KIRKSTONE METALS FILES IP AND DRILLING PERMIT FOR KEY LAKE ROAD PROJECT

Kirkstone Metals Corp. has filed a permit for 2026 exploration at the Key Lake road uranium project, located in Northern Saskatchewan, south of the Key Lake mine. The company is permitting 6.2 kilometres of line cutting for the induced polarization survey at the DD zone, announced Nov. 25, 2025, along with 30 drill pads for a subsequent drill program at the DD zone and the Highway zone.

The company continues to review, compile and interpret the historic exploration data on this project with the goal of derisking the DD and Highway zone targets to the maximum extent prior to drilling.

Clive Massey, president and chief executive officer, commented: "Our permit submissions for drilling at our Key Lake project in the Athabasca basin reflect both our confidence in the project's potential and our commitment to responsible, community-focused exploration. This is an important milestone as we work to support the future of clean, reliable nuclear energy."

The DD zone was first identified by Forum Uranium in the mid-2000s and is characterized by a north-south-trending fault, consistent with the Wollaston-Mudjatik transition zone (WMTZ), the primary geological feature controlling the uranium mineralization at the historic and producing uranium mines on the eastern side of the Athabasca basin.

Previous prospecting and multiple drilling campaigns at the DD zone have consistently identified highly anomalous uranium mineralization. Highlights include:

• DD-01 with values to 1,250 parts per million uranium over 0.25 metre at 157.75 m to 158 m depth;
• DD-15 with anomalous highlights values of 155 ppm nickel, 664 ppm copper and 159 ppm lead;
• DD-03, DD-16, DD-19 and DD-21, drilled near a rock sample with 6,150 ppm uranium, recorded highlight uranium values of 761 ppm and copper, nickel, cobalt and lead values in the range of 200 to 300 ppm;
• DD-07 with uranium values between 117 and 227 ppm over short intervals (0.2 m);
• KLR23-05 and KLR23-06, which encountered a fault zone with massive pyrrhotite-pyrite and uranium values between 200 and 300 ppm; gamma probe results in these holes included 5,800 counts per second, 8,000 cps and 10,300 cps;
• Backpack drill hole KLR 15-37 with a uranium high of 1.57 per cent over four centimetres; six core samples over 1,000 ppm were drilled in the area of interest during the 2015 program.

The KLR project, located approximately 90 kilometres south of Cameco's Key Lake mine and mill, lies within the Wollaston-Mudjatik transition zone (WMTZ) -- a prolific structural corridor hosting several of the world's highest-grade uranium deposits, including Key Lake, Cigar Lake and McArthur River.
