Highland Plains, Northern Territory, Australia

The Highland Plains Phosphate Project has a JORC Code (2004) compliant Inferred Resource of 53 million tonnes at 16% P2O5.

Since POZ Minerals listed in 2008, substantial amounts of drilling and other work have been done at Highland Plains with proposed solutions for beneficiation demonstrating higher grades.

The Company is currently targeting the production and sale of up to 3 million tonnes per annum of beneficiated rock phosphate from Highland Plains, to be transported by slurry pipeline to a barging facility in the Gulf of Carpentaria for export.

Extensive flotation test work has resulted in a quality grade of 32.3% P2O5 at 76% recovery from the coarse and fine fractions.

Groundwater test work (pump testing) was very positive with the best bore resulted in flows of approximately 15 litres/second from shallow depths which indicates potential yields of at least 25 litres/second with the maximum rate not determined due to capacity limitations of the pumping equipment.

Initial fauna and flora fieldwork surveys have also been completed.


To the west of Highland Plains are areas of significant phosphate exploration potential. These areas lie along the prospective Cambrian-Proterozoic contact which also hosts the Highland Plains deposit. Geomorphic embayments which appear similar to the Highland Plains embayment represent excellent future drilling targets and are on granted POZ Minerals leases.

The Highland Plains deposit is only 68km west of the Century zinc mine which utilises a slurry pipeline to the coast and the open pit production at Century is recently ceased. POZ has considerable interest in the Century infrastructure as one possible solution to greatly reduce the capital requirements needed to develop Highland Plains.

An independent scoping study for a slurry pipeline transport solution to the coast for Highland Plains phosphate indicated a 3 million tonnes per annum slurry pipeline would deliver OPEX costings from only A$2.06 to $3.69 per tonne (pipeline operating costs only).

At Port Karumba there are existing port facilities including a slurry de-watering system, bulk storage and operational barging, currently being utilised for zinc concentrate.

We are actively seeking investors who have an interest in financing the potential use of this infrastructure.

The Company is actively seeking partners for this project which is 100% owned by POZ Minerals and has no private royalties.
