This is a small, little known gold area, twelve kilometres south of the Moyagee gold mine, and about the same distance west of the highway, along an east-west station fence. Several historic shafts stretch in a line north-south for several hundred metres, running north of the fence line.
In 1909, R.M. Miller and Henry Koehler applied for a lease here they called Moonlight. Several others across 1909 to 1911 applied for neighbouring leases, which were soon abandoned. The Moonlight continued with several crushings before the lease was forfeited in 1916.
In 2015, Ramelius Resources began exploring the site to access the feasibility of an open pit mine. They estimate a maiden resource of 490 000 tonnes of ore at 2.5 g/t yielding 39 000 ounces of gold.
The lodes strike for 350 metres as a number of sub-parallel steep west dipping quartz sulphide lodes in basalt rocks. The lodes are 2 to 5 metres wide, 10 to 20 metres below the surface. The lodes are covered by 8 to 15 metres of transported laterite. At the base of this is a 2 to 5 metres gold enriched supergene blanket.
