Further Studies Confirm Superior Results of EnviroLeach Compared to Cyanide
VANCOUVER, May 30, 2019 - EnviroLeach Technologies Inc. (the “Company “or “EnviroLeach”), (CSE: ETI) (OTCQB: EVLLF) (7N2: FSE) is pleased to report that studies comparing EnviroLeach to that of cyanide on two separate samples of high grade mineral ore verified that EnviroLeach outperformed cyanide on both overall recoveries and leach kinetics. The research work was done by EnviroLeach and SGS in Burnaby.
The 24-hour leach tests were performed as part of a continued strategic collaboration between the Company and several gold producers. The tests were conducted on high-grade ore and flotation concentrates using the EnviroLeach formula compared to a high-grade 5 g/l cyanide solution. SGS was contracted to conduct the cyanide leach tests for the comparison.
The tests on the high-grade ore sample, with an assayed gold head grade of 675 g/t, showed the most favorable results with the EnviroLeach formula attaining gold recoveries of over 99% in under 6 hours with cyanide attaining recoveries of 94% in 24 hours. The results are presented in graph 1 and the following table:

Flotation concentrate, with an assayed gold head grade of 55.1 g/t, showed high gold recoveries of over 90% by EnviroLeach in 6 hours. Cyanide provided similar recoveries in 30 hours. The results are presented in graph 2 and the following table:
