The company owns the patented BACOX bioleaching technology. This technology is used for the processing of toxic, arsenic-laden mine tailings. An added benefit of bioleaching, in addition to stabilizing arsenic and capturing heavy metals, is that it oxidizes sulphides in mine tailings, thereby eliminating a major source of acid mine drainage.
