About Copper One Resources Corp.

Copper One Resources is focused on identifying, acquiring and advancing high-potential copper, copper-silver-gold and copper-molybdenum projects to help meet global demand for critical metals used in electrification, AI (artificial intelligence) infrastructure and data centres, renewable energy, defence, and power-system modernization.

The company's flagship asset is the Majuba Hill copper-silver-gold district, located approximately 156 miles (251 kilometres) from Reno, Nev. Majuba Hill is an exploration-stage porphyry copper project situated in an established mining jurisdiction with existing infrastructure, where continuing exploration is focused on evaluating the scale and continuity of a copper-silver-gold mineralized system.

Copper One also owns a 100-per-cent interest in the Redonda copper-molybdenum project, located northeast of Campbell River in British Columbia's Vancouver mining division. The district-scale project comprises approximately 2,746.46 hectares (6,786 acres) across nine mineral claims and hosts a porphyry-style copper-molybdenum system within the Coast Suture zone, a geological belt known for porphyry copper and skarn mineralization. Systematic exploration is continuing to evaluate the scale and continuity of the mineralized system.

In addition, Copper One holds an option to earn up to a 100-per-cent interest in the Redhill property, located south of Ashcroft, B.C., adjacent to the Trans-Canada Highway. The 4,736-hectare (11,704-acre) property hosts volcanogenic massive sulphide (VMS) mineralization prospective for copper, zinc, silver and gold, while also demonstrating potential for epithermal gold mineralization.

Copper One also owns a 100-per-cent interest in the Sport project in Utah through its wholly owned subsidiary, Rooinek Mining Corp., expanding the company's portfolio of North American copper exploration assets.

Copper One is advancing its portfolio through systematic exploration, modern geological modelling and disciplined technical evaluation. The company remains committed to responsible exploration practices, technical transparency and the disciplined advancement of critical metals projects across North America.

We seek Safe Harbor.
