A rare earth elements (REE) associated with baryte-apatite veins prospect at the eastern foothills of the Harts Range.
One old mica mine was also located here.

The prospect is a series of fairly narrow (<2m) pegmatite and barite-rich veins that intrude grey-brown schists, gneisses and calc-silicate rocks that lie at the eastern edge of the Huckitta Dome. The more coarsely crystalline veins contain barite crystals to 5cm and the pegmatites contain feldspar crystals to 2 cm. The evolved phosphatic pegmatites with possibly elevated Ba in alkali feldspar contain primary REE minerals. Optical mineralogy has identified the major minerals present as quartz, barite and either limonite or haematite. The main accessory minerals are apatite, monazite and xenotime with minor biotite and kaolinite.
