Dr Martin Clark
Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

Mining has historically been described as a boom-and-bust industry, where fluctuations in mineral prices could result in extreme success or bankruptcy. Successful mining companies closely monitor assets/expenditures, risks, and other parameters associated with their business to best ensure their longevity. In most mineral industries, there are a few competitors that dominate the delivery of a mineral resource. As a result, technological development, along with other factors, are critical to ensure that these companies’ business remains viable and protected.

This is according to post-doctoral fellow in the Department of Geology, Dr Martin Clark.

Drone technology: better, faster, safer

He says technological development in mining generally translates to how a company can extract a resource from the ground better, faster, and safer. 

Dr Clark believes the rapid development of drone technology represents a shift in the toolbox that mining companies can employ.

“Drones can collect a great deal of data randomly over vast or small areas within hours, historically accomplished by mapping campaigns which can last months to years. Drones can also collect data in areas which are difficult and dangerous for humans to get to. These include cliff faces or rock walls that are difficult and dangerous to get close to, as well as stretches of land where dense vegetation, inaccessible terrain, and even atmospheric dangers become factors which reduce or modify the scope of exploration work,” he said. 

Expanding application of drones

Dr Clark’s work specifically focuses on expanding the applications for which drones are used. “I assess what and how good the imaging capabilities of drones are, use the imagery to generate 3-D models to drive scientific observation, and yield results which can help companies to extract resources. This initiative is called MAGIC (Multi-purpose Aerial Geological Image Classification),” he said. 



“MAGIC aims to collect geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes,” he added.

Dr Clark is not only the founder of MAGIC; he also drives multiple aspects of the initiative including education, research, and business development. 

In 2013, when he was busy with his doctorate, there was already a spark of interest in using drones to address geological questions. At that time, Dr Clark was working with remotely sensed high-resolution LiDAR imagery to better understand geological structures at the Sudbury Mining Camp in Canada. The interest became a reality in 2018, when he applied this initiative during his post-doctoral fellowship at the UFS.

Now and the future

“At present, there are no direct mining projects underway, but projects are expected to begin in 2020. Drone operation and image-analysis techniques are currently being refined for industry,” he said. 

Besides his work with drones, Dr Clark also work in the fields of structural geology, remote sensing, and geospatial data analysis.

Prof Finkelstein current and only A-rated researcher in Probability and Statistics in SA

Prof Maxim Finkelstein from the Department of Mathematical Statistics at the University of the Free State (UFS) received an A-rating from the National Research Foundation (NRF). This makes him the only A-rated researcher in ‘Probability and Statistics’ regarding Mathematical Sciences in the country.

According to the NRF-rating process, a person with an A-rating is a world leader in his field. 

Prof Jonathan Jansen, Vice-Chancellor and Rector, said: "I am absolutely delighted for Professor Finkelstein and for the fact that this is one of the clearest signs that the UFS has significantly increased its standards of research across the institution as a whole."

Prof Finkelstein says this rating means a great deal to him, since it is a reflection of his dedication and perseverance.

“Of course, the rating is not a goal in itself,” Prof Finkelstein says. “The goal is the high quality research and the rating is just an objective indication of this. Along with the satisfaction, this rating brings the responsibility for maintaining this high status in the future.”

Prof Finkelstein conducts his general research in the field of ‘Probability and Statistics’, but his specific area of focus is ‘Stochastic Modelling’. Prof Finkelstein solely lectures postgraduate students and also mentors a few master’s and PhD students. This affords him the time to mainly concentrate on his research.

“Finally, I wish to emphasise the fact that high-quality research became the prime goal at the UFS,” says Prof Finkelstein. He underscores the efforts of the Vice-Chancellor and the Vice-Rector: Research in creating excellent possibilities for researchers. This has already resulted in remarkable improvements in the UFS’s research outputs – and consequently an increase in the number of rated researchers at the university.

A total of 119 UFS researchers currently have evaluation and rating status from the NRF, says Nico Benson, Deputy Director: Research Development. Currently (October 2014) 29 researchers are still waiting for response from the NRF regarding applications submitted. A total of 16 ratings are already known. On the Qwaqwa Campus of the UFS, five researchers are rated.

Prof Finkelstein's A-rating will become effective from 1 January 2015. Ratings are valid for a period of six years and researchers are invited to apply for re-evaluation in the fifth year.
