Possible metallic mineral products of porphyry / skarn and iron oxide - associated copper-gold (IOCG) mineralising systems related to fractionated high level Cambrian to Ordovician igneous intrusions were the targets of exploration in the Coonalpyn -...

The Groundwater (Border Agreement) Act of 1985 provides the legislative framework for the joint management of the groundwater resources along the South Australia/Victoria State border. The Act established a 40 km wide Designated Area along the...

Exploration for possible economic Tertiary lignite and coal seams within sediments overlying the northern flank of the Padthaway Ridge palaeo-archipelago in the western Murray Basin has consisted of the drilling and geological/geophysical logging of 7...

Exploration for possible ancient beach strandline heavy mineral sand placer deposits formed within the Pleistocene Bridgewater Formation has been undertaken in the State's South-East region. This pioneering on-ground work came about after several...

The purpose of this interpretation is to provide an initial framework for the basement to the Murray Basin upon which to plan the Geological Survey of South Australia’s MinEx CRC National Drilling Initiative drilling project targeting the Delamerian...

Crystalline basement in the Delamerian Project area is defined as Ordovician and older rocks which were affected by the Cambro-Ordovician Delamerian Orogeny and older tectonic events. It thus includes the rocks of the Adelaide Geosyncline, Kanmantoo...

AusLAMP is a collaborative national project aiming to cover Australia with long period magnetotelluric (MT) survey data acquired on an array having ~55 km spaced stations. Signatures from past tectonothermal events which have deposited conductive...

The results of a study undertaken to produce depth estimates to the top of magnetic anomaly sources are presented within this report. The area of interest is located within the present-day preserved footprint of the ~500 Ma Delamerian Orogenic Belt,...

The best available ground gravity and aeromagnetic data from South Australia, New South Wales and Victoria which were acquired over the region of the Delamerian Orogen have been merged into continuous datasets to facilitate geological interpretation,...

Gold and base metal exploration in an area extending north and north-east of Kingston South-East comprised image interpretation of SAEI aeromagnetic data, plus ground magnetic surveying and RC and diamond drilling of 6 selected magnetic anomalies (6...

Gold and base metal exploration conducted in an area extending west and south-west of Keith was aimed at porphyry style gold-copper mineralisation akin to that associated with the Staveley Belt in neighbouring western Victoria. Work undertaken...

Gold and base metal exploration undertaken in an area extending to the north and south-east of Meningie comprised image interpretation of SAEI aeromagnetic data, plus the conduct of ground magnetic surveys over and then test RC / diamond drilling of 6...

Shallow aeromagnetic targets in the vicinity of the Padthaway Ridge were investigated in the Sherlock area, 35 km east of Tailem Bend. Ground magnetic surveying follow-up, and a program of 41 rotary mud / diamond drillholes (respective total...

Cambrian rocks lying beneath relatively thin Phanerozoic cover on the western edge of the Murray Basin were targeted by CSR principally for stratiform volcanogenic massive copper sulphide deposits, and for epigenetic Palaeozoic gold occurrences...

Eight buried anomalous gravity/magnetic bullseye features in the Coonalpyn - Tintinara area, previously identified by CSR Ltd from SAEI aeromagnetic data and regional gravity surveying, were followed up by ground magnetic, Sirotem and IP surveys. The...

Exploration for possible volcanogenic massive sulphide or Mount Isa - type replacement style epigenetic/hydrothermal base and precious metal deposits within Cambro-Ordovician basement in an area located north of Coomandook has consisted only of a...

This gravity survey, conducted between 1st April and 30th May 1970, consisted of a total of 1603 field stations laid out on east-west lines 2000 feet apart, with a 400 foot station spacing. The results show a very strong regional effect of 21.5...

A wide-ranging geochemical exploration programme has continued, testing soils of the region for possible mercury emissions from basement, by performing laboratory analyses of samples of the soil vapour after these were first trapped in shallow auger...

In a continuation of geochemical exploration for possible large blind base metal sulphide orebodies which may have formed within the concealed Cambrian basement, North Broken Hill carried out infill sampling of significant mercury soil anomalies (>...
