UPDATE ON EXPECTED CLOSING OF STAR DIAMOND’S ACQUISITION OF

RIO TINTO’S 75% INTEREST IN THE FORT À LA CORNE DIAMOND PROJECT

SASKATOON, Saskatchewan, January 29, 2024 – Star Diamond Corporation (TSX: DIAM) (“Star Diamond”

or the “Company”) is pleased to provide this update on Star Diamond’s acquisition of Rio Tinto Canada

Inc’s (“RTEC”) 75% interest in the Fort à la Corne Joint Venture pursuant to the agreement (the

“Agreement”) dated November 28, 2023 entered into between Star Diamond and RTEC (see News Release

dated November 28, 2023).

Star Diamond and RTEC have worked together diligently to submit the documentation required to

complete the transfer of the P ermit to O perate for the Fort à la Corne properties (“the Project”) . This

process requires that an updated Decommissioning and Reclamation Plan be submitted to the

Saskatchewan Ministry of the Environment (the “MoE“) for its approval.

Star Diamond and RTEC have been in active discussions with the MoE and, based upon those discussions,

Star Diamond believes that all documents required by the MoE have been submitted for its review. Based

upon discussions with the MoE, Star Diamond currently expects that the transfer of the Permit to Operate

will be completed prior to the end of March 2024.

Star Diamond CEO Ewan Mason said: “We are pleased that the MoE has committed to move the review

process forward expeditiously. While we anticipate that Star Diamond will take full possession of the

Project in March, we are not waiting for this transfer to be completed to execute upon our plan and are

well underway with the revised Mineral Resource and Pre-feasibility Study previously announced. Our

staff is also busy examining the requirements for site security, monitoring and maintenance so that the

handover from RTEC to Star Diamond proceeds seamlessly”.

Completion of the transactions contemplated by the Agreement is subject to various closing conditions

including receipt of all required Governmental approvals and the approval of the Toronto Stock Exchange

for the issuance of additional common shares of Star Diamond to RTEC.
