We get another $20 million if they decide to not proceed? That seems odd, but stranger things could happen I suppose.

Is that a fact, or someone's interpretation?

Its seems to me that if Teck was to make production decision requiring a further installment to be paid - it would have to be positive?

If 20 million was payable upon a negative PD - I would assume they would just continue with the 500k minimum spend on the property. 20 million would allow them to keep thier interest for 40 years?

Eventually this area will be mined. Future copper reserves are limited.
