TRISTAR GOLD ANNOUNCES UPSIZE OF PRIVATE PLACEMENT OFFERING TO C$9 MILLION

Tristar Gold Inc. has amended its engagement with Stifel Canada, as lead agent and sole bookrunner, in connection with a best-efforts private placement that has been increased to 39.14 million units of the company at a price of 23 cents per unit for aggregate gross proceeds of $9,002,200.

Each unit will consist of one common share and one-half of one common share purchase warrant of the company. Each warrant will be exercisable to acquire one additional common share for a period of 24 months following the closing date of the offering at an exercise price of 30 cents per warrant share.

The company will grant to the agents an option to sell up to such number of additional units that is equal to 15 per cent of the units sold under the offering at the offering price. The agents' option will be exercisable in whole or in part, at the sole discretion of the agents, up to 48 hours prior to the closing date.

The net proceeds from the offering are expected to be used for exploration and development of the company's mineral properties, as well as for general working capital.

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106, Prospectus Exemptions, the units will be offered for sale to purchasers resident in Canada other than Quebec and/or other qualifying jurisdictions pursuant to the listed issuer financing exemption under Part 5A of NI 45-106. Because the offering is being completed pursuant to the listed issuer financing exemption, the units issued pursuant to the offering will not be subject to a hold period pursuant to applicable Canadian securities laws. There is an offering document related to the offering that can be accessed under the company's issuer profile on SEDAR+ and on the company's website. Prospective investors should read the offering document before making an investment decision.

The agents will be paid by the company on the closing date a cash commission equal to 6 per cent of the gross proceeds of the offering, including on any exercise of the agents' option. The agents will also receive compensation warrants equal to 6 per cent of the number of units sold pursuant to the offering on the closing date. Each compensation warrant will entitle the holder thereof to subscribe for one common share at the offering price for a period of 24 months following the closing date.

The offering is scheduled to close on or about June 4, 2026, and is subject to certain conditions, including, but not limited to, the receipt of all necessary regulatory and other approvals, including the approval of the TSX Venture Exchange.
