EnviroLeach Receives Independent Analysis by SGS on High-Grade Samples

Published

VANCOUVER, British Columbia, March 11, 2019 (GLOBE NEWSWIRE) -- EnviroLeach Technologies Inc. (the "Company "or "EnviroLeach"), (CSE:ETI) (OTCQB: EVLLF) (7N2: FSE) is pleased to report independent analytical results from SGS, a world leading inspection, verification, testing and certification company. The research work was commissioned by EnviroLeach as part of their enhanced third party, independent validation program.

The first series of leach tests were conducted on high-grade samples, including gravity concentrate tails and flotation concentrates. Tests on oxidized material generated from autoclaving and roasting achieved over 94% within 2 hours. The results, using the EnviroLeach formulas, indicate that gold recoveries of over 85% were achieved on the table tails within 24 hours and over 90% recoveries from Flotation Concentrate within 24 hours. The tests were performed using the EnviroLeach based formulas with no sample related formula optimization. A summary of the results is presented below.

Cal Head(g/t Au) Assayed (g/t Au) Residue (g/t Au) Recoveries (%)
Sample 1 hr 3 hr 6 hr 24 hr
Table Tails 4,397 4,600 655 18.4 41.8 73.0 85.1
Float Conc 105 116 9.85 78.1 80.4 86.0 90.7

This second set of tests show extremely fast leaching behaviour on autoclaved and roasted samples with over 94% recoveries within 2 hours of leaching. No sample related formula optimization was performed. A summary of the results is presented below.

Cal Head (g/t Au) Assayed (g/t Au) Residue (g/t Au) Recoveries (%)
Sample 10 min 20 min 30 min 60 min 90 min 120 min
Autoclaved 31.2 28.5 1.21 85.8 88.6 93.4 95.0 96.2 96.1
Roasted 43.6 41.5 2.46 87.6 88.4 92.8 91.6 93.7 94.4

Ish Grewal, M.A.Sc., P.Eng. and Executive Vice President of EnviroLeach, states; "I am very pleased with the recent results from SGS. These positive, impartial test results are similar to hundreds of previous tests performed by our Company and independent metallurgical labs across North America. These test results also highlight the accelerated leach kinetics using EnviroLeach formulas on both the autoclave and roasted samples."
