GAMMA RESOURCES ANNOUNCES AMENDED TERMS FOR ITS U.S. URANIUM PORTFOLIO LEASE AGREEMENT

Gamma Resources Ltd. has successfully renegotiated the payment terms associated with its previously announced lease agreement for its U.S. uranium projects, originally disclosed in a press release dated April 14, 2025. The revised terms provide the company with enhanced financial flexibility while maintaining its rights and interests in the underlying assets.

Amended payment terms

Under the updated agreement, Gamma will satisfy its coming obligations as follows:

• $20,000 (U.S.) payable on or before April 14, 2026 (anniversary payment);
• $50,000 (U.S.) payable on or before May 14, 2026;
• $50,000 (U.S.) payable on or before June 14, 2026;
• $180,000 (U.S.) payable on or before July 14, 2026 (90 days from the anniversary date);
• One million common shares of Gamma, to be issued as soon as practical.

These revised terms replace the previously scheduled lump-sum payment and reflect a mutually agreed restructuring with the counterparty.

The issuance of common shares is subject to the approval of the TSX Venture Exchange. The shares will be subject to a statutory hold period of four months and one day in accordance with applicable securities laws.

The renegotiation aligns Gamma's near-term cash commitments with its broader capital allocation strategy, allowing the company to continue advancing its U.S. uranium portfolio while preserving financial flexibility.

Gamma is currently advancing exploration activities across its U.S. uranium portfolio, including its Mesa Arc project in New Mexico and Green River project in Utah. Continuing work is focused on refining target areas through data compilation and interpretation, permitting, and field-based programs designed to support drill targeting.
