American silver miner Sunshine Silver Mining & Refining has reported results from its  ongoing 50000m drilling program at the Sunshine Mine, in Idaho's Silver Valley.

The new results include multiple intercepts exceeding 1000gpt silver and support a classification upgrade of the mineral resource in the planned 2027 Sunshine Mine Feasibility Study. The assay results also indicate possible opportunities to expand the near-mine resource in the Upper Country, doubling overall production volume  from 1,000 to 2,000tpd.

Heather White, Sunshine Silver Mining & Refining CEO said: "We are naturally excited by the results. The in-fill drilling is confirming our expectations, particularly in areas such as the 10 Vein, a completely unmined new vein that is already yielding among the best known intercepts in the history of the Sunshine Mine.

The Upper Country is a historically under-mined and under-explored portion of the Sunshine Mine, located between surface and approximately 1900 feet below ground.

The area is accessible through the Sterling Ramp, an access independent of the Jewell Shaft, and includes the new 10 Vein, as well as the C-Fault and the North and South Yankee Boy Vein Systems

As of July 2026, the ongoing drilling program is approximately 60% complete, with three active drill rigs underground and remains on track for completion in October 2026.

The drill campaign is designed to support the technical work required for the planned 2027 Sunshine Mine Feasibility Study and the Company's planned return to silver production in late 2028.
