The hardrock mining industry owns gold, silver, and other precious metals and minerals beneath an estimated 245,869 acres of U.S. public land in Montana, resources worth millions of dollars a year, acquired for as little as $0.84 per acre and held in perpetuity for a yearly rental fee as low as $0.62 an acre. Under a 132-year-old law originally intended to spur development of the West, an industry dominated by a handful of multinational corporations pays no federal royalties, and leaves behind a landscape of dramatically diminished value, scarred with tunnels, pits, and toxic waste piles.

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.
