ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement is a part of a registration statement on Form S-3 (File No. 333-288922) that we filed with the Securities and Exchange Commission (“SEC”) using a shelf registration process.

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements provide our current expectations or forecasts of future events and are not statements of historical fact. These forward-looking statements relate to, among other things: our businesses and prospects and our overall strategy; the progress, potential and uncertainties of the Company’s exploration program; our planned exploration activities across our portfolio of exploration targets; our planned or estimated capital expenditures for exploration and general and administrative costs; government regulations, including our ability to obtain, and the timing of, necessary government permits and approvals; expectations regarding the availability of our liquidity and capital resources, and our ability to scale down spending if sufficient resources are not available; our ability to obtain financing as needed and the terms of such financing transactions; progress in developing our projects and the timing of that progress; and attributes and future values of the Company’s projects or other interests, operations or rights. These forward-looking statements are not historical facts but are the intent, belief or current expectations of our management based on its knowledge and understanding of our business and industry. Forward-looking statements are typically identified by the use of terms such as “anticipate,” “assume,” “believe,” “budget,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “forecast,” “initial,” “intend,” “likely,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “proposed,” “should,” “will,” “would” or the negative of such terms and variations of these words and similar expressions, although not all forward-looking statements include these words. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements.

Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. You are cautioned not to place undue reliance on forward-looking statements. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results. Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors which could cause actual events or results to differ from those expressed or implied by the forward-looking statements, including, without limitation:

•

lack of defined mineral reserve estimates prepared in accordance with Subpart 1300 of Regulation S-K (“S-K 1300”);

•

the failure to successfully execute management’s strategy and manage our growth;

•

our limited operating history and history of losses, including the potential for future losses;

•

uncertainty as to future production at our mineral exploration and development properties;

•

our ability to maintain sufficient liquidity and attract sufficient capital resources to implement our projects;

•

ownership of surface rights at our Black Hills Property;

•

mining exploration and development risks, including risks related to regulatory approvals, operational hazards and accidents, equipment breakdowns, labor and contractor disputes, contractual disputes related to exploration properties, unanticipated or increased operating costs and other unanticipated difficulties;

•

potential health risks associated with mining and mineral exploration;

•

fluctuations in commodity prices;

•

future adverse legislation regarding the mining industry and climate change;

•

uncertainties associated with potential litigation matters, including environmental lawsuits;

•

our land reclamation requirements;

S-v

TABLE OF CONTENTS

•

our ability to maintain the adequacy of internal control over financial reporting;

•

adverse technological changes and cybersecurity threats;

•

title in our properties;

•

competition in the gold and silver mining industries;

•

economic and financial conditions, including volatility in interest and exchange rates, commodity and equity prices and the value of financial assets;

•

economic uncertainty and market volatility due to potential new tariffs on imported and exported goods;

•

our ability to attract and retain key management and mining personnel necessary to successfully operate and grow our business; and

•

volatility in the market price of our listed securities.

This list is not exhaustive of the factors that may affect our forward-looking statements. Although we have attempted to identify important factors that could cause actual results to differ materially from those described in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made.

The forward-looking statements should be read in light of these factors and the factors identified in “Item 1A. Risk Factors” incorporated by reference into this prospectus supplement and the accompanying prospectus from our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other reports and information that we file with the SEC.

Overview

We are engaged in the business of acquisition and exploration of mineral properties within the Homestake Gold District of the Black Hills of South Dakota.

Our management and technical teams have extensive mining and exploration experience, much of it in the Homestake District, and we intend to leverage our experience together with our business presence in South Dakota to create value for our stakeholders.

TABLE OF CONTENTS

RISK FACTORS

Investing in our common stock involves a high degree of risk. Please see the risks described below in addition to the risk factors included in our most recent Annual Report on Form 10-K, as updated and supplemented from time to time, and in our subsequent Quarterly Reports on Form 10-Q and other information that we file from time to time with the SEC. Such risks are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect us and the market value of our common stock. The risks described could affect our business, financial condition, liquidity, results of operations, prospects, and the market value of our common stock. In such a case, you may lose all or part of your original investment. You should consider carefully the risks described below and in our Annual Report on Form 10-K and any subsequent Quarterly Reports filed on Form 10-Q, as well as other information and data set forth in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein before making an investment decision with respect to our common stock.

