.27 
 
A $0.10 increase in the assumed public offering price of $0.73 per share (the closing sales of our common stock on the NYSE American on January 28, 2021), to $0.83 per share would increase the as-adjusted net tangible book value by $0.06 per share and would increase the dilution to new investors by $0.36 per share, after deducting commissions and offering expenses payable by us in connection with this offering. A $0.10 decrease in the assumed public offering price of $0.73 per share (the closing sales price of our common stock on the NYSE American on January 28, 2021), to $0.63 per share would increase the dilution to new investors by $0.18 per share, after deducting commissions and offering expenses payable by us in connection with this offering.

1,438 additional shares of common stock reserved for future issuance under our omnibus stock and incentive plan as of September 30, 2020.
 
To the extent that outstanding options are exercised, investors purchasing our common stock in this offering will experience further dilution. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.
 
PLAN OF DISTRIBUTION
 
We have entered into an At The Market Offering Agreement with Wainwright, under which we may issue and sell our common stock having an aggregate gross sales price of up to $9,000,000 from time to time through Wainwright acting as agent.  The Offering Agreement provides that sales of our common stock, if any, under this prospectus supplement may be made in sales deemed to be “at-the-market” equity offerings as defined in Rule 415(a)(4) promulgated under the Securities Act. If we and Wainwright agree on any method of distribution other than sales of shares of our common stock into the NYSE American or another existing trading market in the United States at market prices, we will file a further prospectus supplement providing all information about such offering as required by Rule 424(b) under the Securities Act. No sales will be made in Canada or into any trading market in Canada.
 
Wainwright will offer the common stock subject to the terms and conditions of the Offering Agreement on a daily basis or as otherwise agreed upon by us and Wainwright on any day that: (i) is a trading day for the NYSE American; (ii) we have instructed Wainwright to make such sales; and (iii) we have satisfied the conditions under Section 6 of the Offering Agreement. We will designate the maximum amount of common stock to be sold through Wainwright on a daily basis. Subject to the terms and conditions of the Offering Agreement, Wainwright will use its commercially reasonable efforts to sell on our behalf all of the common stock so designated or determined. We or Wainwright may suspend the offering of common stock being made through Wainwright under the Offering Agreement upon proper notice to the other party.
 
We will pay Wainwright commissions, in cash, for its services in acting as agent in the sale of our common stock. Wainwright will be entitled to a placement fee of 3% of the gross sales price of the shares sold. Because there is no minimum offering amount required as a condition of this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse Wainwright for certain specified expenses, including the fees and disbursements of its legal counsel, in an amount not to exceed $50,000, as provided in the Offering Agreement. Additionally, pursuant to the terms of the Offering Agreement, we agreed to reimburse Wainwright for the fees and disbursements of its legal counsel in connection with Wainwright’s ongoing diligence, drafting and other filing requirements arising from the transactions contemplated by the Offering Agreement in an amount not to exceed $2,500 in the aggregate per calendar quarter. We estimate that the total expenses for the offering, excluding compensation and reimbursements payable to Wainwright under the terms of the Offering Agreement, will be approximately $75,000.
 
Settlement for sales of common stock will occur at 10:00 a.m. (New York City time), or at some other time that is agreed upon by us and Wainwright in connection with a particular transaction, on the second trading day following sale of the shares, in return for payment of the net proceeds to us. Sales of our common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Wainwright may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.
 
S-7
 
 
Wainwright has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell on our behalf all of the common stock requested to be sold by us, subject to the conditions set forth in the Offering Agreement. In connection with the sale of the common stock on our behalf, Wainwright may be deemed to be an “underwriter” within the meaning of the Securities Act and the compensation of Wainwright may be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Wainwright against certain civil liabilities, including liabilities under the Securities Act.
 
The offering of our common stock pursuant to the Offering Agreement will terminate upon the earlier of (i) the issuance and sale of all of the common stock subject to the Offering Agreement, and (ii) the termination of the Offering Agreement as permitted therein. We may terminate the Offering Agreement at any time upon ten business days’ prior notice.
 
