GR Silver reported high-grade results from step-out drilling at San Marcial, including 15.6 m at 351 g/t silver (with 2.5 m at 1,395 g/t). The results confirm strong continuity of mineralization up to ~500 m depth and support expansion of the epithermal system ahead of a planned 2026 resource update.
Heliostar Metals Ltd. reported strong high-grade drill results from the Ana Paula project in Mexico, including 69.15 m grading 10.09 g/t gold and multiple intervals exceeding 20 g/t. Results confirm continuity of a robust high-grade panel, supporting resource upgrading and ongoing feasibility work while exploration continues to expand mineralization.
Oroco Resource has ramped up activity at its Santo Tomás copper project, mobilizing a second drill rig to accelerate its Phase 2 program. Six drill holes are complete with more underway, and recent core samples have been sent for assay. The expanded drilling targets the South Zone as the project advances toward pre-feasibility.
Starcore International Mines has initiated an airborne MobileMT geophysical survey over its San Martin mine in Querétaro, covering ~711 line-km across 99 km². The program aims to map deep structures, identify extensions of mineralization, and generate new drill targets, enhancing understanding of the district’s epithermal gold-silver system.
Mercado Minerals reported progress from its inaugural 3,000-m drill program at the Copalito Project, with ~1,479 m completed across 12 holes, mainly targeting the 5 Señores vein. Drilling is testing extensions and depth potential while shifting to the El Agua vein. Early samples have been submitted for analysis, and expanded soil sampling and mapping are refining new drill targets.
IMPACT Silver reported high-grade drill results from the Carlos Pacheco vein extension at its Noche Buena mine, including 114.5 g/t gold, 1,295 g/t silver, and 1.10% copper over 0.61 m within a broader 9.49 m interval. The results confirm strong mineralization continuity and support ongoing expansion of the Zacualpan district.
Silver Storm reported high-grade drill results extending the San Nicolas Zone at depth, including 473 g/t AgEq over 3.6 m and 137 g/t AgEq over 12.0 m. Results confirm strong mineralization continuity and expansion potential below previous workings, supporting ongoing exploration aimed at growing the resource.
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.
