10 March 2021 - SGEG Facets of Exploration Webinar
Speaker: Caroline Perring (Principal Geologist, BHP’s WA Iron Ore Division
Topic: South Flank: Anatomy of a BIF-hosted Martite-Goethite Ore System from the Hamersley Basin
WST: 12.00pm – 1.00pm (WA)
AEST: 2.00pm - 3.00pm (QLD)
ACST: 1.30pm - 2.30pm (NT)

AEDT: 3.00pm - 4.00pm (ACT, NSW, TAS, VIC)
Abstract: South Flank is BHP Western Australian Iron Ore’s exciting new mining development in the Hamersley Province of Western Australia. Development of this >1.9 Gt resource began in 2018 with the first ore scheduled for 2021 and an expected mine life of over 25 years.This talk will discuss a proposed new model for the genesis of supergene, martite-goethite, BIF-hosted mineralisation. The model was developed using exploration drilling data, 2D geophysical datasets, 3D modelling and ore petrography to understand the controls on ore development from the camp- to the grain-scale. A fluid and mass flux model is proposed which envisages a three stage process.
• Leaching of Fe from BIF in the vadose zone by reduced, acidic, meteoric-derived fluids.
• Penetration of a Fe-rich supergene-fluid plume, driven by gravity and focussed by bedding-parallel permeability, effecting non-redox mimetic replacement of magnetite by hematite and of the gangue minerals (carbonate, silicate and chert) by goethite and coupled with the release of silica into the fluid phase.
• A change from silica leaching to possible silica deposition on the down-dip margins of the system, before the ore-fluid plume is eventually diluted and becomes indistinguishable from the surrounding body of groundwater.
This process produces a distinct compositional zonation. At the grain-scale, the mineralisation appears to take place in three stages with a fourth stage represented by the lateritic weathering overprint. Three different textural types of goethite are identified at South Flank and have distinct positions in the paragenetic sequence. They are tentatively interpreted as ochreous, brown and vitreous goethite. These goethite types have distinctly different chemical and physical characteristics and behave differently during downstream processing, from the crushing and transporting phases through to sintering and smelting. An understanding of ore genesis thus provides a critical first stage in the exploration for and development of high-grade, direct-shipping iron ore deposits.
Biography: Caroline Perring was educated at Cambridge University and the Royal School of Mines, but has spent most of her career working in the Archaean Yilgarn craton of Western Australia. She completed a PhD at the University of Western Australia in the field of mesothermal Au mineralisation, before joining the Commonwealth Scientific Research Organisation to work with the Magmatic Ore Deposits group. Apart from a brief stint at James Cook University, working on Fe-oxide Cu-Au deposits, she spent the next 25 years studying magmatic Ni-Cu sulphide mineralisation and komatiite volcanism, latterly with Western Mining Corporation and then BHP Billiton Nickel West. She is now a Principal Geologist with BHP’s WA Iron Ore division.

18 April 2021 - ACT Division at the Canberra and Region Heritage Festival
Details: During the 2021 ACT Heritage Festival in April, the GSA ACT Division will have a pop-up booth on Federation Mall near Parliament House to highlight the new ACT Fossil Emblem chosen last year by popular vote. The ACT Fossil Emblem is an early Silurian trilobite, Batocara michelli (425 Ma), obtained from a foundation drill core during the 1960s construction of the Treasury Building near the Australian National Library in the Parliamentary Triangle. The drill core is now part of Commonwealth Palaeontological Collection held at Geoscience Australia. The GSA event will have an activity where kids can paint their own plaster cast trilobite as a memento. During the World Heritage Day event there will also be walking tours along the nearby heritage-listed State Circle road cutting that features a spectacular angular unconformity between rock sequences of the Benambran and Tabberabberan Tectonic Cycles.
Time: 10.00am - 4.40pm
Location: Federation Mall, Parkes, ACT

13-15 September 2021 - Short Course - EPITHERMAL Au-Ag and PORPHYRY Cu-Au EXPLORATION
Presenters: Greg Corbett and Stuart Hayward
Details: This short course has been running since the early 1990’s, then with the late Terry Leach, as an introduction to exploration for epithermal Au-Ag and porphyry Cu-Au ore deposits - http://corbettgeology.com/short-course/ Two days of powerpoint lectures draw on over 40 years of Dr Corbett's work as an Exploration Consultant in over 40 countries. A third day held at the W B Clarke Geoscience Centre, Londonderry, studies drill core and Greg’s specimens of these ore types. Here, Stuart Hayward, an explorationist with similar Pacific rim experience to Greg, helps to teach field relationships (spot the mineral) using drill core and many of the same specimens as feature in the powerpoint presentation. Participants are provided with a draft of the new short course notes which proceed at snail’s pace towards publication, as a colour update with over 1000 rock photos of the earlier notes (Corbett and Leach, 1998, Economic Geology Special Publish 6). Contact email@example.com to be put on the priority list. GSA member students are subsidised.
