The Bulletin prospect is about 20 kilometres south-east of Sandstone, and north north-east of the Ladybird prospect.
It sits on the eastern limb of the greenstone belt, in an area of metabasalt and metadolerite, as well as thin sedimentary marker beds of chert and banded iron formation, with much folding and shearing.
At the site is a 250 metre line of shafts following the line of lode, and exploited historically for 355 metres in length. Quartz veins are hosted by fine grained metabasalt. From 1911-1912, and 1936 to 1937, historic production was 943 ounces of gold.
Modern exploration drilling focussed on three areas. The first was directly west of the north-south main zone of the historic workings. Widespread low level gold anomalies was found in goethite altered quartz stringers within a porphyry intrusive.
The second area was south of the workings, along the line of lode. Mineralisation was found associated with banded iron formation and metabasalt, hosted in quartz stringers in an upper saprolite zone, and open to the south for 600 metres.
The third area was 500 metres east of the workings. Here was found a north-south striking mineralised zone associated with west dipping banded iron formation. The best gold grade was 1.80 g/t from 11 metres, with mineralisation open to the north.
The source notes the main reef was not drilled, and other gold found was erratic, and thin.
