Report on Iron Ore Deposits – Yampi Sound (Western Australia) – A Montgomery -1920

Short Description

Original report of the Department of Mines of Western Australia dated 1920. Authored by A Montgomery State Mining Engineer.

Yampi Sound is in North Western Australia and the ore bodies investigated at Cockatoo Island and Koolan Island are not only impressive in terms of scale but in terms of grade (65% straight out the ground). Koolan was been and continues to be exploited, currently successfully by Mt Gibson Mines. Cockatoo is underway yet again but the path looks a little treacherous for the incumbent.

32 pages octavo, in thick card covers, Annotated at front as a gift from Alfred Jones, Queensland Minister for Mines in September 1921 to Jack Reid mining identity.

A super report and despite being ex library (cancelled stamp at front) is scarce and near impossible to come by – why do they let these things go. The charts / diagrams on separate loose sheet in the wallet at the back are of good quality and include a facsimile of the Admiralty Chart of the broader locale; A map from Campbell’s Report of 1908; Map of Koolan Island; Longitudinal and Cross Sections of the main bed at Cockatoo Island and Koolan Island Main Lode.

Not sure, but one can’t help thinking that the information gleamed from these reports which started with pencil and paper gets to the point quickly and more economically than today’s plethora of multiple dimensional graphic and seismic analysis … and the accommodation has definitely gone upmarket – at least at Cockatoo!

Yumpi sound almost all iron ore – still going.
