Interesting spot on page 15 of the below report mentions the Ore Reserves in Gubong mine is 150,000 Tonnes

This equates to 150m Kilogrames =  150 Bill Grams & that equates to 4,822,612,049 Troy Oz's

Taechang Mine has 50,000 Ore Tonnes Reserves = to a third of Gubong or 1,591,461,976 Troy Oz's

However the Ore Reserves do not equate to completely 100% Gold Oz's, but it gives us an idea of the size & remaining potential of these mines.

What's your view on the remaining Ore reserves Dingoheeler?
