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.
Heliostar reported strong drill results from the Ana Paula Expansion Zone, including 101 m grading 5.34 g/t gold, confirming thick, high-grade mineralization beyond the current mine plan. Results extend mineralization at depth and laterally, support potential resource growth, and highlight expansion upside near planned underground infrastructure. Additional assay results are pending.
Masivo Silver completed and extended its first drill hole at the Cerro Colorado project in Sonora, intersecting visible mineralization and confirming strong alteration and sulfide continuity. The results support the scale potential of the system as the company advances its Phase I drill program targeting multiple high-priority silver-gold zones.
Tocvan Ventures has added a second drill rig at its Gran Pilar gold-silver project in Sonora, accelerating its fully funded 20,000-meter drill program. Multiple high-priority targets, particularly in the South Block, will now be tested in parallel following a recent discovery. The expanded program aims to rapidly grow the mineralized footprint and support a future resource estimate.
Advance Metals announced a maiden JORC (2012) mineral resource of 33Moz silver equivalent at its Yoquivo project in Chihuahua, confirming a large-scale silver-gold system. The resource totals 8.8Mt at 120 g/t AgEq, including 23Moz silver and 140koz gold, with broad, shallow mineralization supporting potential bulk mining and further expansion through ongoing drilling.
