The locals are afraid the toxic chemicals could frig up the water supply. Would you want open pit mining operations in your neighborhood?

With the price of gold at $1500 an once these gold companies have to keep cranking out the PR's to try and sustain stock prices. Gold is a commodity like any other and is subject to commodity price cycles. I wouldn't touch gold now with a ten foot pole. I think gold is at the top of the price cycle. When the price of gold collapses ( it will ) I think you'll see lots of projects delayed or backburnered. Gold is too late cycle and played out. You might have better luck with alternative energy stocks, "cleantech", etc.
