I should have added regarding problems: If we do not preprocess the ore ( preprocessing to minimize volume for piping ) but pipe it raw then I expect no pollution problems. If we preprocess then there could be some difficulties with spillage but spills are rare and again the clean up should be straight forward. Preprocessing would allow us to put back some of the matter back into the hole it came from. Again saving costs and avoiding problems of surface storage. All in all I am pleased with the plans of the company. If only native issues would stay away and the governments would get off their butts and contribute more substantively and more quickly, we would be sailing along nicely. Cheers.
