Located 1/2 mile S of the Jubilee Mine. Reported to have produced 100 oz of gold from alluvial deposits but the information should be treated with caution.
Nearby Cu workings are also called Wallace Gully and are distinct from the Jubilee and Daly mines to the north. The Wallace Gully Cu workings were discussed Hodkinson and Segnit (1989). These workings produced crystallised olivenite, cornwallite and patches of malachite in a granular quartz vein in a fault zone.
