An unmined copper deposit about 6km N of the Cattle Grid mine, Mt Gunson.

The Windabout deposit is a totally concealed, flat lying body of copper sulphide mineralisation at about 65 metres average depth. Like the MG 14 deposit, it is hosted in carbonate-rich sedimentary rocks at the top of the Tapley Hill Formation shale, but Windabout is larger, with areal dimensions of 1.5 km by 0.8 km. Economic copper mineralisation averages approximately 2.7 m in thickness, ranging from 1.5 to 8 m. The mineralised zone dips gently northwards from 50 metres depth in the south east to 80 metres deep at its northern extremity.

Like MG 14, there is evidence of vertical zonation in the copper sulphides, from high tenor bornite-chalcocite and the cobalt sulphide carrolite in the upper carbonate-rich beds, to lower tenor chalcopyrite in the darker mudstone facies beneath. The Windabout sulphides are coarser grained than those at MG 14.

A JORC compliant resource was estimated by F J Hughes, a consultant of Stuart Metals NL, in 1997. This Indicated Resource is 18.7 million tonnes averaging 1% copper, 0.05% cobalt and 10 g/t silver.
