The Arizona Mining Coalition is comprised of Arizona groups and individuals that work to ensure that responsible mining contributes to healthy communities, a healthy environment, and, when all costs are factored in, is a net benefit to Arizona.  The Arizona Mining Coalition expects the mining industry to clean up after itself, comply full and in the spirit of safeguards in place to protect Arizona, and to interact in a transparent and open manner with Arizona citizens.


  • Mining is an inappropriate use of some lands in Arizona.
  • State and federal mining laws need to be positively reformed.
  • The coalition will promote alternative uses of some mineral deposits.

The coalition will increase awareness of all aspects of mining in Arizona.

Press Statement on Release of Resolution Copper FEIS

“With Arizona entering its 21st year of a long-term drought and the potential to pollute and deplete the town of Superior’s water supply, how can anyone let this happen, considering it would be a failed mining experiment?  The east valley municipalities of Queen Creek, Gilbert, and San Tan area beware, this project would wipe out your water supply. The project itself will consume 40,000 acre feet of water a year which is the same as Tempe, Arizona ,which has a population of 180,000 people.”

“Never Again”—what does a promise by Rio Tinto mean?

In the wake of Rio TInto’s destruction of sacred rock shelters in the Juukan Gorge in Western Australia in May of 2020, Rio Tinto has made grand pronouncement of how they would never again destory a sacred site anywhere in the world.  In light of the caompany’s plan to do exactly that at Oak Flat, what does Rio Tinto’s promises mean?

We’ve written a white paper looking at the similarities between what Rio Tinto did at Juuakn Gorge and what they would like to do at Oak Flat.

Advisory Council on Historic Preservation Blasts Forest Service on Rushed Resolution Copper Process

At every step of the NEPA process, we’ve cautioned the Forest Service to follow their laws and regulations and not bow to Resolution Copper and their supporters.  At every step, the Forest has let us down.  The results of the review by the Advisory Council on Historic Preservation shows us just how flawed the Resolution Copper process has been and just how eager Rio Tinto and BHP have been to place their project over the protection of our cultural and ecological heritage. This is yet another reason why Tonto National Forest needs to write an updated and complete Draft Environmental Impact Statement before rushing to judgement.
