A U.S. appeals court has temporarily blocked the transfer of federal forest land in Arizona to a pair of international companies that plan to mine one of the largest copper deposits in North America. … The land includes Oak Flat — an area used for centuries for religious ceremonies, prayer and gathering of medicinal plants by the San Carlos Apache people and other Native American tribes. … Before the land exchange can happen, the plaintiffs argued that the federal government must prepare a comprehensive review that covers “every aspect of the planned mine and all related infrastructure.” They said the government failed to consider the potential for a dam breach, pipeline failure and if there was an emergency plan for a tailings storage area.
