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.

Starting in 2016, the UFS Marketing department embarked on a project designed to help learners from less fortunate backgrounds to discover their potential. This competition, dubbed Kovsies Star of Stars, recognises excellence in some of the most disadvantaged schools in the Free State. C-Squared Group, a black-owned and -managed agency, is partnering with the UFS in this endeavour. Amongst many other prizes on offer, the winner is awarded a full bursary to study at the UFS.

For the first year, two of the five Free State districts were identified, namely Xhariep and Motheo. Grade 11 and Grade 12 learners were invited to participate in 2016, the winner being announced at a gala event on the Bloemfontein Campus early in 2017, with Success Lekabe as host for the evening.

Nomonde Mbadi, Director of UFS Marketing, says of the contestants, “All 11 Star of Stars finalists had one thing to say that gave the judges goose bumps, and that was: ‘We want to give back to our community.’ This is truly commendable.”

"Doctor" Tshepo Thajane, from Lefikeng Secondary School in Botshabelo, was selected as the winner of the inaugural Kovsies Star of Stars competition. He is pursuing a degree in Actuarial Sciences, and will be a Karee resident. He says, “I loved UFS before I even came here, because of the respect I was shown. And I really didn’t think I would win; it just came as a surprise to me.”

Lebohang Lesenyeho, from Kgauho Secondary School (Botshabelo), had a special word for the organisers. “I would be very honoured if you could include a message to them. We really thank them for this opportunity.”

It is hoped the competition will garner the support of financial sponsors and be expanded to include learners from Grade 9, 10, 11, and 12 across all five districts in the Free State province.
