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.

Silver Dollar Resources has hired Versa Drilling to execute a fully funded 3,500-meter diamond drilling program at its La Joya silver-copper-gold project in Durango, Mexico, starting April 2026. The program aims to test high-grade underground targets and expand mineralization, leveraging Versa’s expertise to refine resource potential and advance the project.

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.

Capitan Silver announced the arrival of a third drill rig at its Cruz de Plata silver-gold project in Durango, Mexico, further expanding its 2026 exploration campaign. The rig will help accelerate the company’s 60,000-metre multi-rig drilling program, targeting extensions of high-grade mineralization along the Jesús María Silver Trend, including the Peñoles and Gully fault zones.
