For information on the moolooite type locality see the main Mooloo Downs Station sub-heading. This quarry location you are reading relates to marble. Located 6 kilometres south-west of the Mooloo Downs pastoral station homestead, and 5 kilometres west of the Cobra-Dairy Creek Road.

Explored by Newmex Exploration 1981 to 1982. In the early 1990's a small trial pit was developed known as Cameron's Open Cut. This is 7 metres wide, 30 metres long, and 5 metres deep. Some marble blocks were extracted over a short period.

The marble is hosted by steep dipping green weathered micaeous schist, amphibolite, and minor quartzite. The marble is a lens shaped body, forming a low north-west trending ridge. The lens outcrops 175 metres long by 50 metres wide, tapering to the north-west.

Dolomitic marble, pure white, fine to very fine grained, with interlocking carbonate crystals, which give a mirror like finish when polished. The quartz parts are penetrated by steep dipping, anastromosing veins of pale green schistose serpentine from 20 mms to 1.5 metres wide.
