About Bighorn Metals Corp.

The Company is an exploration-stage natural resource company engaged in the evaluation, acquisition, and exploration of mineral properties, with a view to advancing prospective mineral properties through exploration and evaluation.

The Company holds an option to acquire the Loljuh porphyry copper-gold project (the “Loljuh Project” or the “Project”). The Project consists of one claim covering a surface area of 1,656.73 hectares in the Omineca Mining Division of central British Columbia, Canada. It is approximately 40 km south of the community of Smithers and 32 km west of the community of Houston. The Project is prospective for porphyry copper-gold mineralization.

Geochemical work conducted in 2019 outlined several areas of anomalous gold and copper in soil. These surveys were widespread with lines 400 meters apart and samples taken on 200-meter centers. Rock sampling in 2019 also returned anomalous values of copper and gold from several sites within the plateau area. The aeromagnetic survey outlined several areas of alteration.

On October 5, 2026, the Company announced its proposed fall 2026 exploration program at the Loljuh Project. For further information, see that news release, available under the Company’s profile on SEDAR+ at www.sedarplus.ca.
