Prodigy Gold and the GTO – Why Here? Significance of Callie as a major contributor For personal use only • How much gold is in them thar ‘hills’? • ~200 gold occurrences with a estimated endowment of >20Moz 54Koz 4 • Historically >10 million ounces have been produced in the Tanami (Central Tanami, G
Slide 6: Prodigy Gold – Why Here?
Prodigy Gold – Why Here? Where there are 10Moz deposits statistically there should be more For personal use only 1Moz deposits • Neighbourly Gold; in prospective • There are only a handful of gold deposits >10million ounces in WA…. But there are far Telfer more medium deposits • According to the DMI
