Silver Dollar Resources has begun a fully funded 3,500-metre diamond drilling program at its La Joya silver-copper-gold project in Durango. The campaign targets new zones beyond historic resources, particularly in the Noria area, aiming to test deeper San Martin–style mineralization and expand the scale and understanding of the broader 2×3 km mineralized system.
Kingsmen Resources commenced a new drilling program at its Las Coloradas silver-gold project in the Parral Mining District, Chihuahua. The campaign targets multiple high-priority vein systems identified through prior geophysical and geochemical work, aiming to expand known mineralization and test new zones within the historic district, which hosts past-producing Ag-Au-Pb-Zn mines.
Pinnacle Silver and Gold reported new high-grade polymetallic discoveries at its El Potrero project in Durango, with surface sampling returning up to 1,159 g/t silver. Follow-up work on LiDAR targets identified multiple Ag-Au-Pb-Zn vein systems, extended mineralization over >1 km, and confirmed strong district-scale potential across the property.
EV Resources has defined a large-scale, shallow carbonate replacement (CRD) antimony system at Los Lirios, with 10 of 11 drill holes intersecting a laterally extensive mineralized limestone unit. High-grade surface samples (up to 30.2% Sb) and strong structural controls indicate significant scale potential, supporting a system-wide target and advancing toward a maiden resource.
Questcorp Mining is advancing Phase 2 exploration at its La Union project in Sonora, following a new sediment-hosted gold discovery (42 m @ 0.3 g/t Au). Work includes geophysics, geochemistry, and mapping across five targets to refine drill sites, with potential for CRD and porphyry systems, supporting a growing pipeline of drill-ready targets.
Mercado Minerals completed re-sampling and re-assaying of historic drill core at its Copalito project, confirming strong consistency with previous results. The program validates earlier drilling data and supports confidence in the project’s mineralization, while helping refine geological understanding and future exploration targeting.
Pacifica Silver reported initial Phase II drill results from its Claudia project in Durango, with 14 of 16 holes intersecting silver-gold mineralization. Drilling extended the Aguilareña vein up to 150 m down-dip and confirmed continuity over ~1.9 km. Multiple high-grade intercepts (some >1,000 g/t AgEq) highlight strong potential and support further expansion of the system.
EV Resources reported continued progress toward near-term antimony production, advancing its Los Lirios Project in Mexico. Permitting is well underway, with drilling and bulk sampling planned, and plant refurbishment progressing toward a mid-2026 production target. Recent financing has secured funding, and the company is focused on fast-tracking development while strengthening local stakeholder agreements.
Sonoro Gold acquired the 51-hectare Diana concession adjacent to its Cerro Caliche project in Sonora for US$600,000, expanding its land package and exploration potential. The concession may extend known mineralized corridors and support a planned 50,000-meter drill program aimed at increasing resources as the project advances toward open-pit heap leach production.
Mithril’s drilling at Target 3 in the Copalquin project confirmed high-grade, widespread silver and gold mineralization, extending known veins from historic workings. Results demonstrate strong continuity and depth potential, with higher grades encountered at depth, supporting significant expansion upside and reinforcing Copalquin as a large, district-scale epithermal system with multiple growth targets.
