Prophecy Platinum Corporation – Wellgreen Property – Project 50149-001 analysis. Mineral modal analysis of the LCT-1 products illustrating the mineral distributions is presented in Table 28. Modal analysis and pentlandite, pyrrhotite, chalcopyrite, chlorite/serpentine, talc and Fe Ox associations results are presented in Appendix G.

PGE minerals predominately occur as liberated particles in the Ni 1 st cleaner tail. In contrast, only minor amounts of liberated grains (all of them sperrylite) are deported to the Ni scavenger tail, whereas the bulk of PGE minerals reports to this sample as inclusions or intergrown with gangue minerals. Most of the non-liberated PGE minerals occurring in the Ni 1 st Cleaner Tail are intergrown with pyrrhotite and only minor amounts are associated with magnetite or silicate gangue. In the Nickel scavenger tail, two-thirds of the PGE minerals are also intergrown with sulphide (chiefly pyrrhotite), yet approximately 21% are also associated with silicate gangue. It is note worthy that almost half of the Pt losses (mineral sperrylite) is as small liberated particles. PGE mineralogy results are presented in Appendix G. 7. Concentrate Analysis The potential for the deposit is known to contain various impurity elements which may result in penalties or bonus payments at the smelter. In order to complete the study, full multi-element analysis was conducted on concentrates produced from each locked cycle test. 7e and Co ICP-Scan for the LCT-1 products were also conducted. Tables 29-32 list the results. The concentration of various elements in locked cycle test concentrates from master composite feed material are presented, mainly as ICP results, in Appendix B. SGS Minerals Services 52
Prophecy Platinum Corporation – Wellgreen Property – Project 50149-001 Generally, there were no significant differences in the grades of minor elements in the concentrates. Deleterious elements do not appear to be present in sufficient quantities to create marketing issues with these concentrates.
