A sample of carbonaceous mud was assigned a Middle Eocene age. The date also provides maximum age for the silcrete which indurates the upper part of the formation in the creek.

Seven samples of lignite and carbonaceous clay were assigned a latest Middle to Late Eocene age.

Five claystone samples were assigned an Early Cretaceous (Early to Middle Aptian) age.

4 samples of drill core from a groundwater investigation well located approximately 6.5 km north-west of Mundulla were examined palaentologically to evaluate whether the Tertiary Murray Basin sediments that were cored can be correlated with similar...

SADME stratigraphic drillhole Ruby Hill 1 was sited 10.4 km east of William Creek, and was designed to penetrate Early Cretaceous rocks of the Eromanga Basin and to sample pre-Mesozoic basement. It intersected 191 m of the Eromanga Basin sedimentary...

Palynofloras from an outlier of North Maslin Sands are Middle Eocene in age. The palynofloras are non-marine and correlate with the Lower Nothofagidites asperus Zone of the Gippsland Basin and the 'Proteacidites pachypolus' Zone of south-central...

Limestone in which a rare fossil whale tooth had been found was dated.

All 4 rotary mud drill cuttings samples examined from parts of the precollar hole depth interval 64 m to 148 m are Late Eocene - Oligocene in age.

Palynological evidence indicates that all 13 submitted drill core sedimentary rock samples, excepting one (taken at 138.2 metres depth in hole A68-1), are late Aptian to earliest Albian in age. The sediments were deposited in environments ranging...

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...

A renewed effort to determine the diamond mineral potential of the 15.6 square km of land comprising Flinders Island was instigated during January 1999, under tenure of EL 2577, by Orogenic Exploration Pty Ltd, a company related to the previous...

Work undertaken on EL 4378 during the 2009-2010 reporting year included the drilling of 478 vertical rotary mud holes totalling 132,960 m, and core drilling totalling 4117 m performed in 16 of these holes for stratigraphic unit / resource...

During the 2008-2009 licence year, most of the new work done consisted of appraisal rotary mud drilling at Four Mile East (112 holes for 24,460 m) and Four Mile West (113 holes for 19,120 m), with the addition of one NQ diamond cored hole (AKC093) for...

An airborne scintillometer reconnaissance with ground-based follow-up, a geochemical study of groundwater, and open-hole rotary mud drilling (10 vertical holes, total 3205 feet) plus downhole wireline geophysical logging failed to locate significant...

Boorthanna 1 was drilled as a combined mineral/petroleum exploration hole and stratigraphic test in the southern section of the Boorthanna Trough, 29 km west of William Creek township, to: (1) penetrate the Devonian section in the search of potash...

The Abminga Diamond Project, undertaken by Caldera Resources NL, was granted exploration project status, including permission for EL joint reporting, in July 1996. This event followed up to two years of work by other operators on a number of...

In a search for possible economic roll-front, blanket style uranium deposits within Tertiary sediments in part of the eastern Frome Embayment, the licensee undertook 1:75,000 scale geological mapping and exploratory auger drilling of the Quaternary...

Development of the Prominent Hill copper-gold deposit in the Mount Woods region will require an adequate source of water to support planned mining and ore processing operations, currently estimated to involve at least 6 million tonnes of ore per year....

An area comprised of three separate sub-blocks generally located ~60 km south of Manna Hill and ~70 km south-southeast of Olary has been explored for Tertiary sedimentary uranium which may have formed in buried north to south trending palaeochannels...

An area located just to the east of the edge of the Nullarbor Plain, occupied by many scattered large and small salt lakes surrounded by sand dunes, with Precambrian basement [of the western Gawler Craton] subcropping near the surface, has been...
