At the most advanced stage is the Highland Plains Phosphate Project, an historical estimate with grade and tonnage for this project was reported in Phosphate Australia's prospectus. However, as it was not reported in accordance with the JORC code that estimate is not able to be stated here. Readers are referred to the prospectus (available from this website) for this information.
The total area of the Highland Plains embayment as a drilling target is 6.5km2. Initial drilling will begin on an area of approximately 1km2, a shallow drilling target area, where historic drilling intersected phosphate mineralisation which commenced from 0 to 3 metres in depth.
The historical estimate above is based upon percussion drilling of 36 holes at Highland Plains for a total of 1,184 metres.
