What do you mean by "unsustainable business models?" Isn't their demand for gold and gold products and isn't their limited supply? Is it difficult to get gold and other precious metals out of the ground? Isn't gold used in economic/monetary and geo-political purposes? It employees alot of people and in some countries they are extreme influential? I don't understand your premise. Because GG and others (also gold itself) are correcting doesn't mean the industry is falling apart. This is once again people someone going crazy and think the sky in falling. The sky isn't falling and gold and GG will be back up to old highs by next year. Do you even have a position in gold or are you trying to make point on gold in general, without even having experience in it?
