Golfyeti, while you are technically correct, I don't think it is realistic to think that after 4x expenditures they could possibly walk.

Just to clarify this. They didn't need to spend the 4X expenditures if they chose that option. They could have spent, say the $15 million they did last year drilling, and then walked. They would have lost their option, but if they decided it wasn't worth it then they could have spent less money than they did when paying us the first $20 million.

They could have chosen the 75% option and drilled for two years and then bought us out.

What they did was commit to paying us our 25% share of that 4X expenditures up to the point at which they build the mine. That seems to show a great deal of confidence in the project and it was a surprise to many analysts.

What they got by going directly to the 75% ownership was control. There were cheaper ways of achieving the 75% ownership, but not any that gave them the operator control. That has to have been important.