Risks Related to This Offering

You may lose some or all of your investment in the Company.

An investment in our common stock is speculative and may result in the loss of an investor’s entire investment. Only potential investors who are experienced in high risk investments and who can afford to lose their entire investment should consider an investment in the Company.

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our senior management will have broad discretion in the application of the net proceeds from this offering. Because of the number and variability of factors that will determine our use of the net proceeds, their ultimate use may vary substantially from their currently intended use. Our senior management might not apply our net proceeds in ways that ultimately increase the value of your investment. While we expect to use the net proceeds from this offering as set forth in “Use of Proceeds,” we are not obligated to do so. The failure by our management to apply these funds effectively could harm our business. If we do not invest or apply the net proceeds in ways that enhance stockholder value, we may fail to achieve expected financial results, which could adversely affect our business, financial condition and results of operations, and cause the price of our shares of common stock to decline.

You may experience future dilution as a result of future equity offerings.

To raise additional capital, we may in the future offer additional shares of common stock or other securities convertible into or exchangeable for common stock at prices that may not be the same as the price per share in this offering. We may sell common stock or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

Trading in our common stock on the NYSE American is volatile.

Our common stock is currently quoted on the NYSE American. The trading price of our common stock has been subject to wide fluctuations. Trading prices of our common stock may fluctuate in response to a number of factors, many of which will be beyond our control. In addition to other risk factors identified in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein and due to volatility associated with equity securities in general, the value of a stockholder’s investment could decline due to the impact of numerous factors upon the market price of our common stock, including:

•

changes in the worldwide price for the metals we intend to mine;

•

adverse results from our exploration, development, or production efforts;

•

producing at rates lower than those targeted;

S-3

TABLE OF CONTENTS

•

political and regulatory risks and social unrest, including geopolitical conflicts;

•

weather conditions and extreme weather events, including unusually heavy rains;

•

failure to meet our revenue or profit goals or operating budget;

•

decline in demand for our common stock;

•

downward revisions in securities analysts’ estimates or changes in global financial markets and global economies and general market conditions;

•

technological innovations by competitors or in competing technologies;

•

investor perception of our industry or our prospects;

•

lawsuits;

•

economic impact from spread of disease

•

our ability to integrate and operate the companies and the businesses that we acquire;

•

interest rate levels and expectations of future changes in interest rates;

•

actions by government or central banks;

•

general economic trends; and

•

the other factors discussed under “Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K for the year ended December 31, 2024 and other documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

The stock market has generally experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies in the development stage. There can be no assurance that trading prices previously experienced by our common stock will be matched or maintained. These broad market and industry factors may adversely affect the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted. Such litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources.

Sales of a significant number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock.

We cannot predict the size of future sales and issuances of debt or equity securities or the effect, if any, that future sales and issuances of debt or equity securities will have on the market price of our common stock. Sales of a substantial number of shares of our common stock in the public markets, or the perception that such sales could occur, could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities.

We cannot predict the effect that future sales of our common stock would have on the market price of our common stock. The price of our common stock could be affected by possible sales of our common stock by hedging or arbitrage trading activity. With any additional sale or issuance of equity securities, investors will suffer dilution of their voting power and may experience dilution in our earnings per share.

We have never paid cash dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future.

We have never paid cash dividends on any of our capital stock and we currently intend to retain any future earnings to fund the growth of our business. Any determination to pay dividends in the future will be at the discretion of our board of directors and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that the board may deem relevant. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.

