Does this mean we'll be producing 30000t cu pa or concentrate equivalent from 1.5mt of ore at $4t cost of refining.This seems to good to be true.Can someone please enlighten me as to where I've gone wrong.
Production modelling based on a throughput of 1.5 million tonnes per annum suggests that the Cyclone Deposit, with feed grades of 1.2% to 1.5% copper, could produce a 16-22% copper concentrate yielding 10,000 to 14,000 tonnes of copper metal annually. Similarly, the Chinook Deposit, with a feed grade of 1.5% copper, could generate a 16-22% copper concentrate, resulting in 15,000 to 16,000 tonnes of copper metal per year.
So 30,000t Cu x $8800pt usd=$260,000,000 less 1.5mtpa x$4pt refining..........na,I need some sleep
