Prophecy Announces Highly Encouraging Rhodium, Ruthenium, Osmium & Iridium Assays from WS11-188 of Wellgreen Project
VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 25, 2012) - Prophecy Platinum Corp. ("Prophecy" or the "Company") (TSX VENTURE:NKL)(OTCQX:PNIKF)(FRANKFURT:P94P) is pleased to provide results of full spectrum 6E (Pt, Pd, Rh, Ru, Os &, Ir) analysis of PGEs on the first batch of samples from the Company's 100% owned Wellgreen PGM-Ni-Cu project, located in the Yukon Territory, Canada.
The Company enlisted Activation Laboratories (Actlabs), based out of Ancaster, Ontario to conduct a full spectrum 6E analysis of samples taken from the 2011 drill hole WS11-188. Adding Rh, Ru, Os and Ir to Pt and Pd increased the total PGE content (6E) by an average of 28%, based on a population of 90 samples, most of which are from disseminated sulphide-type mineralization.
Assay results with 6E exceeding 0.50 ppm (0.5 g/t) (excluding copper and gold assays) are tabulated below. Assay results from the entire batch of 90 samples can be downloaded at www.prophecyplat.com.

6E assay results are still pending for an additional 260 samples taken from WS11-188, including samples from sections that showed higher Pt and Pd grades in the above table.
In 2007, 800 chip channel samples taken at 2 metre intervals along the underground workings were assayed for platinum and palladium at the ALS Chemex Lab in Vancouver, B.C. Of these, 174 samples where platinum or palladium grades exceeded 1 g/t were assayed for Rh, Ru, Os and Ir. The 2007 sampling program was overseen by Rory Calhoun, P. Geo., now a consultant of Prophecy. Subsequent 6E assay results were announced in a Prophecy Coal's press release on November 3, 2010. For comparison, assay results where Rhodium exceeded 500 ppb (0.5 g/t) are tabulated below. Concentrations of Rh, Ru, Os and Ir were present in all of the follow-up samples, and the total PGE content (6E) increased by an average of 114.8% over prior assay results which only included Pt and Pd.

Prophecy Platinum's Chairman, John Lee, notes: "The assay results suggest that 6E (Pt, Pd, Rh, Ru, Os & Ir) PGE composite grades increase by an average of 28% (disseminated sulphide) to 114.8% (massive sulphide) over grades previously announced when only platinum and palladium were considered. Today's results could potentially translate into a significant rare PGE resource addition to an already impressive platinum and palladium resource base(i) at Wellgreen."

Quality Control and Quality Assurance
Prophecy Platinum executes a quality control program to ensure best practice in sampling and analysis. Samples are cut and split for assay with the remaining sample retained for reference. Blanks, Standard Reference Material (SRM), and duplicates were inserted into the sample stream every 20th sample. A duplicate sample is taken every 20th sample of core. The selected sample is sawn in half and then sawn in half again. The quartered core is then placed into two different sample bags with different sample numbers and sealed. The SRM material comes from Natural Resources Canada and Analytical Solutions Limited. These were inserted into the sample stream immediately after the second duplicate. The SRMs used are WMS-1, WPR-1 and WGB-1. Sample Blanks are obtained from two sources: granodiorite from a local quarry and garden marble from hardware stores in Whitehorse, Yukon. A Blank sample is inserted into the sample stream after the SRM. Assayed samples are transported in sealed and secured bags for preparation at ALS Chemex Prep Lab located in Whitehorse, Yukon. Pulverized (pulp) samples are shipped for analysis to ALS Chemex Assay Laboratory in Vancouver, B.C. ALS Chemex is an ISO/IEC 17025:2005 accredited laboratory and registered under ISO 9001:2000.
Full spectrum PGE analysis was completed by Activation Laboratories (Actlabs) based out of Ancaster, Ontario. Samples from 5 - 50 g in size are fire assayed using a nickel sulphide (NiS) fire assay procedure. With this procedure, the Ni, Cu, Cr and S content of the sample is predetermined and each sample is fluxed separately with the flux adjusted for sample composition. The flux contains high-purity Ni produced by the carbonyl process, borax, sodium carbonate, silica and high purity sulphur. The sample is fused at 1100 degrees C in fireclay crucibles and allowed to cool in the crucible. The nickel sulphide button at the base of the crucible is dissolved in concentrated HCl and the resulting residue which contains all the PGE and Au are collected on a filter paper. This residue undergoes 2 irradiations and 3 separate counts to measure all the PGE and Au.
Quality assurance and quality control are monitored using scatterplots, Thompson-Howarth plots and statistical analysis to ensure duplicates, blanks and standard data are reliable and indicate robustness of overall results. ALS Chemex quality-assurance procedures are also included in this process.
