Gunnison Copper Corp. said it has completed planned metallurgical drilling at its Gunnison deposit in Arizona and expanded its testing program as part of its 2026 district-wide drilling campaign. The company said metallurgical work is under way across its Arizona assets, including flotation and related analysis to evaluate processing characteristics, and added that it is currently operating two drill rigs. The update builds on earlier disclosure that comparable work had started at the Strong & Harris deposit.
