Mantos Blancos is a small copper producer by Chilean standards and it s reserves are only a fraction of what is stated. As usual, the non mining types confuse measured, indicated and inferred resources which are totally different things but it is still difficult to see where such a ridiculous figure came from. However it has been sold to a private company and little more is likely to be published so the whole thing is now a waste of time. I do wish non miners would leave the minind companies to those with a little mining knowledge. Egoli ( talk) 01:03, 4 October 2016 (UTC) reply
