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

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.

Mineral exploration ideally involves researching geological potential within the constraints of economic feasibility. Nevertheless, explicit consideration of economic factors is often delayed until late in the exploration cycle. This is not ideal. Like mineral prospectivity, projected economic feasibility can be used to refine the search space and thereby reduce the risks associated with mineral exploration undercover. Here, we outline an exploration strategy based on the notion of identifying economic fairways—that is, regions permissive to resource development from an economic perspective. The approach appraises the economics of Au, Cu, Ni, Pb, Zn, potash and phosphate deposits by modelling revenue against capital expenditure (such as the costs of employment, mining overburden and access to infrastructure). We demonstrate the economic fairways approach through regional assessment of a Tennant Creek–style iron oxide–copper–gold deposit across northern Australia. Our results indicate that such a mineral deposit is expected to be economically viable across much of northern Australia, including in areas with several hundreds of metres of overburden. Our analysis sheds light on the need for accurate cover thickness models, without which undercover economic fairways cannot be defined. Our online tool benefits mineral explorers, and also helps to inform investors about the relative strengths of potential mineral projects; policy makers could use it to plan regional infrastructure development in frontier mineral provinces. <b>Citation:</b> Haynes, M.W., Walsh, S.D.C., Czarnota, K., Northey, S.A. and Yellishetty, M., 2020.

<div><strong>Output type: </strong>Exploring for the Future Extended Abstract <strong> </strong></div><div><br></div><div><strong>Short abstract: </strong>There is an increased international focus on achieving high environmental, socio-economic, and governance (ESG) outcomes within mineral supply chains, in addition to delivering positive economic results. Mineral exploration and development projects must balance these disparate objectives to the satisfaction of separate stakeholders. However, the challenge of reconciling distinct preferences can obscure viable outcomes and confound project selection, particularly in the early stages of project development. Here, we discuss how such investment decisions can be treated as multicriteria optimization problems. In appraising the pre-competitive potential for nickel sulphide developments, we show how this approach can be used to effectively evaluate competing objectives and to locate regions that perform best under a range of different metrics. We outline a mapping framework that identifies Australian regions that optimally balance geological potential, economic value, and environmental impact. Our workflow creates a new capability within Australia to incorporate high-level, holistic information into the earliest stages of exploration. While this abstract focuses on mineral exploration, the modelling could be extended to other Australian resource development applications. Importantly, our results further underscore the need to compile baseline ESG datasets across Australia to help drive sustainable exploration decisions.</div><div><br></div><div><strong>Citation:</strong> Walsh S.D.C., Haynes M.W. &amp; Wang C., 2024.

<div>Mineral exploration and development involves the selection of potential projects which must be evaluated across disparate characteristics. However, the distinct metrics involved are typically difficult to reconcile (e.g. geological potential, environmental impact, jobs created, value generated, etc.). Separate stakeholders—with different goals and attitudes—will reasonably differ in their preferences as to which categories to prioritize and how much weight to give to each. These conflicting preferences can obscure optimal outcomes and confound project selection.</div><div><br></div><div>In this presentation, we will discuss how early-stage exploration decisions can be treated as multi-criteria optimization problems. We show how this approach can be used to effectively evaluate and communicate competing criteria, and locate regions that perform best under a range of different metrics. We then outline a mapping framework that identifies regions that perform best in terms of geological potential, economic value and environmental impact and demonstrate this approach in a real-word example that highlights new exploration targets in the Australian context.

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.
