During the first week of April 2025, two companies released results from drilling programs from their projects in Mexico. Gold Resource presented intercepts from the 2024 exploration program at the currently operating Don David Mine in Oaxaca. The results are from 23 underground infill and expansion holes that focused on the Three sisters and Gloria vein systems, close to the current mine portal and at significantly higher elevations than current production areas. Mineralization is of intermediate sulfidation epithermal character.

At Panuco, in Sinaloa, Vizsla Silver delivered results from the drilling program on the Animas vein system, below historic workings and 6 km northeast of the Copala resource area. “Animas has a mapped strike length of over 7.2 km and extends from the San Carlos mine in the southeast to the claim boundary in the northwest”. Interpretations by Vizsla geologists indicate that mineralization may be telescoped and that high-grade mineralized shoots could repeat/re-open at depth. Results confirm that potential exists along the Animas vein system below the historic mines and below the current water table that consistently prevented the historic miners from going deeper. “The district contains intermediate to low sulfidation epithermal silver and gold deposits related to siliceous volcanism and crustal extension in the Oligocene and Miocene. Host rocks are mainly continental volcanic rocks correlated to the Tarahumara Formation”.