Wainwright and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees, although we have no current agreements to do so. To the extent required by Regulation M, Wainwright will not engage in any market making activities involving our common stock while the offering is ongoing under this prospectus supplement.
 
We have applied to list the shares of common stock sold in this offering on the NYSE American, and approval for such listing is a condition for sales under the Offering Agreement.
 
This prospectus in electronic format may be made available on a website maintained by Wainwright and Wainwright may distribute this prospectus electronically.

ABOUT THIS PROSPECTUS
 
This prospectus is part of a registration statement filed with the Securities and Exchange Commission, or the SEC, utilizing a shelf registration process. Under this shelf registration process, we may sell any combination of the securities described in this prospectus, either individually or in units, in one or more offerings, up to a total dollar amount of $12,000,000.
 
This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that specific offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read this prospectus and the applicable prospectus supplement together with the additional information described under the heading “Where You Can Find More Information.”
 
We have not authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus, any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and any applicable prospectus supplement to this prospectus is accurate as of the date on the respective covers of such documents, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, regardless of the time of delivery of this prospectus, such prospectus supplement, or any sale or issuance of a security, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed materially since those dates. You should rely only on the information contained or incorporated by reference in this prospectus or any accompanying prospectus supplement.
 
Unless the context otherwise requires, all references to “Solitario,” “the Company,” “we,” “our,” “us” or “our company” in this prospectus refer to Solitario Zinc Corp., a Colorado corporation.
 
ABOUT SOLITARIO ZINC CORP.
 
Solitario is an exploration stage company under Industry Guide 7, as issued by the SEC, with a focus on the acquisition of precious and base metal properties with exploration potential and the development or purchase of royalty interests. Currently our primary focus is the acquisition and exploration of zinc-related exploration mineral properties. However, we continue to evaluate other mineral properties for acquisition. We acquire and hold a portfolio of exploration properties for future sale, joint venture, or to create a royalty prior to the establishment of proven and probable reserves. Although our mineral properties may be developed in the future by us, through a joint venture or by a third party, we have never developed a mineral property.
 
Our current geographic focus for the evaluation of potential mineral property assets is in North and South America; however, we have conducted property evaluations for potential acquisition in other parts of the world. We currently consider our carried interest in the Florida Canyon project in Peru and our interest in the Lik project in Alaska to be our core mineral property assets. In addition, we have one other exploration property in Peru. We are conducting independent exploration activities on our own and through joint ventures operated by our partners in Peru and the United States.
 
 We are exploring other mineral properties that may be developed in the future by us or through a joint venture. We may also evaluate mineral properties to potentially buy a royalty.
 
We have been actively involved in mineral exploration since 1993. We have recorded revenue in the past from the sale of mineral properties, including from a royalty in January 2019 and the sale in June 2018 of our interest in the royalty on the Yanacocha property. Future revenues from the sale of properties or royalty interests, if any, will likely occur on an infrequent basis (if at all). Historically we have reduced our exposure to the costs of our exploration activities through the use of joint ventures. Although we anticipate that the use of joint venture funding for some of our exploration activities will continue for the foreseeable future, we can provide no assurance that these or other sources of capital will be available in sufficient amounts to meet our needs, if at all.

Corporate Information
 
We were incorporated in Colorado on November 15, 1984 under the name Solitario Resources Corporation as a wholly-owned subsidiary of Crown Resources Corporation, or Crown. On June 12, 2008, our shareholders approved an amendment to the Articles of Incorporation to change our name from Solitario Resources Corporation to Solitario Exploration & Royalty Corp. In July 1994, Solitario became a publicly traded company on the Toronto Stock Exchange through its initial public offering. On July 26, 2004, Crown completed a spin-off of its holdings of our shares to its shareholders as part of the acquisition of Crown by Kinross Gold Corporation. In July 2017 Solitario acquired Zazu Metals Corp. and its 50% interest in the Lik project in Alaska and changed its name to Solitario Zinc Corp. from Solitario Exploration & Royalty Corp.

