Tocvan Ventures identified new surface gold-silver mineralization across Gran Pilar, expanding the Bojorquez target and defining a new Central Corridor zone 4 km north of the Main Zone. Rock samples returned up to 2.4 g/t Au, 67 g/t Ag and 1.6% Cu, while the Central Corridor has been traced for over 1,000 m.

Goldgroup Mining reported strong drilling at its Don David Gold Mine in Oaxaca, completing 25,726 m in 123 holes. Highlights include 1.92 m at 13.49 g/t Au and 931 g/t Ag at Arista, and 2.55 m at 1.66 g/t Au and 1,695 g/t Ag at Alta Gracia, supporting resource growth and mine-life extension.

Mithril Silver and Gold reported wide, high-grade silver-gold intercepts at Target 4 of its Copalquin project, including 11.70 m at 456 g/t AgEq, 13.95 m at 387 g/t AgEq, and 6.50 m at 320 g/t AgEq. Drilling confirms mineralization across 550 m of strike, with the Copalquin-Zaragoza structure remaining open in both directions.

Heliostar Metals has restarted open-pit mining at the Veta Madre pit at its La Colorada Mine in Sonora. Veta Madre contains 48,000 oz gold in reserves, while the expanded Veta Madre Plus pit targets an additional 20,000 oz. La Colorada remains on track for 20,000–22,300 oz gold production in 2026.

Sonoro Gold completed the acquisition of a 100% interest in 23 concessions totaling 4,239 ha adjacent to its Cerro Caliche Gold Project for US$5.17 million. Since January, Cerro Caliche has expanded from 1,350 to 8,215 ha, plus a 51% interest in another 454 ha, significantly increasing the project’s exploration potential.

Minaurum Silver reported high-grade results from Phase II drilling at its Alamos Silver Project in Sonora. Quintera returned 26.3 m grading 369 g/t AgEq, including 2.95 m at 1,379 g/t AgEq, while Europa Sur returned 3.4 m at 589 g/t AgEq. Results support potential expansion beyond the current 55.2 Moz AgEq resource.

GoGold Resources commenced construction of the fully funded Los Ricos South Mine in Jalisco following receipt of its federal permit in June. The company has US$284 million cash and zero debt. Plant design is 85% complete, earthworks are underway, and underground development begins January 2027. First silver-gold production is targeted for June 2028.

J2 Metals reported sampling up to 1,030 g/t silver at Sierra Plata, where mapping has identified seven veins and 20 historical workings across roughly half the property. Priority targets include El Sabino, San Miguel, El Salto and El Resumidero. J2 is designing systematic trenching while advancing permits for its maiden diamond drilling program.

Silverco Mining reports operational improvements at La Negra, targeting 2,500 tpd nameplate capacity by H1 2027. Initiatives include a renewed underground fleet, dry-stack tailings system, improved grade control and campaign milling. A 15,000-metre exploration program is underway, while SGS prepares an updated resource estimate and PEA expected in late Q3 2026.

Kingsmen Resources reported step-out drilling at its Las Coloradas Project in Chihuahua, including 1.40 m grading 433 g/t AgEq (239 g/t Ag), with 0.75 m at 787 g/t AgEq. A second hole returned 1.70 m at 185 g/t AgEq. Drilling has traced Mine Zone mineralization over 106 m of strike and 155 m depth, remaining open.
