The pegmatites are near the entrance track to the Curlew Emerald Mine, on the Marble Bar-Wodgina Road. Kimber (1984) identified the largest nine pegmatites, and GPS co-ordinates suggested of the largest is 736,547E 7,609,531N UTM50 AGD84.
Limited mining of 0.34 tonnes of cassiterite-yttrotantalite concentrates happened in the 1960's, resulting in several small pits and trenches. Further alluvial material was collected from 1980-1982 by Pilgan Mining Limited amounting to 10 tonnes of concentrate. An author in the reference observed the concentrates in 1982, containing a mixture of formanite, microlite, monazite and cassiterite.
The largest pegmatite is described as tantalum and rare earth bearing in a 200 x 10 metre area, on the north side of Tambina Creek, with further pegmatites to the north-west. The map in the reference (from Kimber 1984) shows the largest pegmatite just north of the Marble Bar-Wodgina Road.
The pegmatites have intruded into an Archaean metamorphic greenstone inclusion of metabasalt and meta-ultramafics near the western edge of the Shaw Batholith. There are two types of pegmatites in the group. The first shows cassiterite, monazite and tanteuxenite, as sub-parrallel swarms less than 0.5 metres wide dykes. The second are deformed and boudinaged albite pegmatites, zoned with quartz cores, and containing beryl, formanite, lepidolite, muscovite, spodumene, yttrotantalite, and zinnwaldite.
