Copper price used (US$ 6,000 /t Cu) is net of TC-RCs. Net revenue calculation: (Copper Price -TC-RCs) - marginal operating cost - marginal capital cost. Marginal operating cost includes ball mill power, grinding media and liners. Marginal capital cost is the installed ball mill cost divided by a nominal payback period of 5 years.
