The following capital investment was required for a 60,000 TPD operation: Cost Items Property acquisition Mine development and mine plant Mill, water supply, and tailings disposal area Property improvements 75 124 42 Based on the development of similar properties, it can be assumed that the mine, mill, and property improvements can be scaled using the "sixth-tenths" factor. The property acquisition cost remains constant regardless of the operating tonnage. The new ore body will sustain any size operation up to 75,000 TPD a) Calculate and tabulate the total capital investment required for the entire property (the sum of the acquisition, mine, mill, and property improvements) for operating rates of 55,000, 60,000 and 65,000 TPD. Convert to S/TPD capital investment for the entire property at each operating rate and include in the table It is not the total tonnage treated, but the tons of copper produced and available for sale that is the determining factor in the profitability of an operation. Using the 60,000 TPD operating rate and assuming a 365 days per year operation, a copper content of 0.51%, and a copper recovery of 86.3%, calculate the total tonnage of copper produced annually and the total capital investment in S/annual ton of copper produced. b)
