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.

Southern Geoscience Consultants are excited to be working with Constellation Resources Ltd (ASX: CR1) on the detailed high-resolution airborne magnetic survey and semi-regional gravity survey datasets within tenement E28/2403 (70% Constellation, 30% Enterprise Metals Limited (ASX: ENT) which is located between the recent Mawson NiCuS discovery – Legend Mining Limited (ASX:LEG) and the Lantern Prospect – Galileo Mining Limited (ASX:GAL) with the Fraser Range.  The processing and interpretation of the resultant data has led to the delineation of ten high priority targets across this tenement, and the Company intends to commence an air-core drilling program in the next quarter.

SGC Consultant Geophysicist Russell Mortimer is managing the geophysical efforts which will now involve inversion modelling of the magnetic/gravity data to both assist prioritisation of the targets identified and aid positioning of the air-core drilling.  The key aim of the drilling program is to confirm the presence of mafic intrusions with favourable litho-geochemical characteristics.

Southern Geoscience Consultants would like to congratulate Mincor Resources NL (ASX: MCR) on their ongoing diamond drilling at the Cassini nickel sulphide deposit at Widgiemooltha has returned another exceptional high-grade nickel intercept which yielded 17.6m at 5.0% Ni (including 13.0m @ 6.1% Ni – MDD339), interpreted to be within the CS4 channel. The first hole of the program, MDD338 was designed to test the CS4 channel up-dip in a shallower position to allow for any potential changes to the basalt model and provide a DHTEM platform, which has ultimately provided the vector/target for MDD339. SGC Consultant Geophysicist Russell Mortimeris managing the ongoing geophysical efforts at Cassini which involves the use of high powered, very low frequency DHTEM surveying logging utilising multiple transmitter loops to both define complex conductor geometries and strengthen/constrain the overall interpretation.

Southern Geoscience Consultants congratulate Centaurus Metals (ASX Code: CTM) on intersecting broad zones of semi-massive to massive nickel sulphides in their first three drill-holes completed as a part of its maiden drilling campaign at the Jaguar Nickel Sulphide Project in north-eastern Brazil.

Centaurus report sulphide zones encountered correlate extremely well with historical high-grade intersections, and with the Down-hole Electromagnetic (DHEM) and Fixed-loop Electromagnetic (FLEM) conductor plates, which were recently modelled by SGC Principal Geophysicist Grant Couston as part of re-processing work on historic data.

Centaurus agree that the electromagnetic technique is the appropriate geophysical methodology for delineating targets in all future in-fill and extensional drilling of the high-grade nickel sulphide targets at Jaguar.

Dreadnought Resources (DRE) have completed their second drillhole, CHDD002, into the second FLEM target at their Chianti VMS prospect at the Tarraji-Yampi project in W.A.’s far north. The hole intersected two zones of stringer and semi-massive to massive sulfide mineralisation in what is interpreted to be an overturned and folded VMS system.

The results of the drilling have confirmed the geophysical models produced by SGC Principal Geophysicist Grant Couston, from FLEM data acquired by SGC’s own acquisition crew during a helicopter supported field campaign earlier this year. A DHEM crew is now being mobilised to follow-up on these exciting results. SGC would like to congratulate the DRE exploration team and Managing Director Dean Tuck on the systematic and integrated approach to targeting which has led to their success at Chianti.

Current News
Sub Audio Magnetics (SAM) is a patented technique that allows for the simultaneous high definition mapping of the magnetic and electrical properties in the ground – without sacrificing either quality or efficiency. Standard surveys can require grounded electrodes, levelled sensors and stationary measurements – limiting the terrain that can be covered in a day.
Spatial resolution is therefore often sacrificed for survey area coverage rates. The SAM technique bypasses such issues – providing particularly good value for money survey.

SGC are specialists in geophysical exploration for many commodities and mineralisation styles with a key focus on gold discovery. Potential field methods (magnetics and gravity) are used to map magnetic minerals and density variation to produce litho-structural geological maps, 3D models and to identify targets.
Electromagnetic methods can identify, map and model conductive gold-related massive sulphides including those related to BIF deposits and shear zone controlled conductive sediments. Sub-audio magnetics simultaneously maps magnetic and electrical characteristics of rocks including mineralisation and/ or related geological features such as shear zones, disseminated and massive sulfides. Induced polarisation can directly detect disseminated and massive sulfides, and map lithology and alteration.
