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.

UFS becomes Varsity Netball champions – again
2014-10-21

Kovsies has become the first team to successfully defend the Varstiy Netball title when they beat Tuks 49-42 in the 2014 final in Pretoria on Monday 20 October.

University of Pretoria (Tuks) might have been unbeaten for the entire 2014 tournament, but this did not hinder Kovsies in becoming the Varsity Netball champions for a second consecutive time.

From the outset, both these furiously focused teams fought hard and only after ample turnovers could Kovsies finally manage to open the score board.

The Mostert sisters, Karla and Tanya, won a couple of crucial balls, leaving the UFS dominating possession in the opening exchanges.

When Tuks eventually got to scoring, they could not stop the UFS from rushing to a 9-3 lead after the first ten minutes. The visitors had established a 13-5 advantage by the first break, keeping the Pretoria crowd quiet.

The home side came back shooting in the second quarter with great determination, fighting their way back into the game. Tuks ran hard, needing to work hard against Kovsies, who still managed to be in the lead with 22-16 at half-time.

Kovsies made good use of their power play early in the third quarter to stretch their lead further to 30-22. They made the most of their opportunities, going into the final quarter with a 39-31 upper hand.

Even though Tuks made a couple of changes during the final break, they could not avoid defeat in the end.

Kovsies’ Lauren-Lee Christians was also the player of the match, while the champion’s captain, Karla Mostert, was announced as the Player of the Tournament.

This hard-working defender made a number of crucial interventions alongside her sister Tanya in the final. Karla proved that she was the fans’ tournament favorite, claiming the most votes and winning a Samsung S4.
