Gunnison Copper Corp. Completes First Assay Results from Arizona Copper Project Drilling

en.Wedoany.com Reported - On November 10, Gunnison Copper Corp. of the United States announced the first assay results from its 2026–2027 drilling program at the Gunnison Copper Project and the Strong & Harris satellite deposits in Arizona. Among the results, drill hole SHM-2 at the Strong & Harris deposit intersected 40 feet (approximately 12.2 meters) of high-grade copper-zinc-silver mineralization grading 5.15% copper, 11.99% zinc, and 16.38 g/t silver; the hole also returned a continuous mineralized interval of 311 feet (approximately 94.8 meters) averaging 1.39% copper, 2.29% zinc, and 6.41 g/t silver.

The 311-foot mineralized interval in hole SHM-2 extends from 525 feet to 836 feet, with the 40-foot high-grade zone located at a depth of 576 to 616 feet. Based on the drill hole orientation and orebody dip published by the Company, the 311-foot downhole intersection corresponds to an estimated true thickness of approximately 269.3 feet, and the 40-foot high-grade interval corresponds to an estimated true thickness of approximately 34.6 feet. The results are consistent with the high-grade mineralized zones in the deposit's existing resource model and provide drill samples for further study of the integrated recovery of copper, zinc, and silver.

In addition to the Strong & Harris deposit, the Gunnison Main deposit also returned wider copper mineralization. Drill hole NSM-18 intersected a mineralized interval of 790.3 feet (approximately 240.9 meters) averaging 0.46% copper; drill hole NSM-22 intersected a mineralized interval of 738.3 feet (approximately 225.0 meters) averaging 0.43% copper. These drill holes are primarily intended to verify the continuity of existing orebodies, resource estimation, and subsequent mining plans.

As of the date of this announcement, the Company has completed 25 drill holes at the Gunnison Main deposit and the Strong & Harris deposit, totaling 27,953 feet (approximately 8,520 meters), representing approximately 20% of the total planned annual footage of 138,000 feet (approximately 42,062 meters). The full program comprises 120 drill holes, covering resource verification, metallurgical sampling, orebody extension, and peripheral exploration. Of these, 14 drill holes totaling 13,687 feet have been completed at the Strong & Harris deposit, and 11 drill holes totaling 14,266 feet have been completed at the Gunnison Main deposit.

Ore processing testwork is being conducted concurrently with drilling. The Company has engaged 7 laboratories for metallurgical testing, with research covering heap leaching, sulfide leaching, ore sorting, flotation, and solvent extraction, among other processes. For the copper-zinc-silver sulfide mineralization identified at the Strong & Harris deposit, the Company is conducting flotation tests with Finnish mineral processing equipment company FLSmidth to evaluate the technical route for constructing a concentrator, studying the possibility of concentrating copper and zinc into separate saleable concentrates and recovering associated silver therefrom. The Company plans to complete downstream metal processing within the United States.

The Strong & Harris deposit is located approximately 1.9 miles (approximately 3.1 kilometers) from the existing processing facilities at the Gunnison Project. Its currently published inferred mineral resource is approximately 76 million tonnes grading 0.49% copper, 0.56% zinc, and approximately 37.3 g/t silver, containing approximately 740 million pounds of copper, 856 million pounds of zinc, and 9 million ounces of silver. The deposit is incorporated into the overall mining plan for the Gunnison Project, and the potential to use existing processing infrastructure to treat ore from the satellite deposit can be studied in the future.
