Owen, H.B., 1953. Manganese deposits near Ragged Hills, Gregory Range, North-West Division, Western Australia. Record  1953/062. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

Manganese deposits in the Gregory Range, Western Australia were examined and mapped by officers of the Geological Survey of Western Australia and the Bureau of Mineral Resources jointly. The investigation indicated the presence of 93,000 tons of manganese ore distributed between 37 separate bodies contained in 13 groups. Numerous small bodies each containing less than 200 tons of ore have not been included in the tonnage estimate. The grade determined by chip sampling the surfaces of the outcrops is generally high. The range of composition of samples is: [see table in record]. The deposits occur as replacements of silicified bands in dolomitic limestone and as fillings of irregular cavities in the limestone. A few thin deposits in the south-eastern sector of the field overlie quartzose rocks.
