Generation Mining Reports Significant Increase in PGM, Copper Recovery

TORONTO, Aug. 20, 2020 (GLOBE NEWSWIRE) -- Generation Mining Limited (TSX: GENM) (OTCQB: GENMF) (“Gen Mining” or the “Company”) is pleased to report an update to its work program on the Marathon Palladium project in northwestern Ontario (the “Marathon Project”). The Company has successfully completed bench-scale metallurgical test work, resulting in a favourable and significant increase to projected Platinum Group Metals (“PGM”) and Copper (“Cu”) recovery. Expected increases in metal recovery will be included in the feasibility study work.

Metallurgical testing commenced at SGS Canada Inc. in Lakefield, Ontario in June 2020 for the Feasibility Study that is currently underway. The 2020 Phase 1 Metallurgical Testing program is being overseen by Steve Haggarty, P.Eng., of Haggarty Technical Services (“HTS”) and Ausenco Engineering Canada Inc. (“Ausenco”) (who will be the Qualified Person for the upcoming metallurgical and processing sections of the Feasibility Study Technical Report). The Phase 1 Metallurgical Testing program achieved the following results:

2020 Phase 1 Metallurgical Recovery 1 (as determined by SGS-Lakefield 2020 Met Testing Program - Phase 1)			PEA2 Metallurgical Recovery		Variance + positive - negative
Palladium	86.9%		82.9%		+4.0%
Copper	93.0%		90.0%3		+3.0%
Platinum	84.2%		74.5%		+9.7%
Gold	72.4%		73.2%		-0.8%
Silver	Not evaluated in this program		71.5%		n/a
1 Recovery calculations are based on the established head grade of composite samples ranging in Cu, Pd, Pt, and Au head grade and involving multiple benchscale flotation tests.  2 Preliminary Economic Assessment (“PEA”) of the Company titled “Amended Technical Report, Updated Mineral Resource Estimate and Preliminary Economic Assessment of the Marathon Deposit, Thunder Bay Mining District Northwestern Ontario Canada” dated July 6, 2020 (effective date of January 6, 2020); 3 The estimated recovery of Cu is noted per the PEA for years 6-14

The goal for Phase 1 Metallurgical Testing was to improve overall metal recovery relative to the PEA and validate changes considered to the process flowsheet relative to previous concepts considered for the project. The 2020 Phase 1 Metallurgical Testing program focused on three main aspects:
