A massive porphyry style deposit located at high altitude in West Papua. Average grade of the deposit is 0.5 g/t Au and 0.8% Cu. The deposit has a UCS of 200MPa and is highly fractured; country rock is similar in nature. The deposit has a large foot print area 500m by 500m and is located from 300m to 900m from ground surface. Assume ore recovery of 95% and dilution 10% during production operation. Please do the followings in not more than three A4 pages (provide citation and references):
(1) Based on the most probable optimized mining method determined in Assignment 1 and the feedback from the lecturer, do market investigation of commodity prices and mining cost (2 marks).
(2) Compute the ore reserve and total profit of the project (3 marks).
(3) Estimate the Life of Mine (2 marks); and
(4) Assuming the deposit is a green field, briefly outline a short-, medium- and long-term plan of the project (including mine development, mining operation and mine closure) (3 marks).
