TerraMS-12JUL-001 Wellgreen - Pt-Pd Minerals Deportment – LCT01 Tails INTRODUCTION The present document reports information concerning the deportment of Platinum- and Palladium-bearing particles encountered in one 1 st Cleaner Tail and one Scavenger Tail sample (Table 1). These tail samples were generated from Locked Cycle Test 1(LCT 01), performed March 14, 2012, to test ore mineralization originating from workings located in the East zone of the Wellgreen Copper-Nickel PGE deposit of Prophecy Platinum, located in Southwestern Yukon. The main scope of the present mineralogy examination was to determine the PGE mineral mode of occurrence and gangue associations, with a secondary objective of outlining the broad PGE mineral families observed. Table 1. Examined Tail Samples* Assays, % Assays g/ t Cu Ni S Fe Pt Pd Au Ni 1st Cleaner Tail (**) 0.13 0.48 7.48 18.5 1.02 0.61 0.05 Ni Scavenger Tail(**) 0.03 0.13 1.15 10.4 0.22 0.09 0.02 *: Analyses carried out at SGS geochemistry laboratories (**): combined cycles E, F, G Approximately 34.7% Platinum and 21.0% Palladium are deported to the Nickel 1 st Cleaner Tail of LCT1; whereas 40.7% of the Platinum and 16.9%, of the Palladium report to the Nickel Scavenger tail of LCT1. Thus, considerable amounts of these two elements are lost to these tailings streams. METHODOLOGY A group of five polished sections was prepared for each tail sample. The entire surface of each section was scanned to identify PGE-bearing minerals and associated gangue phases. The sections were scanned for PGE mineral occurrences using SEM-EDX. The SEM scans were performed using the ASPEX eXplorer Scanning Electron Microscope fitted with automatic stage movement and the Automatic Feature Analysis (AFA) software set to recognize precious metal grains. The SEM-EDX recognition software collected a series of physical parameters for each particle of interest, in particular the maximum width and length of PGE particles and the total area of each precious metal grain. In addition, standard ore microscopy scans and manual SEM-EDS scans were also performed on selected areas of some sections, and additional very fine grained particles might have been detected and measured. In these instances, a normalized width and length was collected for each grain. For irregularly shaped grains, a “best fit” width and length was attributed to calculate the area of the grains. In addition to PGE mineral grain dimensions, other information recorded includes the mode of occurrence of PGE particles, and associated minerals. Information for each identified PGE grain was reported in data tables. Codes for the different modes of occurrence of PGE-bearing particles occurring in metallurgical products are presented in Table 2, and illustrated in Figure 1. A succinct list of mineral abbreviations that might have been used is presented in Table 3. 2
