"..we (CUU) don't get 4 times the money or actually get repaid any money"

That's right

However, if we incur an allowable expense, say drilling of 1 million dollars, and Teck opts in for 75%, they are required to invest 4 million in the project

In a sense then we are simply recouping our outlay as we then have a 25% interest in that 4 million dollar improvement in the mine

On the other hand, Teck would only need tp pay 1 million dollars for the drilling if they were paying the costs directly, as if they owned the place, for instance

And then there is the issue of the fact that CUU has, let's say 90 million in allowable costs already sunk into the venture

I bet we are repaid that amount if we are bought out, plus whatever else the guys can get for Liard and the other stuff