RISK FACTORS
 
Investing in our securities involves a high degree of risk. Please see the risk factors under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019, on file with the SEC, and those risk factors identified in reports subsequently filed with the SEC, including our Quarterly Report on Form 10-Q for the quarter ended June 30, 2020, which are incorporated by reference into this prospectus. Before you invest in our securities, you should carefully consider these risks as well as other information we include or incorporate by reference into this prospectus and the applicable prospectus supplement. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. The discussion of risks includes or refers to forward-looking statements; you should read the explanation of the qualifications and limitations on such forward-looking statements discussed elsewhere in this prospectus.
 
FORWARD-LOOKING STATEMENTS
 
This prospectus contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including any projections of financing needs, revenue, expenses, earnings or losses from operations, or other financial items; any statements of the plans, strategies and objectives of management for future operations; any statements concerning exploration and development plans and timelines; any statements of expectation or belief; any statements regarding the impact to our business from the COVID-19 global crisis; and any statements of assumptions underlying any of the foregoing. In addition, forward looking statements may contain the words “believe,” “anticipate,” “expect,” “estimate,” “intend,” “plan,” “project,” “will be,” “will continue,” “will result,” “seek,” “could,” “may,” “might,” or any variations of such words or other words with similar meanings.
 
The forward-looking statements included in this prospectus represent our estimates as of the date of this prospectus. We specifically disclaim any obligation to update these forward-looking statements in the future, except as required by law. These forward-looking statements should not be relied upon as representing our estimates or views as of any date subsequent to the date of this prospectus.
 
RATIOS OF EARNINGS TO FIXED CHARGES
 
If we offer debt securities and/or preference equity securities under this prospectus, then we will, at that time, and if required by the rules promulgated by the SEC, provide a ratio of earnings to fixed charges and/or ratio of combined fixed charges and preference dividends to earnings, respectively, in the applicable prospectus supplement for such offering.

HOW WE INTEND TO USE THE PROCEEDS
 
Unless otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities under this prospectus to fund exploration and development of our mineral properties, and for general corporate purposes, including capital expenditures and working capital. We may use a portion of our net proceeds to invest in or acquire additional mineral property assets or royalty interests. We will set forth in the prospectus supplement our intended use for the net proceeds received from the sale of any securities. Pending the application of the net proceeds, we intend to invest the net proceeds in investment-grade, interest-bearing securities.
 
DESCRIPTION OF THE SECURITIES
 
We may offer, from time to time, in one or more offerings, up to $12,000,000 of the following securities:
 
common stock;
 
preferred stock;
 
senior debt securities;
 
subordinated debt securities;
 
warrants;
 
rights;
 
units; or
 
any combination of the foregoing securities.
 
The aggregate initial offering price of the offered securities that we may issue will not exceed $12,000,000. Until such time as the aggregate market value of the voting and non-voting common equity held by non-affiliates of the Company is $75 million or more, the aggregate market value of securities sold by or on behalf of the Company pursuant to this registration statement during the period of 12 calendar months immediately prior to, and including, a sale under this registration statement will be no more than one-third of the aggregate market value of the voting and non-voting common equity held by non-affiliates of the Company. If we issue debt securities at a discount from their principal amount, then, for purposes of calculating the aggregate initial offering price of the offered securities issued under this prospectus, we will include only the initial offering price of the debt securities and not the principal amount of the debt securities.
 
This prospectus contains a summary of the general terms of the various securities that we may offer. The prospectus supplement relating to any particular securities offered will describe the specific terms of the securities, which may be in addition to or different from the general terms summarized in this prospectus. Because the summary in this prospectus and in any prospectus supplement does not contain all of the information that you may find useful, you should read the documents relating to the securities that are described in this prospectus or in any applicable prospectus supplement. Please read “Where You Can Find More Information” to find out how you can obtain a copy of those documents.
 
The applicable prospectus supplement will also contain the terms of a given offering, the initial offering price and our net proceeds. Where applicable, a prospectus supplement will also describe any material United States federal income tax consequences relating to the securities offered and indicate whether the securities offered are or will be quoted or listed on any quotation system or securities exchange.
 
