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.

The University of the Free State received its third A-rating from the National Research Foundation (NRF) when Prof Jonathan Jansen was awarded an A2-rating.

Prof Jansen is a Senior Research Professor in Education secondary research field and field of specialisation: Development education and Curriculum theory at the UFS Faculty of Education and Fellow at the Center for Advanced Studies at Stanford University in the US.

Prof Jansen’s rating follows P-rating
Prof Jansen’s rating also adds to the recent P-rating awarded to Dr Daniel Spence, a postdoctoral Research Fellow at the International Studies Group. In receiving the rating, the UFS became the only university in South Africa with a P-rated researcher in History.

P-ratings are given to young researchers, usually under the age of 35, who have the potential to become leaders in their field. Researchers in this group are recognised by all, or the overwhelming majority of, reviewers, as having demonstrated the potential to become future international leaders. 

“Obtaining another A-rating is indicative of the university’s drive to enhance its research profile – nationally as well as internationally. I am thankful to our scholars for their commitment to the rating process and look forward to receive the results of this year’s ratings,” said Prof Corli Witthuhn, Vice-Rector: Research at the UFS.   

Total number of researchers increased
The UFS has also upped the ante with regards to its total number of NRF-rated researchers during the latest rating and evaluation with an increase from 127 in 2015 to 149 rated researchers in 2016.

In 2015, Prof Maxim Finkelstein from the Department of Mathematical Statistics and Actuarial Science, and Prof Melanie Walker, Senior Research Professor and Director of the Centre for Research on Higher Education and Development, were given A-ratings.

Prof Finkelstein’s rating then made him the only A-rated researcher in ‘Probability and Statistics’ regarding Mathematical Sciences in the country. Prof Walker was evaluated and graded in the division for Research, Innovation Support and Advancement.

According to the NRF, A-rated researchers are “unequivocally recognised by their peers as leading international scholars in their field for the high quality and impact of their recent research outputs”.

 

The rating of individuals is based primarily on the quality and impact of their research over the past eight years.
