supreme court Arizona Oak Flat copper mining Apache.

The group Apache Stronghold is vowing to carry on the fight against a massive copper mining project on land the Apaches hold sacred, after a Supreme Court decision that is expected to let the mine proceed. On Tuesday the court rejected an appeal from Apaches who want to halt the project. The justices left in place lower court decisions allowing the transfer of land in the Tonto National Forest known as Oak Flat to Resolution Copper. The company says the ground there holds the world’s second-largest known copper deposit. Resolution Copper’s general manager says the company has made major changes to its mining plan to reduce the impact on tribes.
