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.

New SRC Sport talks about campus pride
2014-10-21

Media Studies and Journalism student, Dominique de Gouveia, can attest to the fact that you need to take all the small steps before you make the giant leap.

As Residence Committee member for Sport since her first year, Dominique found the transition to the Student Representative Council (SRC) merely a case of now putting on the striped blazer. Having worked closely with Lourika Hugo, previous SRC Sport, there was not really much that she had to take grasp of.

“Our varsity has almost the same sport fixtures every year, so once you understand it, it should not be that difficult to follow through,” says Dominique confidently.

“You need to set goals in order to achieve them. I quickly realised that this is what I want to do. Sport is very big on our campus among the students and in my term I want other channels to realise the importance of sport.”

“The motto of previous SRC Sport, Tshepo Moli, was ‘transformation in sport’, which can indeed make a social impact on our varsity.”

“Through sport, our varsity can take pride in showing diversity.”

The variety of sports Dominique enjoys playing and watching, shows just how much she really loves what she is doing.

“My favourite sports have to be soccer and squash. But after watching the Varsity Netball this season, it made me wish that I had learnt how to play netball as far back as high school.”
