Kootenay Silver’s Columba drill program in Chihuahua, Mexico returned strong results, including 10 m averaging 503 g/t silver with lead-zinc and 9.88 m at 319 g/t silver with lead-zinc. The 50,000 m staged drilling continues to expand known veins, which remain open along strike and at depth.
Zacatecas Silver Corp. agreed to buy a 100% interest in Heliostar Metals’ Cumaro, La Lola, Oso Negro and Ejutla exploration properties in Sonora and Oaxaca, Mexico, creating a larger district-scale exploration platform with near-term drill targets and longer-term strategic potential. Oso Negro is a priority, undrilled high-grade opportunity. The deal expands Zacatecas Silver’s Mexican asset base.
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.
Mithril Silver & Gold Limited has appointed James Barr, P.Geo., as its new Vice President, Exploration, bringing over 20 years of global experience, especially in Mexico’s high-grade epithermal gold-silver systems. He previously held senior exploration roles at SilverCrest Metals, contributing to growth at the Las Chispas Mine. His expertise supports Mithril’s Copalquin exploration strategy.
Heliostar Metals announced a binding option agreement with Zacatecas Silver Corp., granting Zacatecas the right to acquire 100% of four non-core Mexican exploration projects (Cumaro, La Lola, Oso Negro and Ejutla). Payments over three years total $450K cash and $750K in shares, with Heliostar retaining a 2% NSR royalty (1% repurchasable). The deal should close by March 31, 2026 pending conditions.
