I don't think they have the option of waiting till the end of the year.

They always have the option of walking now, and trying again later, or only opting for a percentage. I just meant if they can't agree on a price, as JayJ was suggesting, then Teck could opt in and spend their money drilling this season. However, at the end of the year with the results of that drilling known, the property will be worth more and the original price might not be so bad. In effect Teck has to think through what the results of another year of drilling will prove up and act on that now if they're to secure the property. It's kind of a circular logic.
