[ Note - here is Part 1 of the abstract relating to 2 separately indexed parts ]. As an adjunct to its widespread search for possible diamondiferous kimberlite diatremes on its Abminga Project acreage situated nearby to the north-west, Caldera...

Sampling of a thin, gently dipping quartz pebble conglomerate in the Mount Kingston - Peake area (13 samples totalling 3400 kg) gave Au values ranging from 0 - 0.036 g/t (mean value 0.015 g/t). Five samples taken for testing from two other areas...

TARGET: Diamondiferous kimberlites in the Boorthanna Trough region (near Nilpinna Springs). EXPLORATION: A literature review, the reprocessing and re-interpretation of data from BHP's 1983 Peake Creek Aerial Magnetic Survey flown by Aerodata /...

TARGET: Possible diamonds and source diamondiferous kimberlites in the Boorthanna Trough region. EXPLORATION: Present-day drainage heavy mineral sampling for kimberlitic indicators, follow-up barrage sampling for diamonds, an aerial magnetic survey...

Possible alluvial placer deposits of diamonds formed within the conglomeratic Early Jurassic Algebuckina Sandstone were sought in the Mount Anna district, as part of a wider search conducted across three adjoining ELs. Work on EL 1640 consisted of a...

Evaluation of the diamond potential of the Arckaringa area, 50 km south-west of Oodnadatta, which is here considered to be a region both tectonically and geologically favourable for the past emplacement of kimberlitic intrusive bodies, has comprised...

TARGET: Coal in the Arckaringa Basin. EXPLORATION: Rotary drilling (248 holes totalling 56,498 m, including 59 partly cored holes totalling 3555 m. RESULTS: The Wintinna, East Wintinna, Westfield and Murloocoppie coal deposits were discovered and...

Possible economic epithermal/hydrothermal uranium and base metal deposits hosted by Early to Middle Proterozoic meta-igneous and metasedimentary basement rocks in the northern Peake and Denison Ranges were the primary targets addressed by CRA in their...

Exploration for possible buried Olympic Dam (Cu-Au-U) style mineralisation, undertaken in the Welbourn Hill area by Newmont Australia Limited through its subsidiary Newcrest Mining, initially comprised the acquisition of ground magnetic, gravity and...

TARGET: Diamonds. EXPLORATION: Drilling (1 rotary hole totalling 306 m) over a possible buried kimberlitic diatreme identified from seismic and gravity surveys. RESULTS: No kimberlite was intersected.

Over the report period Agip Australia completed the drilling and geophysical logging of 39 open rotary holes totalling 3845 m to investigate if economic coal seams occur within Permian sediments of the southern Arckaringa Basin. Although the Permian...

Diamond exploration undertaken in the Peake and Denison Ranges included the acquisition and processing of aerial magnetic, radiometric and heliborne magnetic and VLF-EM surveys, with follow-up ground magnetic and Sirotem surveys, plus extensive...

The dispersed organic matter content of drill cuttings samples from the subject wells was examined microscopically to assess its hydrocarbon potential. In general it appears that the Cretaceous and Permian sediments are unlikely to be good source...

The Purni, Peera Peera and Poolowanna Formations were evaluated in terms of depositional and structural basin analysis using the model of Genetic Increments of strata (GIS). Eight reservoir intervals have been identified and the pertinent reservoir...

Potential mature source rocks occur in the Poolowanna Formation, the Peera Peera Formation and the upper part of the Walkandi Formation. In addition, marginally mature potential source rocks with fair to moderate TOC may be present in the lower half...

An assessment of the petroleum potential of the Pedirka farmout area, occasioned by the February 1989 compulsory 25% acreage relinquishment of PELs 5 and 6. Items reviewed include Block geology, farmout arrangements, future commitments, an inventory...

AIM:The 1982 Christmas Creek Seismic Survey was designed to cover a wide area of the sparsely explored western farmout blocks of PELs 5 and 6, where Eromanga Basin sediments thin and overly sub-basins of variously aged prospective sediments. Primary...

Sixty five samples from 4 wells were examined for organic matter type and abundance, and maturation levels. The Late Permian Purni and Early Jurassic Poolowanna Formations contain the best source rocks in the Poolowanna Trough. These sequences are...

A review of the Permo-Triassic and Mesozoic distribution of reservoir units. Data for some Birdsville Track Ridge wells are included as the development of the Pedirka Sector basins and the Birdsville Track Ridge are closely related.