The underwriters are committed to purchase all the shares of our common stock offered by us if they purchase any shares of our common stock. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters are purchasing our common stock at a price of $ per share. The underwriters initially propose to offer our common stock to the public at the offering price listed on the cover of this prospectus supplement. After the initial offering of our common stock, the applicable offering price and other selling terms may from time to time be varied by the underwriters at any time and without notice. The difference between the price at which the underwriter purchases the shares of our common stock and the price at which the underwriters resell such shares may be deemed underwriting compensation. Pursuant to the underwriting agreement, the underwriters also have the right to arrange for a portion of the shares of our common stock to be purchased by substituted purchasers in certain Canadian selling jurisdictions pursuant to a private placement in compliance with Canadian securities laws.

The underwriters have an option to buy up to additional shares of our common stock from us. The underwriters have 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares of our common stock. If any shares are purchased with this option to purchase additional shares of our common stock, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of our common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares of our common stock are being offered.

Our directors and executive officers (such parties, the “lock-up parties”) have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which we and each of these persons, during the lock-up period, may not, without the prior written consent of the representatives, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the SEC in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any shares of our common stock or any other securities that are substantially similar to our common stock, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing (collectively, the “lock-up securities”), (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the lock-up securities, whether any such transaction is to be settled by delivery of the shares of our common stock or such other securities, in cash or otherwise or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii).

The restrictions described in the immediately preceding paragraph and contained in the lock-up agreements between the underwriters and the lock-up parties do not apply, subject in certain cases to various conditions, to certain transactions, including (a) any sale, transfer or tender of any of the lock-up parties’ shares of common stock to a take-over bid or in connection with a merger, business combination, arrangement, restructuring or similar transaction involving a change of control of us that is approved by our board of directors, provided that in the event such transaction is not completed the lock-up parties’ shares of common stock shall continue to be subject to the foregoing restrictions; (b) transfers to affiliates of the lock-up parties, any family members of the lock-up parties, or any company, trust or other entity owned by or maintained for the benefit of the lock-up parties, provided in each case the recipient thereof agrees in writing with the Underwriters to be bound by the foregoing restrictions; (c) any transfers, sales or other dispositions of shares of common stock pursuant to any contract, instruction or plan, including a contract, instruction or plan complying with Rule 10b5-1 of the Exchange Act that has been entered into by the lock-up parties prior to the date of the lock-up agreements; (d) any sale to us or withholding of any shares to the us to cover taxes in connection with the vesting or issuance of shares, restricted share units, or other equity awards granted under our equity incentive plans; or (e) any transactions necessary to cover taxes in connection with the vesting or issuance of shares, restricted share units, or other equity awards granted under our equity incentive plans outstanding as of the date of this prospectus supplement, so long as such sale is limited to the number of shares necessary to cover the exercise price of such award and any applicable withholding tax obligation resulting from such exercise or vesting, provided that the aggregate amount of the securities to which such sales, distributions and dispositions of securities pursuant to this clause (f) relate shall not exceed 1,067,808, provided further that in the case of any transfer or distribution pursuant to clause (b), (c), (d) or (e), it shall be a condition to such transfer that no public filing, report or announcement shall be voluntarily made and if any

filing under Section 16(a) of the Exchange Act, or other public filing, report or announcement reporting a reduction in beneficial ownership of shares of common stock in connection with such transfer or distribution shall be legally required during the lock-up period, such filing, report or announcement shall clearly indicate in the footnotes thereto the nature and conditions of such transfer.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act and civil liabilities under Canadian securities legislation.

Our shares of common stock are listed on the NYSE American under the symbol “DC.”

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling of shares of our common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of shares of our common stock, which involves the sale by the underwriters of a greater number of shares than they are required to purchase in this offering, and purchasing shares of our common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares of our common stock, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of our common stock available for purchase in the open market compared to the price at which the underwriters may purchase shares of our common stock through the option to purchase additional shares. 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 our common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares of our common stock in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of our common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase shares of our common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities 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 our common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on any stock exchange on which our common stock is listed, in the over-the-counter market or otherwise.

A prospectus supplement in electronic format may be made available on websites maintained by the underwriter, or selling group members, if any, participating in this offering.

