This silcrete flake blank core, or core-on-flake, is from southwest Queensland. It was collected during a collaborative research project between archaeologists and Traditional Owners to better understand the deep history of the Mithaka People.
The artefact is on loan to Archaeology and Palaeoanthropology, University New England, catalogue name Brokehimarm Above.

A common quarrying strategy in Australia was to make large flake blanks from cobbles and boulders at the stone source, and carry the large blanks away as both sources for smaller flakes and as chopping or scraping tools. These are called ‘flake blank cores’, or ‘cores on flakes’.
The large flake blank core in this model was reduced by striking medium-sized flakes from the dorsal surface. The flake removals were spaced well-apart along the blank’s distal edge, resulting in sharp points between the flake scars. Often the resulting jagged edge was made more regular by removing the points in the boundary areas between flake scars by tapping off small flakes down the core face. This technique is called ‘overhang removal’. This core is a clear demonstration that overhang removal was an unnecessary for successful core reduction.
Brokehimarm Cave is located near Moondah Lake at an elevation of around 80 metres. The site complex has a number of silcrete outcrops on the top of the low relief escarpment, but this artefact was found in an extensive scatter approximately 100 metres long and 20 metres wide immediately below the cave. The material looks very similar to the material in the outcrops above the cave site. There are a number of other features in the landscape nearby including a large stone arrangement, possible initiation circles, knapping floors, earth ovens, and potential gunyah (hut) remains.
