Full Description of Material Change

Vancouver, British Columbia, November 3, 2022 – Atco Mining Inc. (the “Company” or “Atco”) (CSE: ATCM) is pleased to announce an update on its two salt mining projects located on the west coast of Newfoundland.

Atco’s first salt project, the Lunar North Salt Project, consists of 16 claims, totalling 400 hectares, strategically located on the western boundary of the Atlas Salt Inc. (TSX-V: SALT) property which has an inferred resource of 908 million tonnes of salt grading 96.9% NaCl (source: https://atlassalt.com/deposit/)

Atco’s second salt project, the Blue Moon South Project, is located 12 km south of Atlas Salt’s Great Atlantic Salt deposit, on the northwest corner of the Fischell’s Brook salt dome. The property consists of nine claim blocks totalling 225 hectares which are located near the Trans-Canada Highway. A recent press release from Atlas Salt indicates that a new spin-out company, “ Triple Point Resources ”, will be exploring the Fischells Brook Salt Dome as a possible hydrogen storage site.

Atco’s Blue Moon South Project is located 10.4 km to the south, southwest of Atco’s Lunar North Project claim boundary. It has a historical drill hole (“LR-98-01”) which was drilled to a depth of 771.23 meters and intersected a salt dome at approximately 668.66 meters through to 706.0 meters. This 37-meter-wide salt dome will be further explored for potential hydrogen storage as it is located at the required depth of between 500 to 1500 meters where most hydrogen is stored.
