Thanks for all your replies, great to have the discussion.

Took the numbers of QB2 from this presentation.

Concerning the reserves, why would we use only 25% of the total reserves if comparing with the sale of 30% of an entire project?

I think we should use 100% of the ressource and assume that our 25% would sell for the equivalent of 30% QB2 no?
