A lot of information can be found on the company website, a very good site. A lot of good reading too.

NARRABURRA RARE EARTHS & RARE METALS PROJECT
Target: Porphyry or bulk disseminated style rare metals, heavy rare earth elements (REE) and intrusive related gold-REE deposits in fractionated, peralkaline granite complex. Commodities Sought: Zirconium, yttrium, niobium, REE, thorium, rubidium, gallium, lithium, tantalum ... for high-tech industrial market.
Project Status: Following mapping, surface sampling and ground radiometric surveying, RC drill testing of a deeply weathered granitic intrusive with relatively high Zr, Hf, Nb, Th and REE in a 1500m by 500-800m zone of interest in 2006 led to the definition of an inferred oxide resource to 40 metres of 55 million tonnes at 1000 g/t ZrO2, 60 g/t Y2O3, 300 g/t REO, 40 g/t HfO2, 80g/t NbO2 and 50 g/t ThO2. Follow up aircore drilling in 2008 closed off the main zone of interest and produced encouraging results that have significantly added to the area encompassing the known and potential resources.
Positive results also flowed from petrological and mineralogical studies, bench scale tests and preliminary metallurgical tests that were aimed at producing a zirconium-enriched heavy mineral concentrate from friable bedrock material.
Bulk sampling has been completed and selected material was forwarded for metallurgical testing. Results have been positive and joint venture partners are actively being sought to take the Project forward.
