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.

Kootenay Silver reported additional drill results from its Columba High-Grade Silver Project in Chihuahua, Mexico, including 10 m grading 503 g/t silver and 9.88 m grading 319 g/t silver from the Lupe Vein system. The ongoing drill program—expanded to 60,000 meters—is focused on step-out drilling to expand resources, currently estimated at 54.1 million inferred ounces of silver at 284 g/t.

Regency Silver reports that 2025 drilling at its Dios Padre project in Sonora, Mexico has identified new silver-rich zones beneath the historic mine, extending the system 125 m down dip. Highlight assays include 158 g/t silver with copper over 9 m and 5.4 g/t gold over 9 m, supporting continuity of mineralization and potential for substantial new silver-rich zones.

Minaurum Silver has expanded drilling at its Alamos Silver Project in Sonora, Mexico, to six rigs as part of a 50,000-metre Phase II program. Step-out drilling continues on key veins like Europa and Travesía-Quintera, with standout high-grade silver-equivalent intercepts reported, supporting plans for an updated resource estimate later in 2026.

Riverside Resources reported expanded porphyry copper-gold targets at its 100 %-owned Ariel Project in Sonora, Mexico, including high-grade rock samples (e.g., up to ~320 g/t Ag and 5.4 % Pb) and alteration signatures typical of major copper systems. Work has refined multiple priority zones and integrated mapping, geochemistry and geophysics, positioning Ariel as a drill-ready, district-scale target near the La Caridad copper belt.

Masivo Silver Corp. has started its Phase I diamond drilling at the Cerro Colorado Project in Sonora, Mexico, with about 8 holes totaling ~1,500–2,000 m to test high-priority silver-copper targets defined by geological work and historical data. This first drill phase aims to validate geological models and explore mineral continuity at depth.

Silverco Mining reported the final 2025 drill results from its 15,000 m program at the Cusi Property in Chihuahua, Mexico, showing high-grade silver-equivalent intercepts (e.g., 370 g/t over 13.6 m, 803 g/t over 3.7 m, 255 g/t over 6.8 m). Results extend mineralization at San Miguel and San Juan and highlight further district potential. No production decision has been made yet.
