Hardrock Mining: Information on State Royalties and the Number of Abandoned Mine Sites and Hazards

The General Mining Act of 1872 helped open the West by allowing individuals to obtain exclusive rights to mine billions of dollars worth of gold, silver, and other hardrock (locatable) minerals from federal lands without having to pay a federal royalty. However, western states charge royalties so that they share in the proceeds from the hardrock minerals extracted from their lands. For years, some mining operators abandoned land used in their mining operations, creating environmental and physical safety hazards. To curb further growth in the number of abandoned hardrock mines on federal lands, in 1981, the Department of the Interior's Bureau of Land Management (BLM) began requiring mining operators to reclaim BLM land disturbed by these operations.
