Southern Geoscience Consultants (SGC) is a group of highly experienced geophysicists based in Perth, Western Australia, who provide independent, specialised consulting services to the mineral and petroleum exploration industries globally.

Working with all types of geoscientific data, our services include the planning, management, quality control, processing, imaging and interpretation of geophysical surveys, management of exploration programs, targeting and design of drill holes, GIS and data compilations, project evaluations, sales of multi-client data and value-added products, instrument rentals, rock property measurements and software development.

Since its inception in 1985, the group has consulted to over a thousand organisations worldwide and has been associated with several major discoveries, including the DeGrussa VMS deposit, Maggie Hays, Emily Ann and Cosmos nickel deposits, the Chatterbox gold deposit, and the Kintyre uranium deposit.


Hot Chili has been working with Southern Geoscience for almost four years now. We have always found SGC to be very helpful and knowledgeable and have been very pleased with the high quality service that they always provide.We have undertaken several aeromagnetic surveys in Chile which SGC have project managed for us, from the initial tender process through to delivery of final processed imagery. This is no easy task given language and time differences in Chile, but to SGC’s credit they have forged a good working relationship with geophysical service providers in Chile to make this happen.SGC have always been willing to complete any work that we require, and have been involved with our technical generative team discussions and planning. I would happily recommend SGC to any company looking for professional geoscience services.

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.

Highlights include:

  • 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

Venturex Resources announces new, high-priority targets have been identified on the immediate flanks of the Sulphur Springs deposit in the Pilbara, highlighting the potential for new VMS discoveries.

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.

The live talk will be held at the City West Function Centre, West Perth where the webcast will be recorded and uploaded to the ASEG website, so those unable to watch it live can watch at their leisure.

Date: Wednesday 18 October 2017
Time: 6:00 pm (WST = GMT+8)

via Zoom meeting software on Windows, Linux, Android and IOS. Registration details below.

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.
