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.

Silver Storm Mining Ltd. says its rehabilitation of the La Parrilla Silver Mine Complex processing plant in Durango, Mexico is ~50 % complete, advancing crushing, flotation, oxide and milling circuits. The progress is a key step toward a potential restart of operations in Q2 2026, including expanded sulphide processing capacity.

Capitan Silver reported very high-grade drill results at its Cruz de Plata project in Durango, Mexico, including an intersection of 2,451 g/t silver-equivalent over 1.5 m within a broader zone of 684 g/t AgEq over 9.1 m, highlighting expanding high-grade silver mineralization and ongoing diamond drilling to test and extend targets along the Jesús María trend.

Mammoth Resources has pinpointed several high-grade “draw point” locations at its 100%-owned Tenoriba gold-silver project in Chihuahua, Mexico for small-scale extraction and pilot heap leach testing. Using surface and drill data, geologists identified targets with attractive near-surface grades. Next steps include field checking and metallurgical tests to assess recoveries and potential tonnage.

Kootenay Silver Inc. has begun an ~8-week 3D induced polarization (3D-IP) and Audio-Magnetotelluric (AMT) geophysical survey over 1,250 ha at its Columba Silver Project in Chihuahua, Mexico, aiming to image subsurface structures and refine drill targets beyond its existing 54.1 Moz inferred silver resource with lead and zinc credits.
