Geological report on the Attunga copper mine

Excluding a preliminary visit on September 22nd, four days, November 20th - 23rd was spent on the property. In company with Mr. F. Hanlon of the New South Wales Geological Survey, the surface in the vicinity of the lode outcrops was mapped by plane table on a scale of 100 feet to the inch, and the accessible underground workings mapped in detail and sampled. Cleaning out of the lower "F" Adit had begun at the time of examination, but at the time of writing is not yet complete. This will be mapped at a later date and the results of the examination will be added as an appendix to this report. In addition to the geological and contour map of the surface, plans submitted with this report include a longitudinal section on a scale of 100 feet to an inch, showing the generalised outline of the orebody and the relation between the various outcrops, a more detailed longitudinal section on a scale of 30 feet to an inch showing the distribution of ore values in the principal mineralised section, cross-sections through each of the two principal shafts, and plans of the A, B, and C levels (that of the F level to be prepared later) all on 30 feet to an inch. This report contains notes on the development, general geology, petrology, economic geology, and ore reserves of the Attunga mine.

Department of Supply and Development, Commonwealth Copper & Bauxite Committee fourth report: copper - Cloncurry field

The Committee has given consideration to the desire of the Government to put into production any property that can materially add to Australia's copper output within two years. As pointed out in another submission of even date, it seems probable that 5,000 tons of new copper p.a. can be obtained from a recently discovered ore body in the Mt. Isa Mines, production commencing in January, 1942, if the necessary capital loan is made as recommended. In addition, it seems likely that a worth while production could be obtained from other mines in the Cloncurry district. The principle potential sources of increased supply are Hampden Consols, Mt. Oxide and Trekelano, but many other smaller properties can also be looked to, provided some central treatment facilities are available.

Qualitative BIB-SEM imaging of Proterozoic shales from northern Australia

The Exploring for the Future program is an initiative by the Australian Government dedicated to boosting investment in resource exploration in Australia. As part of the Exploring for the Future program, this study aims to improve our understanding of the petroleum resource potential of northern Australia. 
This data release presents new field emission scanning electron microscopy (FE-SEM) of broad ion beam- polished samples (BIB-SEM) to visualise mineral and organic matter (OM) porosity on 15 Proterozoic aged shales. Samples were selected from the Velkerri and Barney Creek formations in the McArthur Basin and the Mullera Formation, Riversleigh Siltstone, Lawn Hill and Termite Range formations in the South Nicholson region. Qualitative maceral analysis of the 15 samples are described in addition to bitumen reflectance measurements. These samples were analysed at the Montanuniversität Leoben, Austria in June 2020.
The results of this study can be used to improve our understanding of porosity, microstructures, seal capacity and hydrocarbon prospectivity of Proterozoic aged sedimentary basins in northern Australia.

Exploring for the Future—Barometric response function interpretations in the McBride and Nulla basalt provinces: Upper Burdekin region, North Queensland

This report presents key results of groundwater barometric response function development and interpretation from the Upper Burdekin Groundwater Project in North Queensland, conducted as part of Exploring for the Future (EFTF)—an eight year, $225 million Australian Government funded geoscience data and information acquisition program focused on better understanding the potential mineral, energy and groundwater resources across Australia.
The Upper Burdekin Groundwater Project is a collaborative study between Geoscience Australia and the Queensland Government. It focuses on basalt groundwater resources in two geographically separate areas: the Nulla Basalt Province (NBP) in the south and the McBride Basalt Province (MBP) in the north. The NBP and MBP basalt aquifers are heterogeneous, fractured, vesicular systems. This report assesses how water levels in monitoring bores in the NBP and MBP respond to barometric pressure changes to evaluate the degree of formation confinement. 
The main process used to evaluate water level response to barometric pressure in this study is based on barometric efficiency (BE). The BE of a formation is calculated by dividing the change in monitoring bore water level by the causative barometric pressure change. Both parameters are expressed in the same units, so BE will typically be some fraction between zero and one. BE is not necessarily constant over time; the way BE changes following a theoretical step change in barometric pressure can be described using a barometric response function (BRF). BRFs were calculated in the time domain and plotted as BE against time lag for interpretation. The BRF shape was used to assess the degree of formation confinement.
Although there is some uncertainty due to monitoring bore construction issues (including long effective screens) and potentially air or gas trapped in the saturated zone, all BRFs in the current project are interpreted to indicate unconfined conditions. This finding is supported by the identification of recharge at many monitoring bores through hydrograph analysis in other EFTF project components. We conclude that formations are likely to be unconfined at many project monitoring bores assessed in this study.

