Comments on the commodity information

  • PLATINUM-GROUP ELEMENTS. IF PUBLISHED ANALYSES OF SAMPLES OF ORE FROM THE STRATHCONA MINE (PYE, NALDRETT AND GIBLIN, RF5) ARE REPRESENTATIVE, THE APPROXIMATE PROPORTIONS OF PGE'S AND AU IN EXTRACTED ORE FROM THAT MINE WOULD BE AS FOLLOWS: PT 50%, PD 40%, OS+RU+RH 5%, AU 5%. BASED ON THE SAME DATA, AND ASSUMING AN AVERAGE NI GRADE OF 1.3% THE AVERAGE MINED (PGE + AU) GRADE WOULD BE ABOUT 0.4 G/TONNE. NO INFORMATION IS AVAILABLE ON RECOVERIES OF PGE AND AU.
