Diamond, gold and platinum group element (PGE) exploration activities carried out within an area of known kimberlitic and lamproitic intrusive rocks east of Elliston comprised aircore drilling (23 holes, total 1188 metres), addressing 17 out of 36...

Diamond and gold exploration undertaken on the two relinquished ground portions located north-west and east of Venus Bay on Eyre Peninsula, which total 530 square km in area, have comprised heavy mineral sampling, heavy mineral grain microprobing,...

Three of nine untested magnetic anomalies, identified by the reprocessing of company aeromagnetic data acquired over an area east of Elliston, were drilled as part of a regional search for buried diamondiferous kimberlites. The resulting three...

Shallow basement along basin margins, and intersections of structural lineaments with Hiltaba Suite granitoids, were targeted over three separate areas: 40 km north-east of Elliston, and 10 and 30 km respectively south and east of Lock. No significant...

Aircore drilling of gold and base metal targets (23 holes, total 1136 m) was undertaken following lag, rock chip and leach sampling and a review of previous aeromagnetic and drillhole data from three separate areas, 40 km west and 50 km north-west and...

Calcrete and rock chip sampling, the latter including outcrop follow-up of weakly anomalous Cu and As found in re-assayed drillcore, was carried out in the hinterland to Port Neill, 80 km north-east of Port Lincoln. Calcrete Au results peaked at only...

Lag/laterite geochemical sampling carried out 20 km west of Port Lincoln identified certain areas that are anomalous in As. However, no anomalous drillcore assay results were returned from follow-up aircore drilling (5 holes, total 281 m) of a...

Calcrete and stream sediment sampling plus a TEISA programme infill aeromagnetic survey were carried out over an area extending for 10-40 km to the north-west and north of Cowell. Anomalous Cu in calcrete was recorded in the vicinity of the Charleston...

During the past 15 years, a major investigation (553 Rb-Sr and 100 K-Ar analyses) were undertaken to determine the Archaean - Proterozoic stratigraphic, magmatic and tectonic history. The isotopic dates define 3 broad groupings, Sleafordian Orogeny (2...

This report presents the results of a study jointly conducted by the Geological Survey of South Australia and CSIRO Mineral Resources which aimed to enhance the expression of geological structure in geophysical images and to derive depth to magnetic...

The Gawler Province 3D Geological Model is the second product of PIRSA's early 3D modelling trials conducted using 3D GeoModeller software. The work began with identifying the statigraphic units that were to be modelled. Due to the regional scale of...

This report presents geochemical constraints on the evolution of the Minbrie Gneiss and Carpa Granite, two magmatic units occurring in the southern Gawler Craton. These two units were previously assigned to the Palaeoproterozoic Lincoln Complex,...

The Cultana basement 3D Geological Model covers a region which includes the Roopena, and western half of the Cultana, 1:100,000 mapsheet areas. The subsurface geology that has been modelled comprises a succession of deformed Palaeoproterozoic...

During the period 11 June 2018 to 6 August 2018, approximately 60% of the PORT AUGUSTA 1:250k map sheet area, that covers the far north-eastern portion of the Eyre Peninsula, was flown under contract to the SA Government and Geoscience Australia as...

This inaugural regolith map of the southern Gawler Ranges margin provides a valuable regional overview of the main regolith types and their associated landforms, plus a general outline of the major areas of bedrock or regolith-dominated terrain, as...

The western 138 square km of EL 4815 has recently been relinquished. No field work took place on this acreage. Only minor desktop investigations were carried out by Lincoln Minerals on the now relinquished ground, due to other project priorities, and...

A small area centred ~50 km west-southwest of Kimba has been explored for possible buried base metal mineralisation, including BIF type iron ore, and also for gold and perhaps palaeochannel style uranium, that may have formed within or close to...

In this article we present new EPMA monazite geochronological data from the deformed and metamorphosed Sleaford Complex units at Fishery Bay in the southern Gawler Craton. The results show that these fabrics formed during the development of the...

Following a review of previous company exploration and image interpretation of SAEI and BMR aeromagnetic data, a 3166 line km airborne magnetic/radiometric survey, with follow-up ground magnetics and air core drilling (282 holes, 4559 m), was carried...

Diamonds and base and precious metal exploration undertaken north-east of Port Kenny on western Eyre Peninsula comprised loam sampling for kimberlite indicator minerals, RC drilling (7 vertical holes, total 470 m), plus bedrock petrological, heavy...
