VANCOUVER, BC / ACCESSWIRE / November 27, 2019 / EnviroLeach Technologies Inc. ("EnviroLeach"), (CSE:ETI)(OTCQB:EVLLF)(FSE:7N2), a global leader in innovative and eco-friendly precious metal extraction from mineral ores and E-Waste, announces the preliminary results of a bulk test conducted by Golden Predator Mining Corp. using EnviroLeach's patent-pending solution on sulfide-based gravity concentrates from Golden Predator's 3 Aces Project.

On November 12, 2019 Golden Predator announced the results from a successful pilot test on their gold sulfide concentrate at the EnviroLeach E-Waste plant. Two concentrate samples weighing 55.9 kg and 30.4 kg were processed at the plant using EnviroLeach's water-based process. Following dissolution, conventional electrowinning was used to extract the gold from solution which resulted in gold recoveries of 96.5% after 6 hours and 96.7% after 29 hours. During this test two gold buttons with a combined weight of 169 grams (5.5 troy ounces) were produced. A second test program was run at Golden Predator's plant, located in Watson Lake, Yukon. Once again, the EnviroLeach process proved successful at processing Golden Predator's concentrate. A 121 kg sample was processed with measured recoveries of 96.2% gold, resulting in 255 grams (8.2 troy ounces) of gold extracted from solution by electrowinning.

Due to these initial positive results, the companies have agreed to increase the scale of testing with an additional five-tonne bulk sample, to be processed using EnviroLeach's solution at Golden Predator's plant during the 2020 operating season.

Duane Nelson, President and Chief Executive Officer of EnviroLeach commented: "I am very pleased to announce this working relationship with Golden Predator. The gold recovery from Golden Predator's arsenopyrite concentrate confirms the ability of our new eco-friendly formula to extract gold into solution from sulfide ores and recover it using conventional technologies. The EnviroLeach process now provides a cost-effective solution for the extraction of gold from historically problematic materials such as arsenopyrite."
