Mining claims in New Mexico

Jump to: Claim Owners | Patents | Mines | Map

Location:   

The hardrock mining industry owns gold, silver, and other precious metals and minerals beneath an estimated 170,231 acres of U.S. public land in New Mexico, 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.
