The prospect covers an area originally enclosing three first order and one second order anomaly located by the Airborne Scintillometer Survey if 1952. Preliminary ground investigation was carried out in October 1952 and is contained in 'Preliminary Report on Airborne Scintillometer Surveys by N.H. Fisher and J. Sleiss'. Carborne equipment was first used to locate the anomalies and determine their extent in July, 1953. An Auster aircraft carrying a Halross scintillometer also flew over the area at the same time locating a high only near the first zone. This was carried out by the Territory Enterprise Limited. A survey grid was laid down to serve both the geological and geophysical work. The base line runs north-south for 3,300 feet and traverse lines run across it at 100 ft. intervals. The detailed radioactive survey covered the whole area. Traverse lines were read at 300 foot intervals in the outer sections where closer work was not warranted. The work commenced in August and was completed in October 1953.

The Radioactive Section of the Bureau of Mineral Resources expanded its operations in the Katherine-Darwin Area during this quarter. The staff working in the area has been considerably increased, but more geophysicists are required. Regional geological mapping has commenced for the season and has disclosed one prospect showing radioactivity in the Burrundie district. Detailed geological mapping and radiometric gridding is being done at Burrundie, Brock's Creek, A.B.C. and Adelaide River Prospects.

Assessing the regional prospectivity of tight, shale and deep coal gas resources in the Cooper Basin is an integral component of the Australian Government’s Geological and Bioregional Assessment Program, which aims to encourage exploration and understand the potential impacts of resource development on water and the environment. The Permo-Triassic Cooper Basin is Australia’s premier onshore conventional hydrocarbon-producing province, yet is relatively underexplored for unconventional gas resources. A chance of success mapping workflow, using rapid integration of new and existing data, was developed to evaluate the regional distribution of key gas plays within the Gidgealpa Group. For each play type, key physical properties (e.g. lithology, formation depths and extents, source rock and reservoir characteristics, and rock mechanics) were identified and criteria were used to assign prospectivity rankings. Parameter maps for individual physical properties were classified, weighted and then combined into prospectivity confidence maps that represent each play’s relative chance of success. These combined maps show a high chance of success for tight, shale and deep coal gas plays in the Nappamerri, Patchawarra and Windorah troughs, largely consistent with exploration results to-date. The outputs of this regional screening process help identify additional areas warranting investigation, and may encourage further exploration investment in the basin. This methodology can be applied to other unconventional hydrocarbon plays in frontier and proven basins.

The map has two sheets. The first sheet shows resources of rare-earth elements by regions. The second sheet shows resources by deposit types.

This prospect, which is situated near the headwaters of the South Alligator River on a bearing of 109 degrees and about 24 miles distant from Goodparla Homestead, was discovered by Geologist, B. P. Walpole, on 2nd June, 1953. Following its discovery detailed geological and geophysical investigations were undertaken as well as costeaning and diamond drilling. [A summary of the information concerning the prospect available at 31st October 1953 is given below].

Uranium-rich igneous rocks are recognised as an important source of metals in uranium mineral systems. Magmatic-related uranium mineralisation may be orthomagmatic in origin, forming via favourable igneous processes, or may result from the exsolution of uranium-rich fluids from particular magmas. Additionally, it is recognised that igneous rocks also may contribute directly to basin-related uranium mineral systems as a metal source. Thus, mapping of the distribution of uranium in igneous rocks has the potential to highlight prospective regions for uranium mineralisation at a macro-scale. Geoscience Australia has produced a series of three digital maps showing the uranium content of igneous rocks across Australia, drawing together geochemical and geological datasets from disparate open file sources. Map 1 shows the uranium concentration in whole rock geochemical analyses plotted as point data on a background of igneous rock type, which itself is derived from Geoscience Australia's 1:1 000 000 national surface geology map. Map 2 integrates these datasets, and shows the average uranium content of all intersecting geochemical data point for outcropping individual igneous rock units. In Map 3, a similar approach is employed in mapping the average uranium content of igneous rocks occurring under cover, using interpreted solid geology coverages. Combined, these maps provide a comprehensive picture of the province-scale trends in igneous uranium content across the continent. Using an applied knowledge of processes leading to uranium concentration in magmatic systems, igneous rocks exhibiting a favourable combination of factors are able to be identified for further analysis of prospectivity for uranium mineral systems.
