I was more thinking along the grounds of what the likelihood that there will be a substantial copper gold deposit given the size and grade of the lead/silver on top.

I would imagine the economics of getting to the copper/gold would be much better than if it was a deposit on its own at 700m since there will be the whole infrastructure and decline in place for the lead/silver.

Anyway it doesn't matter of it all turns out to be nothing since the lead/silver is more than fantastic on its own - those cores must be so heavy that they can hardly be lifted.
