CUSIP No.: 900435108		SCHEDULE 13D		Page 8 of 14 pages

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

As previously reported, on September 5, 2022, Rio Tinto, RTIH and the Company entered into a definitive arrangement agreement (the “Arrangement Agreement”) in respect of a plan of arrangement under the Business Corporations Act (Yukon) (the “YBCA”). The Arrangement Agreement provides for the terms and conditions pursuant to which Rio Tinto has agreed to acquire all of the outstanding share capital in the Company that is not owned directly or indirectly by Rio Tinto and the Company’s minority shareholders (i.e. holders of the approximately 49% of the Company’s share capital that is not owned directly or indirectly by Rio Tinto) (the “Minority Shareholders”) would receive C$43.00 in cash per Share.

The terms of the Arrangement Agreement further provide that the Transaction will be implemented by way of a statutory plan of arrangement under the Business Corporations Act (Yukon) (the “Plan of Arrangement”). The Plan of Arrangement and the implementation of the arrangement set forth therein between the Company, its shareholders, RTIH and Rio Tinto (the “Arrangement”) is subject to the review and approval of the Supreme Court of Yukon. In addition, the Arrangement is subject to certain other conditions, including, among other customary closing conditions, (i) approval of sixty-six and two-thirds percent (66-2/3%) of votes cast by shareholders of the Company (including the Rio Tinto Companies) (the “Company Shareholders”) and (ii) approval of a majority of votes cast by the Minority Shareholders.

The Arrangement Agreement and the Arrangement have been approved by the Boards of Directors of the Company (the “Company Board”) and a special committee of the Company Board comprised solely of independent directors (the “Special Committee”).

As previously reported, on November 1, 2022, in connection with the Arrangement Agreement, RTIH and Rio Tinto entered into agreements (each, a “Withholding Shareholder Agreement”) with certain Minority Shareholders affiliated with Pentwater Capital Management LP and Sailingstone Capital Partners LLC (such Minority Shareholders collectively, the “Withholding Shareholders”), pursuant to which, among other things, each Withholding Shareholder agreed to conduct any dissent proceedings relating to the Arrangement and certain other claims by arbitration in accordance with the terms of the applicable Withholding Shareholder Agreement.

As previously reported, on November 17, 2022, RTIH, Rio Tinto entered into agreements (the “Termination Agreements”) with the Withholding Shareholders, pursuant to which RTIH, Rio Tinto and the Withholding Shareholders have agreed to terminate each of the Withholding Shareholder Agreements. Pursuant to the Termination Agreements, the provisions of the Withholding Shareholder Agreements are terminated and neither RTIH, Rio Tinto nor any of the Withholding Shareholders have any further liability or obligation thereunder. Other than the Termination Agreements, there is no agreement, understanding or commitment between RTIH or Rio Tinto on the one hand and any of the Withholding Shareholders on the other hand, including in any way related to the Arrangement Agreement, any oppression or other claims of the Withholding Shareholders or any of their respective affiliates or any other matter.

As previously reported, on November 17, 2022, Rio Tinto issued a press release (the “Update Press Release”), a copy of which is attached hereto as Exhibit D. As set forth in the Update Press Release, in addition to announcing entry into the Termination Agreements, Rio Tinto also reaffirmed that all Minority Shareholders (including the Withholding Shareholders) have access to the same dissent rights and statutory processes in accordance with the provisions of Section 193 of the YBCA and the interim order, as amended, relating to the Arrangement, as set forth in further details in the Company’s management proxy circular dated September 27, 2022 (the “Circular”), as supplemented by the supplement, dated November 24, 2022, to the Circular (the “Circular Supplement”). The Circular Supplement provides that, among other things, a special meeting of the Company Shareholders to consider and, if advisable, pass a special resolution approving the Arrangement, will be held on December 9, 2022 at 12:00 pm. (Montréal time), as further set forth in the amended interim order attached to the Circular Supplement.

On November 24, 2022, RTIH, Rio Tinto and the Company entered into an amendment to the Arrangement Agreement (the “Arrangement Agreement Amendment”) in order to amend the Plan of Arrangement to give effect to commitments previously described in the Update Press Release (the “Amended Plan of Arrangement”).