DESCRIPTION OF COMMON STOCK
 
The following summary of certain rights and terms of our common stock does not purport to be complete. You should refer to our Articles, and our By-laws, both of which are included as exhibits to the registration statement we have filed with the SEC in connection with this offering. The summary below is also qualified by provisions of applicable law.
 

3
 
 
General Terms
 
We are authorized to issue 100,000,000 shares of common stock. On September 28, 2020, we had 58,107,466 shares of common stock outstanding and approximately 3,200 stockholders of record. Except as otherwise provided by any series of preferred stock that may later be created, holders of our common stock have exclusive voting rights for the election of directors and for all other purposes. Holders of our common stock are entitled to one vote per share on all matters to be voted upon by our stockholders. Neither our Articles nor our By-laws authorize cumulative voting. The holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of funds legally available for the payment of dividends, subject to the rights of any series of preferred stock. In the event of a liquidation, dissolution or winding up of Solitario, the holders of our common stock are entitled to share ratably in all assets remaining after payment of the preferential amounts, if any, to which the holders of our preferred stock, if any, are entitled. Our common stock has no preemptive, conversion or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. All of our outstanding shares of common stock are fully paid and non-assessable.
 
Our Board of Directors
 
Our board of directors currently has six members. Our Articles and our By-laws provide that the number of directors shall be fixed from time to time by resolution adopted by the vote of a majority of the directors then in office, but shall in no event be less than three (except that there need be only as many directors as there are stockholders in the event the outstanding shares are held of record by fewer than three stockholders) nor more than nine. Our Articles provide that, upon the first election of directors by the stockholders after an increase in the number of directors to nine or more, the board of directors shall be divided into three nearly equal classes, with each classes’ term expiring on a staggered basis. Vacancies and newly created directorships may be filled by a majority of the directors then in office, though less than a quorum. Directors may be removed with or without cause by the affirmative vote of a majority of the outstanding shares of capital stock entitled to vote generally in the election of directors cast at a meeting of the stockholders called for that purpose. If a director is elected by a voting group of stockholders, only the stockholders of that voting group may participate in the vote to remove that director.
 
Transfer Agent and Registrar
 
The transfer agent and registrar for our common stock in the United States is Computershare Trust Company, N.A. and in Canada is Computershare Investor Services Inc.
 
NYSE MKT and Toronto Stock Exchange
 
Our common stock is listed for quotation on the NYSE MKT under the symbol “XPL” and on the Toronto Stock Exchange under the symbol “SLR.”
 
DESCRIPTION OF PREFERRED STOCK
 
We are authorized to issue 10,000,000 shares of preferred stock. As of the date of this prospectus, no shares of our preferred stock were outstanding. The following summary of certain provisions of our preferred stock does not purport to be complete. You should refer to our Amended and Restated Articles of Incorporation, as amended, or the Articles, and our amended and restated by-laws, or the By-laws, both of which are included as exhibits to the registration statement we have filed with the SEC in connection with this offering. The summary below is also qualified by provisions of applicable law.
 
General Terms
 
Our board of directors may, without further action by our stockholders, from time to time, direct the issuance of shares of preferred stock in series and may, at the time of issuance, determine the rights, preferences and limitations of each series, including voting rights, dividend rights and redemption and liquidation preferences. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of our common stock (although we do not anticipate paying any dividends to the holders of our common stock in the foreseeable future). Holders of shares of preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of our company before any payment is made to the holders of shares of our common stock. In some circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management as discussed below. Upon the affirmative vote of our board of directors, without stockholder approval, we may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of our common stock.

If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the articles of amendment to the Articles establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:
 
the title and stated value;
 
the number of shares offered, the liquidation preference per share and the purchase price;
 
the dividend rate(s), period(s) and/or payment date(s), or method(s) of calculation for such dividends;

voting rights, if any, of the preferred stock;
 
a discussion of any material and/or special United States federal income tax considerations applicable to the preferred stock;
 
the relative ranking and preferences of the preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of the affairs of Solitario; and
 
any material limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of Solitario.
 
