Round 12 Co-funded Exploration Drilling results
The government continues to support the quest for new resource discoveries across Western Australia through the latest round of the Exploration Incentive Scheme (EIS) Co-funded Exploration Drilling program.
The Minister for Mines and Petroleum, Bill Marmion, announced that 48 applicants were offered $5.17 million in Round 12 of the Co-funded Exploration Drilling program for projects to be drilled KUNUNURRA in 2016. Mr Marmion said the scheme was helping to underwrite Western Australia’s continued 30 17 prosperity. KIMBERLEY 27 29 ‘This is an important investment in the State’s future, particularly in the challenging financial environment faced by exploration companies. Heading into its eighth year, this highly competitive drilling program has resulted in major discoveries, with more being made every year,’ Mr Marmion said.

ENS incorporates business rules that facilitate the sorting of rock units in a chronostratigraphic sequence.

Gravity and magnetic study of the western Amadeus Basin Recently released Geological Survey of Western Australia (GSWA) Report 154 by C Foss and others, provides a geophysical study of the western Amadeus Basin using all available gravity and magnetic a) datasets. It was carried out by CSIRO as part of the broader scale COBRA (Central Oz Basins Resources Kiwirrkurra Assessment) project; a collaboration between CSIRO, Government Geological Surveys, and industry partners. This component of the project was funded by the Kintore Exploration Incentive Scheme (EIS).
The western Amadeus Basin, situated between the 24°
inferred edge of Arunta (north) and Musgrave (south) basement Amadeus Basin regions, and onlapped by the Canning Basin from the Kaltukatjara west (Fig. 1a), is a barely explored frontier area for (Docker River) petroleum and mineral resources. The basin as a whole b and c Warakurna is of early Neoproterozoic to late Paleozoic age, and contains oil and gas fields with Ordovician and late Neoproterozoic reservoirs in the Northern Territory. The NT Western Australian end of the basin, predominantly of 26° Neoproterozoic age, is poorly exposed and currently Warburton SA

Fieldnotes January 2016 7 3D Geomodel Series
Publication of the first GSWA 3D models
The first 3D geology digital packages (‘3D Geomodel Series’) number of prospective large igneous complexes within the Yilgarn were released to the public on 30 November 2015. They include to be modelled; applying the same techniques to many other a full representation of the area in three dimensions as well similar rock assemblages could vastly increase the exploration as the standard 2D digital data suite. All aspects of the model space for magmatic intrusion-related commodities such as nickel can be viewed with Geoscience Analyst, an easy-to-use free and copper. third-party viewing software that is included in the package. Also provided are the 3D contents of the package in widely The Sandstone model, which includes significant gold used file formats for import into the users’ own software. With deposits, explores the deep fault geometries across the the publication of three-dimensional geological models, the Northern Yilgarn Craton. Such structural models at the Geological Survey of Western Australia (GSWA) is enabling a scale of the Earth’s crust can image the architecture of a better understanding of the Earth’s structure, and an improved mineral system from ancient mantle-tapping fault zones to knowledge base to underpin exploration for mineral and energy resources.
Faults, fracture zones and shear zones can be pathways for fluids and melts within the solid Earth. The Earth’s 3D structure therefore not only reflects the distribution of physical properties of the rock mass in bedrock, sedimentary basins and regolith cover, but often relates very closely to the spatial distribution of mineral deposits and energy resources that formed as a consequence of fluid flow in the Earth’s crust. 3D structural modelling and numerical simulation of geological processes are emerging techniques that can be used to extend knowledge from exposed and well-understood areas to inaccessible or data-poor parts of the Earth’s crust and lithosphere, and to test the validity of conceptual models and interpretations.
The construction of 3D models utilizes the full spectrum of extensive geological mapping and geophysical (magnetic, gravity, deep seismic reflection) data acquired by GSWA as part of the Figure 1. Geological sections from the 1:100 000 map series and seismic interpretations which went into Exploration Incentive Scheme (EIS). Differences building the Windimurra model. Grey lines show the model faults. in the physical properties within the Earth allow inversion of the data to give property distributions from which boundaries can be inferred at depth. No geophysical dataset contains uniquely correct solutions when the question of depth versus density/ susceptibility/seismic velocity is concerned, but when all datasets are used in conjunction, the correlations increase and the ambiguity decreases. Modelling synthesizes these data into a product which simultaneously explores and unites the 3D information contained within each dataset.
The first two 3D Geomodel Series products released are the Windimurra, and the Sandstone models. These regions, located in the northern Yilgarn Craton, have known deposits of vanadium and gold. The models enhance exploration potential for more gold, platinum group elements, nickel, and copper.
At Windimurra in the Murchison Domain of the Yilgarn Craton, the 3D model predicts where ultramafic rocks, prospective for chrome and platinum group elements, may continue at depth Figure 2.

His ‘holistic view of the scope of the project boundaries’ led to him working on neighbouring Neoproterozoic successions, as well as discovering the first recorded gold mineralization at Quadrio Lake in the Little Sandy Desert. He transitioned seamlessly from the Phanerozoic to the Proterozoic. In 2007 Roger took up the mantle of Chief Geoscientist. In this role he utilized his broad-ranging experience of most of Western Australia’s basins to offer high-level advice and expertise to enhance understanding of the geological framework of Western Australia both within and outside GSWA, and was a mentor to many younger GSWA recruits. He also sought opportunities to promote the many outstanding geological features of Western Australia in the area of geotourism. After co-authoring the 1998 State map, he has been instrumental in bringing the next State map into the digital world of 2015; its release date serendipitously aligned with his date of commencement at GSWA. We wish Roger well in the new phase of his life. 10 Fieldnotes January 2016 Geophysical surveys GSWA regional geophysics KUNUNURRA surveys: December 2015 update BROOME The latest release of Geological Survey of Western Australia (GSWA) regional KARRATHA 2 geophysical surveys is the Ngururrpa gravity survey.
