Sunshine Silver Mining & Refining Co 8K

Sunshine Silver Mining & Refining reported exceptional new drill results at the Sunshine Mine, advancing its 2027 feasibility study and supporting plans to expand production and restart operations in late 2028.

On July 23, 2026, Sunshine Silver Mining & Refining Company announced new high‑grade drill results from its ongoing 50,000‑metre drilling program at the Sunshine Mine in Idaho’s Silver Valley, including multiple intercepts exceeding 1,000 grams per tonne silver and particularly strong results from a newly identified, previously unmined “10 Vein.” The drilling, now about 60% complete and expected to finish in October 2026, is intended to upgrade mineral resource classifications and evaluate near‑mine resource expansion in the Upper Country area to feed the Company’s planned 2027 Sunshine Mine Feasibility Study and support a targeted Phase 1 doubling of production capacity from approximately 1,000 to 2,000 tonnes per day, with a planned return to silver production in late 2028. The Company highlighted that continued success in this program could materially enhance its near‑term mine plan and longer‑term production profile, including potential by‑product credits from copper, lead, and antimony, and confirmed that sampling, QA/QC procedures, and technical disclosures have been reviewed and approved by an independent qualified person under S‑K 1300.
