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. Orogen royalties informed that the company will not proceed with the previously announced private placement. Silverco Mining commenced trading on the OTCQB.  ON RESOURCES AND DEVELOPMENT, Heliostar Metals reported drilling results from San Agustín, in Durango. Silver Tiger announced contracts for development engineering and management for El Tigre, in Sonora. Orla Mining received the environmental permit for the Camino Rojo project in Zacatecas. Southern Silver Exploration presented drill results from Cerro Las Minitas in Durango. Silverco Mining announced a 30,000 m drilling program at Cusi, in Chihuahua.

Silver Dollar contracted 3,500 m of drilling for La Joya, in Durango. Royalties Inc. received an economic update for the Bilbao project in Zacatecas. ON DEALS AND CORPORATE ISSUES, Orex Minerals entered into a definitive share purchase agreement with Silver Viper Minerals and Fresnillo plc to sell Silver Viper the Coneto project in Durango, for US$15 M in shares. Azucar Minerals announced the change name to Mustang Minerals Ltd. (El Cobre, Veracruz). Xali Gold announced an appointment to the board.

Antimony intercepts can be as high as 9 m @ 0.39% Sb. “it appears as though the lower gold rich breccia zone is spatially connected to the Dios Padre silver mine, though it may be locally shuffled and displaced via faulting.. The breccia itself appears to be primarily controlled by a swarm of Quartz-feldspar porphyry dykes that anastomose from depth towards the silver mine at surface”.

ON MINING

Two companies presented news on financing rounds, one on consolidation of shares, two on increased market activity and one on the granting of stock options. Three companies presented updates on advanced properties. Five companies informed on deals and corporate issues. ON MEXICO ISSUES, no relevant news. ON EXPLORATION, no relevant news. ON MINING, no relevant news. ON FINANCING, two companies informed on financing rounds: Apollo Silver (C$25 M) and Captain Silver (C$6 M). Chesapeake Gold and Silverco Mining informed on increased market activity. Centenario Gold consolidated its shares on a 10:1 basis. Impact Silver granted stock options.

ON MEXICO ISSUES

  • Editor’s Commentary: Mexico The Mexican mining industry is enduring challenging times, battling an in-house restrictive regulatory environment while precious metal prices break all records in the World scene. Unfortunately for Mexico, the present government has in its DNA dogmatic ideologic chains that prevent really positive changes, immersed as it is in its quest to centralize power. Good examples on this endeavour are the recently approved law on water rights, which heavily restricts the granting and exchange of extraction permits, and the intention to change the electoral law in order to make it more difficult for the opposition to challenge the MORENA party rule. The current administration regulatory environment in mining is not good, or even clear, but it has to be said that it is better than under the past administration and that the president seems to have the will to improve it. While the rule book for applying the 2023 law in mining is still being drawn, long awaited permits that allow for open pit expansions and tailings dam construction have begun to flow. Reflecting the overall global economy uncertainties and higher commodity prices, 2025 ends with an optimistic mood for the worldwide mining industry with some of that optimism spilling over into the Mexican side by means of a steady inflow of funds during the last few months to the coffers of  junior companies with properties in Mexico. Expect more drilling in 2026, and the development of some properties that have been on the shelves for some time now.
