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.

Kovsie student on his way to the record books
2011-10-12

Ten hours. That’s how long Kovsie student Hermann van Heerden held a stationary wheelie in his wheelchair by lifting the front wheels of his wheelchair. The second-year disabled student now stands to get his name in the Guinness World Record Book for the longest stationary wheelie in a wheelchair.

Starting at 03:15 and holding on until 13:15 on Tuesday, 11 October 2011, Hermann achieved what he set out to do. Now he is waiting for the Guinness World Record office to verify his world-record attempt.

The minimum time set for Hermann to achieve a Guinness World Record was four hours, but the B.Ed. student went six hours over this time, wheeling non-stop for ten hours. During this time the Kovsie student had no food or water over his lips, nor was he allowed to go to the bathroom.

Hermann’s Guinness World Record attempt forms part of the ten-year celebrations of the Unit for Students with Disabilities (USD) at the University of the Free State (UFS).

Accomplishing his record attempt, a tired Hermann said the first thing he wanted to do was to eat. Hermann, who was born with spina bifida, a developmental congenital disorder, said he did not have a lot of preparation for his world-record attempt, as he had always been in a wheelchair.

According to the Guinness World Records press office, the closest record to the one Hermann set out to achieve, is for the longest continuous wheelie in a wheelchair. This was achieved by Michael Miller from the USA who covered a distance of 16, 12 km on the rear wheels of his wheelchair.
