I was losing. Finally, at Comox airport, I found a British Columbia business magazine. It had all the usual articles, but there was a profile of a guy who mined diamonds. No wonder people buy penny stocks. This was better than the lottery.
Real research is needed.
You could try visiting the companies themselves. The book I got by the Mountie might help you there. A lot of these mining outfits are up in the Northwest Territories, where hardly anybody lives but native peoples and miners. The temperature gets down below -60 degrees Fahrenheit, which is cold enough to make licking a metal pole very very difficult. You'll need good snow tires.
