Item 4. | Purpose of Transaction |
The Reporting Persons originally acquired the securities reported herein for investment purposes in the ordinary course of business and not with the purpose, nor with the effect, of changing or influencing the control or management of the Issuer. The Reporting Persons have engaged in, and intend to continue to engage in, communications with the Issuer's management and board of directors, other current and prospective holders of the Issuer's equity and debt securities, and other third parties about, and intend to negotiate agreements with the Issuer regarding, a broad range of consensual transactions intended to deleverage and recapitalize the Issuer to support the Issuer's continued operations and development of its cobalt sulfate refinery. Any such transactions may involve, among other things, changes in the Issuer's capital structure, corporate governance, constituent documents and board composition, the exchange of some or all of the securities and royalty rights reported herein for newly issued equity or debt securities of the Issuer and its subsidiaries, and the acquisition of newly issued equity or debt securities of the Issuer and its subsidiaries for cash. Any such transactions may result in the Reporting Persons and the Named Holders (as defined below) requesting or obtaining representation on the Issuer's board of directors, acquiring control of a majority of the Issuer's outstanding equity securities, or any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D. With respect to the foregoing, the Reporting Persons have initiated discussion with the holders of the issuer's debt securities named in Item 5 hereto (the "Named Holders"). The Reporting Persons, together with the Named Holders, may engage with the Issuer on the matters set forth in the preceding paragraph, and may in the future take actions concerning their respective investments in the Issuer with respect thereto. There can be no guarantee that the Reporting Persons will make any proposal regarding any of the matters set forth in the preceding paragraph, either on their own or in conjunction with some or all of the Named Holders, and if any such proposal is made, the Reporting Persons can provide no assurances such proposal will be accepted or that it will successfully consummate any proposed transaction. To facilitate its consideration of such matters, the Reporting Persons, together with the Named Holders, have retained, or intend to retain, consultants, legal counsel and advisors. The Reporting Persons may also, from time to time, engage in discussions with members of the Issuer's management and board of directors, other current and prospective holders of the Issuers' equity and debt securities, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, equity and debt financing sources and other third parties regarding a variety of matters relating to the Issuer, which (in addition to the matters discussed above) may include, among other things, the Issuer's business, management, capital structure, capital allocation, corporate governance, board composition and strategic alternatives and direction, and may take other steps seeking to bring about changes to increase shareholder value as well as pursue other plans or proposals that relate to or could result in any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors, including, without limitation, the outcome of any discussions and negotiations referenced above, the Issuer's financial position and investment strategy, results and strategic direction, actions taken by the Issuer's management and board of directors, price levels of the Issuer's securities, other investment opportunities available to the Reporting Persons, conditions in the securities market, and general economic and industry conditions, the Reporting Persons intend to consider, explore, and develop plans and may in the future take such actions with respect to their investment in the Issuer as they deem appropriate, including, without limitation, engaging in communications with the Issuer's management and board of directors, engaging in discussions with holders of the Issuer's equity and debt securities and others about the Issuer and the Reporting Persons' investment, making proposals to the Issuer concerning changes to the capital allocation strategy, capitalization, ownership structure, strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, board composition and structure, operations of the Issuer, purchasing additional securities of the Issuer, selling some or all of their securities of the Issuer, engaging in short selling of or any hedging or similar transaction with respect to the securities of the Issuer, or take any other actions with respect to their investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons may at any time reconsider and change their plans or proposals relating to the foregoing. | |
Item 5. | Interest in Securities of the Issuer |
(a) | The information set forth in Item 6 is incorporated herein by reference. Each of the Reporting Persons is deemed to be the beneficial owner of 1,941,016 Common Shares, as a result of Whitebox Funds' ownership of: (i) 296,965 Common Shares; (ii) warrants to purchase 1,349,507 Common Shares at an exercise price of CAD$3.40 per Common Share ("February Warrants"); (iii) warrants to purchase 727,273 Common Shares at an exercise price of CAD$4.00 per Common Share ("November Warrants" and, together with February Warrants, "Warrants"); (iv) $29,333,000 principal amount of 8.99% Convertible Senior Secured Notes due 2028 with the conversion rate of 100.8035 Common Shares per $1,000 principal amount ("2028 Notes"), which are convertible into 2,956,869 Common Shares; and (v) $2,566,000 principal amount of 12.00% Convertible Senior Secured Notes due 2027 with the conversion rate of 400.3523 Common Shares per $1,000 principal amount ("2027 Notes" and, together with 2028 Notes, "Notes"), which are convertible into 1,027,304 Common Shares, with each of (ii) through (v) subject to the 9.9% Blocker (defined below). Each of the Reporting Persons is deemed to beneficially own 9.9% of Common Shares outstanding. Percent of class is calculated based on (i) 17,962,173 Common Shares outstanding as of June 25, 2025, as disclosed on the Issuer's registration statement on Form F-3 filed with the SEC on June 27, 2025, plus (ii) an aggregate 1,644,051 Common Shares obtainable upon the exercise of the Warrants and the conversion of the Notes beneficially owned by the Reporting Person, which Common Shares have been added to the total Comm
