Just a quick calculation to put 12 mill in percepective. 3k tons of coper which is 3month or a quarter of a year of the scheduled production. With 3000 tons of coper produced at $7k equals to 21 mill after 1/3 cost it leaves account with 14 mill. So to make a deal with a downstream producer for a longer term on mutually benefit terms would be best and quite possible scenarios.
