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.

EV Resources announced it has acquired the remaining 50% interest in the Don Enrique Copper-Silver Project in Peru, securing 100% ownership for about US$150,000. The consolidation creates a 2,684-hectare land package with 5.5 km of prospective strike over a large undrilled geophysical anomaly. Historic sampling returned copper grades up to 3.22%, and the project is drill-ready with permits in place.

Mercado Minerals has begun a 3,000-meter diamond drilling program at its Copalito project in Sinaloa, Mexico. About 25 drill holes will test several segments of known silver-gold veins including 5 Señores, El Agua, La Chiva, and El Pilar, while also evaluating new targets. The program builds on 81 historical drill holes and aims to better define mineralization and guide future exploration.

Advance Metals reported broad silver-gold drill intersections at its Yoquivo Project in Chihuahua, Mexico, confirming strong mineralization continuity and indicating potential for a significant resource upgrade. The results support expanding the geological model and evaluating larger-scale development scenarios as the company works toward an updated JORC mineral resource estimate expected in 2026.

Luca Mining reported new drilling results from its Tahuehueto Mine in Durango, Mexico, intersecting 7.6 m grading 16.1 g/t gold equivalent, confirming high-grade breccia mineralization below current workings. The results demonstrate continuity in the Creston vein system and potential to expand near-mine resources, prompting a 40% increase in the 2026 drill budget to $3.5 million.

Pan American Silver reported the discovery of at least four new high-grade silver veins at the La Colorada mine in Zacatecas, Mexico. Drilling between the Cristina and San Gerónimo systems returned strong intercepts, with 40% of holes exceeding 1,000 g/t silver. The Filomena, Nicolasa, Bernardina, and Josefina veins may expand mineral resources and support future high-grade development.