U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax considerations generally applicable to the ownership and disposition of our common stock by a non U.S. holder (as defined below). This discussion is based on currently existing provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof and all of which are subject to change or to differing interpretation, possibly with retroactive effect. Accordingly, the U.S. federal income tax considerations applicable to the ownership and disposition of our common stock by a non U.S. holder could differ from those described below.

For purposes of this discussion, a “non U.S. holder” is a beneficial owner of our common stock that is not, for U.S. federal income tax purposes, any of the following:

•

a citizen or individual resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state or political subdivision thereof;

•

any entity or arrangement treated as a partnership for U.S. federal income tax purposes;

•

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to (A) the primary supervision of a court within the United States and (B) the authority of one or more U.S. persons to control all substantial decisions of the trust, or (2) has a valid election in effect to be treated as a U.S. person.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner (or other beneficial owner) will generally depend upon the status of the partner (or other beneficial owner) and the activities of the partnership. Any entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds our common stock, and any owners of such an entity or arrangement, should consult their own tax advisors regarding the tax considerations applicable to an investment in our common stock.

This discussion applies only to non-U.S. holders of our common stock who hold such common stock as a “capital asset” within the meaning of the Code (generally, property held for investment). This discussion does not address the applicability of the alternative minimum tax or the Medicare tax on net investment income, any U.S. federal estate or gift tax, or foreign, state or local tax considerations applicable to the ownership and disposition of our common stock. In addition, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders of our common stock in light of their particular circumstances, nor does it address the U.S. federal income tax considerations applicable to non-U.S. holders of our common stock that are subject to special rules, including, without limitation:

•

tax-exempt organizations;

•

banks and certain other financial institutions;

•

retirement plans;

•

banks, insurance companies, and other financial institutions;

•

mutual funds;

•

regulated investment companies or real estate investment trusts;

•

expatriates or holders who have a “functional currency” other than the U.S. dollar;

•

controlled foreign corporations;

•

passive foreign investment companies; and

•

holders who have, at any point, actually or constructively owned 5% or more of our common stock.

Non U.S. holders of our common stock described in the foregoing sentence and U.S. persons who hold our common stock should consult their own tax advisors as to the tax considerations applicable to the ownership and disposition of our common stock with respect to their particular circumstances.

S-17

TABLE OF CONTENTS

No ruling has been or will be sought from the IRS with respect to any of the U.S. federal income tax considerations discussed below, and no assurance can be given that the IRS will not take a position contrary to the discussion below.

If you are considering the purchase of our common stock, you should consult your own tax advisor concerning the particular U.S. federal income, estate and other tax considerations applicable to you of owning and disposing of our common stock, as well as the considerations applicable to you under the laws of any other applicable taxing jurisdiction (including any state, local or foreign tax laws) in light of your particular circumstances.

Distributions on Common Stock

In general, a distribution, if any, of cash or other property (other than certain distributions of our stock) with respect to our common stock, the distribution will be treated as a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Any portion of a distribution that exceeds our current and accumulated earnings and profits will generally be treated first as a tax free return of capital, on a share by share basis, to the extent of the non U.S. holder’s adjusted tax basis in our common stock, and, to the extent such portion exceeds the non U.S. holder’s adjusted tax basis in our common stock, the excess will be treated as gain from the disposition of the common stock.

The gross amount of dividends paid to a non U.S. holder with respect to our common stock will generally be subject to U.S. federal withholding tax at a rate of 30%, unless (1) an applicable income tax treaty reduces or eliminates such tax, and the non U.S. holder certifies that it is eligible for the benefits of such treaty by timely providing the proper IRS documentation to the applicable withholding agent, or (2) the dividends are effectively connected with the non U.S. holder’s conduct of a trade or business in the United States (and, where required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the non U.S. holder in the United States) and the non U.S. holder satisfies certain certification and disclosure requirements. In the latter case, a non U.S. holder will generally be subject to U.S. federal income tax with respect to such dividends on a net income basis in the same manner as if the non U.S. holder were a U.S. person. Additionally, a non U.S. holder that is a corporation may be subject to an additional “branch profits tax” at a 30% rate (or such lower rate as may be specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year, as adjusted for certain items.

