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.
