Prophecy Platinum Reports 1.04 Million Oz PGM+Gold Indicated And 10.97 Million Oz PGM+Gold Inferred For The Wellgreen Project, Yukon Territory, Canada

Vancouver, British Columbia, July 14, 2011: Prophecy Platinum Corp. ("Prophecy Platinum" or the “Company”) (TSX-V: NKL, US-PINK: PNIKD, Frankfurt: P94P) is pleased to announce the receipt  of an independent National Instrument (NI) 43-101 compliant report and mineral resource estimate for its Wellgreen PGE-Ni-Cu property located in the Yukon Territory, Canada.  The report is authored by Todd McCracken, P. Geo. of Wardrop Engineering Inc., a Tetra Tech Company, who is an independent Qualified Person under NI 43-101. 
The independent study incorporated drill data from 701 diamond drill holes (182 surface and 519 underground) totalling over 53,222 metres. Using a 0.4% NiEq (nickel equivalent) cut-off grade, the Wellgreen deposit now contains a total inferred resource of 289.2 million tonnes at an average grade of 0.53 g/t platinum, 0.42 g/t palladium, 0.23 g/t gold (1.18g/t PGM+Gold), 0.38% nickel, and 0.35% copper. Separately, the deposit also contains an indicated resource of 14.3 million tonnes at an average grade of 0.99 g/t platinum, 0.74 g/t palladium, 0.52 g/t gold (2.25 g/t PGM+Gold), 0.69% nickel, and 0.69% copper. The resource includes both the East Zone and the West Zone of the Wellgreen project, which are tabulated in Table 1 showing respective metal grades which are also expressed as nickel equivalent (NiEq) values:

Several parameters were used in calculating the reported resource:
  • NiEq =((Ni%*$Ni*22.0462)+(Cu%*$Cu*22.0462)+(Co%*$Co*22.0462)+(Au grade*$Au*0.029167)+(Pt grade*$Pt*0.029167)+(Pd grade*$Pd*0.029167))/($Ni*22.0462);
  • Long term average metal prices in $USD of $9.52/lb nickel (NiEq prices based on this amount), $2.96/lb copper, $15.78/lb cobalt, $1085/troy ounce gold, $1776/troy ounce platinum, $689/troy ounce palladium;
  • Visual comparison of colour-coded block model grades with composite grades on section and plan;
  • Comparison of the global mean block grades for ordinary kriging (OK), inverse distance squared (ID2), nearest neighbour (NN) and composites;
  • Swath Plots comparing NN estimates and OK estimates;
  • 701 drillhole database used compiling over 12,000 assays.
