Willy, You are correct on the first paragraph. My concern comes that either the dollar today and the price of copper today both affect us, or the dollar at production and the price of copper at production affect us. It can not be the copper price doesn't affect us it affects the producer when in production, so eliminate the negative on us now but promote that every cent drop in currency rate increases our NPV now by 75mil now. If that makes any sense to you.
