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.

Spring graduation an event second to none

This year’s Spring Graduation on the Bloemfontein Campus of the University of the Free State was a truly unique event.

From the moment Shenley Pretorius, a blind singer, opened her mouth to sing, a sensational ceremony unfolded in front of the 650 graduandi, their family and friends. The political analyst, puppet Chester Missing, was ‘released’ from his suitcase and – true to form – unleashed a pandora’s box of hilarity into the crowd. From beginning to end, the programme provided an occasion to be remembered for years to come.

Fifteen-year-old Shenley Pretorius, a Grade 9 learner at the Prinshof School for the Visually Impaired in Pretoria, performed her self-composed song, ‘I see you with my soul,’ sending shivers into the audience, followed by a version of Lady Antebellum’s ‘Never Alone’.

After her performance, a bustling Conrad Koch prepared the audience for his puppet, Chester Missing’s stream of whimsical satire. The on-stage antics of this cheeky ‘political commentator’ had the crowd crying with laughter with the now-famous twerk and did not disappoint with his ample mockery of politicians and celebrities. From President Jacob Zuma, Helen Zille, Julius Malema, Zwelinzima Vavi, Larry King to the cellphone manufacturer, Blackberry – nobody was spared.

In his speech, Prof Jansen highlighted the achievements of current and former Kovsie students. Sharing the stage with Prof Jansen was just such an example – former UFS student Johan Cronje. Recently, Cronje palmed in a bronze medal in the 1 500 m at the World Championships in Moscow.

"Don’t worry about where you came from. Worry about where you are headed to. Don’t let anyone tell you what you can or couldn’t do." With these words, Prof Jansen sent the new Kovsie graduates into the world.
