Investigations included drilling in the eastern part of EL 41, costeaning and close space drilling near Nob Well and Apollonaris anomaly, water well sampling, and ground search for carnotite.

In early 1991, Blinman 2 wildcat drilled through 2031 metres of sediments of the late Adelaidean Umberatana Group on the flank of the Blinman Diapir. Three small methane shows occurred in fracture zones in the Tapley Hill Formation.Two potential...

In the central Flinders Ranges, Neoproterozoic and early Palaeozoic rocks are found outcropping within a series of broad, open, dome and basin-shaped folds. This region contains most of the diapiric structures in the Adelaide Geosyncline, many, but...

Modelling and interpretation of gravity data newly acquired in the vicinity of the mapped anticline at Willippa indicate that the main gravity low is offset to the east from the crestal location of Willippa 1 well by some 4 km, and so is probably...

Report presents a consultant's independent assessment of the petroleum potential and risked prospect status for PEL 41, using data provided by the licensee.

A Frontier Exploration internal memorandum in which Professor Rudd expounds his interpretation of, and seeks discussion on, the apparently unique geological conditions which exist in the Central Flinders Zone and are related to the testing of the...

A low amplitude negative gravity anomaly occurring close to the centre of the Willippa anticline, and previously surveyed in some detail by MESA, has been modelled and interpreted by a geophysical consultant to Frontier Exploration Ltd in order to...

Preliminary modelling of regional gravity data for the Willippa Dome has been performed along three profiles across the structure, calculated in two dimensions only and neglecting any background regional gradient and terrain effects. Estimates have...

During the remapping of the Willippa Anticline by Frontier Exploration Ltd a number of copper bearing gossans were located within the outcrop of Burra Group strata on the crest of the structure. The main gossan, which outcrops just to the north-west...

Three advanced methods of depth-to-magnetic basement analysis were applied to BMR/SADME aeromagnetic data for the PARACHILNA 1:250,000 sheet: spectral analysis of grids, automated Naudy depth estimation, and forward modelling on profiles of flight...

A synopsis of the possible pre-tectonic structural setting and sequence of geological events which has resulted in the observed development of faulted domes and diapirs within Neoproterozoic sediments of the central Flinders Ranges, and the related...

This review article briefly addresses the structural patterns and tectonic history of the Central Flinders Zone of the Adelaide Geosyncline, as largely determined by the nature of the Delamerian Orogeny across this region. Comparisons with the...

Since 1990 Frontier Exploration Ltd has explored in the Central Flinders Zone of the Adelaide Geosyncline in order to assess its hydrocarbon and mineral potential, and the relationship of diapirs to these resources. The basic concepts used have not...

This paper synthesizes the findings of Frontier's exploratory efforts over the past three years, and makes recommendations for an ongoing exploration programme following and consequent to the economically unsuccessful outcome of drilling Blinman nos 1...

PEL 41 was granted to a deliberately SA-based new venture exploration company consisting of Chairman and well-known Emeritus Professor of Geology Eric Rudd, four other founding honorary and unsalaried directors, and 100 or so individual speculative...
