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.

UFS academic leaves for national parliament
2009-05-28

The Head of the Department of Afro-asiatic Studies, Sign Language and Language Practice at the University of the Free State (UFS), Prof Annelie Lotriet (pictured), is leaving the university at the end of this month.

Prof Lotriet has been seconded to the national parliament as a member of the Democratic Alliance’s shadow cabinet responsible for arts and culture.

“I am very sad to go because I think I am leaving the university at a point where there are many changes coming and I think we are going to go into a very interesting and challenging time at this university with our new rector taking office one of these days,” she said.

“On that point I am actually sad that I am not going to be here to experience it because I think the university has all the potential to become one of the main role players in higher education in South Africa and, obviously, I will be watching it with interest.”

Prof Lotriet has worked for the UFS for 25 years and regards language and multilingualism as her passion. She reflected on her major achievement: “I think what still stands out for me was the fact that we ran the interpreting service for the Truth and Reconciliation Commission and that made an indelible impact on my life. We were involved in it right from the start to the end. We really put interpreting on the map.”

Mr Philemon Akach, a senior lecturer in the department, will act in her position until the end of the year.

“I have full confidence in him,” she said. “He is a world-renowned expert in interpreting and sign language, so I think the department is in good hands.”
