Diamond, gold and platinum group element (PGE) exploration activities carried out within an area of known kimberlitic and lamproitic intrusive rocks east of Elliston comprised aircore drilling (23 holes, total 1188 metres), addressing 17 out of 36...

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...

Diamond and gold exploration undertaken on the two relinquished ground portions located north-west and east of Venus Bay on Eyre Peninsula, which total 530 square km in area, have comprised heavy mineral sampling, heavy mineral grain microprobing,...

Aircore drilling of gold and base metal targets (23 holes, total 1136 m) was undertaken following lag, rock chip and leach sampling and a review of previous aeromagnetic and drillhole data from three separate areas, 40 km west and 50 km north-west and...

Groundwater sampling, aeromagnetic interpretation, shallow auger sampling and isotope studies were carried out over an area 30 km northeast of Elliston. Heavy mineral concentrates from composite auger samples contained zircon, galena and sphalerite,...

Calcrete was sampled over the entire foot of Yorke Peninsula, approximately 200 km by road from Adelaide, to follow up aeromagnetic structures and anomalous base metals in groundwater. Several samples returned slightly elevated base metals, from...

Lag/laterite geochemical sampling carried out 20 km west of Port Lincoln identified certain areas that are anomalous in As. However, no anomalous drillcore assay results were returned from follow-up aircore drilling (5 holes, total 281 m) of a...

Diamond exploration which was undertaken across practically the whole of Kangaroo Island, barring national and conservation parks and reserves, sought to test the potential of the island to contain kimberlite pipes and / or associated rock types, and...

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...

An area near Coffin Bay was taken up to search for exposures of surficial sedimentary material which might be useful to BHP for preparing flux additives to incorporate in the charges of its Whyalla blast furnaces or basic oxygen steelmaking plant...

This inaugural regolith map of the southern Gawler Ranges margin provides a valuable regional overview of the main regolith types and their associated landforms, plus a general outline of the major areas of bedrock or regolith-dominated terrain, as...

The Cu-Au potential of the coastal area between Fowlers Bay and Colona was downgraded by an absence of significant aeromagnetic and regional soil/calcrete anomalies. Calcrete results may, however, reflect the effects of groundwater and seawater...

Three composite samples, taken from five RC drillholes (total 85 m) put down in kaolinised granite near Colley Hill, on testing exhibited poor raw and fired whiteness due to the presence of fine biotite.

In 1975 Blue Circle Cement undertook an assessment of the reserves and quality of deposits of Recent limesand, aeolianite limestone and ferruginous clay which form an active dunefield lying adjacent to BHP's Coffin Bay Tramway in the Port Lincoln...

Early-stage exploration of the State's South-East coastal region for possible economic heavy mineral sand placer deposits in ancient raised beaches has comprised an assessment of favourable geology, historical depositional conditions and...

Three, or possibly four, raised beach ridge deposits were located along the coastline of the western Eyre Peninsula region during a reconnaissance survey of potential fossil strandline and foredune trapsites looking for economic heavy mineral sand...

Proterozoic basement outcrops consist of syn and post- Kimban Orogeny granitoids, volcanics and basic dykes. Their rock type geochronology, field relationships and regional correlation are reported. Previous economic mineral investigations, plus...

The LINCOLN 1:250,000 scale regional geological map area covers southern Eyre Peninsula and includes numerous islands lying off its eastern, southern and western coasts. The region encompasses a complex geological history and contains a variety of...
