Hi Tradeprofits, lol, you obviously have no idea what you are talking about.
A Proven ore reserve must be economical to extract in current conditions among other criteria. To determine that they need a revenue estimate. The higher the "Revenue" figure allows more of the ore body to be classified as "Proven", as more of it is economical to extract.
As per the RNU reserve Estimate document in my post above they have used the Downstream project economics as their Revenue estimation metholodgy, not the revenue from the upstream mine as a stand alone operation.
Hope that helps you once again.
