Prophecy Platinum Corporation announced the results of its preliminary metallurgical tests for its Wellgreen Ni, Cu and PGE project located in the southwest of Canada's Yukon Territory.

This Phase I of an extensive metallurgical program focuses on producing a bulk Ni-Cu-PGE-Au concentrate from disseminated sulphide, ultramafic mineralized rocks that comprise the majority of Wellgreen's National Instrument 43-101 resource:

To date, a total of 41 rougher and cleaner tests and 4 locked cycle flotation tests have been conducted and completed at SGS Laboratories in Vancouver, British Columbia. Results indicate that a bulk concentrate of 5.6% nickel, 6.0% copper, 3.5 gram per tonne platinum, 6.3 gram per tonne palladium and 0.5 gram per tonne gold can be produced.

A150 kilogram composite blend of the prevalent host mineralized rocks was crushed to a 10 mesh size and used as the sample for testing. A calculated head feed grade of 0.45% nickel, 0.35% copper, 0.42 gram per tonne platinum and 0.46 gram per tonne palladium was tested. Conventional flotation conditions were used to produce a concentrate with emphasis on base metal recoveries from locked cycle testing.

While this preliminary phase focused on metal recovery from Wellgreen's mineralization of typical representative grade, an additional test was conducted using material with a higher calculated head feed grade of 0.83% nickel, 0.55% copper, 0.57 gram per tonne platinum, 0.57 gram per tonne palladium and 0.08 gram per tonne Au. LCT-4 produced a concentrate containing 8.2% nickel, 6.5% copper, 2.9 gram per tonne platinum, 5.6 gram per tonne palladium and 0.6 gram per tonne gold. These results represent recoveries of 73% nickel, 88% copper, 38% platinum, 73% palladium and 62% gold.

The 41 batch tests were designed to test different flowsheet and reagent combinations. Conditions for the reported test LCT-3 include Xanthate, CMC, guar gum and CuSO4. Test conditions for LCT-4 utilized the same reagents as LCT-3 except for the exclusion of CuSO4. LCT-3 and LCT-4 demonstrate that metals can be recovered from varied Wellgreen mineralization through substantially identical flowsheets and common reagents.

Mr John Lee chairman of Prophecy said that "We are delighted with these preliminary results. The follow-up met studies along with our infill drilling, expansion drilling, and preliminary economic studies in 2012 will continue to de risk our 100% owned Wellgreen project and advance this highly unique asset towards feasibility."
