The Proterozoic Curnamona Province extends across central eastern South Australia and into western New South Wales. Whilst most of the Province is obscured by younger sedimentary cover, regions of exposure are present in the northwest as the Mount Painter and Mount Babbage Inliers, and in the south as the Willyama Inliers. The Willyama Inliers expose the largest area of basement, consisting of a complex of late Palaeoproterozoic metasedimentary and metavolcanic rocks (Willyama Supergroup), and local metamorphosed intrusives, together with early Mesoproterozoic volcanic and sedimentary rocks and granitic intrusives. The Willyama inliers are further subdivided into the areas in the vicinity of Olary (mainly in South Australia) and Broken Hill (mainly in NSW).
