CUSIP No.: 95805V108		SCHEDULE 13D		Page 4 of 8 pages

Item 1. Security and Issuer

This Amendment No. 1 (“Amendment No. 1”) relates to the Statement on Schedule 13D (this “Schedule 13D”) filed on November 23, 2022 by Rio Tinto plc, a public limited company incorporated under the laws of England and Wales (“Rio Tinto”), and Rio Tinto Canada Inc., a corporation incorporated under the laws of Canada (“RTCI” and, together with Rio Tinto, the “Rio Tinto Companies”). Except as otherwise provided herein, each item of the Original Schedule 13D remains unchanged.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 of the Original Schedule 13D is hereby amended and supplemented by adding the following information:

On November 27, 2023, RTCI and the Company entered into a Subscription Agreement (the “Subscription Agreement”) pursuant to which, among other things and subject to the terms and conditions thereof, the Company agreed to issue to RTCI in a private placement, and RTCI agreed to purchase from the Company, 3,468,208 Shares at a subscription price of C$1.73 per Share. The aggregate subscription price (the “Subscription Amount”) for the Shares to be issued to RTCI is C$5,999,999.84. RTCI expects to obtain the funds for the Subscription Amount from working capital to be provided by Rio Tinto. A copy of the Subscription Agreement is filed with this Schedule 13D/A as Exhibit E and is incorporated herein by reference.

Item 4. Purpose of Transaction

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following information:

The information set forth in Item 3 of this Schedule 13D/A is incorporated by reference in its entirety into this Item 4.

In connection with the Subscription Agreement, RTCI and the Company agreed that, at the closing of the acquisition of Shares under the Subscription Agreement, they would enter into an Amended and Restated Investor Rights Agreement (the “A&R Investor Rights Agreement”). A copy of the form of A&R Investor Rights Agreement is filed with this Schedule 13D as Exhibit F and is incorporated herein by reference. Under the A&R Investor Rights Agreement, RTCI would retain its right (but not the obligation) to acquire additional securities in the Company so as to maintain its proportional equity interest in the Company.

The A&R Investor Rights Agreement also extends for 18 months from the closing of the acquisition of Shares under the Subscription Agreement (the “Extended Investor Rights Period”), RTCI’s rights to: (a) appoint a non-voting observer to the Company’s board of directors, (b) appoint a member to the Company’s technical and sustainability committee, (c) appoint member to the board of directors of the Company if RTCI’s ownership in the Company were to increase to more than 12.5%; (d) participate in a secondment program with the Company; (e) receive quarterly reports and access the Company’s books and records; and (f) receive draft press releases describing study results.

Under the A&R Investor Rights Agreement, RTCI will also be entitled to customary registration rights to facilitate a public offering or distribution of Shares if it were to choose to sell its Shares, and RTCI will also be subject to customary standstill arrangements, as set out in the A&R Investor Rights Agreement, during the Extended Investor Rights Period.