The foregoing discussion is subject to the discussion below under “— Foreign Account Tax Compliance Act.”

Gains on Disposition of Common Stock

In general, a non U.S. holder will not be subject to U.S. federal income tax on gain realized on a disposition of our common stock unless (1) the gain is effectively connected with such non U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the non U.S. holder in the United States), or (2) such non U.S. holder is an individual present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are satisfied.

If the first exception applies, the non U.S. holder will generally be subject to U.S. federal income tax on a net basis and, if it is a foreign corporation, may be subject to a 30% branch profits tax (or lower applicable treaty rate). If the second exception applies, the non U.S. holder will generally be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which capital gains allocable to U.S. sources (including gains from the sale, exchange, redemption or other disposition of our common stock) exceed capital losses allocable to U.S. sources.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury Regulations and administrative guidance promulgated thereunder (commonly referred to as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding at a rate of 30% in certain circumstances on dividends in respect of our common stock which is held by or through certain foreign financial institutions (including investment funds), unless

S-18

TABLE OF CONTENTS

any such institution (1) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (2) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country, or other guidance, may modify these requirements. Accordingly, the entity through which our common stock is held will affect the determination of whether such withholding is required. Similarly, dividends, if any, in respect of our common stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will generally be subject to withholding at a rate of 30%, unless such entity either (1) certifies to us or the applicable withholding agent that such entity does not have any “substantial United States owners” or (2) provides certain information regarding the entity’s “substantial United States owners,” which we or the applicable withholding agent will, in turn, provide to the U.S. Department of the Treasury. We will not pay any additional amounts to investors in respect of any amounts withheld. Prospective investors should consult their tax advisors regarding the possible implications of FATCA on their investment in our common stock.

THIS DISCUSSION OF U.S. FEDERAL INCOME TAX CONSIDERATIONS IS NOT INTENDED TO BE, AND SHOULD NOT BE CONSTRUED AS, TAX ADVICE. THE FOREGOING SUMMARY IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSIDERATIONS APPLICABLE TO YOU OF THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, WHICH ANALYSIS MAY BE COMPLEX AND WILL DEPEND ON YOUR SPECIFIC SITUATION. WE URGE YOU TO CONSULT A TAX ADVISOR REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSIDERATIONS APPLICABLE TO YOU OF THE OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK.

RISK FACTORS

Common Stock

Voting Rights

The holders of our common stock are entitled to one vote per share with respect to all matters required by law to be submitted to stockholders. The holders of our common stock have the sole right to vote. Election of directors requires the affirmative vote of a plurality of shares represented at a meeting, and other general stockholder action (other than an amendment to our certificate of incorporation) requires the affirmative vote of a majority of shares represented at a meeting in which a quorum is represented.

Dividends

The holders of our common stock are titled to receive dividends, if declared by our board, out of funds legally available.

Liquidation

In the event of liquidation, dissolution or winding up of our affairs, the holders of our common stock are titled to share ratably in all assets remaining available for distribution to them after payment or provision for all liabilities.

Rights and Preferences

Our common stock is listed on the NYSE American under the symbol “DC.”

TABLE OF CONTENTS

CERTAIN ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW

Some provisions of Delaware law and our certificate of incorporation and bylaws could make it more difficult for us to be acquired by means of a tender offer, a proxy contest or otherwise or the removal of our incumbent directors and officers. These provisions, summarized below, are expected to discourage and prevent coercive takeover practices and inadequate takeover bids. These provisions are designed to encourage persons seeking to acquire control of our company to first negotiate with our board of directors (the “Board”). They are also intended to provide our management with flexibility to enhance the likelihood of continuity and stability if our Board determines that a takeover is not in the best interests of our stockholders. These provisions, however, could have the effect of discouraging attempts to acquire us, which could deprive our stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Delaware Anti-Takeover Statute

We are subject to Section 203 of the General Corporation Law of the State of Delaware (“DGCL”). Section 203 is an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date that the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a business combination includes a merger, asset or stock sale, or another transaction resulting in a financial benefit to the interested stockholder. Generally, an interested stockholder is a person who, together with affiliates and associates, owns 15% or more of the corporation’s voting stock. The existence of this provision may have an anti-takeover effect with respect to transactions that are not approved in advance by our Board, including discouraging attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

Special Meeting of Stockholders

Our bylaws provide that special meetings of our stockholders may be called only by our Board pursuant to adoption of a resolution.

