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

/ Gambusino Prospector / Leave a comment

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.