The preferred stock offered by this prospectus will, when issued, not have, or be subject to, any preemptive or similar rights.
 
Transfer Agent and Registrar
 
The transfer agent and registrar for our preferred stock in the United States will be Computershare Trust Company, N.A. and in Canada will be Computershare Investor Services Inc.

As of the date of this prospectus, we have no outstanding registered debt securities.
 
DESCRIPTION OF WARRANTS
 
As of the date of this prospectus, no warrants to purchase shares of our common stock, preferred stock and/or debt securities were outstanding. We may issue warrants to purchase shares of our common stock, preferred stock, debt securities and / or other securities in one or more series together with other securities or separately, as described in the applicable prospectus supplement. Below is a description of certain general terms and provisions of the warrants that we may offer. Particular terms of the warrants will be described in the warrant agreements and the prospectus supplement to the warrants.
 
The applicable prospectus supplement will contain, where applicable, the following terms of and other information relating to the warrants:
 
the specific designation and aggregate number of, and the price at which we will issue, the warrants;
 
the currency or currency units in which the offering price, if any, and the exercise price are payable;
 
the designation, amount and terms of the securities purchasable upon exercise of the warrants;
 
if applicable, the exercise price for shares of our common stock and the number of shares of common stock to be received upon exercise of the warrants;
 
if applicable, the exercise price for shares of our preferred stock, the number of shares of preferred stock to be received upon exercise, and a description of that series of our preferred stock;
 
if applicable, the exercise price for our debt securities, the amount of debt securities to be received upon exercise, and a description of that series of debt securities;
 
the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;
 
whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;
 

7
 
 
any applicable material United States federal income tax consequences;

the proposed listing, if any, of the warrants or any securities purchasable upon exercise of the warrants on any securities exchange;
 
if applicable, the date from and after which the warrants and the common stock, preferred stock and/or debt securities will be separately transferable;
 
if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;
 
information with respect to book-entry procedures, if any;
 
the anti-dilution provisions of the warrants, if any;
 
any redemption or call provisions;
 
whether the warrants are to be sold separately or with other securities as parts of units; and
 
any additional terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.
 
Exercise of Warrants
 
Each warrant will entitle the holder to purchase for cash that principal amount of, or number of, securities, as the case may be, at the exercise price set forth in, or to be determined as set forth in, the applicable prospectus supplement relating to the warrants. After the close of business on the expiration date, unexercised warrants will become void. Upon receipt of payment and the warrant certificate properly completed and duly executed, we will, as soon as practicable, issue the securities purchasable upon exercise of the warrant. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining amount of warrants.
 
No Rights of Security Holder Prior to Exercise
 
Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon the exercise of the warrants, and will not be entitled to:
 
in the case of warrants to purchase debt securities, payments of principal of, or any premium or interest on, the debt securities purchasable upon exercise; or
 
in the case of warrants to purchase equity securities, the right to vote or to receive dividend payments or similar distributions on the securities purchasable upon exercise.
 
Transfer Agent and Registrar
 
The transfer agent and registrar for any warrants will be set forth in the applicable prospectus supplement.
 
DESCRIPTION OF RIGHTS
 
As specified in the applicable prospectus supplement, we may issue rights to purchase the securities offered in this prospectus to our existing stockholders, and such rights may or may not be issued for consideration. The applicable prospectus supplement will describe the terms of any such rights. The description in the prospectus supplement will not purport to be complete and will be qualified in its entirety by reference to the documents pursuant to which such rights will be issued.
 
DESCRIPTION OF UNITS
 
This section outlines some of the provisions of the units and the unit agreements. This information may not be complete in all respects and is qualified entirely by reference to the unit agreement with respect to the units of any particular series. The specific terms of any series of units will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any series of units may differ from the general description of terms presented below.
 
We may issue units comprised of shares of preferred stock, shares of common stock, warrants and debt securities in any combination. Each unit will be issued 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 a unit is issued 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.
 

