This locality has been incorrectly listed on Mindat in the past as ' Yinnietharra pegmatite'.


Also known as the Tobin Well pegmatite, Marloo 2 pegmatite, and the Arthur River South pegmatite. There is much confusion over this location in the literature, and the mine has been given a number of names. Further the literature has given a number of different locations for this remote site on the eastern fringes of Bidgemia Station, west of the main Yinnietharra mineral field. The reference concludes after studying all available sources, it is 6.7 kilometres due south of Pyramid Hill.

It is the type locality for clinobisvanite. The species was discovered by P. Bridge from the CSIRO in 1972, after studying specimens the organisation collected from pegmatites in the Yinnietharra area in 1971. Later in 1972, R.M. Clarke discovered the species from the Londonderry pegmatite from material also collected by P. Bridge. A reassessment of the CSIRO collection uncovered a further three localities for the species; Wodgina, Menzies (?), and the Champion Gold Mine near Westonia. In 1973, E.W. Bing from the CSIRO found the species in a recently submitted sample 1.3 kms north-west of Corinthia, north of Southern Cross. All localities were in Western Australia. Subsequently a prior description was found for the Mutala pegmatite area, Mozambique, however the mineral was never named, so the type locality went to this Yinnietharra pegmatite.

Clinobisvanite occurs at the Kempton mine as soft friable yellow coatings, orange globular aggregates, and rarely small groups of reticulated plates up to 0.1mm across, intergrown with bismutite on spessartine garnet crystals. Its is frequently associated with its polymorph pucherite.

The mine is named after the three Kempton brothers; Bob, Eric and Les; who around 1979 pegged the location, and mined beryl and tantalum-niobium to a limited degree. In 1982 it was explored for scheelite by the brothers in conjunction with with a company called UGA, but the deposit was sub-economic.

The pegmatite is 300 x 40 metres in size. It contains a wall zone of coarse grained microcline-plagioclase-quartz-muscovite, and a core of microcline. Massive spessartine, red plagioclase, muscovite, quartz, irregular shaped cleavelandite, columbite-tantalite is common at the site when inspected by one of the authors of the reference many years ago. Euxenite is claimed from the location as black, metamict, vitreous masses, with yellow ochrous blebs of possibly pyrochlore, but both species are yet to be confirmed from the location.
