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.

Professor lectures class – from his closet!

A professor, and lecturer, at the University of the Free State (UFS) nowadays gives ‘class’ in his sleep and from within his walk-in closet.

Prof Vernon Louw from the Department of Internal Medicine at the Faculty of Health Sciences recently began to make video recordings in which he presents his lessons in his discipline of Internal Medicine and Haematology.

In the mean time, due to the lack of a studio, he does his recordings in his walk-in closet where it is soundproof.

“I started the videos as a personal initiative, since there is great potential to create a completely integrated platform from where the students can watch the videos in their own time. It also provides us with more time to work interactively with our students in the class, since they already watched the videos on their own or can perhaps watch it later.”

The videos, which are viewable on Youtube under the name ‘Vernon Louw – MedEd’, are very specific and concepts are explained step by step with the objective of mastering them in ten-minute videos. There are already five videos uploaded and students from over the world can view them.

“The benefit is that now I can ‘lecture’ while I sleep. It is wonderful to notice in the mornings that another 20 viewers somewhere in the world joined.”

Prof Louw says that most of the videos are currently watched by mainly South-African, American, Indian and British viewers.

The videos can be watched on the Youtube channel: Vernon Louw MedEd
