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.

Fun and camaraderie key to Vishuis rugby success

They have not only been dominating the residence rugby scene at the University of the Free State over the past few years, but also nationally. Although they might experience added pressure as favourites, a key ingredient to Vishuis’ success story is their enjoyment of the game and their camaraderie.

According to Henco Posthumus, the Vishuis captain, they realise that it still remains residence rugby. “The guys pitch up at practice because they want to play, not because somebody begged them to.”

Comfortable triumph in final

Vishuis claimed their fifth Varsity Cup Koshuis title earlier this year, and will defend their national title after being crowned Kovsie residence champions on 8 September 2017. They beat Kagiso comfortably 38-16 in the K1 final, after leading by 31-9 at half-time.

Posthumus says the fun element is often forgotten, but not at Vishuis. He says it is not just about the first team either. “Almost every house member, no matter if he studies medicine or if he hasn’t played rugby before, is playing a bit of rugby on a Friday evening. That is also why we, as a fairly small residence, can field five teams.”

More than just a game

Although their proud record serves as motivation, it is about more than just rugby. “The guys grow together in different ways. It is an honour to see how they grow during a season, also spiritually.”

They have been lucky not to suffer many serious injuries over a number of seasons, Posthumus says. “We are privileged to have 110 years of history behind our residence, and people from within and outside buy into who we are.”

“Our (new) coach, Zane Botha, is also a valuable acquisition. He has taken our rugby to the next level.”