Data Driven Discoveries Adavale Basin Deep Crustal Seismic Survey (L215) Processed data release and early insights

The Data Driven Discoveries program is a $30.9 million initiative led by Geoscience Australia in collaboration with the Geological Survey of Queensland. The program aims to re-examine decades old seismic data and collect new geoscientific data to identify opportunities for resource discovery in the Adavale Basin located in south-central Queensland. This program supports the Australian Government’s plans to achieve net zero emissions by 2050 by researching opportunities for hydrogen storage, groundwater and minerals within the basin and surrounding areas.
A key component of the program is the Adavale Basin Deep Crustal Seismic Survey (L215), which was acquired from April to July 2023 and collected 1,715 line-km of deep crustal seismic data across the Adavale Basin, Belyando Basin and Warrabin Trough. The survey encompassed seven regional seismic lines (23GA-A1 to 23GA-A7) covering areas near the towns of Adavale, Charleville, Augathella and Blackall in the Adavale Basin, and extending westward through the Warrabin Trough towards Windorah and northward beyond Jericho to the Belyando Basin.
The new seismic survey builds upon work previously published by the program, including the Adavale Basin 2D Reprocessed Seismic Data Package (Geoscience Australia, 2023) and the newly defined chemostratigraphic framework (Riley et al., 2023b). These efforts have significantly enhanced the understanding of the basin's stratigraphy, hydrogeology, resource potential, and underground salt storage opportunities. The modern, high-fold deep seismic reflection dataset produced by the new seismic survey delivers valuable insights into both shallow and deep crustal structures.

Reconnaissance survey of radioactive mineral deposits in the Pilbara goldfield

A survey of deposits of radio-active minerals was carried out in an area between Coongan and Yule Rivers, Pilbara Goldfield, W.A., during September and October, 1948. This was a continuation of the survey commenced in the previous year (Record 1947/078). The survey was mainly confined to an inspection of localities from which radio-active minerals had previously been reported. Some other mineral localities were inspected, and the Geiger counter was used extensively on many types of rocks and detrital materials in the areas examined. In this way an occurrence of radio-active columbite was found at Mount Francisco, and columbite and tantalite were therefore included among the minerals to be investigated. Alluvial samples were all concentrated by means of a yandie. Rough estimates of the reserves of radio-active minerals were made. The findings of the survey are outlined in this report. The geology of the area and the occurrence of radio-active minerals are described. Accompanying geological plans are included.

Notes on heavy mineral beach sands in Dampier Peninsula, north-western Australia

The discovery of the heavy mineral deposit here described was made by the writer during the 1950 field season in Dampier Peninsula, when geological mapping of the area was carried out in conjunction with Mr. Hampton Smith, Consulting Geologist for Ampol Petroleum Co., Sydney. When traversing the southern west coast from Broome to Carnot Bay the writer noticed the presence of black-sand beaches in several places and he eventually took a sample from one of the best localities. When finalizing the report on the geology of the Peninsula, the writer asked for a detailed analysis of the sample. It was then discovered that it was composed mainly of ilmenite. The report provides an outline of the local geology and physiography. The location, composition, and extent of the deposits are discussed.

The electrical resistivities of wet soils

This report deals with an investigation of the electrical resistivities of a variety of wet surface soils, gravels and sands. The work may be regarded as preliminary to an investigation by Mr. R.F. Thyer into the detection of electrically resistive bodies buried in wet soils at shallow depths. It was required to determine the range over which the resistivities of surface soils vary, and also the changes that may be expected in any one type of soil between measurements made within any 1 foot of each other. Measurements were made in four localities, three being in the bed or on the banks of the Molonglo River, where the surface materials are sand, gravel, silts, and in some places, clay. The fourth locality was near the head of Sullivan's Creek, where the soil is a heavy black clay.
