  • No more mining concessions in my term: AMLO. The president of Mexico, Andres Manuel Lopez Obrador, announced this Sunday (August 11th, 2019) in a political rally in Concepcion del Oro, Zacatecas, that under his term no more mining concessions are to be granted. “To give concessions of the mining regions to national and foreign companies was a policy forwarded since the time of (Carlos) Salinas de Gortari, and up to 80 million hectares were delivered for mining exploitation. To grasp it: let’s think in our territory. Mexico has 200 million hectares, and 80 million hectares, about 40 percent of the national territory. Never in History so much of our sovereign soil had been transferred”, he said. He also reiterated that current concessions are to continue, but no new ones are to be delivered. “We are not to cancel (the concessions), but we are not to continue delivering new concessions for mining exploitation. Because it was too much what was delivered. If we analyze it, we are going to conclude that it wasn’t delivered to produce, but to speculate financially ………. With what has been delivered they have to produce. That’s the main purpose and not speculation. What we ask the mining companies is, first, take care of the environment, that no territory is destroyed, not to act as it is done in other countries”. He asked for Mexican miners to be paid as in the United States, or Canada, and that the same environmental rules be applied, also making a call for the salaries of workers to be raised, with the same benefits. (Editor’s note.- All the president arguments can be easily refuted to show that granting mining concessions is, and has been, very helpful for the country and countless of Mexicans. But there is no valid argument to present to the president that on the one hand is calling for more investment, while in the other hand is closing the door to it.)


  • Kootenay Silver Inc. has mobilized a drill rig to commence a 3,000 m core drill program at its Columba project in Chihuahua. “The first 12 holes of the drill program will be designed to test the F vein where underground development work extended to 200 meter depth and the historic mining occurred”.
