  • Australian Mining History Association (Charters Towers July 2014): Offshore resource potential is clear with strong prospects identified, international certainty of tenure exists through the United Nations Convention on the Law of the Sea and the regulatory/legal system is well established, yet future offshore mineral prospects remains elusive. Deep sea mining's blue sky potential has been spruiked for so long it genuinely qualifies as mining history, but remains limited to future prospects. Historical targets have included diamonds, polymetallic nodules, cobalt on seamounts, base and precious metal rich hydrothermal vents, construction materials, coal and deep leads of tin or gold extending from onshore areas. Australia's seabed jurisdiction under the United Nations Convention on the Law of the Sea (UNCLOS) is over 16 million square kilometres, twice the area of Australian land. The Commonwealth Offshore Minerals Act 1994 relates to the exploration and production of these commodities, but in contrast to the offshore petroleum sector little activity has been recorded. Offshore resource potential is clear with strong prospects identified, international certainty of tenure exists through UNCLOS and the regulatory/legal system is well established, yet future offshore mineral prospects remains elusive. This is despite Australia based companies engaging in exploration and proposing developments in the South Pacific. Having identified the problem of lack of commercial interest, could government take actions to rectify the situation and encourage positive economic outcomes stemming from sustainable and environmentally responsible resource development in Australia's world scale offshore regime

  • The Value of Earth Observations from Space to Australia report (2015, ACIL Allen Consulting) examines the use of Earth observations from space (EOS) in seven key application areas: weather forecasting; ocean observation; monitoring land use and landscape change; agriculture; water; natural hazards and insurance; and onshore mining. Through a series of detailed case studies, the report establishes the value of the contribution of EOS in each application area and to the Australian economy as a whole.

  • The Mineral Potential Mapper (MPM) project represents a significant step forward in identifying new mineral provinces in Australia. The project demonstrated that the apparent under-representation of giant Ni Cu-PGE sulfide resources in Australia was a consequence of concealment of mineral deposits by sediments, basins and regolith (cover) which has hindered exploration success, rather than a lack of geological endowment. The project focused on the identification of prospective regions considered worthy of more detailed work (by exploration companies). The availability of new digital datasets at continental scale enabled the work which predicted a high potential for Ni-Cu-PGE sulfide deposits in a wide range of geological regions across Australia. The project delivered the following outputs: – a technical report providing the first continental-scale assessment of Ni-Cu-PGE mineral potential of Australia applying knowledge-driven geographic information system (GIS)-based prospectivity analysis methods – a series of Geodatabase digital maps (included in the report) – primary digital data and programming script used in the GIS analysis – a workshop delivered in Perth to industry on the 12 June 2016 – a world first National mineral potential map for Ni Cu-PGE sulfide deposits. The MPM materials have generated considerable industry interest. Chalice Mining Limited (Chalice) (formerly Chalice Gold Mines Limited) notes the MPM “… provided valuable input into Chalice’s regional targeting, particularly when applied to frontier areas” (and that) “… recent success at Julimar validates the work by Geoscience Australia (GA) and shows the impact that pre-competitive data can have when applied to greenfields exploration.” Chalice’s Julimar discovery is the world’s largest deposit of its type discovered in 20 years and one of four Tier one deposits discovered in the world in the last five years. It has spurred a significant uptake in tenements by explorers across a green field region and further significant finds are likely. The project has also generated considerable international government interest, sparking the Critical Minerals Mapping Initiative. The United States of America and Canada are both applying similar innovative mineral systems-based assessment methodologies to undertake precompetitive prospectivity mapping at a national scale. Given the impact of the MPM project will only be fully appreciated with the realisation of new mines, ACIL Allen has considered two hypothetical mine development scenarios: development of the Gonneville deposit based on Chalice’s (Australian Securities Exchange) ASX report of 8 July 2022, and a second case with an expansion of the Gonneville deposit (to 500Mt), coupled with a more spectacular discovery (double the size of the Gonneville deposit). Both success case scenarios were modelled using a conservative set of assumptions drawn from Chalice’s ASX reporting, prevailing market figures and industry norms. Based on those assumptions, ACIL Allen estimates that the development scenarios could generate an overall benefit to the Australian economy of between $3.48 billion and $4.57 billion and between $1.21 billion and $1.56 billion in net benefits to the Commonwealth in terms of taxation. GA’s investment in the project ($3.0 million) enabled the creation of these benefits. Indeed, every dollar invested in this project by the Commonwealth through GA could generate between $1,176 and $1,546 in additional benefits to the economy. The estimated benefit-cost ratio (BCR) for the Commonwealth Government is between 409 and 526 for the ‘success cases’. This is a substantial step up from the initial assessment conduct 12 months ago prior to the availability of resource figures for the Gonneville deposit (with a small and a large mine delivering an overall benefit of between $441 million and $869 million, with a BCR between 65 and 127).

  • Geoscience Australia, CSIRO, and the Australian Space Agency collaboratively developed a 2-page A4 flyer to promote education and careers in space to students and teachers. The flyer showcases Australia's unique capability in the space sector, far beyond astronomers and astronauts. It also lists QR codes of several Australian educational resources on a diversity of space topics for preschoolers through to university students. It is designed to be shared virtually or in person with stakeholders interested in promoting space science literacy and careers.

  • The Australian Government, through the National Water Infrastructure Fund – Expansion, commissioned Geoscience Australia (GA) to undertake the project ‘Assessing the Status of Groundwater in the Great Artesian Basin’ (GAB). The project commenced in July 2019 and will finish in June 2022. The aim of the project is to develop and evaluate new tools and techniques to assess the status of GAB groundwater system to support responsible management of basin water resources. A critical relationship exists between sediment depositional architecture and groundwater flow within and between GAB aquifers, and their connectivity with underlying and overlying aquifers. Little is known about lateral and vertical facies variation within the hydrogeological units and potential compartmentalisation and connectivity across the GAB. To improve the understanding of distribution and characteristics of Jurassic and Cretaceous sediments across the Eromanga/Galilee/Surat basins region, GA is compiling, processing and correlating a variety of well log data. Correlations have been made between geological units of similar age using palynological data from 322 key wells along 28 regional transects to standardise lithostratigraphic units, which are currently described using varying nomenclature, to a single chronostratigraphic chart across the entire GAB. The distribution of generalised sand/shale ratios calculated for 236 wells in the Surat and Eromanga basins are used to estimate the thickness of sand and shale in the different formations, with implications for formation porosity and the hydraulic properties of aquifers and aquitards. This study highlights regional lithological heterogeneity in each hydrogeological unit, and contributes to our understanding of connectivity within and between aquifers. This report and associated data package provide a first phase of data compilation on 322 key wells in the Surat and Eromanga basins to assist in updating the geological framework for the GAB. A data gap analysis and recommendations for building on this initial work are also provided.
