STELMINE IS PLANNING A MAIDEN EXPLORATION CAMPAIGN ON ITS NORTHERN CANIAPISCAU PROPERTIES

Stelmine Canada Ltd. is currently planning its summer 2024 work program. This year, a first exploration phase will be performed on three new properties (100 per cent Stelmine). The Atanau, Nikan and Mishtik properties are situated in a territory where several gold, silver, zinc and copper showings were discovered notably by Osisko James Bay and Virginia Mines. The region is presently undergoing a resurgence in mining exploration searching for critical metals. The new program defined by Stelmine confirms the resolve to diversify its project portfolio to include strategic metals assets.

The properties consisting of 228 claims (116 square kilometres) are located in the Ashuanipi subprovince, 50 km north of the Mercator property. The proposed exploration program will involve prospection traverses and systematic sampling of rock and till material. Note the geological and structural context of these properties lend itself to critical metal exploration (lithium, copper, zinc, nickel, rare earths) being characterized by:

• An association with large regional faults, principally oriented northeast-southwest;
• Occurrence of strongly deformed and folded narrow greenstone belts;
• Tonalitic and granitic complex intruding volcanosedimentary rocks;
• Orogenic and volcanogenic mineralization
• ; Metamorphism at the amphibolite grade.

Participation in PDAC

Stelmine announces its participation, for another year, in the Prospectors and Developers Association of Canada (PDAC) convention currently taking place in Toronto from March 3 to 6, 2024. The team is already at booth 2821, presenting its projects. The company looks forward to seeing you there.
