I agree Rod, the way I read that is KXL has uncovered 3km of the GM. And Sage has discovered (The same?) vein on their own property. So assuming it's the same vein structure that is 9 km in length.
So Sage's portion of the 9km is, whatever they've uncovered plus the distance to the property line .... and then otentially further to the NW.
Does anyone know how far they Golden extension discovery zone is from the property line?
