3.5 kilometres north-east of the Onedin prospect. Maps place it bordering the Tanami Road, about one kilometre south of its intersection with the Great Northern Highway.
Hosted by the Onedin Member (originally known as the Mimosa Member informally by company geologists in the area) of the Koongie Park Formation. The Onedin Member consists of carbonate, carbonate breccia, sandstone, mudstone with thin quartz bearing mudstone units.
No gossan outcrops at the site, however it is marked by numerous pods of silicified carbonate, intruded by quartz-phyric and aphyric rhyolite.
The deposit is wrapped around a north-east plunging anticline, with faulting and shearing on the northern limb.
Near the Rockhole deposit is abundant vesicles in quartz bearing mudstone clasts of quartz bearing mudstone breccia facies, possibly pumice fragments. Phlogopite is abundant according to the source.
The Koongie Park Formation in the area is overlain by the Moola Bulla Formation in the south, intruded by a sequence of granitoids of the Sally Downs Supersuite, and in the north-west the Loadstone Monzogranite, and east leucogranite.
The Koongie Park Formation consists of mafic and felsic volcanics and associated sedimentary sandstone, mudstone, carbonate, chert and ironstone, intruded by rhyolitic to rhyodactic sills, dolerite bodies, and basalt dykes, in the central area of the Halls Creek Orogeny.
The Koongie Park Formation is divided into two units, being a lower unit of basalt, dolerite, interbedded sandstone and mudstone, chert, ironstone, and
poorly sorted pebbly sandstone facies. The interbedded sandstone and mudstone dominates, with isolated outcropping of chert. Large areas of basalt and dolerite occur to the north and west.
The upper unit of the Koongie Park Formation is more diverse, with abundant felsic volcanic facies and carbonate, sandstone turbidites and mudstone, and less abundant ironstone, black mudstone, granule conglomerate, volcanic clast bearing mudstone and breccia deposits.
The formation is part of all the deposits listed under the Koongie Park Community Mindat sub-heading. Base metal deposits are found in the upper part of the formation.
