billyb, the 35% operating margin is based on processing our own tailings. Worked out yesterday that equates to a cost per tonne of copper produced of roughly $3700 a tonne.
The new deal will mean we're buying copper concentrate from the JV, so we'll have extra cost there. But its not quite as straightforward as assuming our cost will increase and we'll have a lower margin because we'll be buying the material. First, we have a majority profit share on the copper concentrate sold by the JV, so we'll also make some profit on what we buy to process at sable. Second, the copper concentrate we buy should reduce our cost of $3,700 we currently have at sable, as it'll remove the need to concentrate the material at sable and thereby reduce the current cost. But then we'll also have transportation costs to factor in.
