Originally published in 1987, John D. Leshy presents this scholarly study of the 1872 Mining Law as a legal treatise and history of mining in the West from the point of view of mineral exploration and production. This mining law governed the United States mining practice yet had never been changed. The Mining Law attempts to highlight the role of policy and government as well as the more obscure elements of the law which complicated mining practice in the eighties. This title will be of interest to students of Environmental Studies and policy makers.
