The thing is anyone who took the time to figure out how physically big the Hinge could be (probably is) and used the ounces/ton figures on the SGR fact sheet, could have figured out tonnage and subsequent ounces. I believe some previous poster did just that, yet it takes an overpaid analyst from TD to give it cred. Let's just say that 50 metre expansion from the last NR added considerable tonnage to my model.
