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.

Kovsies heading to Varsity Netball finals – again!
2014-10-14



The Kovsie Netball side is well underway to hold onto their champion status in the Varsity Netball Championships. On Monday evening, 13 October 2014, they beat NWU-Pukke 51–45 in the semi-final that took place on our Bloemfontein Campus.

The ladies from the UFS established a comfortable lead early on. Despite a strong comeback effort from NWU, Kovsies ended the game as conquerors with their second consecutive final ahead of them for next Monday.

Our team could hardly ask for better supporters, as the crowd roared them on to a winning score. They made the most of every attacking opportunity on court and played an offensive match. This was especially evident during the power plays – a period of time during which each goal is worth two points.

NWU-Pukke managed to fight their way back, coming within a goal of their hosts. But Kovsies went into a well-earned 10–6 lead during the first break. Kovsies’ Danelle Willemse and Ane Botha impressed with their accuracy at the hoop and clinically-executed shots at goal. At half-time, Kovsies had built up to a 27–14 lead.

The home side was in complete control of the game as they went into the final break with the scoreboard at 43–31. NWU’s effort fell short in the last quarter, though, and they could not snatch the victory from the defending Kovsie champions.

Kovsies will face the Tuks team in Pretoria on Monday 20 October at 18:45 for the final of the 2014 Varsity Netball tournament.
