On August 13, 2025, Rigel Resource Acquisition Corp (the "Company") entered into a Promissory Note (the "Extension Loan") with its sponsor, Rigel Resource Acquisition Holding LLC (the "Sponsor") and Orion Mine Finance GP III LP ("Orion").

Pursuant to the Extension Loan, the Sponsor and Orion have agreed that they will contribute to the Company as a loan (each loan being referred to herein as a "Contribution") in an amount equal to the lesser of (x) $55,000 and (y) $0.02 for each Public Share (as defined below) that was not redeemed in connection with the Special Meeting (as defined below), for each month (or a pro rata portion thereof if less than a month) until the earlier of (i) the date of the closing of the Business Combination and (ii) November 9, 2025. The Contributions will be deposited into the Company's Trust Account.

The maturity date of the Extension Loan may be accelerated upon the occurrence of an Event of Default (as defined therein). Any outstanding principal under the Extension Loan may be prepaid at any time by the Company, at its election and without penalty.

The foregoing description of the Extension Loan does not purport to be complete and is qualified in its entirety by the terms and conditions of the Extension Loan, a copy of which is attached hereto as Exhibits 10.1 and incorporated herein by reference.

On August 8, 2025, the Company held a special meeting (the "Special Meeting") at which holders of 11,017,557 of the Company's ordinary shares, comprised of 3,565,057 Class A Ordinary Shares and 7,452,500 Class B ordinary shares, par value $0.0001 per share ("Class B Ordinary Shares"), were present in person or by proxy, representing approximately 75.3% of the voting power of the 14,629,558 then-issued and outstanding ordinary shares of the Company, comprised of 7,129,558 Class A Ordinary Shares and 7,500,000 Class B Ordinary Shares, entitled to vote at the Special Meeting at the close of business on January 10, 2025, which was the record date (the "Record Date") for the Special Meeting. Shareholders of record as of the Record Date are referred to herein as "Shareholders". In connection with the Extension Amendment (as defined below), the holders of 1,114,441 Class A Ordinary Shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $12.07 per share, for an aggregate redemption amount of approximately $13,449,620, leaving approximately $18,415,659 in the Company's trust account. A summary of the voting results at the Special Meeting for each of the proposals is set forth below.

<u>Proposal 1</u>

The Shareholders approved the proposal to amend the Company's Amended and Restated Memorandum and Articles of Association (the "Charter") to extend the date by which the Company must either (1) consummate a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Company with one or more businesses or entities (a "**Business Combination**") or (2) (i) cease its operations, except for the purpose of winding up if it fails to complete an initial Business Combination, and (ii) redeem all of the Class A ordinary shares, par value $0.0001 per share, of the Company, included as part of the units sold in the Company's initial public offering, which was consummated on November 9, 2021, from August 9, 2025 to November 9, 2025, or such earlier date as determined by the Company's board of directors (the "**Extension**," and such proposal, the "**Extension Proposal**"). The voting results for the Extension Proposal were as follows:

---

| | | |
|:---|:---|:---|
| **Votes For** | **Votes Against** | **Votes Abstaining** |
| 10851571 | 165986 | 0 |

---

<u>Proposal 2</u>

The proposal to adjourn the Special Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there were insufficient votes for, or otherwise in connection with, the approval of the Extension Proposal was not presented at the Special Meeting since the Extension Proposal each received a sufficient number of votes for approval.

**13. Amendment; Waiver.** Any amendment hereto or waiver of any provision hereof may be made with, and only with, the written consent of Maker and Payees.

**14. Successors and Assigns**. Subject to the restrictions on transfer in Sections 15 and 16 below, the rights and obligations of Maker and Payees hereunder shall be binding upon and benefit the successors, assigns, heirs, administrators and transferees of any party hereto (by operation of law or otherwise) with the prior written consent of the other party hereto and any attempted assignment without the required consent shall be void.

**15. Transfer of this Note**. With respect to any sale or other disposition of this Note, Payees shall give written notice to Maker prior thereto, describing briefly the manner thereof, together with (i) except for a Permitted Transfer (as defined below), in which case the requirements in this clause (i) shall not apply, a written opinion (unless waived by Maker) reasonably satisfactory to Maker in form and substance from counsel reasonably satisfactory to Maker to the effect that such sale or other distribution may be effected without registration or qualification under any federal or state law then in effect and (ii) a written undertaking executed by the desired transferee reasonably satisfactory to Maker in form and substance agreeing to be bound by the restrictions on transfer contained herein. Upon receiving such written notice, reasonably satisfactory opinion (unless waived by Maker), or other evidence, and such written acknowledgement, Maker, as promptly as practicable, shall notify Payees that Payees may sell or otherwise dispose of this Note, all in accordance with the terms of the note delivered to Maker. If a determination has been made pursuant to this Section 15 that the opinion of counsel for Payees, or other evidence, or the written acknowledgment from the desired transferee, is not reasonably satisfactory to Maker, Maker shall so notify Payees promptly after such determination has been made. Each Note thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with the Securities Act of 1933, as amended (the "**Securities Act**"), unless in the opinion of counsel for Maker such legend is not required in order to ensure compliance with the Securities Act. Maker may issue stop transfer instructions to its transfer agent in connection with such restrictions. Subject to the foregoing, transfers of this Note shall be registered upon registration on the books maintained for such purpose by or on behalf of Maker. Prior to presentation of this Note for registration of transfer, Maker shall treat the registered holder hereof as the owner and holder of this Note for the purpose of receiving all payments of principal hereon and for all other purposes whatsoever, whether or not this Note shall be overdue and Maker shall not be affected by notice to the contrary. For purposes hereof "**Permitted Transfer**" shall have the same meaning as any transfer that would be permitted for the Private Placement Warrants under the Letter Agreement, dated November 4, 2021, among Maker, Payees and the other parties thereto.

**16. Acknowledgment.** Payees are acquiring this Note for investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any distribution thereof in violation of applicable securities laws. Payees understand that the acquisition of this Note involves substantial risk.