8
 
 
The applicable prospectus supplement may describe:
 
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;
 
the price or prices at which such units will be issued;
 
the applicable United States federal income tax considerations relating to the units;
 
any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and
 
any other terms of the units and of the securities comprising the units.
 
The provisions described in this section, as well as those described under “Description of Preferred Stock,” “Description of Common Stock,” “Description of Warrants”, “Description of Debt Securities”, and “Description of Rights” will apply to the securities included in each unit, to the extent relevant.
 
Issuance in Series
 
We may issue units in such amounts and in as many distinct series as we wish. This section summarizes terms of the units that apply generally to all series. Most of the financial and other specific terms of your series will be described in the applicable prospectus supplement.
 
Unit Agreements
 
We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the applicable prospectus supplement.
 
The following provisions will generally apply to all unit agreements unless otherwise stated in the applicable prospectus supplement.
 
Modification Without Consent
 
We and the applicable unit agent may amend any unit or unit agreement without the consent of any holder:
 
to cure any ambiguity; any provisions of the governing unit agreement that differ from those described below;
 
to correct or supplement any defective or inconsistent provision; or
 
to make any other change that we believe is necessary or desirable and will not adversely affect the interests of the affected holders in any material respect.
 
We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.
 
Modification With Consent
 
We may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:
 
impair any right of the holder to exercise or enforce any right under a security included in the unit if the terms of that security require the consent of the holder to any changes that would impair the exercise or enforcement of that right; or
 
reduce the percentage of outstanding units or any series or class the consent of whose holders is required to amend that series or class, or the applicable unit agreement with respect to that series or class, as described below.
 
 

9
 
 
Any other change to a particular unit agreement and the units issued under that agreement would require the following approval:
 
If the change affects only the units of a particular series issued under that agreement, the change must be approved by the holders of a majority of the outstanding units of that series; or
 
If the change affects the units of more than one series issued under that agreement, it must be approved by the holders of a majority of all outstanding units of all series affected by the change, with the units of all the affected series voting together as one class for this purpose.
 
These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document.
 
In each case, the required approval must be given by written consent.
 
Unit Agreements Will Not Be Qualified Under Trust Indenture Act
 
No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act with respect to their units.
 
Mergers and Similar Transactions Permitted; No Restrictive Covenants or Events of Default
 
The unit agreements will not restrict our ability to merge or consolidate with, or sell our assets to, another corporation or other entity or to engage in any other transactions. If at any time we merge or consolidate with, or sell our assets substantially as an entirety to, another corporation or other entity, the successor entity will succeed to and assume our obligations under the unit agreements. We will then be relieved of any further obligation under these agreements.
 
The unit agreements will not include any restrictions on our ability to put liens on our assets, including our interests in our subsidiaries, nor will they restrict our ability to sell our assets. The unit agreements also will not provide for any events of default or remedies upon the occurrence of any events of default.
 
Payments and Notices
 
In making payments and giving notices with respect to our units, we will follow the procedures as described in the applicable prospectus supplement.
 
FORMS OF SECURITIES
 
General
 
Each of the securities issued under this prospectus will be represented either by a certificate issued in definitive form to a particular purchaser or by one or more global securities representing the entire issuance of securities. Unless the applicable prospectus supplement provides otherwise, certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, units or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each purchaser's beneficial ownership of the securities through an account maintained by the purchaser with its broker/dealer, bank, trust company or other representative, as we explain more fully below.
 
10
 
 
Registered Global (Book-Entry) Securities
 
We may issue the securities in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.
 
 If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.
 
Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair such purchasers' abilities to own, transfer or pledge beneficial interests in registered global securities.
 
So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, unit agreement or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, unit agreement or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, unit agreement or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, unit agreement or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.
 
Principal, premium, if any, on and interest payments on debt securities, and any payments to holders with respect to warrants or units represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustees, the warrant agents, the unit agents or any other agent of ours, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.
 
We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers or registered in "street name," and will be the responsibility of those participants.
 
11
 
 
If the depositary for any of the securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, or Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary's instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.
 
