Company Announcements

VANCOUVER, BC , June 16, 2025 /PRNewswire/ -Lumina Gold Corp.(TSXV: LUM) (OTCQB: LMGDF) (the "Company" or "Lumina") is pleased to announce that, the holders ("Shareholders") of common shares of the Company ("Shares"), holders of options of the Company ("Optionholders") and holders of restricted share units of the Company (the "RSU Holders" and together with the Shareholders and Optionholders, the "Securityholders") have voted in favour of the previously announced acquisition of the Company with CMOC Singapore Pte. Ltd., a Singapore entity and a subsidiary of CMOC Group Limited (collectively "CMOC") pursuant to a plan of arrangement under the Business Corporations Act (British Columbia) (the "Arrangement") at the Company's special meeting of Securityholders (the "Meeting") held earlier today.

The completion of the Arrangement required the approval of: (i) at least two thirds (66 2/3%) of the votes cast by Shareholders present in person or by proxy and entitled to vote at the Meeting; (ii) at least two thirds (66 2/3%) of the votes cast by the Securityholders, voting as a single class, present in person or represented by proxy and entitled to vote at the Meeting; and (iii) a simple majority of the votes cast at the Meeting by Shareholders in person or represented by proxy and entitled to vote at the Meeting, excluding votes cast in respect of Shares beneficially owned or over which control or direction is exercised by any persons whose votes must be excluded in accordance with Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101").

The matter voted upon at the Meeting and the results of the voting were as follows:

Subject to receipt of a final order in respect of the Arrangement from the Supreme Court of British Columbia (the "Court"), and satisfaction or waiver of the other conditions to closing contained in the arrangement agreement entered into among the Company, CMOC, and Acquireco dated April 21, 2025 (the "Arrangement Agreement"), the Arrangement is expected to close in late June.

Further to the Company's disclosure in the Circular, the Company determined that Martin Rip, Chief Financial Officer and a related party (as defined in MI 61-101) of Lumina, beneficially owns or exercises control or direction over greater than one percent (1%) of the total Shares. The special committee of independent members of the board of directors of Lumina did not determine that the value of the benefit, net of any offsetting costs to Mr. Rip, was less than 5% of the value of the consideration Mr. Rip expected he would be beneficially entitled to receive under the Arrangement in exchange for the securities of the Company he beneficially owned. As a result, Mr. Rip's votes in respect of the Shares he beneficially owned or over which he exercised control or direction were excluded from the vote for minority shareholder approval sought pursuant to MI 61-101 at the Meeting.

Further details regarding the Arrangement are provided in the Circular which is available on SEDAR+ at www.sedarplus.ca under the Company's issuer profile.
