Drilling (132.8 metres) included fully cored geotechnical hole to basement to estimate mine planning constraints for open cut mining. The unconfined aquifer above the lignite must be dewatered for mine slope stability. Overburden contains 2 layers of...

Coal seam thickness averages 9.55 metres. In situ reserves are 8.85 MT. Recoverable coal reserves are 8.6 MT. Capital required to bring the mine into operation is $15.2 M. The real average cost of production is $13.69 / T.

Copper and gold mineralisation associated with felsic, intermediate and mafic igneous intrusive rocks which have intruded Adelaidean and Cambrian metasediments in the Nackara Arc region has been the target of exploratory drilling conducted with the...

During Dampier's exploration conducted near Morgan township in the western Murray Basin, the main target was possible economic coal measures in Cretaceous or Tertiary sediments, with the base metal potential of pre-Mesozoic basement rocks constituting...

An open hole rotary mud drilling programme of 42 holes for 4939 m was used to evaluate the licence area for economic Tertiary fluvial sandstone - type uranium mineralisation, after previous and current explorers had identified buried uraniferous...

This publication details the stratigraphy of the Murray Basin Province of South Australia. The work leading up to this report has played a major part in the understanding of the sedimentary succession of this important basin-area of the State. The...

The Transmissivity of the Murray-Glenelg Group Limestone aquifer at Wanbi, 150km east of Adelaide, is 200 metres3/day/m. A specific yield of 2.5 x 10-3 can be used for predicting the maximum effects of withdrawals, but is not considered a reliable...

The Murray Basin is an intracratonic basin filled with Cainozoic fluvial to shallow marine sediments. Deposition in the Eocene and early Oligocene was characterised by floodplain and swamp deposits, emplaced with occasional interbeds of shelly clays...

Stratigraphic drilling has been undertaken by PIRSA in the South Australian portion of the northern Murray Basin to investigate the stratigraphy and sedimentology of the Cainozoic sedimentary sequences, as well as the heavy mineral sand potential of...

Aquifer testing at two sites in the Qualco Sunlands Irrigation Area showed there is no detectable leakage between the Loxton Sands perched aquifer and the underlying Murray Group Limestone aquifer, provided that representative readings were obtained...

A five-layer finite difference groundwater flow model (MODFLOW) was developed for the Mallee Region to determine the impacts of irrigation on water levels and salinities. The model was calibrated for steady-state conditions over the entire modelled...

The contract drilling of three production wells, three combined interflow/production wells, three interflow wells, one observation well and seven drainage wells was carried out by Thompson Drilling Company as part of Stage 2 of the Qualco Sunlands...

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...

The Marne River is a main tributary catchment for the River Murray, which generates ephemeral flows in wet years. Concerns have been expressed at the construction of large dams in the headwaters of the catchment, about their impacts on streamflow,...

Previous investigations of the Late Tertiary Murray Basin shallow marine littoral zone clastic sedimentary sequence (Loxton and Parilla sands) for heavy mineral sand (HM) placer accumulations have discovered numerous occurrences of economic to...

Digging of exploratory shallow costeans into lithified Tertiary arenaceous sedimentary units on the eastern bank of the River Murray, 2 km south-west of Taylorville, to search for inferred workable deposits of decorative fossiliferous sandstone, did...
