EnviroMetal Technologies Inc. announced a process breakthrough which potentially reduces reagent consumption and operating costs while maintaining high levels of gold recovery. This lab scale discovery is a result of the ongoing development of EnviroMetal's proprietary non-cyanide leaching agent and gold recovery process (the "EnviroMetal Process"). Lab and pilot scale testing of the EnviroMetal Process have repeatedly demonstrated its effectiveness for extracting gold from high grade gold ores and concentrates at recovery levels and process costs similar or superior to those of a conventional cyanide leach process.

EnviroMetal's latest process breakthrough involves using a revised lixiviant formulation requiring up to 80% less primary leach reagent in combination with reduced agitation. By lowering the concentration of reagents in the leaching agent, EnviroMetal was able to correspondingly lower the initial cost of the lixiviant and operating costs related to reagent losses. These cost reductions expand processing applications to include lower grade gold ores and concentrates.

The EnviroMetal Process deploys a patented lixiviant within a proprietary, closed-loop processing circuit combining both proprietary equipment and readily available ancillary equipment that can be locally sourced in most jurisdictions. The EnviroMetal Process incorporates straightforward steps to produce precious metal doré as a final product without the need for additional, post-leach downstream processing and reagent destruction systems typically associated with cyanidation processes. EnviroMetal's technology is highly scalable and can be installed as a bolt-on solution for mining operations producing gravity or flotation gold concentrates, or as a standalone alternative for whole ore processing.
