Dr. Jeff Steadman is a Postdoctoral Research Fellow in Geochemistry at CODES (Centre for Ore Deposit and Earth Sciences) in the College of Sciences and Engineering (CoSE). He currently specializes in the utilization of pyrite geochemistry as a vector towards concealed gold, silver, and copper ore bodies. His other geologic interests are metamorphic geology and impact processes.

Biography

Prior to joining CODES as a research fellow, Jeff completed his PhD there on the geochemistry of sedimentary-diagenetic pyrite in Neoarchean-Paleoproterozoic black shales, and whether these rocks are viable sources of Au in certain Au districts around the globe. Jeff also holds a Master's degree in Geology from Iowa State University (USA), during which time he studied a series of small base metal showings in high-grade Paleoproterozoic metamorphic rocks of the Wollaston Domain in northern Saskatchewan.

Research Themes

Jeff's research falls under the University's research theme of Environment, Resources and Sustainability. His current project aims to equip the mining and metals industry with better targeting tools for 'hard-to-find' orebodies (i.e., those under surficial cover, a common issue in mainland Australia). Over the last few decades, new discoveries of gold, copper, and zinc resources have declined, and the grade of known ore which is being mined continues to decline as well. To mitigate these looming issues and improve the sustainability of mining, new or re-vamped methods of exploration are needed to help geologists locate and mine those resources which are either not known or known but currently uneconomical to develop. One such method of exploration is using laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) to record and analyse the variation in trace element content of pyrite (FeS₂), the most common sulphide in Earth's crust. Because of its ubiquity, robust hardness (6/10 on the Mohs scale), and resistance to weathering, pyrite is an excellent candidate to use as a guide in mineral exploration. Pyrite crystals record hydrothermal fluid activity by scavenging certain trace metals (e.g., Co, Ni, As, Te, Cu, Hg, and Au) from said fluid and growing a new layer with each fluid pulse, in an analogous fashion to tree rings marking seasonal growth. As the concentration of these metals is commonly too low for normal assay techniques, the LA-ICPMS system is the preferred method for ascertaining not only which elements are present in a given pyrite but how much (down to ppb, or parts per billion, levels) of each element is there.

Through multiple case studies, Jeff's research demonstrates the value of pyrite geochemistry as a must-have tool for any serious explorer.

Collaboration

Jeff is teaming up with researchers from the University of Western Australia to map variations in S isotope compositions of various sulphides associated with ore deposits, in an analogous form to the trace element mapping that he and his colleagues have done and continue to do at CODES using LA-ICPMS technology. He is also collaborating with researchers at Curtin University in Perth, WA, on age dating Archean black shales using Re-Os techniques on carbonaceous matter.

Projects

Iron oxide copper-gold deposits: Geochemistry and Geometallurgy (2022 - 2024)$643,333

Description: Demand for Cu continues to increase as governments and corporations around the world increasingly invest in non-carbon-based forms of energy and transportation, such as wind turbines and electric vehicles. This places greater pressure on mining companies to find new Tier 1 resources. Mining companies that explore for Cu and other base or precious metals are increasing spending on deeper drilling campaigns targeted by ever more sophisticated geochemical, geophysical, and geostatistical techniques. However, new discoveries of Tier 1 Cu resources are occurring less frequently today than in previous generations, and the increase in exploration expenditure has not led to a direct increase in the number of discoveries (Fig. 1).

Mineral chemistry research proposal for Battery Minerals (2022 - 2023)$18,504

Description: This proposed research will study pyrite geochemistry to determine the genesis of the pyrite in auriferous siltstone from the Cox's Find prospect in western Victoria and to investigate the gold deportment in the siltstone Sample will be provided by Battery Minerals and will be analysed at the University of Tasmania. Specific research questions that will be addressed are: Within gold-bearing samples from the deposit: owhat is the mineralisation history of the deposit?owhere is the gold? What form is it in? What mineral is it associated with?oCan pyrite chemistry be useful for mineral exploration in the Stawell area in western Victoria?

Ore deposits and Tectonics of SE Australia: Freeport-McMoRan (2019)$30,000

Description: This project will test and improve the techniques developed by the ARC-funded Linkage project LP160100483 (Ore deposits and tectonic evolution of the Lachlan Orogen, SE Australia). Both the existing Linkage and this new project aim to identify prospective areas for hydrothermal ore deposits in SE Australia through combining mineral chemistry with large-scale plate tectonic reconstructions. The existing Linkage project has acquired a large amount of geochronological and geochemical data on approximately 1500 samples throughout the Lachlan Orogen and developed a new prospectivity model for SE Australia using G-plates software. This new project will extend the data collection and fund a new phase of modelling that will benefit both the existing Linkage project Partners and Freeport-McMoRan.

Evaluating epidote and chlorite mineral chemistry in the Temora area, NSW (2019 - 2020)$50,000

Description: Epidote and chlorite are important alteration minerals in porphyry and epithermal environments that record the chemistry of hydrothermal ore-forming fluids. This project aims to utilize chlorite and epidote trace element geochemistry to help locate potential Cu-Au-Mo porphyry targets in the Temora area, NSW.

Mineral Geochemistry Vectoring uncovering North West Queensland's hidden potential (2018 - 2020)$1,168,600

Description: The Paleo- to Mesoproterozoic Mount Isa district, Northwest Queensland, anchors the Northwest Queensland Mineral Province, one of the preeminent mining districts of the world. Many of the mines of the Mount Isa district are approaching end-of-life scenarios, which could have a significant negative socio-economic impact on the region. Finding new resources and re-vitalizing the Northwest Queensland Mineral Province is therefore of paramount importance.

South Australia Pyrite, hematite and magnetite Fingerprint Database (2014 - 2017)$204,000

Description: The project aims to produce a database and associated interrogative software package that provides a chemical fingerprint for pyrite, hematite and magnetite of various mineral and ore associations in selected districts of the South Australia. CODES has pioneered quantitative trace element analyses and micro-mapping of pyrite and magnetite by LA-ICPMS, involving several AMIRA projects and multi-client projects with industry. The technique is now being applied in mineral exploration and mine feasibility studies by several mining and exploration companies. This project will apply the technique to fingerprinting the multi element composition of pyrite, hematite and magnetite in selected South Australian samples. Up to 1000 pyrite, hematite and magnetite analyses, will be taken from mineralised and barren rock types, with at least 35 trace elements (including Pb isotope ratios) measured and quantified per sample. The resultant database will enable fingerprinting of pyrite, hematite and magnetite from a range of ore deposits and barren environments within South Australia. Key elements in these three minerals will be developed as halo and vector tools. Exploration companies will be able to use the database, in conjunction with their own pyrite, hematite and magnetite data, to place priorities on pyrite, hematite and magnetite alteration and mineralisation intersected in exploration drill holes.

Peak Gold Project (2014 - 2015)$37,970

Description: This study will test whether the observations of high gold content in pyrite extends to other basins and, if so, whether this can be used to discover new ore deposits or new mining districts. This is a controversial project that is based on a new concept of the genesis of gold deposits recently published. The outcomes will aid the exploration community greatly as, if proven effective, it will yield a novel tool for early stage exploration target generation.
