There is no easy route to getting gold out of a polymetallic. They always talk as though it is a net benefit, which it is if you have the 250 million to build a refinery. Even at Geco and Flin Flon it was some expensive to get the 0.10 OPT out of the massive sulphides by Merril Crowe acidulation cyanide recovery.
Good grade makes it easier, but you really have to pour the cyanide to it for 60 hours or more (up to five days) to get gold and silver out of massive sulphides with copper, bimsuth and lead in it. Not pretty. There have been many small 200 ton per day lead mines in mexico that got 20 to 60 ounces silver out of their ore. They were profitable but often barely so. Some were nice, but had miner problems so closed early. Another story.

All in all it is the story of a feasibility, which the investor can do by watching the price rise to feasibility and getting out about one month before they start. That is the stock price peak. Partners who are going to do the feasibility for you generally take 70 to 85%. Not very interesting often unless the mine is as big as the sky and they are carried right to the moon and back.
