EnviroMetal Reports High Gold Recoveries in Leach Tests for the McAdams Creek Mine

VANCOUVER, BC / ACCESSWIRE / November 29, 2021 / EnviroMetal Technologies Inc. („EnviroMetal“ or the „Company“), (CSE:ETI)(OTCQX:EVLLF)(FSE:7N2) is pleased to provide the following press release on the results of test work performed for Global Mineral Research Ltd. („GMR“) on mineralized material from the historic McAdams Creek Mine in California, USA.

The studies confirmed that the EnviroLeach formula achieved high gold recoveries of over 90% in less than 24 hours versus 82% recoveries from similar 36 hour cyanide-based tests.

Two samples from the McAdams Creek Mine were received at the EnviroMetal laboratory in Burnaby, BC., and were processed separately using EnviroMetal’s lixiviant/formula. After 24 hours of processing the calculated gold recoveries for both samples were approximately 90% as outlined in Table 1 below.

A comparative 36-hour scoping level cyanide bottle roll test was also performed on an approximately 1 kg composite sample of gravity tailings from the McAdams Creek Mine. For the bottle roll test, the cyanide dosage was maintained at between 2.0 to 3.0 grams per liter of sodium cyanide, and the tailings material was ground to a targeted 74 microns. Gold recoveries using sodium cyanide as the lixiviant achieved only 82% in 36 hours.

Tas Morfopoulous, CEO of Global Mineral Research stated: „We are extremely pleased with the gold recoveries demonstrated using EnviroMetal’s water-based formula. The gold recoveries in tests using the EnviroMetal solution were dramatically superior to the gold recoveries in similar tests using cyanide. We work on mining projects globally with many projects in environmentally sensitive jurisdictions. The EnviroMetal process has the potential to unlock the value of several „environmentally-dormant“ gold projects. We will continue to test the capabilities of EnviroMetal’s technology on several projects as a prospective alternative to cyanidation and concentrate smelting.“
