Located 13 km west south-west of Ashburton Downs Homestead, and approximately 3 kilometres west of the Bali Lo deposit.
The mineralogy of the Ledge deposit differs from that of other deposits in the area, by the relatively high proportion of secondary phosphate minerals. It sits on the same anticlinal structure as the Bali Lo, Anticline and Bali East deposits.
Four separate pods along a length of 50 metres in a 2 metres wide silicified shear zone, mineralisation in limonitic quartz filled breccia. Lead is concentrated at the western end. Minor copper production is reported in the 1960's via a trench and small open cut.
16 valid minerals.
