The Mining and Exploration News in Mexico; Highlights on the Third Week of March 2026

By Jorge Cirett
Since 2015 Miguel Heredia and I have published the weekly newsletter ‘The Mining and Exploration News in Mexico’. It has been a very rewarding experience and we have learnt a lot in the process on Mexico and on the global mining industry. Although a pro-bono project, the previous format consumed a lot of time. We realized we could not keep reasonably doing this task in the same manner when recently had to put more than 10 hours in the week for producing the newsletter, while doing long hours on project work at the same time. To sustain this contribution, we are introducing a new, streamlined format with all the key mining activity in Mexico, with links to all the original press releases and sources. It is our intention to continue serving the industry as long as it remains fun and rewarding as it has been so far.
During the 12th week of the year (March 16th to March 22nd, 2026), companies working in Mexico released 32 press releases. Four companies informed on early-stage property work, four more presented quarterly and/or full-year 2025 reports. Three companies updated on financing rounds/movements, another is not proceeding with a financing round and one more is to list in the OTCQB. Two companies presented drilling results on their advanced projects, while four more informed on their incoming drill programs. One company informed on development contracts while one more received a long awaited mining permit. Finally, one company received an economic update for its project. ON MEXICO ISSUES, no relevant news. ON EXPLORATION, in Sonora, Questcorp Mining and Riverside Resources completed the acquisition of key claims on La Union. In Durango, Pinnacle Silver and Gold discovered mineralization after a LiDAR survey at El Potrero. In Michoacán, Canadian Silver Hunter released assay results from surface sampling of stockpiles at an undisclosed project. ON MINING, Heliostar Metals (Ana Paula, Guerrero), Orla Mining (Camino Rojo, Zacatecas), Gold Resource (Don David, Oaxaca) and Elemental Royalty (royalty on Mercedes, Sonora) presented Q4 and/full year 2025 results. ON FINANCING, three companies informed on financing rounds/movements: Barksdale Resources (San Javier, Sonora) completed a shares for debt transaction of US$351 K and completed a private placement for C$763 K.
