1) Assume every scenario is 25yr mine life and scales off the PFS numbers for base case.

2) Assume no real capital efficiency gain from scaling up. Just a discount on metal production reflecting lower ore grade as production volume increases

3) Run scenarios that scale from PFS numebrs, through to absolute worse case and see what happens to earnings.

4) Look at current MC as % of future earnings multiples...
