More trouble for Mexico mine, work stopped because of toxic waste spill

Local farmers have joined forces with striking miners in stopping work at the Buenavista de Cobre open-pit copper mine near Canenea, Sonora, MX. The mine is owned by Grupo Mexico and is reportedly the second largest in the world.

Heavy rains last August resulted in the collapse of a tailings dam that unleashed a toxic runoff of contaminated mine waste including sulfuric acid and heavy metals into the headwaters of the Rio Sonora. The watershed provides drinking and irrigation water to the residents in northern Sonora.

According to Al Jazeera, striking miners, and Rio Sonora farmersĀ  shut down the groundwater wells used by the mine resulting in a sharp reduction in mining operations.

In August of last year, a leading mining industry publication said that collapse of tailing dams at Buenavista and Mt. Polley in British Columbia, CA “[serve] as a reminder of why lengthy permitting and environmental approval processes are necessary for mine construction…” similar to the process currently underway at the proposed Rosemont Mine in the Santa Rita Mountains on the Coronado National Forest south of Tucson.

    Is the Forrest Service listening and paying attention to all of the failures with the tailings dams/ponds that this company tries to pass off as environmentally safe? What about the EPA etc. ? We need to keep the pressure on! Please help fight to keep this environmental disaster from occurring in the Santa Ritas!

    IT IS BECOMING MORE AND MORE APPARENT THAT THE FOREST SERVICE IS PURELY A POLITICAL DECISION MAKING AGENCY THAT PROVIDES A SCREENING PROCESS BASED ON WHAT IS ” POLITICALLY CORRECT ” . THE DEPTH OF KNOWLEDGE REQUIRED TO MAKE SOUND TECHNICAL DECISIONS IS SADLY LACKING .

    TAILINGS , IN ANY FORM , ARE EVIL , DRY STACKED OR OTHERWISE . ROSEMONT IS BEHAVING LIKE A PHARMACEUTICAL COMPANY WHO IS INTRODUCING ” DRY STACKED TAILINGS ” AS THE THE SOLUTION TO ” HOW TO TREAT TAILINGS ” BEFORE THE CLINICAL TEST HAVE BEEN COMPLETE .

    DO NOT BE MISLED BY THE ‘ YEH ” ELEMENT .
