Dundee Sustainable Technologies Inc. announced the successful piloting results and a 96.1% gold recovery on high grade concentrate. In May of 2014, DST received two concentrate samples totalling 1,300 kilograms from a privately held gold mining company. The samples were processed at DST's Thetford Mines facility using its patented cyanide and mercury free gold extraction process.

A two (2) hour contact time, using DST's chlorination process, was necessary to achieve a gold extraction yield of 96.1% in the reactor, despite the presence of substantial base metals in the concentrate. The gold was recovered on silica with an efficiency of 99%. The gold loaded silica was melted to produce the gold bullion.