PLAN OF DISTRIBUTION
 
We may sell the securities in any one or more of the following methods from time to time:
 
directly to investors, directly to agents, or to investors through agents;
 
through underwriting syndicates led by one or more managing underwriters, or through one or more underwriters acting alone, for resale to the public or investors;
 
purchases by a broker or dealer as principal and resale by such broker or dealer for its own account;
 
through a block trade (which may involve crosses) in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
 
ordinary brokerage transactions and transactions in which the broker solicits purchasers;
 
in “at the market offerings,” within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;
 
transactions not involving market makers or established trading markets, including direct sales or privately negotiated transactions;
 
exchange distributions and/or secondary distributions;
 
by delayed delivery contracts or by remarketing firms;
 
transactions in options, swaps or other derivatives that may or may not be listed on an exchange; or
 
through a combination of any such methods of sale.
 
The distribution of the securities may be effected from time to time in one or more transactions:
 
at a fixed price or prices, which may be changed;
 
at market prices prevailing at the time of sale;
 
at prices related to such prevailing market prices; or
 
at negotiated prices.
 
Any of the prices may represent a discount from the prevailing market prices.
 
Any underwritten offering may be on a best efforts or a firm commitment basis. If underwriters are used in the sale, the securities acquired by the underwriters will be for their own account. The underwriters may resell the securities in one or more transactions, including without limitation negotiated transactions, at a fixed public offering price or at a varying price determined at the time of sale. The obligations, if any, of the underwriter to purchase any securities will be subject to certain conditions. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities if any are purchased, other than securities covered by any over-allotment option. Any public offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.
 
If a dealer is used in an offering of securities, we may sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of sale.
 

12
 
 
We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.
 
We may also sell securities directly to one or more purchasers without using underwriters, dealers or agents.
 
We may also make direct sales through subscription rights distributed to our stockholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to stockholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties.
 
From time to time, we may offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, and may use the Internet or another electronic bidding or ordering system for the pricing and allocation of the securities. Such a system may allow bidders to participate directly, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and may directly affect the price or other terms at which such securities are sold. Such a bidding or ordering system may present to each bidder, on a real-time basis, relevant information to assist you in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, pro-rated or rejected. Other pricing methods also may be used. Upon completion of such an auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet bidding process or auction. Many variations of the Internet auction or pricing and allocation systems are likely to be developed in the future, and we may use such systems in connection with the sale of securities. The specific rules of such an auction would be distributed to potential bidders in an applicable prospectus supplement. If an offering is made using such a bidding or ordering system you should review the auction rules, as described in the prospectus supplement, for a more detailed description of the offering procedures.
 
In the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities may be deemed to be underwriters under the Securities Act and any discounts or commissions they receive from us and any profit on the resale of securities they realize may be deemed to be underwriting discounts and commissions under the Securities Act. The applicable prospectus supplement will, where applicable:
 
identify any such underwriter or agent;
 
describe any compensation in the form of discounts, concessions, commissions or otherwise received from us by each of such underwriter, dealer or agent and in the aggregate to all underwriters, dealers and agents;
 
identify the purchase price and proceeds from such sale;
 
identify the amounts underwritten;
 
identify the nature of the underwriter’s obligation to take the securities;
 
identify any over-allotment option under which the underwriters may purchase additional securities from us; and
 
identify any quotation systems or securities exchanges on which the securities may be quoted or listed.
 
Unless otherwise specified in the related prospectus supplement, each series of securities will be a new issue with no established trading market, other than the common stock, which is listed on the NYSE MKT and the Toronto Stock Exchange. Any common stock sold pursuant to a prospectus supplement will be listed on the NYSE MKT and the Toronto Stock Exchange, subject to applicable notices. We may elect to apply for quotation or listing of any other class or series of our securities, on a quotation system or an exchange but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, no assurance can be given as to the liquidity of, or the trading market for, any other class or series of our securities.
 

