Geophysical surveys at EV Resources’ Los Lirios antimony project in Oaxaca have identified multiple new exploration targets and suggest the mineralized system may be significantly larger than previously recognized. Results from CSAMT and magnetic surveys expanded the prospective strike length along the Lirios Fault Zone, supporting the potential for additional high-grade antimony mineralization and enhancing targeting for ongoing drilling and future resource growth.

Zacatecas Silver reported high-grade surface sampling results from the Oso Negro project in Sonora, where gold and silver mineralization has been traced over a strike length exceeding 2 kilometres. Highlights include samples grading up to 16.8 g/t gold and 1,395 g/t silver, supporting the project’s potential for a significant epithermal precious metals system. The results will help guide upcoming exploration and drill targeting programs.

Riverside Resources and Questcorp Mining have begun a fully funded 1,500-metre Phase 2 diamond drilling program at the La Union Project in Sonora, Mexico. The campaign will test both sediment-hosted gold and CRD-style gold-silver-zinc mineralization, following encouraging Phase 1 results. Drill targeting incorporates recent mapping, drone magnetic surveys, and IP geophysics, with results expected to generate steady news flow through summer 2026.

Questcorp Mining has commenced a fully funded 1,500-metre Phase 2 diamond drilling program at the La Union Project in Sonora, Mexico. The campaign will test both sediment-hosted gold and carbonate replacement (CRD) gold-silver-zinc mineralization across multiple targets identified through drilling, mapping, aeromagnetic surveys, and IP geophysics. Results are expected to provide continuous news flow through the summer exploration season.
