Pacifica Silver received SEMARNAT permits for 491 additional drill pads at its Claudia Silver-Gold Project in Durango. The fully funded Phase II program was expanded to 30,000 m, with a fourth rig being mobilized. As of August 19, 18,258 m in 79 holes had been completed, supporting a targeted maiden resource estimate in 2027.

EV Resources has identified four new antimony feeder veins and four hydrothermal breccia targets at its Los Lirios Project in Oaxaca, expanding a 900m × 200m mineralized corridor. Thirty-one channel samples are being assayed, while Phase 2 drilling is being designed to test resource expansion targets and support a maiden JORC resource estimate.

Mercado Minerals completed its 25-hole inaugural drill program at the Copalito Project in Sinaloa, expanding and confirming mineralization at several veins. Highlights include 1.2 m grading 1,120 g/t AgEq at El Agua and 7.6 m grading 434 g/t AgEq at 5 Señores. Exploration also discovered the 1.15-km-long Renata vein, targeted for Phase II drilling.

Pinnacle Silver and Gold reported initial underground drilling results from the El Potrero project in Durango. At Pinos Cuates, assays reached 59.2 g/t Au and 424 g/t Ag over 1.07 m with visible gold. Drilling extended the known mineralized strike length to at least 70 m, with further underground and surface drilling planned.

Goldgroup completed 25,726 m of drilling in 123 holes at its Don David complex in Oaxaca. Results from the Arista and Alta Gracia mines included high-grade gold-silver intercepts, supporting near-term mine planning, production replacement and potential resource growth through extensions of multiple mineralized vein systems.

Goldgroup outlined a potential restart plan for the San Francisco gold mine in Sonora, targeting mining in Q1 2027 and full production during the second half. The plan contemplates 50,000–60,000 gold-equivalent ounces annually, approximately US$15 million for plant refurbishment and US$40–50 million in working capital.

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.

Luca Mining reported strong underground drilling at its Campo Morado mine in Guerrero, highlighted by 183.7 metres grading 1.18 g/t gold, 72.42 g/t silver, 0.39% copper, 0.45% lead and 1.67% zinc at Largo Norte. Results from several unmined zones demonstrate potential to expand near-mine resources and extend mine life.
