Thanks RW, I had in mind a room and pillar style underground targeting the root. The next question would be what is the max depth we could/would go as an open pit? I guess what I am trying to wrap my head around is how best to capitalize on the high grades at depth? What is the lowest economic grade to dig through to get to the goods at depth? Would you mix this lower grade material with starter pit material in order to get there? Or will the starter/initial pit last long enough (decades) that by then it will be economical to process the lower grade material above the sweet caramel center?
