Capitan Silver’s Cruz de Plata project reveals a vastly expanded mineralized system: silver veins now exceed 20km (up from 7km), wrapping around a key granodiorite intrusion, with all lithologies mineralized. Six new drill-ready targets identified via surface work. Phase 1 drilling upsized 50% to 15,000m (fully funded); assays pending for 38 holes. Geophysical survey underway for Q1 2026.

Sierra Madre Gold and Silver starts underground development at Nazareno mine in La Guitarra complex, delivering 700+ tonnes of mineralized material with grades 40% higher Ag and 30% higher Au than 2023 model. Plans expansion to double plant capacity by Q3 2027; purchased new drill rig; engaged marketing firm for $120K USD.

Questcorp Mining’s maiden drilling at La Union gold-silver project in Mexico is on track and budget. Three of five targets drilled, showing consistency with historic mining and favorable quartzite for fracture-controlled mineralization. Assays pending; now at Famosa target, with follow-up planned.
