Nolans Bore Deposit

Nolans Bore Deposit, Nolan's Bore (Western Australia)The Nolans Bore rare earth element-phosphorus-uranium-thorium deposit.Deposit type: Magmatic, CarbonatitePrincipal minerals: allanite, monazite, Ore minerals: (U, Th)Gangue minerals: apatite, phosphate Average grade: 0,6 %Host rock types: carbonatiteStatus: OccurrenceCompany: Arafura Resources NL (1999)

130 km N of Alica Springs, 8 km W of Stuart Hwy. In places REE grades excedes 10%.

The deposit contains an estimated 30.3 Mt of rare-earth mineral resources, at an average grade of 2.81%, resulting in an estimated 850 kt of rare-earth oxides present. In addition to the production of rare earths, the project is of interest for co-products of uranium oxide and phosphate, and a gypsum by-product.

The rare earths at Nolans Bore are contained in several minerals, primarily apatite and monazite (both phosphate minerals) and allanite (a rare-earth silicate). Thorium and uranium levels have consistent values.

The Nolans Bore deposit, located in the Aileron Province of south-central Northern Territory. It consists of steeply northwest dipping apatite veins.
