Algo Grande reported that the visually identified copper zone in Hole 2 at its Adelita Project in Sonora has doubled in width, extending mineralization within the Cerro Grande skarn system. Hole 3 is advancing as part of the Phase II program, with assays pending and two rigs accelerating exploration.
EV Resources secured 200 dry tonnes of 13–16% antimony ore from Chinantla for its Tecomatlán proof-of-concept processing campaign in Puebla. Located 8 km from the commissioned plant, the material previously achieved 81.1% recovery. Haulage will begin within two weeks, supporting production of EVR’s first marketable antimony concentrate.
Advance Metals reported new high-grade silver intersections at its Gavilanes Project in Durango, reinforcing the asset’s emergence as its flagship project. Drilling continues to expand shallow silver mineralization and identify deeper polymetallic potential. Results will support a planned JORC mineral resource upgrade targeted for early Q4 2026.
Oroco intersected 26.48 metres grading 1.18% copper equivalent in the South Zone of its Santo Tomás copper project in Sinaloa. The high-grade result strengthens confidence in South Zone mineralization as Phase 2 drilling supports resource upgrading and pre-feasibility-level mine planning.
Silver Storm intersected 215 g/t silver equivalent over 11.9 metres and 200 g/t silver equivalent over 15.4 metres during drilling at its La Parrilla Silver Mine Complex in Durango. The broad mineralized intervals support resource-growth potential and the evaluation of a future mine restart.
Defiance Silver received environmental approval for up to 172 drill sites at the Espiritu copper target within its Green Earth Project in Sonora. The authorization provides flexibility to test multiple targets across this prospective Laramide-age copper system and represents an important step toward initiating systematic drill exploration.
Guanajuato Silver received permits for surface drilling at its El Horcón project in Jalisco. The planned program will test extensions of the gold-silver-lead-zinc vein system, improve understanding of the historical resource and evaluate El Horcón’s potential as a satellite operation supplying the company’s processing facilities in Guanajuato.
Mithril upgraded Copalquin’s Target 1 resource to 464 koz AuEq indicated and 151 koz inferred, with indicated metal increasing 196%. High-grade drilling expanded Targets 3 and 5. Two rigs are completing the fully funded 12,000-metre 2026 program; Mithril held A$7.3 million cash and no debt.
Algo Grande mobilized a second rig and commenced Hole 3 at the Adelita project’s Cerro Grande skarn target in Sonora. Hole 2 intersected 28.37 metres of visual copper mineralization in skarn and andesitic porphyry and continued toward a planned 700-metre depth to test the system’s deeper extension and potential feeder intrusion.
Oroco reported a select surface sample grading 7.57% copper at its Vainilla concession in Sinaloa and completed a drone magnetic survey. The results, combined with geological mapping and sampling, will help define exploration targets associated with prospective breccia, skarn and concealed porphyry systems.
