Public Land & Resources Law Review

The Ninth Circuit Court of Appeals affirmed the District Court of Arizona’s decision to deny a proposed mining plan becuase the operations exceeded the boundaries of a valid mining claim. The issue the court addressed is whether a permanent occupancy of waste rock and tailings on land, absent the discovery of valuable minerals, is a reasonable use related to mining activities. The Ninth Circuit decision effectively prevented mining companies from amending the 1872 Mining Law on the administrative record. Motions for a rehearing and a rehearing en banc were denied.
