Jump to: Patent Purchasers | Patents Listed by Decade | Pending Patents | Claims | Mines | Map

In Idaho the hardrock mining industry has acquired the title to an estimated 203,242 acres of land previously owned by the public and rich in gold, silver, and other precious metals and minerals. Although a moratorium on new mining "patents" - conversion of public lands to private - has been in place since 1994, the government continues to grant pending requests. Since 2000, 15,600 acres of public lands across 12 western states have been converted to private ownership, for a price capped at $5 per acre in 1872. See who has gained title to lands since 1980, 1990, or 2000.

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.
