Boring on Recent sand dunes has intersected sediments which become more clayey with depth below a thin layer of fine well-sorted sand. Deletorious organic matter was detected in the samples which contained more than the specified silica content (93%...

Reserves in the deposit amount to 230 000 cubic yards above the level of the access road. The marble is predominantly white to pale grey in colour. Some small patches of pale pink stone are present, but selective mining of this material is not possible.

Considerable reserves of flagstone from the Mintaro Shale horizon and similar to the stone quarried near Mintaro township are available in the property examined. Depth of soil overburden and the presence of sandstone layers in the shale need to be...
