TRONA EXPLORATION: Of the 9 rotary/diamond holes drilled, only the first, Meramangye 1, intersected a unit equivalent to the Observatory Hill Beds, which was the target horizon for trona. Drillholes Manya nos 2-6 and Marla 7 intersected Cambrian red...

A process of rationalisation of several prior-held CRAE tenements covering Cambrian trough sediments which partly outcrop in the south-eastern Mount Lofty Ranges has led to limited ongoing exploration by that company. Ground-based follow-up of all...

Continuing intensive exploration for economic sedimentary uranium deposits within buried Tertiary palaeochannel sediments in the Yarramba Homestead area, 50 km north-west of Cockburn, which had been invigorated by the recent discovery of strongly...

Exploration for possible Alligator Rivers (Northern Territory) style uranium deposits occurring in potential host rocks (carbonaceous pelites and carbonate rocks) within an Early Proterozoic metasedimentary sequence underlying a Middle Proterozoic...

Exploration for Broken Hill or Aggeneys type Proterozoic stratiform base metal massive sulphides within the Hutchison Group in the Mount Shannan area, north of Cleve, has included the acquisition, processing and interpretation of airborne magnetic,...

Magnetic profiles above dyke feature indicate the eastern flank dips to the W. The northern area has very high gradient, large amplitude magnetic linears caused by 5 dipping haematite quartzite horizons in sequence of folds while the southern half has...

2130 miles of aeromagnetic and aerial radiometric traverses were flown at 300 feet altitude, with a half mile line spacing. Results are presented as TMI maps and stacked profiles of the uranium channel. There are numerous radiometric anomalies but no...

The exploration concept was based on searching for secondary uranium mineralisation that might be derived from the Musgrave Block basement rocks and that could have become precipitated within calcrete horizons from ponded uraniferous surface drainage...

Aeromagnetic, ground magnetic and EM surveys, with follow-up rock chip, stream sediment and soil sampling, RAB drilling (688 holes, total 17,553 m) and RC drilling (12 holes, total 1149 m), have defined an extensive zone of anomalous base metal...

Continuing exploration in the Woomera area has included the acquisition of a ground magnetic and gravity survey over the Buller Dam anomaly, which lies on the western flank of the Acropolis aeromagnetic anomaly, and this work confirmed that the former...

Initial exploration carried out near Lilydale Homestead, 80 kilometres south-east of Yunta, targeted possible Starra-style gold in the Braemar Ironstone facies. Flying of an airborne semi-detailed magnetic and radiometric survey identified magnetic...

Exploration for possible heavy mineral sand marine placer deposits within Tertiary sediments on the northern margin of the Murray Basin comprised aircore drilling (28 holes, total 744 m) in the Mutooroo station area, 50 km south-east of Olary. The...

To promote renewed regional exploration of the northern Yorke Peninsula using modern techniques and concepts, MESA as part of the SAEI programme has prepared a GIS-based data package, which incorporates a study of all available drillcore and a...

Exploration undertaken over an area located 60 km west of Port Augusta targeted possible Broken Hill or Aggeneys - Gamsberg type massive Pb-Zn deposits within Early Proterozoic Hutchison Group banded iron formation metasediments, and also any Early...

Exploration undertaken on ground situated east of Pernatty Lagoon has included the acquisition of extensive ground magnetic and gravity surveys plus a small aerial magnetic and radiometric survey, and performing many specific gravity and magnetic...

Interpretation of reprocessed BMR data and survey flown by Geoterrex Pty Ltd.

Exploration for Olympic Dam-style Cu-Au-U mineralisation, undertaken over areas to the south-east of Arcoona Homestead and in the vicinity of Woomera township, has comprised numerous reconnaissance and then detailed gravity, ground magnetic and CSAMT...

Base metal exploration activities undertaken by Thiess Brothers in the Yumali - Coomandook area investigated several coincident regional gravity and aeromagnetic anomalies arising from concealed Palaeozoic basement rocks. These anomalies are part of a...
