The site contains a scattered collection of shaft groups, small pits and trenches, just south to south-east of the indistinct access track.

Small gold area, 60 kilometres east of Marble Bar, 10 kilometres west of the Nullagine River crossing on the Rippon Hills Road, and about 5 kilometres north of the road, at a location on maps called Bullgarina Hill. Information on the location is severely lacking.

Access appears to be a bulldozed track of unknown quality, but likely poor, to a north-south one kilometre long bulldozed alluvial area about one kilometre north of the road. The track then turns east for about 5 kilometres to a small collection of historic workings.

Appears active 1930's, and mapped 1939 by K.J. Finucane.

There are also several small exploration pits between one to five kilometres north of the Rippon Hills Road between Mooyella and the Nullagine River crossing that no information, even names could be found.
