Mining also notable: Gunnison grades and Plateau attack

Mining Wednesday, November 11, 2026 - Updated Nov 11, 2026 07:18

Gunnison Copper cut 94.8 metres at 1.39 percent copper and 2.29 percent zinc at Strong and Harris in Arizona, and three people were feared killed in a gun attack on a mining site in Nigeria's Plateau State.

Why it matters: The roundup holds the day's verified second-order items: a high-grade Arizona drill result that tests a second processing route, and a fatal attack that underlines the security cost carried by Nigerian artisanal and small-scale mining.

Data as of Company release and Nigerian reporting of November 10, 2026, read via full text carriers in this run. Drill grades are sample grades, not recoveries or reserves.

Gunnison Copper confirmed a high-grade copper and zinc zone at its Strong and Harris deposit in Arizona on November 10. Drill hole SHM-2 cut 94.8 metres grading 1.39 percent copper and 2.29 percent zinc from 160 metres depth, including 12.2 metres at 5.15 percent copper, 11.99 percent zinc and 16.38 grams per tonne silver. The company estimates true thickness at 82.1 metres for the main interval. Strong and Harris holds 69 million inferred tonnes at 0.49 percent copper and 0.56 percent zinc. The result confirms mineralisation already in the resource model; its purpose is to test whether flotation of sulphide material could produce saleable copper and zinc concentrates alongside the heap leach route in the project’s March preliminary economic assessment. Recoveries and economics are not yet established. The wider program has completed 25 holes for 27,953 feet of a planned 120 holes totalling about 138,000 feet.

Three people were feared killed when gunmen attacked a mining site in Plateau State, Nigeria, in reporting carried by Vanguard and Daily Trust on November 10 and 11. The attack is the latest fatal incident around informal mining in the state, where Zamfara State authorities in the northwest have separately moved this week to reclaim gold fields from illegal mining and inaugurated a 13-member committee to check illegal mining. No company has been named as the site operator in the reporting read, and no production impact has been claimed.