Pursuant to the terms of the Arrangement Agreement Amendment, the Amended Plan of Arrangement and the Circular Supplement, as applicable, Rio Tinto agreed to:

•

Waive the 12.5% dissent condition in respect of the Arrangement, provided the Shares for which dissent is validly exercised do not exceed 17.5% of Shares outstanding;

-8-


CUSIP No.: 900435108		SCHEDULE 13D		Page 9 of 14 pages

•

Pay C$34.40 per Share (the “Upfront Payment”) to any Company Shareholder who validly dissents to the Arrangement (a “Dissenting Shareholder”) and elects to receive such amount (an “Electing Shareholder”) not later than December 14, 2022;

•

Pay to an Electing Shareholder interest at the Canada 1 Year Treasury Bill Yield on any balance of “fair value” that becomes payable under the dissent process over and above the Upfront Payment up to C$43.00 in fair value per Share, calculated from the effective date the of the Arrangement, (the “Effective Date”) to the date of any such payment, provided that no other interest shall be payable to an Electing Shareholder in respect of any fair value payment; and

•

Allow any oppression claims by any Minority Shareholders, including Electing Shareholders, against the Company, Rio Tinto or their respective affiliates to survive the Arrangement and be pursued following the Effective Date, where such claims are served on or provided to the Company and Rio Tinto no later than seven days following the Effective Date.

The foregoing descriptions of the Arrangement Agreement Amendment, Circular Supplement, Termination Agreements, the Update Press Release, the Withholding Shareholder Agreements and the Arrangement Agreement do not purport to be complete and they are qualified in their entirety by reference to Exhibit A, B, C, D, E, F, G and J respectively, which are incorporated herein by reference.

Other than as described in the Schedule 13D, none of the Reporting Persons has any plans or proposals of the type referred to in clauses (a) through (j) of Item 4 of Schedule 13D, although they and their affiliates reserve the right to formulate such plans or proposals in the future. If the Arrangement is not consummated, the Rio Tinto Companies and their affiliates will continue to regularly review and assess their investment in the Company and depending on market conditions and other factors may determine, from time to time, to engage in any of the events set forth in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

Rio Tinto beneficially owns 102,196,643 Shares, representing 50.8 percent of the outstanding Shares. Such Shares are held by Rio Tinto indirectly through RTIH (as to 43,947,833 Shares, representing 21.8 percent of the outstanding Shares, which are also beneficially owned by RTIH), indirectly through 7999674 Canada Inc. (as to 21,510,000 Shares, representing 10.7 percent of the outstanding Shares, which are also beneficially owned by 7999674 Canada Inc.), indirectly through 46117 Yukon Inc.

(as to 21,510,000 Shares, representing 10.7 percent of the outstanding Shares, which are also beneficially owned by 535630 Yukon Inc.).

Rio Tinto has anti-dilution rights that permit it to acquire additional securities of the Company so as to maintain its proportional equity interest in the Company.

Rio Tinto also has the right, subject to the terms and conditions of its financing support agreement with the Company, to require that the Company effect an equity contribution by way of private placement of Shares to Rio Tinto or a rights offering in the event a fact or circumstance occurs which (i) affects or could reasonably be expected to affect the Company’s ability to meet its obligations under the sponsor debt service undertaking that the Company entered into with Rio Tinto, the project lenders and agents representing such lenders or (ii) gives rise to an event of default or completion default under the agreements entered into in connection with the OT project finance facility.

The percentages of Shares reflected above and in the responses in Row (13) of the cover pages of this Schedule 13D with respect to each of the Rio Tinto Companies are based on 201,231,446 outstanding Shares as of September 30, 2022, as disclosed by the Company in its Management’s Discussion and Analysis of Financial Condition and Results of Operation for the period ended September 30, 2022 attached as an Exhibit to the Company’s Report on Form 6-K filed with the SEC on November 14, 2022.

In addition, with respect to each of the Rio Tinto Companies, each of the Rio Tinto Companies shares voting power and dispositive power with respect to the Shares beneficially owned by such person.
