re: Ann: New Gold Extraction Process for Tunk...
See the follwoing links: http://en.wikipedia.org/wiki/In-situ_leach => "In-situ leaching has not been used on a commercial scale for gold mining. A three-year pilot program was undertaken in the 1970s to in-situ leach gold ore at the Ajax mine in the Cripple Creek district in the US, using a chloride and iodide solution. After obtaining poor results, perhaps because of the complex telluride ore, the test was halted.[7]"
