November 24 th , 2025 – Vancouver, BC, Canada – TheNewswire - Kirkstone Metals Corp. (the “ Company ” or “ Kirkstone ”) (TSXV: KSM, FWB:VO0) is pleased to announce phase I exploration plans for the Key Lake Road Uranium Project, located in northern Saskatchewan, south of the Key Lake Mine. The company has devised a multiphase exploration strategy to leverage the wealth of historic exploration data on this project. The first phase calls for an induced polarization (IP) survey in the northern extent of the project area, where the DD Zone is located. The DD Zone, first identified by Forum Uranium, is characterized by a north-south trending fault, which is 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 east side of the Athabasca Basin.

Previous prospecting and multiple drilling campaigns at the DD Zone has consistently identified highly anomalous uranium mineralization. The IP survey, which will consist of up to 12 line kilometers, will be used to accurately define prospective subsurface anomalies as well as the geological structural controls. Data from this survey will be used in defining potential diamond drilling targets in subsequent programs.

DD Zone Highlights:

• DD-01 with values to 1250ppm uranium over 0.25m at 157.75m-158m depth 1

• DD-15 with anomalous highlights values of 155 ppm nickel, 664 ppm copper and 159 ppm lead 1

• DD-03, 16, 19, and 21 drilled near a rock sample with 6150ppm uranium, recorded highlight uranium values of 761 and copper, nickel, cobalt and lead values in the 200 to 300 ppm range 1

• DD-07 with uranium values between 117 and 227 ppm over short intervals (0.2m) 1

• 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 ("CPS"), 8,000 CPS and 10,300 CPS. 3

• Backpack drill hole KLR 15-37 with a uranium high of 1.57% over 4cm. 6 core samples over 1,000 ppm were drilled in the area of interest during the 2015 program. 2

Clive Massey, President and CEO , commented:

“Since finalizing the option agreement our technical team has been focused on developing a disciplined, data-driven exploration program aimed at unlocking the property’s full potential. We believe at this stage an induced polarization survey is the best method to further advance the project toward the eventual goal of drilling. We are anxious to  drill this project as we feel this will demonstrate the projects technical superiority leading to a potential discovery”

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.
