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.

Louzanne Coetzee breaks 16-year-old world record

Whether it’s the 5 000 m or the 1 500 m, Louzanne Coetzee is breaking records in all her races. Fans of the University of the Free State (UFS) student were elated at her triumph with the 5 000 m T11 world record at the Nedbank National Championships for the Physically Disabled on Wednesday 23 March 2016.

The record, which has stood for 16 years, was shattered by Coetzee’s stellar 19:17.06 performance. Sigita Markeviciene’s long-standing mark of 20:05.81, set at the 2000 Paralympics in Sydney, was bettered by 48.75 seconds when Coetzee and her guide, Khotatso Mokone, sprinted hand in hand past the finish line. 

Coetzee’s coach is as elated as the world-class athlete’s fans over her officially becoming the first totally blind female to clock sub-20 minute in the 5 000 m. "I am proud and grateful. She earned it through and through. She worked hard for this,” said Rufus Botha.

The experience was a surreal one for Coetzee. “It was unreal but it is exciting to be the fastest in Africa and the world. I could not have done it without the support system that I have,” she said.

"I have seldom met a student with the character and humanity of Louzanne Coetzee; she represents the best of campus and country, and is a stunning example of what we canal  achieve despite the great challenges of the present," said Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

New African record holder

Two days before breaking the 5 000 m world record, Coetzee set a new African record in the 1 500 m. She lowered the mark from 5:27:21 to 5:18:44, which placed her at the number nine spot in the world.

On Friday 18 March 2016 Coetzee had broken her own South African record when she ran 5 000 m in less than 20 minutes at the Free State Championships. However, the race is not an official (International Paralympic Committee) meeting, and hence remains unofficial.

What’s next?


The gold medallist is currently preparing for the Athletics Grand Prix to be held in Switzerland in May for which she is raising funds. If she is selected by SASCOC (South African Sports Confederation and Olympic Committee), her next stop is the Paralympic Games in Rio de Janeiro, which is just six months away.
