Located 90 kilometres west south-west of Coolgardie, the quarry has taken a round bite out of the eastern side of Boorabbin Rock, 500 metres north of the Great Eastern Highway.
It was originally developed for crushed ballast for the old Kalgoorlie Railway before being abandoned. It contains late Archean Woolgangie Monzogranite, pale grey, medium to coarse grained, biotite monzogranite dated at 2630 Ma.
In the 1990's, the site was rediscovered by prospectors Donnellan and Maynard as potential for dimension stone. A small test pit was excavated on top of the rock about 100 metres to the west of the quarry.
