In-situ mining is the removal of the valuable components of a mineral deposit without physical extraction of the rock (Bates and Jackson, 1987). In-situ leaching is a type of in-situ mining in which metals or minerals are leached from rocks by aqueous solutions, a hydrometallurgical process (American Geological Institute, 1997). In-situ leaching has been successfully used to extract uranium from permeable sandstones in Texas, Wyoming, and Nebraska, and in-situ leaching of copper has been successfully demonstrated in underground copper mines in Arizona, where prior mining has created sufficient permeability for leaching solutions (lixiviants) to contact ore minerals (Bartlett, 1992, 1998; Coyne and Hiskey, 1989; Schlitt and Hiskey, 1981; Schlitt and Shock, 1979). As used in this report the term in-situ mining includes variations that involve some physical extraction
