Finding more copper below the pit plan, under the mountain, or far from the mine site won't improve our economics. Proving up the waste rock, improving metallurgical recoveries, and drilling the edges of our block model will help our economics.
Economics is one thing and they will improve everything you stated, you can always make it better, they already know how and Teck have their own cost scenario and numbers to work with.
But, Size, Mine life and beyond (staying put for 60+ years) and NSR will get us bought out. And drilling the untested portion of the Paramount will prove that futur potential a major wants to see.
I think that can be done this summer with either back-in option.
