Geological regions with abnormally high endowment in metals appear to have resulted from the fortunate juxtaposition in space and time of numerous, possibly exceptional, processes. The gold mineral system of the Eastern Goldfields Superterrane (EGST) is an example. In order to understand why this is so, we have taken an approach that considers the mineral system as a series of integrated components known as the Five Questions: viz 1) geodynamics; 2) architecture; 3) sources & reservoirs; 4) drivers & pathways; and, 5) depositional mechanisms. In order to better understand these components and the geological processes that define them, a range of scales needs to be considered. However at each scale the relative benefits of considering any one of the five components varies. Ultimately the aim is to use this scale-integrated process-based understanding for prediction. Understanding why a region is particularly endowed or a deposit so rich is important but only half the question. The other half is where is the next favourable region and/or camp and deposit? In this regard, we 'Answer' the Five Questions.

The purpose of the presentation was to show mineral explorers how recent results from the Gawler Mineral Promotion Project may be used in their quest for blind iron-oxide copper gold (IOCG) deposits in the Gawler Craton. The Gawler Project ran from late 2000 to early 2006. The project developed new methods of exploring prospective basement beneath deep cover.

A magnetic survey of the Kunimo creek area near Kuta in the Central Highlands of New Guinea was carried out between July 17th and July 28th, 1950. It was hoped that the survey would trace the course of the auriferous wash originally laid down in the bed of a former creek but now concealed by overburden of soil and unconsolidated volcanic ash. This report gives an account of the magnetic survey and its results.

Gold Mining Lease 1075 is situated at the head of Rowlands Creek, a tributary of Barola Creek. The workings are on the hillside just south of the head of Rowlands Creek and approximately five miles west-south-west from Kainantu Sub-District Office and Airstrip in the Eastern Highlands of New Guinea. The elevation of the workings is approximately 6,200 feet above sea-level. The area was examined by the writer in April, 1953. [The history and development of the lease, transport and resources, general geology, ore geology, the occurrence of the gold, and further prospects, are discussed in this report].

This report is compiled of four separate reports. (1) "Note on the Application by the Chamber of Mines, W.A." Yield, production, industry costs, and the subsidy proposal are discussed in this report. (2) "Proposal for a Subsidy to the Gold Mining Industry". This report is concerned with details of the economic position of the mines and Western Australian gold industry as a whole. (3) "Supplementary Report on the Proposal for a Subsidy to the Gold Mining Industry". This report summarises the findings of the earlier enquiry into the position of the Western Australian gold industry. (4) "The General Effect on Gold Mine Surplus of Assistance based on Production". The object of this note is to outline briefly some of the principles which require consideration in determining whatever form of assistance may be decided.

The presence of alluvial gold in the river gravels of Mastuj and Chitral has been known for many years, and local inhabitants have realised the value of the gold and have worked the deposits. Tipper (1923), Coulson (1937), Ikramuddin Ali (1951) and Tayyab Ali (1951), have reported on the placers but no accurate determinations have been made of their size or grade. In August, 1951, the Australian Geological Party, J.F. Ivanac, D.M. Traves, and D. King, examined the deposits between Mastuj and Drosh, with the objects of reporting on the size and nature of the placers, and if warranted, to suggest suitable sites for testing. This report gives an account of the examination and its results.
