EV Resources is accelerating near-term antimony production by refurbishing the Tecomatlán processing plant in Mexico. A restructured, milestone-based agreement minimizes upfront costs and links payments to permits and performance. Plant upgrades are underway, supported by high-grade feed from Los Lirios and strong recoveries (~90.8%), positioning EVR as a low-capex, first-mover supplier in a tightening global antimony market.

Silver Viper reported high-grade infill drill results at the El Rubi zone, including 11.7 m grading 9.18 g/t gold and 352 g/t silver, with extremely high-grade sub-intervals. The program has exceeded 5,600 m and continues, supporting resource expansion potential at La Virginia while also identifying new mineralized structures at nearby El Molino.

Southern Silver reported strong drill results at Cerro Las Minitas, including 6.3 m grading 874 g/t AgEq, confirming high-grade, silver-rich polymetallic mineralization. Results from the Puro Corazón area continue to expand known zones and support resource growth, with ongoing drilling expected to enhance the upcoming resource update and project economics.

Algo Grande launched advanced geophysical and geochemical programs at its Adelita Project in Sonora to refine drill targets ahead of a Phase II campaign in Q2 2026. Work includes LiDAR, geophysics, and surface sampling aimed at improving structural understanding and identifying high-priority zones for upcoming drilling.

Tocvan completed a high-resolution drone magnetic survey at its Gran Pilar project, identifying extensions of known mineralized structures and new target zones across underexplored areas. The data enhances integration with geology and geochemistry, helping refine drill targets and support expansion potential ahead of a planned 20,000-m drilling program and ongoing project development.

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.

Pinnacle discovered new silver-lead-zinc mineralization at El Potrero while following up LiDAR targets, identifying breccia veins over ~650 m with assays up to 266 g/t Ag, 4.39% Pb, and 2.89% Zn. The find confirms historic workings, introduces a new polymetallic target, and suggests potential linkage to nearby Topia-style mineralization.

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.
