Copper Quotation averaged over the quotational period. Example) For a concentrate with a copper content of 30 % the payable copper value is: 30% x % x 7,000 USD/tCu = 2,030 USD/DMT Example) For a concentrate with a copper content of 24% the payable copper value is 24% – 1%unit = 23% 23/24 x 100 = % payment:
