Two mining industry groups have appealed a federal judge’s ruling upholding an Obama administration ban on new hard-rock mining claims on more than one million acres near the Grand Canyon.
The appeal filed this week by the National Mining Institute and the Nuclear Energy Institute asks the 9th U.S. Circuit Court of Appeals to overrule U.S. District Court Judge David Campbell’s decision dismissing their challenge to the 2012 ban.
