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.
