  Going for Gold – Gold extraction reagent that do not cost …

  We are developing gold extraction reagents that don’t cost the Earth, but allow you to open up low grade, uneconomic or stranded deposits. We are developing a range of leach reagents that are far less toxic than cyanide, safer to handle and have a lower environmental risk when compared with cyanide. We believe the potential reduction in ...
