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.

Our university honoured our top athletic achievers at the annual Kovsie Sports Star Awards that took place on 23 October 2014.

Maryka Holtzhausen and Wayde van Niekerk were named Sportswoman and Sportsman of the Year respectively.

Holtzhausen captained the Protea netball team that participated in a host of test series and championships. These included:
•    a test series against Trinidad & Tobago and England in October last year,
•    the Fast Five World Series in Auckland, New Zealand during November 2013, as well as
•    the Commonwealth Games in Glasgow this year.

Van Niekerk, in turn, set a new SA record in the 400 m of 44.38 at the Diamond League meeting in New York, USA during June 2014. As a member of the Protea team who participated in the Commonwealth Games in Glasgow earlier this year, he won the silver medal in the 400 m sprint. In August 2014, Van Niekerk clinched the silver medal in the 400 m at the CAA Senior African Athletics Championship in Morocco. He also formed part of the CAA African Athletics team who competed in the intercontinental cup meeting during September 2014. The team won gold in the 4x400 m relay at this event.

The Junior Sportsperson for 2014 is Driaan Bruwer. He was a member of the SA U/19 cricket team that won the Junior World Cup this year.

Our university’s sports stars were honoured in the following five categories:

•    Sportsman and Sportswoman of the Year. Everyone that represented South Africa at a senior level was eligible for the title. The winners each received a trophy and each sportsman and sportswomen in this category were honoured with a medal.
•    Junior Sportsperson of the Year. The winner received a trophy.
•    Sports stars that represented South Africa at senior and junior level. The achievers received certificates.
•    Sports stars that represented the UFS in the national student teams. These sports stars also received certificates.
•    Certificates were also awarded to the KovsieSport Club sports stars.
