“In my former capacity as the manager of the Geoscience Department at Anglo Technical Services, I made use of the services of ASST on a number of occasions to provide electrical and borehole radar geophysical surveys in mine and on mine site. ASST were outstanding in their technical capability, professionalism, and uncompromising commitment to the company safety standards. I can highly recommend ASST as a competent geophysical service provider that will deliver data and results of the highest quality.”

“Galt Geotechnics has worked closely with ASST Pty Ltd since 2009. We have always found ASST to be highly professional, knowledgeable and proactive. Riaan Mouton is always willing to share his extensive knowledge and keen to try new/different techniques. ASST’s costs are always competitive and they have always delivered within the agreed project schedule. We have no hesitation in recommending ASST for projects of any size and ground conditions.”

“In my role as Exploration Geologist for Mustang Resources, I had the pleasure of working with Riaan, Director and Geophysicist of ASST and we have been very pleased with the high quality of work and rapid turnaround time.  Riaan and his team have completed numerous surveys – which have resulted in many successes for the company.  Riaan also acts as Mustang’s Competent Person for geophysics.

Mustang first contracted ASST to have complete ground surveys over several of our graphite prospecting licenses.  The EM surveys produced positive anomalies subsequent drilling intersected graphite mineralization.  The ground EM work was highly successful and worked very well as a targeting tool for the initial exploration of graphite mineralization as recommended by ASST. In terms of production rates in the field, ASST performed well above industry standards. ASST provided Mustang with daily feedback and recommended drill targets immediately which allowed Mustang’s ground team to organize a drill team and get confirmation of graphite mineralization within a few days of the survey being complete.

This highly successful ground EM project recommended by ASST was a cost-effective method of validating the presence of graphite in the early stages of Mustang’s exploration project. 

ASST was appointed as independent consultants to plan, manage, model, and interpret an airborne EM campaign that followed.  ASST placed a tender process to evaluate the advantages and limitations of the different airborne contractors.  Riaan summarised the information received from vendors and provided Mustang with his recommendation based on his experience and the information provided in the quotes.  ASST performed modeling of the EM data with priority drill targets.  Subsequent drilling resulted in excellent results.

We would highly recommend ASST for projects of any size and ground conditions.”

“ASST performed some geophysical surveys for the company I work for, Fortescue Metals Group, at Cloudbreak Mine site, Western Australia. They were professional and prompt, complied with all safety requirements and produced good results. Happy to recommend them.”

“ASST was very responsive and helpful in defining the investigation scope of work and diligent in conducting the fieldwork. Riaan and his crew were great people to work with. I would have no hesitation in getting them involved in our future site investigation projects.”

“Having worked as a manager in the junior explorer sector of the mining industry for over 30 years, with companies including Adelaide Resources Limited, Phoenix Copper Limited, Perilya Limited, and Barminco Ltd, I had often found myself a geologist attempting to undertake Geophysical programs including Induced Polarisation, Magnetic and Radiometric surveys. After being introduced to Riaan Mouton from the Applied Scientific Services and Technology Group I quickly learned that it was far more efficient and cost-effective to employ a Geophysicist to do the geophysical surveys. I have worked with Riaan for over ten years and no job is too big or too small for Riaan, his superior computing and technological skills meant that he doesn’t need to spend excess time on the ground, he comes fully prepared and our jobs were done so much faster and cost so much less than those we had attempted previously.”
