Gunnison Reports High-Grade Copper-Zinc in Arizona Drilling

Gunnison Copper reported early results from its 2026–27 Arizona drilling program, including a Strong & Harris hole that intersected 40 feet grading 5.15% copper, 11.99% zinc and 16.38 grams per tonne silver within a broader 311-foot mineralized interval. The result confirms high-grade mineralization already included in the deposit’s resource model. The company is conducting metallurgical tests, including flotation, to assess whether the sulfide material could produce copper and zinc concentrates; recovery rates and project economics are not yet established. Gunnison has completed nearly 28,000 feet of a planned 138,000-foot program, which is also testing broad copper mineralization at its flagship project.
