Sandstone from the Piles Creek quarry has been quarried and sought after for nearly 50 years because of the oxidizing characteristic of the deposit. The 'cream' range is lighty oxidizing and the 'guinea gold' is similar to the oxidizing sandstones of the Sydney 'Yellow Block' region. The percentage composition of the iron oxides and siderite is proportional to the degree of oxidization.