13
 
 
In connection with an offering, an underwriter may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional securities, if any, from us in the offering. If the underwriters have an over-allotment option to purchase additional securities from us, the underwriters may close out any covered short position by either exercising their over-allotment option or purchasing securities in the open market. In determining the source of securities to close out the covered short position, the underwriters may consider, among other things, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotment option. “Naked” short sales are any sales in excess of such option or where the underwriters do not have an over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.
 
Accordingly, to cover these short sales positions or to otherwise stabilize or maintain the price of the securities, the underwriters may bid for or purchase securities in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The impositions of a penalty bid may also affect the price of the securities to the extent that it discourages resale of the securities. The magnitude or effect of any stabilization or other transactions is uncertain. These transactions may be effected on the NYSE MKT or otherwise and, if commenced, may be discontinued at any time.
 
We do not make any representation or prediction as to the direction or magnitude of any effect that the transactions described above might have on the price of the securities. In addition, we do not make any representation that underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice at any time.
 
Under agreements into which we may enter, underwriters, dealers and agents who participate in the distribution of the securities may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or contribution from us to payments which the underwriters, dealers or agents may be required to make.
 
Underwriters, dealers and agents may engage in transactions with us or perform services for us in the ordinary course of business.
 
If indicated in the applicable prospectus supplement, securities may also be offered or sold by a “remarketing firm” in connection with a remarketing arrangement contemplated by the terms of the securities. Remarketing firms may act as principals for their own accounts or as agents. The applicable prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us. It will also describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the remarketing of the securities.
 
If indicated in the applicable prospectus supplement, we will authorize underwriters, dealers or other persons acting as our agents to solicit offers by particular institutions to purchase securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on such future date or dates stated in such prospectus supplement. Each delayed delivery contract will be for an amount no less than, and the aggregate principal amounts of securities sold under delayed delivery contracts shall be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Institutions with which such delayed delivery contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but will in all cases be subject to our approval. The obligations of any purchaser under any such contract will be subject to the conditions that (1) the purchase of the securities shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject, and (2) if the securities are being sold to underwriters, we shall have sold to the underwriters the total principal amount of the securities less the principal amount thereof covered by the delayed delivery contracts. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such delayed delivery contracts.
 
With respect to the sale of any securities under this prospectus, the maximum compensation to be received by any member of the Financial Industry Regulatory Authority, Inc. or independent broker or dealer is not expected to be greater than eight percent (8%).
 
To comply with applicable state securities laws, the securities offered by this prospectus will be sold, if necessary, in such jurisdictions only through registered or licensed brokers or dealers. In addition, securities may not be sold in some states unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

CERTAIN PROVISIONS OF COLORADO LAW AND OF OUR
ARTICLES AND BY-LAWS
 
Anti-Takeover Provisions of our Articles and By-laws
 
In addition to the board of directors’ ability to issue shares of preferred stock, our Articles and our By-laws contain other provisions that are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of our company unless such takeover or change in control is approved by our board of directors. These provisions include the possibility of a classified board of directors as discussed above in “Description of Common Stock – Our Board of Directors” and advance notice procedures for stockholder proposals.
 
Classified Board. The provision for a classified board could prevent a party who acquires control of a majority of our outstanding common stock from obtaining control of the board until our second annual stockholders meeting following the date the acquirer obtains the controlling stock interest. The classified board provision could have the effect of discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us and could increase the likelihood that incumbent directors will retain their positions.
 
Advance Notice Procedures for Stockholder Proposals. Our By-laws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board. Stockholders at our annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given to our secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Although our By-laws do not give our board the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, our By-laws may have the effect of precluding the conduct of some business at a meeting if the proper procedures are not followed or may discourage or defer a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of us.
 
Limitations on Liability and Indemnification of Officers and Directors
 
Our Articles limit the liability of our directors to the fullest extent permitted by Colorado law and provide that we are authorized to indemnify them to the fullest extent permitted by such law. Our By-laws provide that we are authorized to indemnify our officers to the fullest extent permitted by Colorado law.
 
INFORMATION INCORPORATED BY REFERENCE
 
The SEC allows us to incorporate by reference the information and reports we file with it, which means that we can disclose important information to you by referring you to these documents.
