RE: Last NR - mill test 5 -7 % copper.As best as I understand it, the mill testing of the 5 -7 % copper, is a costing exercise with the end game being distribution to the North American market not the direct shipping overseas.
5% copper short ton is 100 lbs. At $3.50 lb we are looking at $350 in copper per ton. Dealing with local mills should leave room for profit.
