Mithril Silver & Gold reported additional high-grade drill results from the Target 1 area of its Copalquin project in Durango, Mexico, including 7.25 m grading 4.01 g/t gold and 225 g/t silver. The results continue to extend and upgrade mineralization within the El Refugio–La Soledad corridor and support the company’s ongoing resource expansion and update program.

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.

Advance Metals reported strong initial drilling results from the Gavilanes Silver Project in Durango, Mexico. Hole H1 intersected 33.9 metres grading 220 g/t silver, including 6.2 metres grading 718 g/t silver, confirming the down-dip extension of the high-grade Descubridora Zone. An 18-hole, 4,500-metre drill program is underway to support resource growth.

Centenario Gold reported high-grade copper mineralization from underground channel sampling at its Los Reyes Project in Chihuahua, Mexico. Results from historic mine workings confirm the presence of a copper-rich skarn/carbonate replacement system and will help guide a planned 1,500-metre drill program targeting extensions of known copper-zinc-silver mineralization.

Mercado Minerals has signed multiple Letters of Intent (LOIs) to acquire district-scale land holdings in the prolific San Dimas Mining District of Durango, Mexico. The agreements would significantly expand the company’s exploration footprint around one of Mexico’s premier precious-metals camps, providing exposure to numerous historical mines, vein systems, and underexplored targets with potential for new silver-gold discoveries.

Pinnacle Silver and Gold reported strong second-round metallurgical test results from the Dos de Mayo vein at its El Potrero Project in Durango, Mexico. Gravity and flotation tests achieved average gold recoveries of 97.8% and silver recoveries of 92.2%, confirming excellent metallurgical characteristics. The results support ongoing resource evaluation and future development planning for the high-grade gold-silver vein system.

Questcorp Mining and Riverside Resources completed an expanded IP survey at the La Union Project in Sonora, identifying new chargeability anomalies and refining drill targets. Combined with aeromagnetic data, mapping, and surface sampling, the results support final targeting for a fully permitted 2026 drill program aimed at testing the project’s gold exploration potential.
