Trillium Gold Mines Inc. Completes Plan of Arrangement to Acquire Pacton Gold Inc.

The Arrangement was approved at a special meeting of shareholders of Pacton held on June 2, 2023 followed by the issuance of the final order approving the Arrangement from the Supreme Court of British Columbia on June 6, 2023.

Pursuant to the Arrangement, each former holder of Pacton common shares (each, a "Pacton Share") is entitled to receive 1.275 common shares of Trillium (each such whole common share, a "Trillium Share") in exchange for each Pacton Share held. Upon completion of the Arrangement, existing Trillium and Pacton shareholders will own 53% and 47%, respectively, of the combined company.

In addition, all outstanding stock options of Pacton were exchanged for stock options to acquire up to an aggregate of 2,198,737 Trillium Shares. All outstanding warrants of Pacton remain in effect, but are now exercisable to acquire 42,075 Trillium Shares. Prior to the completion of the Arrangement, Trillium did not own any Pacton securities.

Further details of the Arrangement are set out in Pacton's management information circular dated May 2, 2023 (the "Circular"). Registered Pacton shareholders should send their completed and executed letters of transmittal and certificates representing their Pacton Shares to the depositary for the Arrangement, Computershare Investor Services Inc., in accordance with the instructions contained in the letter of transmittal as soon as possible in order to receive the Trillium Shares to which they are entitled pursuant to the Arrangement. A copy of the Circular and the letter of transmittal can be found under Pacton's profile on SEDAR at www.sedar.com.