on Shares outstanding pursuant to Rule 13d-3(d)(1)(i) under the Act. Pursuant to the terms of the Warrants and Notes, the Reporting Persons cannot exercise or convert any of the Warrants or Notes if the Reporting Persons (or any "group" of which the Reporting Persons are members) would beneficially own, after any such exercise or conversion, as applicable, more than 9.9% of the outstanding Common Shares (the "9.9% Blocker"). Consequently, at this time, the Reporting Persons are not able to exercise and convert all of the Warrants and Notes due to the 9.9% Blocker. The percentages set forth in Row (13) of the cover page and in the footnote set forth on the cover page for the Reporting Persons give effect to the 9.9% Blocker. As a result of the Reporting Persons' involvement in the discussions and potential actions described in Item 4 of this Schedule 13D, the Reporting Persons and the Named Holders may be deemed to be member of a "group" for the purposes of Section 13(d)(3) of the Act, which may consist of the Reporting Persons and Highbridge Capital Management, LLC and O'Connor, a distinct business unit of UBS Asset Management (Americas) LLC. The "group" may be deemed to have acquired beneficial ownership of all the shares beneficially owned by each member of the "group," subject to the 9.9% Blocker. As such, the "group" may be deemed to beneficially own in the aggregate 1,925,360 Common Shares or 9.9% of the outstanding Common Shares, as calculated pursuant to Rule 13d-3(d)(1)(i) under the Act. On information and belief, the Reporting Persons understand that the Named Holders are filing Schedule 13D separately from the Reporting Persons. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by the Reporting Persons that they are a group with the Named Holders or the beneficial owner of any of the Common Shares beneficially owned by any Named Holder for purposes of Section 13(d) of the Act or for any other purpose, and such beneficial ownership is expressly disclaimed. |
(b) | The information contained in rows 7, 8, 9 and 10 on the cover page of this Schedule 13D is incorporated herein by reference in its entirety. |
(c) | The Reporting Persons have not effected transactions in the Common Shares during the past sixty days. |
(d) | The Whitebox Funds are known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Common Shares beneficially owned by the Reporting Persons. None of the Whitebox Funds individually has such right with respect to more than 5% of the Common Shares outstanding. |
(e) | Not applicable. |
Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer |
The information set forth in Items 2 and 4 is incorporated herein by reference. The Reporting Persons currently own the following securities: (i) 296,965 Common Shares; (ii) $29,333,000 principal amount of the 2028 Notes issued under that certain Indenture, dated as of February 13, 2023, by and between, the Issuer, the Guarantors Party thereto, and GLAS Trust Company LLC, as Trustee and Collateral Trustee, attached as Exhibit 99.1 to the Report of Foreign Private Issuer on Form 6-K filed with the SEC on February 14, 2023, which has been supplemented by that certain Supplemental Indenture, dated as of November 27, 2024, by and between, the Issuer, the Guarantors Party thereto, and GLAS Trust Company LLC, as Trustee and Collateral Trustee, attached as in Exhibit 99.2 to the Report of Foreign Private Issuer on Amended Form 6-K/A filed with the SEC on November 27, 2024; (iii) $2,566,000 principal amount of the 2027 Notes issued under that certain Indenture, dated as of November 27, 2024, by and among the Issuer, the Guarantors Party thereto, and GLAS Trust Company, LLC, as Trustee and Collateral Trustee, attached as Exhibit 99.1 to the Report of Foreign Private Issuer on Amended Form 6-K/A filed with the SEC on November 27, 2024; (iv) November Warrants to purchase 727,273 Common Shares issued pursuant to that certain Warrant Indenture, dated as of November 27, 2024, by and between the Issuer and TSX Trust Company, attached as Exhibit 2.11 to the Annual Report on Form 20-F for the fiscal year ended December 31, 2024 filed with the SEC on April 24, 2025; and (v) February Warrants to purchase 1,349,507 Common Shares issued pursuant to that certain Warrant Indenture, dated as of February 13, 2023, by and between the Issuer and TSX Trust Company, attached as Exhibit 99.2 to the Report of Foreign Private Issuer on Form 6-K filed with the SEC on February 14, 2023, which has been supplemented by (x) that certain First Supplemental Indenture, dated as of January 12, 2024, by and between the Issuer and TSX Trust Company attached as Exhibit 2.4 to the Issuer's Annual Report on Form 20-F for the fiscal year ended December 31, 2024 filed with the SEC on April 24, 2025 and (y) that certain Second Supplemental Indenture, dated as of November 27, 2024, by and between the Issuer and TSX Trust Company attached as Exhibit 2.5 to the Issuer's Annual Report on Form 20-F for the fiscal year ended December 31, 2024 filed with the SEC on April 24, 2025. As further described in Exhibit 99.2 attached to the Issuer's Report of Foreign Private Issuer on Form 6-K filed with the SEC on March 6, 2025, the Whitebox Funds entered into an agreement with the Issuer and agreed to defer all interest payments with respect to the Notes until February 15, 2027. As consideration for this deferral, the Issuer will pay additional interest of 2.25% per annum on the 2028 Notes and 2.5% per annum on the 2027 Notes, calculated on the principal amounts of the Notes. All deferred interest, including deferred amounts of additional interest, will accrue interest at the applicable stated rate of interest borne by the applicable series of Notes. All deferred interest (including all interest thereon) will become payable immediately if an event of default occurs under the applicable note indenture prior to February 15, 2027.

For the Whitebox Funds, royalty payments under the royalty agreements are subject to a cumulative cap of $3,000,000.
