It's from an article written by Brent Cook to explain the "typical discovery life cycle of a junior development company." He was illustrating when to sell, as you can see we didn't sell when he suggested, but then the company wasn't sold to a major either. Now we have to wait for the buyout to realise some of our ultimate value. Then, if it's Teck, they will realize the real value of the minerals when they build the mine.
