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.

EV Resources (ASX: EVR) has signed four non-binding MOUs with regional antimony producers in Puebla and Guerrero, Mexico, securing potential feedstock of 2,330–2,430 tonnes per month for its Tecomatlán Processing Plant. The agreements cover approximately 50–60% of plant capacity and support EVR’s hub-and-spoke strategy aimed at commencing antimony concentrate production in the second half of 2026.

Americas Gold & Silver reported strong infill drilling results at the Cosalá Complex in Sinaloa, with intercepts including 599.8 g/t silver and 0.83% copper over 14.0 m and 509.7 g/t silver and 0.43% copper over 10.0 m. Management stated recent drilling is consistently returning grades 2–3 times higher than inferred resource estimates, potentially enhancing future mine plans and resource upgrades.

Torex Gold Resources restarted drilling at its Los Reyes gold-silver project in Sinaloa, launching a 20,000-metre 2026 drill program focused on upgrading resources, reducing project risk, and supporting future economic studies. The company plans to invest approximately US$18 million this year and expects to release a Preliminary Economic Assessment (PEA) in July 2026.

Algo Grande finalized drill targets for its 8,000-metre Phase II drilling program at the Adelita Project in Sonora following completion of high-resolution drone magnetic and LiDAR surveys. Drilling, scheduled to begin in June, will focus on expanding the Cerro Grande copper-silver-gold skarn discovery along a 2.5-km corridor while also testing new targets including Cerro Potrero South and Las Trancas.

Tocvan Ventures reported discovery of three new gold-silver mineralized zones through step-out drilling at its Gran Pilar Project in Sonora, significantly expanding the project’s footprint beyond the Main Zone. The company has completed over 6,200 metres of its fully funded 20,000-metre drill program and continues advancing its fully permitted 50,000-tonne pilot mine, with commissioning targeted for 2026.

Minaurum Silver reported additional high-grade drill results from the Europa Sur, Travesia, and San José vein zones at its Alamos Silver Project in Sonora. Highlights included 3.20 m grading 882 g/t AgEq and 6.20 m grading 374 g/t AgEq at Europa Sur. The results expand mineralization along strike and at depth, supporting resource growth beyond the current 55.4 Moz AgEq inferred resource.

Axo Metals Corp. reported strong initial drill results from its San Antonio gold project in Sonora, including 23.6 metres grading 2.13 g/t gold from surface at the Sapuchi deposit. The company is advancing a 25,000-metre drill program aimed at expanding and upgrading resources and has engaged P&E Mining Consultants to prepare a Preliminary Economic Assessment (PEA).

Questcorp Mining and Riverside Resources completed an expanded drone aeromagnetic survey at the La Union Project in Sonora, adding 248 line-km of coverage to refine drill targets ahead of a fully funded summer drill program. The survey improved imaging of concealed structures potentially linked to mineralization, with IP geophysics and drill mobilization expected soon.
