RE: ZNR compared to CEV Capex is in a remote location, but Zone might as well be on the moon ! The Capital expenditures for Adrianna is estimated at 12 billion and it is south of Zone. Zone better have atleast 10 billion tonnes to even get considered for development due to it's location. In conclussion Zone needs a lot of Capital to prove up it's resource, I believe that's why Grandich was hired by them to bump up the sp for a pp imo. Might be worth a shot with a small amount of capital ( very small) and I wouldn't pay a cent over 0.095 for it due to the heavy flipping.
Good Luck
