The area is underlain by Upper Cretaceous Kasalka Group rocks comprised mainly of andesite, rhyolite, tuffs and breccia.
The showing is located approximately 1.6 kilograms below the past producing Lorraine (Victoria) deposit (093L 129). The showing is an exposed band of rhyolite which is irregularly mineralized with malachite. In 1929, a sample from the best mineralized area over 7.6 metres assayed traces of silver and gold with 0.4 per cent copper (Minister of Mines Annual Report 1929, page 168).
