I'm looking for a good penny stock investment in the copper mining sector. It doesn't matter where the company's mining operations are based as long as their shares are traded in the U.S. or Canada. I'm acting on the advise I got from this book I bought on Amazon "Good as Gold: How to Profit from the Coming Boom in Copper". Actually it was free once I downloaded the kindle app onto my PC. So, share those ticker symbol please.
