Rox Resources begins drilling at Marqua phosphate project in Northern Territory

Rox Resources (ASX: RXL) is working towards expanding the potential size of the phosphate prospective area at its Marqua project with the commencement of reverse circulation drilling.

This drilling will test the extent and grade distribution of phosphate mineralisation previously identified in 2008, as well as targets generated by recent soil sampling and geological mapping undertaken by Rox.

The phosphate target horizon at Marqua extends for over 30 kilometres in length and to date has only been drilled sporadically.

Rox’s drilling will provide a more complete picture of the extent and potential of the phosphate deposits and also investigate two known higher grade zones.

The program consists of about 30 holes for around 2,000 metres. Results from the drilling will be reported to the market as they become available.



Marqua Potential

The Marqua phosphate project in the Northern Territory is located around 450 kilometres east of Alice Springs and 300 kilometres south-west of Mt Isa.

The project is located in the Georgina Basin which contains 90% of Australia’s hard rock phosphate resources.

A 25 kilometre long strike length of phosphate bearing rocks has been identified by surface sampling, which showed up to 39.4% phosphorous oxide, and drilling, which returned intersections of 6 metres at 19.9% phosphorous oxide and 5 metres at 23.7%.

Importantly, there is the potential to establish a large resource in a new phosphate area. Marqua has an exploration target of 50 to 100 million tonnes at 15 to 20% phosphorous oxide.

The only operating mine near to the region at present is at Phosphate Hill in Queensland, which is producing 2 million tonnes per annum.

Other developing phosphate projects in the basin are the 461 million tonne at 18.8% Wonarah and 305 million tonne at 15% D-Tree (Lady Annie). 

Marqua, which covers about 2,600 square kilometres, is strategically located only 250 kilometres from the nearest railhead and gas pipeline at Phosphate Hill.

Rox was granted the Marqua tenements for a period of six years in April this year.
