70 kilometres north-west of Mount Magnet, and 24 kilometres north-east of the Dalgaranga homestead. It is south-west of the Dalgaranga Meteor Crater.

Discovered by prospectors Dan and Don Todd in 1961, mining eluvial tantalite and beryl till 1964. After this a Mr Gray mined the area till he ran into financial difficulties. From 1961-1966 the pegmatite produced 8.89 tonnes of tantalum concentrates, 11.24 tonnes of beryl, and minor tin concentrates. Claumac Pty Ltd purchased the lease in 1966, then immediately tried to off-load it without success. Mining continued however till 1981. Claumac then surrendered the lease, and Goldrim Mining Australia Ltd took over. In 1988 K Seivwright owned the lease. Around 2000, Australasian Gold Mines NL purchased the lease. They constructed a pilot tantalite processing plant just north of the pit in 2001. Mining and the plant closed in 2003.

The pegmatite is 137 metres long at the surface, 12 metres wide, strikes north-east, and dips 20-40 degress south-east. It consists of a 0.5 metre zinnwaldite wall zone, 1 metre intermediate zone of albite-zinnwaldite, and a 2-3 metre grey quartz core, with a repeat of the first two zones on the footwall. The host schist also contains zinnwaldite. In 1962 euclase was discovered for the first time in Western Australia from the pegmatite, although only from chemical analysis.
