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.

Marcelo Ebrard, Secretariat of Economy, announced that the Mexican government has recovered over 1,100 mining concessions that were not in compliance with the law due to non-payment or were being used for speculation. This action is part of the policy implemented by President Claudia Sheinbaum to review and regulate the use of these national assets. During a joint presentation with José Fernando Aboitiz, head of the Coordination Unit for Extractive Activities at the Ministry of Economy, Marcelo Ebrard explained that the concessions, representing approximately 800,000 hectares, have been canceled. For his part, Aboitiz specified that the updated number of recovered concessions amounts to 1,126, which together cover 809,150 hectares, an area comparable to the territorial extension of the state of Querétaro. He also highlighted that within this process, nearly 20,000 hectares located in Protected Natural Areas have been recovered. Regarding the geographic distribution, the canceled concessions are concentrated mainly in states with a long mining tradition, such as Coahuila, Chihuahua, Sonora, Zacatecas, Durango, and Jalisco. On the other hand, the official specified that approximately 90% of the cancellations were made by individuals, not large companies.
