TORONTO, Oct. 22, 2020 (GLOBE NEWSWIRE) -- Generation Mining Limited (TSX: GENM) (OTCQB: GENMF) (“Gen Mining” or the “Company”) is pleased to provide an update on the continued progress of the Feasibility Study currently underway for the Marathon Palladium project in northwestern Ontario (the “Marathon Project”).

The Company previously reported on the Phase 1 bench-scale metallurgical testing program (news release dated August 20, 2020) that determined the recovery to be used for the Feasibility Study and the expected recoveries for the Project going forward. The Phase 1 Metallurgical Testing program achieved the following results:

In September 2020, the Company progressed to a Phase 2 metallurgical testing program, again at SGS Canada Inc. in Lakefield, Ontario. The Phase 2 Metallurgical Testing program is being overseen by Steve Haggarty, P.Eng., of Haggarty Technical Services (“HTS”) and Ausenco Engineering Canada Inc. (“Ausenco”) (acting as the Qualified Person for the upcoming metallurgical and processing sections of the Feasibility Study Technical Report). The goal of this program is to further define (i) the performance of the cleaning and scavenger flotation circuits, (ii) the optimal grind size in the regrind circuit and (iii) the overall validation of the circuit performance with a mini-pilot plant. The first two tasks have been completed. The initial locked cycle testing and a pilot plant program commenced mid-October and will be completed during November 2020.
