Kootenay Silver (TSXV: KTN) announced drill results from the first 7 holes of its 50,000m program at Columba Project, Mexico, revealing high-grade silver intercepts (up to 921 g/t Ag over 0.71m) on D Vein/I Vein plus a new discovery of broad porphyry-style gold zones (e.g., 101m @ 0.18 g/t Au; up to 0.85 g/t Au over 6m) with molybdenite, indicating potential for a separate gold-porphyry system. Drilling continues with plans to add rigs.

Silverco released additional drill assay results from its 2025 Cusi drill program in Chihuahua, Mexico, including standout intercepts like 3.4 m at 425 g/t AgEq and 1.5 m at 764 g/t AgEq, confirming strong high-grade silver-lead-zinc-gold mineralization. The results support continued potential expansion of the Cusi deposit and feed into an upcoming Mineral Resource Estimate update.

Defiance Silver completed a major trenching program at its San Acacio project in Zacatecas, Mexico, sampling 2.1 km of the Veta Grande vein. Results confirm strong surface continuity with highlights up to 5,180 g/t Ag and 4.85 g/t Au, supporting the upcoming mineral resource estimate.

Zacatecas Silver finalized land-access agreements for its El Cristo Target drill program at the Zacatecas Silver Project in Mexico, enabling full access to the 3km vein system. With SEMARNAT permits underway, the company aims to test high-grade silver extensions, building on prior results like 829 g/t AgEq over 0.65m.

Pinnacle Silver and Gold reported high-grade sampling at La Dura mine, El Potrero Au-Ag project, Mexico: 162 g/t AgEq over 12.48m, extending Dos de Mayo vein mineralization to 500m. New zone discovery with up to 4.51 g/t Au and 269 g/t Ag; undrilled potential for expansion.

Mexican Gold acquired 100% interest in Chesapeake’s Tatatila Project (3,824 ha) in Veracruz, Mexico, adjoining Las Minas, for 4.45M shares ($222K value, 14.99% stake) and 1.5% NSR royalty (0.5% buy-back at US$500K). Shares subject to hold periods and 2.5-year lock-up; pending TSXV approval.

Silver Spruce signed an amending agreement to acquire Colibri’s 50% interest in the Jackie Au-Ag Project in Sonora, Mexico, for 166,667 shares at $0.15 each and 1% NSR royalty, gaining 100% ownership. Plans include environmental permitting, fieldwork, trenching, and initial drilling on high-grade epithermal targets.

Questcorp Mining Inc. completed Phase 1 drilling at La Union gold-silver project in Mexico: 12 core holes totaling >1,600m across six targets. Over 700 samples shipped for assays. Riverside Resources operated; results to inform Phase 2 in H1 2026.

Riverside Resources completed Phase 1 drilling at its Union Project in Sonora, Mexico: 12 holes totaling over 1,600m across six targets (Union Mine, Famosa, etc.). Funded by partner Questcorp; over 700 samples shipped for assays. Results to guide Phase 2 exploration in H1 2026.

Silver Dollar Resources discovered the North Canyon zone at its Nora property in Durango, Mexico, 1,500m north of the Candy mine. Channel sampling returned 162 g/t AgEq over 12.48m. A 3-year drill permit has been received to advance exploration.
