    The program and independent review of Batch 1 and 2016 Bulk Sample, medium to high sulphide type mineralized materials encompassed gravity, flotation and magnetic separation test work. Bench tests successfully produced saleable up to 30% Cu and between 37 and 62 g/t PGMs concentrates with 80% Cu recovery. An independent review of the mineralogy of the deposit estimates the pyrrhotite (iron sulphide) to pentlandite (Ni sulphide) ratio is in the range of 35:1 in the massive and semi-massive sulphide zones of the deposit, with the Ni deportment to pentlandite to be about 71% envisioning the creation of a potentially payable 10% Ni bearing concentrate with 51% Ni recovery.

    In general, the bench testing of the Batch 1 and 2016 samples, produced high-grade copper and variable grade Ni/Cu concentrates ranging on a grade – recovery curve from 5 to 20% Cu-Ni with recoveries of up to 98% Cu, 61% Ni and 35-75% PGMs. It was concluded that there is potential to significantly improve these results with additional testing using optimized conditions based upon our improved understanding of the Cu, Ni and PGM’s mineral deportment.

    Bench testing of the Batch 2 sample, which was obtained from the low-sulphide PGM rich type mineralized material successfully created potentially payable precious metal concentrates in which the highest PGM grade achieved was 92.1 g/t Pd plus 96.5 g/t Pt (totalling 189 g/t) and recoveries of up to 75% Pd and 55% Pt when gravity separation was included in the flotation flowsheet. Additional tests and investigations of the PGM mineralogy of the deposit are expected to improve these results.
