More than 21,300 mining claims have been staked within 10 miles of California’s national parks and monuments and federal wilderness and roadless areas, according to an analysis of U.S. Bureau of Land Management records released Monday.
The claims, which have risen by more than one-third in the last four years, include more than 2,170 staked outside Death Valley National Park, 525 near Joshua Tree National Park and 285 outside Yosemite National Park. There are also 41 near the Giant Sequoia National Monument.
“If just a handful of these thousands of claims already staked turn into major mines, it could have devastating impacts on California’s national treasures,” said Dusty Horwitt, public lands analyst at the Environmental Working Group, the Washington-based nonprofit that issued the report.
In California and across the West, mining claims have skyrocketed in the last five years, driven by a boom in the global price of gold, copper, uranium and other metals. The rising demand, particularly from China and other developing nations, has spurred interest in reopening abandoned mining sites.
With its open pits, acid drainage, and air and water pollution, mining is the dirtiest of all resource developments, accounting for more Superfund toxic cleanup sites than any other industry. It also requires vast amounts of water for the processing of metal ore at a time when shortages are plaguing California and other western states.
The revival of hard rock mining also comes at a time when Congress is grappling with how to revise the General Mining Law of 1872 — a statute virtually unchanged since it was signed by President Grant. Unlike the oil, gas and coal industries, which must pay royalties to extract resources from public lands, hard rock miners can dig out ore virtually for free. And, under the law, which has been the subject of fierce debate for decades, mining has precedence over ranching, hunting, fishing, conservation and recreation on public lands.
