Rare specs of gold were found at an old ochre mine next to the township of Oodla Wirra in remnant Tertiary and Recent alluvial deposits. Gold has also been recovered from a haematite vein in Adelaidean Umberatana Group rocks. Mining and sampling has...

A fundamental question remains to be answered in the Clare Valley. How much water can be safely extracted without causing depletion of the groundwater resources? This question is being addressed by a major investigation into the groundwater...

Phase Two of a drilling program at Clare, South Australia was undertaken in June, 1997. A total of 6 bores were drilled, 4 of these at existing locations established during Phase One drilling in January, 1996, and a further 2 at Watervale Oval as...

Contains summarised geological logs of 93 diamond drillholes and 4 percussion drillholes that were drilled by SADM/SADME and by exploration companies, including the logs of 2 early water bores drilled near Port Pirie. The holes penetrated Cambrian,...

Groundwater usage has increased substantially because of a change from dry-grown grape varieties to those needing irrigation. Regional dewatering caused by excessive extraction is unlikely because of the nature of the aquifers, but local usage...

Mineralization is widespread both geographically and stratigraphically, but many areas are under-explored. Past exploration was generally focussed on copper. Further investigation is recommended in the following units and areas: . Cambrian - Hawker...

Pre-Mesozoic rocks are best exposed in the Willouran Ranges SW of Marree, but inliers occur as far west as Stuart Creek. These approximate the junction of the Stuart Shelf (to the west) with the Torrens Hinge Zone, which extends east to the Norwest...

A small piercement structure east of Callanna station is an off-shoot from a major fault. The piercement cuts through steeply-dipping sandstone, siltstone and carbonate of the Tapley Hill Formation and Amberoona Formation and contains tectonic breccia...

The Torrens Hinge Zone Project aimed to demonstrate the existence of prospective metalliferous rocks beneath the Cainozoic cover, to stimulate exploration and to investigate the transition between the Adelaidean sequences of the well-exposed Adelaide...

As part of the SAEI (South Australian Exploration Initiative), thirty reverse circulation drill holes totalling 1123 m (av 37.4 m) were drilled on the Terowie 1:50 000 mapsheet area to determine bedrock geology and geochemistry below Quaternary cover,...

The Adelaide Geosyncline contains an extremely thick folded Late Proterozoic to Middle Cambrian sequence deposited initially in rifted troughs and later in broad zones of regional subsidence. Age constraints on deposition are based on dating of rare...

The Three Creeks EL 3567 covers, for the most part, the north-westerly plunging Yednalue Syncline. Lying to the south-east of the Worumba Anticline (a diapiric structure cored by disrupted Callanna Group), the syncline comprises Umberatana Group...

The subject report, drawing on numerous contemporary accounts, sketches and photographs of the historic Kapunda copper mine, clearly demonstrates that despite this mine being much smaller and earlier than the better-known 'monster' Burra mine, its...

Exploration for possible concealed porphyry style Cu-Au deposits of a kind similar to the nearby Blue Rose prospect surface skarn occurrence was undertaken over an area of the eastern Nackara Arc, 50 km south-east of Yunta. Work comprised inspection...

The original objectives of this project were: 1) To understand the processes responsible for transporting, concentrating and fixing copper and other ore constituents during sedimentary basin evolution 2) To document the various stages and paragenesis...

Copper mineralisation at the Mount Mary workings is restricted to a large E-W trending fault that emanates from the Blinman Diapir. Minor cross-shear fractures along this fault are filled by quartz-siderite veins that carry malachite plus some...

Exploration for a range of mineral commodities over relinquished parts of a licence area situated 80 km north-east of Orroroo has mainly targeted the Cainozoic to Mesozoic cover rocks for possible sedimentary gold, uranium, mineral sands and...

Subsequent to a partial relinquishment of ground and related data release made in August 2003, ongoing exploration conducted over a small area located about 25 km north-northwest of Manna Hill township, looking for possible Zambian type stratiform...

Exploration for possible economic gold deposits in an area located approximately 25 km south of Olary addressed three principal objectives: . hydrothermally-sourced gold within quartz-albite-dolomite vein stockworks formed in phyllitic siltstones of...

The banded iron formations associated with various tillite in South Australia have been recognised as being potential sources for iron however the low-grade nature of these bands has been one of the limiting factors in why they have not been...
