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.

Vishuis’s fourth Varsity Cup victory about more than rugby

For Vishuis, it is about more than just rugby.

This is what Henco Posthumus, captain of House Abraham Fischer’s rugby team, had to say after his team was crowned the national Varsity Cup champions for an incredible fourth time. According to the flyhalf, the title of the leading residence team in the country is “special for the guys”.

Vishuis is the most successful residence team in the history of the tournament. Apart from their four titles, they have played in a total of five Varsity Cup finals.

On 11 April 2016, the residence from the University of the Free State (UFS) launched a great comeback in Stellenbosch to beat Patria (Pukke) by 37-29. This victory ensured that Vishuis was unbeaten in 2016.

Great fighting spirit


The Kovsies started off well against Patria, but were behind 16-29 shortly after break, and had to “delve deep”, according to Posthumus. “To be behind in this way is not what one would prefer. For some reason, we have been in similar situations before, and we know how to make a comeback,” he said.

“We looked one another in the eye and decided that we are not going to lose again in the final.” In last year’s final in Bloemfontein, when Posthumus played at fullback, Vishuis got stuck against Mopanie (Tuks) at the end of the match, and they wanted to prevent this from happening again.

Heymans a hero


According to the Vishuis captain, one of his team’s assistant coaches, Franco (Vaatjie) van der Merwe, spoke harshly to the players when they were behind. The victory was clinched in the dying moments, with the second try of scrumhalf, Ruben Heymans, when the score was 29 points each. Heymans was a star, and the well-deserved Man of the Match.

Posthumus said it is a great privilege to carry the title of Varsity Cup champions. His team has worked hard to reach the top.
