INTRODUCTION TO THE GUIDE Northern Yorke Peninsula (NYP) is within the southern portion of the Olympic Domain of the eastern Gawler Craton, which is arguably the world’s most fertile IOCG belt. That such a belt existed was only realised when Western...

The community water supplies at Kalka, Mimili and Kenmore Park in recent times were insufficient for emergencies, while the wells at Amata were in poor condition. In this remedial work program, drilling of three new wells at Kalka has doubled the...

Calcrete sampling over aeromagnetic targets within the Fowler Shear Zone was undertaken to locate evidence of possible Cu-Au mineralisation, developed during emplacement of Hiltaba Suite granites south and south-west of Wynbring. Weakly anomalous Au...

Kimberlite-seeking loam sampling and soil geochemistry, undertaken in the vicinity of 28 selected magnetic targets distributed within eight separate licence areas extending from 150 km west-northwest of to 120 km north of Oodnadatta, only yielded a...

Sedimentary uranium orebodies within Tertiary palaeochannels were the target of exploration in the area of the Siccus River, south of Lake Frome. Extensive research into available open file past exploration data allowed the identification of both...

Reconnaissance, helicopter supported mapping and sampling within the Yellabinna Regional Reserve, 70 km north-northwest of Ceduna, revealed more extensive basement outcrop than previously recorded, but returned no anomalous metal values. Infill...

An airborne geophysical survey carried out over an area spanning the Stuart Highway environs, 60-80 km south of Marla, searching for possible buried outliers of the Musgrave Block, revealed a few weak uranium radiometric and inferred deep (> 400 m)...

Sedimentary uranium in Tertiary palaeochannels was the target of exploration in an area 90 km east of Lake Frome, adjacent to the NSW border. Work included research and compilation of open file drilling data, compilation of structural contour maps,...

A regional drilling programme was undertaken to investigate the economic potential of possible Permian coal occurrences within buried extensions to the Lake Phillipson Trough, in its adjacent northern Penrhyn Trough and south-eastern Ingomar regions...

Reconnaissance, helicopter-borne geological mapping and rock chip geochemical sampling were carried out within the Yellabinna Regional Reserve, 70 km northeast of Penong. No anomalies were identified, but the area retains considerable Cu-Au...

Ground magnetics and trial calcrete sampling were carried out over an aeromagnetic target within the Tallaringa Conservation Park, 100 km west of Coober Pedy. Interpreted depths to basement ranged from 100 to 300 metres, and no anomalous geochemistry...

Attempted exploration for gold and base metals within Archaean and Proterozoic rocks 200 km north-west of Ceduna has been frustrated by limitations to access arising under Aboriginal heritage and Native Title claim clearance procedures. Progress has...

Following initial assessment of available data, exploration for copper, gold and base metals in an area 60 km west of Tarcoola concentrated on regional calcrete sampling. Analysis for gold and a suite of base metals indicated several areas of...

The investigation embraced by this report was initiated as a special project under the direction of the Chief Geologist, with the object of assessing the oil prospects of the Cambrian rocks of Yorke Peninsula. Following a preliminary reconnaissance in...

An inability to negotiate Native Title approval for drilling access to the floor of Lake Torrens at Carrapateena Arm resulted in the licence being surrendered without technical work being undertaken.

As part of a search for possible concealed nickel-copper-cobalt sulphide mineralisation of Voisey Bay type buried within the Giles Complex at the eastern end of the Musgrave Ranges, Landsat and aeromagnetic interpretation of the mid-Proterozoic...

Base and precious metal exploration near Pinda Springs mine in the north-central Flinders Ranges, 50 km south-east of Copley, initially comprised geological mapping and rock chip sampling. Several vein samples returned values up to 1.2 kg/t Ag, 10.5%...

Exploration over the licence area was severely restricted due to its being located entirely within the Yellabinna Regional Reserve, and because of unresolved Native Title claims. Initially, acquisition of a detailed aeromagnetic survey, comprising...

Mafic and ultramafic rocks of the Proterozoic Giles Complex, which have intruded highly metamorphosed basement units of the Musgrave Block in an area 380 km WNW of Marla, were considered to have potential to host massive Ni sulphide mineralisation,...
