US company Group 11 Technologies has announced positive results from its first test in the process to develop In-situ Recovery of gold with the use of environmentally friendly solutions.
Samples were acquired from previously drilled core from the Rattlesnake Hills Gold Project, in the U.S. state of Wyoming which is under option from GFG Resources to Group 11, according to a statement.
“The gold recovery tests from uncrushed half-core samples demon-strated recoveries ranging from 15.9% to 77.5%, averaging 48.2% using a non-cyanide solution. Bottle roll testing of crushed and ground material returned gold recoveries ranging from 38.3% to 89.5%, averaging 61.4% using a non-cyanide solution. Group 11 is working to develop and prove the process for ISR of gold and other metals,” the Dallas-based firm said.
