EV Resources secured a lease (with purchase option) on a 150-tpd processing plant in Tecomatlán, Mexico, providing immediate production capacity to fast-track antimony output from its nearby Los Lirios project. The strategy enables low-capex startup, early cash flow from third-party ore, and positions the company as a potential key North American antimony supplier.

Riverside Resources completed the acquisition of key concessions (La Famosa, Dana 7) at the Union Project in Sonora, securing full ownership with no royalties. The consolidation strengthens its district-scale position and supports ongoing partner-funded exploration targeting CRD-style gold-silver-polymetallic mineralization across multiple targets.

Questcorp Mining and Riverside Resources consolidated key mineral concessions at the La Unión Project in Sonora, creating a larger, unified land package with multiple drill-ready targets. The project hosts favorable carbonate rocks, extensive alteration, and historic workings, enhancing its potential for a significant carbonate replacement (CRD) gold-silver discovery and supporting ongoing exploration and future drilling.

Silver Dollar Resources hired Versa Perforaciones for a fully funded 3,500-m diamond drilling program at its La Joya silver-copper-gold project in Durango, starting April 2026. The program targets deeper, higher-grade “San Martin–type” mineralization near intrusions, marking a strategic shift from open-pit concepts toward underground exploration beyond historic resource areas.

Silverco Mining has launched a fully funded 30,000-metre drill program at its Cusi Project in Chihuahua, targeting major step-out extensions and new regional “blue-sky” prospects. The program focuses on expanding known resources (San Juan, San Miguel) and testing a large offset extension across the Cusi fault, while advancing plans to restart production in H2 2026.

Heliostar Metals reported multiple near-surface gold intercepts at the San Agustin Mine in Durango, extending oxide mineralization over 200 metres beyond the current pit. Results from several zones support strong potential to expand resources and mine life, prompting an increase in the 2026 drill program to 15,000–18,000 metres.

Zacatecas Silver received a SEMARNAT drill permit for the El Cristo vein system at its Zacatecas Silver Project, enabling a 4,000 m 2026 drill program (2,800 m at El Cristo). The program targets resource expansion and new zones, aiming to define a maiden resource while building on the existing 20.5 Moz AgEq resource at Panuco.

Pacifica Silver expanded its Phase II drill program at the Claudia silver-gold project in Durango from 12,000 to 20,000 metres following financing and new permits. The program targets high-grade veins and new zones, with multiple rigs active and assays pending. The company also appointed veteran geologist Dr. Steven I. Weiss as Interim VP Exploration.

Colibri Resource reported results from its maiden RC drill program at the Plomo claims within the EP Gold Project in Sonora’s Caborca Gold Belt. Drilling intersected gold in 18 of 22 holes, including 7.5 m grading 2.92 g/t Au and 30 m grading 0.73 g/t Au from near surface, indicating a broad mineralized corridor at the San Perfecto target with strong potential for follow-up exploration.

Algo Grande Copper reported new exploration results at its Adelita Project in Sonora, Mexico, identifying additional copper-gold-silver skarn mineralization about 3 km south of the Cerro Grande discovery. Rock samples returned copper grades above 3%, confirming mineralization across multiple targets, including Potrero South and Las Trancas, highlighting the district-scale potential of the property.
