(TSXV:GRDM)(OTC:MSMGF) (“Grid” or “the Company”) is pleased to announce the successful results of its bench scale metallurgical testwork program for its Mayville Deposit located in southeastern Manitoba, Canada. The program was designed to demonstrate copper and nickel separation from a bulk concentrate in order to produce quality nickel and copper concentrates. The latest testwork achieved successful nickel copper separation and significantly higher nickel recovery than in previous work. (nickel recovery was over 65%, vs 45% maximum recovery used in the Project’s 2014 PEA - an increase of 44%). The testwork was completed by XPS Expert Process Solutions, a Glencore Company, which is a Sudbury-based technical consultancy and testing firm with extensive experience in flowsheet development and nickel-copper cobalt ores.Summary of Latest Metallurgical Results Open cycle flotation testing on a new composite sample produced a bulk concentrate followed by separation into:A nickel concentrate grading 10.7% nickel with 65.1% nickel recovery. A copper concentrate grading 30.0% with 82.1% copper recovery. Both concentrates were deemed to exceed the quality requirements to be saleable to smelters. Cobalt reported to the nickel concentrate with a recovery of 62.5% and a grade of 0.66%. Platinum group metals (PGM ) and silver recovered to both concentrates also may provide potential added valueClosed circuit simulation completed by XPS concluded that further improvements in nickel recovery and concentrate grade and copper recovery may be achievable. Modelling suggested nickel recovery of 68% at 11% concentrate grade and copper recovery of 90% at a 25% concentrate grade may be achieved based on the composite sample tested. Grid President & CEO Robin Dunbar commented, “The latest metallurgical testwork provides significant new encouragement for the potential project economics of the Mayville Deposit, as these results significantly surpass prior metallurgical results achieved and incorporated in the 2014 PEA.