Election and Removal of Directors

Our certificate of incorporation and bylaws contain provisions that establish specific procedures for appointing members of the Board. In addition, our certificate of incorporation and bylaws provide that, subject to the rights of holders of our preferred stock, vacancies and newly created directorships on the Board may be filled only by a majority of the directors then serving on the Board (except as otherwise required by law or by resolution of the Board).

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. Our bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

No Cumulative Voting

Under Delaware law, cumulative voting for the election of directors is not permitted unless a corporation’s certificate of incorporation authorizes cumulative voting. Our certificate of incorporation and bylaws do not provide for cumulative voting in the election of directors. Cumulative voting allows a minority stockholder to vote a portion or all of its shares for one or more candidates for seats on the board of directors. Without cumulative voting, a minority stockholder will not be able to gain as many seats on our Board based on the number of shares of our stock the stockholder holds as the stockholder would be able to gain if cumulative

TABLE OF CONTENTS

voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our Board to influence our Board’s decision regarding a takeover.

Authorized but Unissued Shares

Our authorized but unissued common stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exclusive Forum Selection

Our certificate of incorporation is silent on forum selection. Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of Delaware shall be the sole and exclusive forum for any stockholder to bring (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the Delaware General Corporation Law or our certificate of incorporation or bylaws or (iv) any other action asserting a claim that is governed by the internal affairs doctrine. If any action within the scope the exclusive forum bylaw provision is filed in a court other than one located within the State of Delaware in the name of a stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce such bylaw provision and (ii) having service of process made upon such stockholder by service upon such stockholder’s counsel in a court other than one located within the State of Delaware as agent for such stockholder. Any person or entity purchasing or otherwise acquiring any interest in our securities shall be deemed to have notice of and consented to this provision. Although we believe these provisions benefit us by providing increased consistency in the application of applicable law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers.

TABLE OF CONTENTS

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our common stock. We may issue warrants independently or together with common stock, and the warrants may be attached to or separate from these securities. We may enter into a warrant agreement with a warrant agent. Each warrant agent may be a bank that we select which has its principal office in the United States. We may also choose to act as our own warrant agent. We will indicate the name and address of any such warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

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

•

the offering price and aggregate number of warrants offered;

•

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;

in the case of warrants to purchase our common stock, the number or amount of shares of common stock purchasable upon the exercise of one warrant and the price at which and currency in which these shares may be purchased upon such exercise;

The description in the prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the warrant agreement and warrant certificate relating to the series of warrants being offered.

Before exercising their warrants, holders of warrants may not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase our common stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

TABLE OF CONTENTS

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. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M., Eastern Time, the close of business, 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 exercise price by the methods 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, if required by the terms of the warrant, issue a new warrant certificate for the remaining amount of warrants.

Enforceability of Rights by Holders of Warrants

Any 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 the holder’s right to exercise, and receive the securities purchasable upon exercise of, its warrants in accordance with their terms.

Warrant Agreement Will Not Be Qualified Under Trust Indenture Act

No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). Therefore, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act with respect to their warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, each warrant agreement and any warrants issued under the warrant agreements will be governed by New York law.

TABLE OF CONTENTS

DESCRIPTION OF UNITS

We may issue units comprised of one or more of the other securities described in this prospectus or any prospectus supplement in any combination. Each unit will be issued so that the holder of the unit is also the holder, with the rights and obligations of a holder, of each security included in the unit. 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 times before a specified date or upon the occurrence of a specified event or occurrence.

