Q.1 The following Grade-Tonnage table represents a summary of a Copper deposit that is proposed to be mined as an open pit. Mine Design Parameters Grade category Tonnage (%) M tons 1 - Concentrated Copper price (P) = $ 1425/ton 0.00 2.00 22.50 2- Sales cost (s) = $ 25/ton 2.00 4.00 18.90 3 - Milling cost (c) = $ 70/ton 4.00 6.00 17.00 4 - Recovery (y)= 75% 6.00 8.00 8.00 5-Mining cost (m) = $ 5/ton 10.00 4.10 10.00 12.00 2.10 6- Fixed cost (Fa) = S 7 Myear 12.00 14.00 4.10 7 - Capital cost (CC)= $ 196 M 14.00 16.00 3.10 8 - Mining capacity (Qm) = unlimited 16.00 18.00 2.50 9- Milling capacity (Qc) = 1.4 M tons 18.00 20.00 2.70 Total 85.00 10 - Discount rate (d) = 12% 8.00 Complete the year-by-year schedule (OSR/Q.m/Q.r/Cash Flow/ Mine Life/NPV) according to second scenario of heuristic cutoff grade optimization where; A. Assume to have a minimum profit of $ 8/ton in the first coming 4 years, B. Assume that the depreciation will extend for the first 10 years of the operation life.
