Mississippi Valley - style stratabound lead-zinc mineralisation in Lower Cambrian carbonate rocks, and unrelated possible diamonds ex- buried kimberlite, were the targets of exploration undertaken in the now relinquished Reaphook Hill subarea of EL...

Possible economic stratabound or epigenetic lead-zinc or copper deposits, formed in altered carbonate rocks lying marginal to the Wirrealpa Diapir, were the targets of new exploration centred on the area of the old Wirrealpa lead-silver mine....

81 closely-spaced rotary mud vertical open drillholes (total penetration 9218 m) evaluated known low grade palaeochannel uranium mineralisation previously detected in Miocene sand sequences adjacent to the Anabama - Redan Fault by Tricentrol Australia...

Tertiary age heavy mineral sand marine placer deposits were the principal target in the Naracoorte - Penola region. Following an assessment of regional geophysical data seeking to identify possible palaeo-depositional traps adjacent to basement...

An ongoing work programme has included the latter stages of: the drilling of over 180 percussion and diamond holes totalling 24,388 m, the collection and assaying of 35,000 geochemical samples, preparation of 1150 petrographic descriptions, and...

Metal sulphides occurring in dolomitic mud and silt facies (Sweet Nell type deposits) were probably deposited in a supratidal environment, where the dolomitic shale facies with Cu mineralization probably originated closer inshore, while Pb, Zn...

TARGET: Palaeo-alluvial diamonds in the Triassic Boolcunda Basin. EXPLORATION: Initial soil sampling and ground magnetic surveys of geochemical and geophysical anomalies; comprehensive regional and follow-up heavy mineral stream sediment sampling of...

TARGET: Possible economic heavy mineral sands accumulations that may have formed within the Early to Middle Pleistocene marginal marine sediments deposited around and behind basement shoals of the Padthaway Ridge. EXPLORATION: Reconnaissance reverse...

This EPP 26 surrender report has been furnished to the SA offshore Designated Authority as a result of the application made on 21/8/96 by BHP Petroleum for permission for the joint venture to surrender the permit, before committing to unwanted...

Analysis of Pliocene sedimentation along the Padthaway Ridge has identified a major shoreline feature in the Marmon Jabuk Range, with associated, but younger, shorelines developed in the Padthaway area. Traversing and sampling has established the...

This report is intended to be a convenient single reference to the Cattlegrid ore deposit geology. It represents an updated summary of a large amount of data, gleaned largely from internal company reports. The subject matter relates mainly to the...

AIM: The 1993 Troubridge Shoals Seismic Survey programme, of shallow water/shelf transition zone coverage on the southwestern and western sides of Gulf St Vincent, was designed to tie the extensive offshore seismic data of recent vintage to the...

TARGET: Now buried heavy mineral sands accumulations that may have formed within the Tertiary Parilla Sand as palaeo-beach placer deposits. EXPLORATION: Appraisal of SADME-held water bore data, photogeological studies, geomorphic mapping,...

TARGET: Possible economic heavy mineral sand accumulations in Pliocene raised beach strandlines developed along the south-western margin of the Murray Basin. EXPLORATION: Acquisition of an airborne magnetic and radiometric survey during November...

TARGET: Possible economic heavy mineral sands accumulations that may have formed in the Pliocene palaeocoastal dune and beach ridge sand sequence of the Marmon Jabuk Range, within an area extending south-eastwards from Tailem Bend for ~80 km.....

The heavy mineral potential of Tertiary sediments in the Chundie Swamps was investigated with 2 drill traverses (43 RC open vertical holes totalling 863 m) and reconnaissance soil mineralogical sampling. Heavy mineral contents were very low.

TARGET: In an untested area immediately west of Leigh Creek, extending as far as the eastern side of Lake Torrens, ETSA was aiming to find buried deposits of Late Palaeozoic or Mesozoic coal of a rank at least equal to that of Leigh Creek coal (and...

2 main types of copper deposit are recognized. 1 of these is of low grade, near the base of the laminite sequences in the Woocalla Dolomite, probably of syngenetic origin, and is believed to be the oldest and primary kind of deposit. (Gully, MG 14...

TARGET: Sulphides at Whyalla Sandstone - Pandurra Formation contact (Cattlegrid type), in Woocalla Dolomite (Sweet Nell type) and in black shale. EXPLORATION: Geological mapping at 1:30 000 scale, reconnaissance rock chip sampling, subsurface soil...
