The National Geochemical Survey of Australia (NGSA) is Australia’s first national-scale geochemical survey. It was delivered to the public on 30 June 2011, after almost five years of stakeholder engagement, strategic planning, sample collection, preparation and analysis, quality assurance/quality control, and preliminary data analytics. The project was comprehensively documented in seven initial open-file reports and six data and map sets, followed over the next decade by more than 70 well-cited scientific publications. This review compiles the body of work and knowledge that emanated from the project to-date as an indication of the impact the NGSA had over the decade 2011-2021. The geochemical fabric of Australia as never seen before has been revealed by the NGSA. This has spurred further research and stimulated the mineral exploration industry. This paper also critically looks at operational decisions taken at project time (2007-2011) that were good and perhaps – with the benefit of hindsight – not so good, with the intention of providing experiential advice for any future large-scale geochemical survey of Australia or elsewhere. Strengths of the NGSA included stakeholder engagement, holistic approach to a national survey, involvement of other geoscience agencies, collaboration on quality assurance with international partners, and targeted promotion of results. Weaknesses included gaining successful access to all parts of the nation, and management of sample processing in laboratories. <b>Citation:</b> Patrice de Caritat; The National Geochemical Survey of Australia: review and impact. <i>Geochemistry: Exploration, Environment, Analysis </i>2022;; 22 (4): geochem2022–032. doi: https://doi.org/10.1144/geochem2022-032 This article appears in multiple journals (Lyell Collection & GeoScienceWorld)

<p>The current coexistence framework for the Woomera Prohibited Area (WPA) was established in 2014; it seeks to balance the interests of all users in the Area. Under this framework, the Department of Defence is the primary user of the WPA for the testing of weaponry and related war materiels. Access to the WPA by a range of non-Defence users, including Aboriginal groups, the resources sector, pastoralists and tourists, is also provided for. The coexistence framework is being reviewed in August 2018. <p>As part of this 2018 WPA Review, Geoscience Australia, together with the Office of the Chief Economist, has undertaken the following tasks: <p>• Updated the current understanding of the region’s geology; <p>• assessed the known Economic Demonstrated Resources (EDR) and potentially undiscovered mineral and petroleum resources (including critical commodities) and groundwater; <p>• documented resource exploration activities in the WPA; and <p>• provided an economic assessment of the known mineral resources and possible future mine developments in the WPA. <p>An assessment of the potential for undiscovered mineral and petroleum resources has been conducted by considering the results of Geoscience Australia’s 2010 WPA assessment and by updating those findings as far as practicable within the available time of the present Review. Overall, this assessment confirms the results of the 2010 assessment and shows that many parts of the WPA have moderate to high potential for the discovery of new mineral and petroleum resources. Analysis of new data by this 2018 assessment has also identified additional areas with potential for groundwater resources in the WPA. <p>There is high potential for the discovery of new deposits, similar to those already known, especially of copper, gold, silver, iron, titanium and zirconium and uranium. Some of these deposits may contain economic REE and other critical commodities. <p>Modelling of the economic impact of possible new mine developments was carried out for high-value commodities with high potential for discovery in the WPA. The commodities included in the possible future mine scenarios are gold, copper, silver, uranium, iron, titanium and zirconium. Two scenarios were modelled, conservative and optimistic. <p>The Net Present Value of Economic Demonstrated Resources in the WPA is estimated to be $5.9 billion. The Net Present Value of possible future mines in the WPA is estimated to be between $6.4 billion and $19 billion. Annual direct employment across the future possible mines ranges from 150 people to 1350 people per mine, with secondary employment between 70 people and 1250 people. Annual value add across the future possible mines ranges between $8 million per mine to $920 million per mine.

The Australian Resource Reviews are periodic national assessments of individual mineral commodities. The reviews include evaluations of short-term and long-term trends for each mineral resource, world rankings, production data, significant exploration results and an overview of mining industry developments.

Australia's Identified Mineral Resources is an annual national assessment that takes a long-term view of Australian mineral resources likely to be available for mining. The assessment also includes evaluations of long-term trends in mineral resources, world rankings, summaries of significant exploration results and brief reviews of mining industry developments.
