Southern Geoscience Consultants, Principal Geophysicist Karen Gilgallon will present on, ‘Airborne EM for Integrated 3D Mapping of Groundwater, Seawater Intrusion and Relationship with Sustainable Yield in Exmouth, WA’ at the Australian Geoscience Council Convention 2018 on Wednesday, 17 October at 4:15pm in Room R5, Adelaide Convention Centre.
Exmouth, Western Australia is a regional centre that relies entirely on groundwater for its water supply. The current borefield extraction has insufficient capacity to meet increased water demand due to population growth and the influx of tourists in holiday periods. In 2016-2017, the Water Corporation decided to investigate optimizing borefield performance through improved production from existing infrastructure. An Airborne Electromagnetic (AEM) survey, desktop review, 3D modelling, and pumping tests, helped define the extent/geometry of the saltwater interface and karstic features within the aquifer. Importantly, bores have been identified which could accommodate additional sustainable extraction. Other bores have been identified where extraction rates should not be increased, or should be reduced.
Karen graduated from Curtin University of Technology BSc (Hons) in Geophysics, and has been interested in groundwater since completing her honours thesis on “Geophysical Signature of the Lake Bryde Paleochannel”. After graduating, Karen worked for the Waters and Rivers Commission (now the Department of Environment and Conservation) in the hydrogeology section to help explore for and monitor groundwater resources. Karen has worked with numerous geophysical methods exploring for various types of economic mineralisation, and groundwater. She has experience as a field-based supervisor for surveys in Australia, Africa and Papua New Guinea. As a Principal Geophysicist, she is responsible for the design, management, and interpretation of all types of geophysical surveys. Karen has particular experience in the QC, interpretation and modelling of electrical and electromagnetic methods.

Orion reported positive initial Fixed-Loop Electro-Magnetic (FLTEM) survey results over Ni-Cu targets on the Disawell prospecting right (Disawell) in the Areachap Belt, South Africa. Fixed-Loop Time Domain Electro Magnetic (FLTEM) surveys and geological mapping following up on helicopter-borne Electro Magnetic (SKYTEM) anomalies on the Namaqua – Disawell mineral rights commenced in May 2018 (refer ASX release 1 February 2018). Orion is targeting high-grade, magmatic intrusive sulphide Ni-Cu-Co-PGE mineralisation with similar geology and age of mineralisation as the Nova-Bollinger Mine, Fraser Range, Western Australia.
- Five compelling Ni-Cu-Co sulphide targets identified from Fixed-Loop Electro Magnetic surveys.
- Targets all lie within the Jacomynspan Ni-Cu-Co ultramafic intrusive cluster.
- The modelled high-priority target EM plates have far higher conductance than an orientation survey conducted over the known Jacomynspan Sulphide Mineral Resource of 6.8Mt at 0.57% Ni, 0.33% Cu and 0.03% Co.
- Plates are interpreted to lie within, or in close proximity to, ultramafic bodies with significant drill-confirmed Ni-Cu sulphide mineralisation.
- Diamond drill rig mobilising to test the EM plates.
SGC would like to commend Orion’s team on the continued exploration efforts and ongoing very encouraging results as outlined in their recent announcement:

Melbourne, VIC / February 1, 2018 / Orion Minerals NL (ASX/JSE: ORN) is pleased to provide an update on its regional exploration activities on the Areachap Belt in South Africa. A helicopter-borne magnetic and electromagnetic survey (AEM or SkyTEM) over the Masiqhame and Disawell prospecting permits was completed on 24 January 2018.
Preliminary results for magnetic and SkyTEM data have been received and reviewed. The survey succeeded in acquiring high quality data and initial indications are positive for the identification of priority follow-up targets. Once targets have been ranked, Orion intends to test for Zn-Cu rich volcanogenic massive sulfide (VMS) and Ni-Cu magmatic deposits.
The survey demonstrates the value of applying modern airborne EM methods in the highly prospective Areachap Belt. Numerous AEM anomalies were identified during a preliminary review of the data by Orion’s Perth based geophysical consultants, Southern Geoscience Consultants. In addition to the AEM data, the accompanying magnetic data will significantly improve our understanding of the geology and structure in this area of poor outcrop.
- A 962 sqkm high power SkyTEM airborne EM survey completed on 24 January 2018
- 6,018 line km of flights covering the survey area have been completed
- Numerous discrete anomalies appear in the preliminary data set
- AEM anomalies detected over known Zn-Cu VMS and Ni-Cu intrusive deposits
- A number of AEM anomalies coinciding with a paleo-seafloor, offer immediate follow-up targets

SGC has been working with Venturex on the acquisition, processing and interpretation of a new Xcite™ heliborne electromagnetic survey (“HEM”) which has identified 11 geophysical targets. The targets are interpreted as being associated with the Marker Chert horizon, the host of the Sulphur Springs VMS deposit, and/or the underlying felsic volcanic contact.
The HEM survey demonstrates the exceptional exploration potential of the Sulphur Springs project area. The results represent an exciting development for the project, with numerous high-priority targets generated that warrant further detailed field investigation, ground EM surveys and potential drill testing.

Modelling over a 10 km long magnetic anomaly at Centaurus Metals‘ Canga Iron Ore Prospect in Brazil demonstrates strong similarities to the world‐class iron ore deposits of the Carajás; field exploration is now underway.
2D profile modelling of regional aeromagnetic data by Southern Geoscience demonstrates that the Canga Iron Ore Prospect has comparable magnetic susceptibilities and geometries to the magnetic responses modelled over Vale’s giant Serra Sul (“S11D”) iron ore deposit, located 90 km away.
The Canga Prospect is represented by a regional magnetic anomaly that runs east‐west for a continuous strike length of some 7 km and discontinuously for up to 10 km. Within the anomaly, a high‐grade iron canga outcrop has been mapped over a strike length of >900 m and width of up to 150 m with surface rock chip assays grading 62‐69% Fe with low impurities.

About the Talk
Exploration for Ni-Cu sulphide deposits has been possibly the most significant factor in the development of modern minerals geophysical technology. The strong response of Ni-Cu sulphides to multiple geophysical methods has resulted in a heavy reliance on geophysics for exploration. This has, in turn, spurred researchers, instrument manufacturers and contractors to continually develop new and/or improved technology.
As discovery of outcropping and near-surface deposits is becoming rarer, the challenge is moving into covered areas and exploring deeper. Historical technology has proven effective in the 0-250m depth range; current technology has extended this to more than 500m; new developments are pushing this towards 1000m. This means that large prospective areas previously considered fully explored in the past have completely new potential.
This talk discusses:
- The current state of the art in geophysical acquisition, power, resolution, sensitivity, inversion, visualisation, and modelling.
- The physical properties of Ni-Cu sulphides, host rocks, and complicating non-economic geological features.
- The key geophysical methods, their application, and global examples.
- Regional targeting to identify settings containing prospective mafic-ultramafic rocks including the concepts of lithospheric structural control and intracrustal magma chambers.
