From the recent Annual Report "The Torrens anomaly is one of the largest and most geologically prospective Iron Oxide Copper-Gold (IOCG) exploration targets in the world. The Torrens anomaly is enormous. Specifically, it is estimated that the volume of subsurface rock with both the density and magnetic susceptibility of IOCG ore totals approximately 13 billion tonnes – potentially larger than Olympic Dam"

Not many of us can remember the past drilling result and potential resources at Torrens.
Anyone can give us a hint, pls.
Thanks
