KIRKSTONE METALS UPDATES GORILLA LAKE AND KEY LAKE ROAD PERMITTING AND TERMINATES SAMSON METALS ACQUISITION

Kirkstone Metals Corp. has updated shareholders on its continuing permitting at the company's Key Lake Road and Gorilla Lake Athabasca uranium projects.

Kirkstone is permitting up to 6.2 kilometres of line cutting for induced polarization along with up to 30 drill holes targeting the DD zone at Key Lake Road. The DD zone lies on a north-south-trending fault, consistent with the Wollaston-Mudjatik transition zone, the primary geological feature controlling the uranium mineralization at the historic and producing uranium mines on the eastern side of the Athabasca basin. Historic prospecting and multiple drilling campaigns at the DD zone have consistently identified highly anomalous uranium mineralization. The IP survey is expected to assist in defining and sharpening drill targets for the coming program. Kirkstone is currently in the process of consulting with local first nations and interested stakeholders in the Key Lake Road area as an integral part of the permitting process.

Gorilla Lake is permitting up to 7,000 metres of diamond drilling to follow up on a coming airborne time domain electromagnetic survey and subsequent ground truthing. Historic exploration concentrated on the western portion of the claim group, where anomalous uranium mineralization was intersected, leaving the bulk of the property significantly underexplored. A 2024 company heli-TEM survey identified several potential structural trends worthy of follow-up. Kirkstone is currently in the process of consulting with local first nations and interested stakeholders in the Gorilla Lake area as an integral part of the permitting process.

The company will provide further updates as the permitting process advances and as exploration plans are refined.

Further to the company's news release dated April 23, 2026, the company has decided not to proceed with the acquisition of all of the issued and outstanding shares of Samson Metals Corp. pursuant to the share purchase agreement dated April 22, 2026.
