Summary of Mining Plans of Operation in California.

Jump to: Plan/Notice Owners | Claims | Patents | Map

Location:   

Currently on file with the Bureau of Land Management (BLM) are 902 mining plans and notices filed by 108 companies and 225 individuals, encompassing a total estimated area of 35,420 acres of BLM-managed public land in California. These plans and notices are filed on public land laden with gold, silver, copper and other precious metals and minerals worth billions of dollars. And these operations are only those on BLM lands, not on Forest Service lands, for which mining plans and notices are not entered into the government's LR2000 database that forms the backbone of this site. But whether the mines are on BLM or Forest Service land, none of the corporate revenue is reimbursed to the public. Instead, companies leave behind unfathomable amounts of waste. In 2001 alone, the industry dumped enough mercury nationally to fill a billion thermometers and arsenic in quantities that would pollute all public drinking water supplies for 350 years. In 2001, mines generated 45 percent of all pollution reported in the U.S. while accounting for just 0.36 percent of all industrial facilities.

Source: EWG analysis of Bureau of Land Management's Land and Mineral Records 2000 (LR2000) data system. For claims, acreages are estimated based on maximum allowable size of claims. For patents, acreages are taken directly from the LR2000 database where available, and are estimated based on maximum allowable size of claim that preceded the patent where acreages are not noted in LR2000. All notices are assumed to be five acres in size, and the size of plans are calculated directly as the size of the land represented by the legal land description in the LR2000 database. The acreages we estimate through these methods would tend to overestimate the actual amount. We welcome corrections here, and would welcome a federal data management system that included the acreages involved in these important federal land transactions.
