Project: Electromagnetic (EM) Gradiometry as a Perfect Tool for EM Tomography – a Novel Approach (with applications to EM Mammography)

EM gradiometers have been considered as a valuable tool for Magnetic Induction Tomography (MIT). It has been proved that healthy human tissue has different electrical conductivity compared to abnormal tissue such as malignant tissue of breast. A short base-line EM gradiometer, if sensitive enough, can act as a non-invasive scanner and produce 3D images of abnormal conductivity contrasts in human body. Currently, this is an active area of research in medical physics.

An Extremely Low Frequency Interferometric System (ELFISTM), which has been developed at the Trinity Research Labs, uses a unique interferometric signal processing capable of operating in the Extremely Low Frequency (ELF) range with unprecedented sensitivity. The system has been initially aimed at geophysical prospecting and was successfully tested at Australian Outback over potential nickel deposits. It has also been supplied to the Institute of Electronics of the Chinese Academy of Sciences in order to be compared with similar techniques, and was successfully tested in the field. By its very nature, interferometric signal processing is a gradiometric type of the measurements as it discriminates between two signals. This makes it possible to use this principle in EM gradiometers. EM Mammography, which does not require any direct contact with patients, is the most promising and an immediate application of the ultra-sensitive EM Gradiometer.



A new scaled down version of the ELFISTM – based laboratory prototype has been built and tested in the laboratory as a short baseline EM Gradiometer. It is capable of measuring extremely small spatial variations in the amplitude and phase gradients of the secondary EM filed produced by conductivity contrasts in a surrounding host environment at short distances from the latter. They both contain valuable information about depth and boundaries of such abnormal conductivity spots.

Project: A Novel Interferometric Geophysical Surveying System for the Search of Massive Nickel Sulphide Deposits


An improved field-deployable version of EM ELF Gradiometer, mounted on a mobile platform, was used on the MCG tenements within the Fraser Ranges area in Western Australia.



A number of conductive anomalies had been detected at either known locations or along previously unexplored lines. The raw data had been processed, analysed and reported to the MCG office in Perth CBD. The fine details of these surveys are under active confidentiality agreement with the MCG.


The Institute of Electronics (IECAS)

Nov 2013 – May 2014

The Chinese Academy of Sciences (Beijing, China)

Project: An Extremely Low Frequency Interferometric Geophysical Surveying System – Laboratory and Field Testing

A complete set of ELFISTM hardware and software has been supplied to the IECAS under a collaboration agreement signed between the Trinity Research Labs and the IECAS.The apparatus did firstly undergo extensive laboratory testing and a comparison between the ELFISTM technology and most close developed analogies was conducted. The whole system then was transported to Inner Mongolia province in order to undertake field-testing over existing conductive mineral deposits.



The Trinity Research Labs and the IECAS have agreed to establish a long-term collaboration in the area of geophysical exploration by means of the ELFISTM technology. The technology requires further investment in terms of money and manpower and both parties are willing to contribute to further development.

Low noise specialized analog electronic blocks have been designed and manufactured for the Ultra-stable Clock Oscillator System that has been developed by the Metrology Division team.


The electronic blocks, that have been manufactured at the Trinity Research Labs, are now integral parts of the most accurate time reference system – the Ultra-Stable Clock Oscillator, with a commercial value of ~ $ 0.5 mln. The Trinity Research Labs is the only supplier of this fine electronics under close collaboration with the UWA Metrology group.


Regis Resources Pty Ltd (Western Australia)

Project: An Extremely Low Frequency Interferometric

Geophysical Surveying System – Field Testing and Measurements Over Potential Nickel Deposit

An early version of the ELF EM gradiometric surveying system was tested in the field, a 1000 km north to Perth (WA) on the Regis’s mining tenements. The Regis’s package of tenements in Western Australia lie directly to the south of tenements controlled by BHP Billiton and Falcon Minerals, which hold the Olimpia Nickel, Copper, PGE massive sulphide mineralisation. Previously, the area was surveyed with moving loop TEM (MLEM) using single turn 200m x 200m loops and base frequency 2.08 Hz. The survey was conducted over Hermans prospect which lies directly along strike approximately 15km to the south of the Olimpia mineralisation. Analysis of the data showed a highly elevated conductivity of the overburden at Hermans, with a distinct lack of obvious deeper conductive features, despite geochemical signatures indicating the likely potential of mineralised sulphide material.



Initially the EM gradiometer survey was completed across several known EM conductors, located at Tasman and Mocha. On most survey lines the data was collected using 2 methods: readings were taken while the vehicle was run at a constant speed ~4km/hr, and 10 sec readings were collected at 5 metres station spacing. Both methods worked well, resulting in quality data, if the grid line was graded. The system detected several anomalies at Tasman. Their exact locations were reasonably well determined when the data had been processed. The EM conductor at Mocha was easily identified.

The EM gradiometer was then trialled at the North WUZ area, including the Giles Nickel Prospect, where there is highly conductive overburden. The first line at North WUZ tested carbonaceous shale at known location. The system was then run across several lines at the Giles Nickel Prospect. The outcome of the field trial has been positive, the system was able to identify known EM conductors at Tasman and Mocha and a number of anomalies were detected in the data collected at the North WUZ.
