Instead of only going after gold nuggets and flakes, we examined the subject of mineral extraction at a microscopic level. With our proprietary, proven and cost effective technology we are able to extract up to 90% (or more) of the gold present in mine tailings. Developing the technology and proving it could be done was only the first step.
