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.

“How do you like my new blazer? Do you think these stripes suit me?” These were the words of the newly appointed Vice-Chancellor and Rector of the University of the Free State, Prof Francis Petersen, as he took to the stage in his #ProudlyKovsies blazer to welcome the 2017 first-years to the Kovsie family.

The event, which was also the start of the first-year Gateway Programme, took place on Saturday, 21 January 2017, and saw first-years and their parents make their way to the Red Square on the Bloemfontein Campus where they were formally welcomed.

UFS to produce world graduates
As newcomers, Prof Petersen wanted the fresh faces to feel welcome, to feel a sense of belonging. “You are now a Kovsie, and we want you to experience that Kovsie life until you graduate,” he told them.

During his speech, Prof Petersen reassured parents that the academic year would be completed and that the UFS would operate as an institution. He encouraged the students to absorb and gain knowledge and said the university would strive to ensure excellent knowledge. “At the UFS, we want to produce graduates for the world, and we need to ensure that we use our knowledge to uplift society,” he said.

Use differences to benefit from one another
KovsieFM presenters, Tshwaro Thothela and Gontse Choane played host to the gathering and Pura Mgolombane, Dean of Student Affairs, encouraged the first-years to use their differences to benefit from one another and to learn from this opportunity. “Make sure that the good that you do is for yourself, for others and for the university,” he said.

Prof Nicky Morgan, Acting Vice-Chancellor and Rector, welcomed Prof Petersen, his wife Cheslyn, and their two sons, Curtis and Clayton, to the UFS.

The newcomers also had an opportunity to visit their respective faculties and get to know the staff and facilities better.