The applicable prospectus supplement will describe:

•

the designation and the 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 unit agreement under which the units will be issued;

•

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

•

whether the units will be issued in fully registered or global form.

The description in the prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the unit agreement relating to the series of units being offered.

•

through agents;

•

directly by us to one or more purchasers (including our affiliates and stockholders), through a specific bidding or auction process, a rights offering or otherwise;

The distribution of securities may be effected, from time to time, in one or more transactions, including:

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its own account pursuant to a prospectus supplement or free writing prospectus;

The applicable prospectus supplement or free writing prospectus will describe the terms of the offering of the securities, including:

•

the name or names of any underwriters, if, and if required, any dealers or agents;

•

the purchase price of the securities and the proceeds we will receive from the sale;

Underwriters, Agents and Dealers

We may use one or more underwriters in the sale of the offered securities, in which case the offered securities will be acquired by the underwriter or underwriters for their own account and may be resold from time to time in one or more transactions either:

•

a fixed price or prices, which may be changed;

TABLE OF CONTENTS

•

market prices prevailing at the time of sale;

•

prices related to such prevailing market prices; or

•

negotiated prices.

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in an offering, we will execute an underwriting agreement with such underwriters and will specify the name of each underwriter and the terms of the transaction (including any underwriting discounts and other terms constituting compensation of the underwriters and any dealers) in a prospectus supplement or free writing prospectus. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more investment banking firms or others, as designated. If an underwriting syndicate is used, the managing underwriter(s) will be specified on the cover of the prospectus supplement. If underwriters are used in the sale, the offered securities will be acquired by the underwriters for their own accounts and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. Unless otherwise set forth in the prospectus supplement or free writing prospectus, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent, and the underwriters will be obligated to purchase all of the offered securities, if any are purchased.

We may grant to the underwriters options to purchase additional securities to cover over-allotments, if any, at the public offering price, with additional underwriting commissions or discounts, as may be set forth in a related prospectus supplement or free writing prospectus. The terms of any over-allotment option will be set forth in the prospectus supplement or free writing prospectus for those securities.

If a dealer is used in the sale of the securities, we, or an underwriter, will 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 resale. To the extent required, we will set forth in the prospectus supplement, document incorporated by reference or free writing prospectus, as applicable, the name of the dealer and the terms of the transactions.

We may sell the 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.

We may authorize agents or underwriters to solicit offers by institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement or free writing prospectus pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement or free writing prospectus.

In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities for whom they act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities, and any institutional investors or others that purchase securities directly for the purpose of resale or distribution, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the common stock by them may be deemed to be underwriting discounts and commissions under the Securities Act. No member firm of the Financial Industry Regulatory Authority (“FINRA”) may receive compensation in excess of that allowable under FINRA rules, including Rule 5110, in connection with the offering of the securities.

We may provide agents, underwriters and other purchasers with indemnification against particular civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the

TABLE OF CONTENTS

agents, underwriters or other purchasers may make with respect to such liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

To facilitate the public offering of a series of securities, persons participating in the offering may engage in transactions in accordance with Regulation M under the Exchange Act that stabilize, maintain, or otherwise affect the market price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than have been sold to them by us. In addition, those persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to underwriters or dealers participating in any such offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. 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. Such transactions, if commenced, may be discontinued at any time. We make no representation or prediction as to the direction or magnitude of any effect that the transactions described above, if implemented, may have on the price of our securities.

Unless otherwise specified in the applicable prospectus supplement or free writing prospectus, any common stock sold pursuant to a prospectus supplement will be eligible for trading as listed on the NYSE American. Any underwriters who are qualified market makers to whom securities are sold by us for public offering and sale may make a market in the securities in accordance with Rule 103 of Regulation M, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

In order to comply with the securities laws of some states, if applicable, the securities offered pursuant to this prospectus will be sold in those states only through registered or licensed brokers or dealers. In addition, in some states securities may not be sold 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 complied with.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.
