Calculate the FGO cut-off grade (in g/t) for an Ore Reserve with the following data. Show the formula used and all calculations: a) Total tonnes mined over LOM = 151Mt b) Tonnes treated through processing plant over LOM = 29Mt c) Metallurgical recovery = 85% d) Metal produced over LOM= 1,686,795 ounces e) Metal price = R1900/oz f) Exchange rate = US$1 = R18.00 g) Processing cost = R285/t treated h) Admin and other costs = R12.20/t treated i) Ore rehandle cost = R18.30/t treated i) Mining fixed cost = R25.00/t treated k) Ore mining cost = R56.21/t mined 1) Waste mining cost = R51.42/t mined m) Closure cost = R4.55/t mined n) Non-mining stay in business capital cost = R15/t treated o) MCF = 95% p) Selling costs over LOM = R13Bn Tip: Note the units (R/t mined; R/t treated; Ounces; LOM; etc.) [30] Calculate the FGO cut-off grade (in g/t) for an Ore Reserve with the following data.
