Dr Martin Clark
Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

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.

Mosa Leteane introduces new era in student leadership
2014-10-02

The month of August belonged to South African women – in more ways than one. Not only did we celebrate Women’s Month, but our Student Representative Council (SRC) gained a female leader.

On 4 September 2014 Mosa Leteane became the first female SRC president at the UFS Bloemfontein Campus under the revised SRC constitution of 2011. Although her journey has been a hard and difficult one, it rewarded her with great insightful and invaluable experience.

Being elected to this seat is a milestone for female leadership as a whole at Kovsies. Having been the Prime of House NJ van der Merwe Residence, Marketing Officer of the premier Golden Key Society, Executive Committee member for the 2013/2014 SRC Legal and Constitutional Affairs – and being a legal student herself – Leteane brings a lot of experience to student governance.

Accountability is one of her core values– and that is exactly what she envisions to bring to the newly-elected SRC. Leteane also believes that having a moral sense is essential to the functioning of her SRC. Being a political science or legal student does not automatically imply high morals, Leteane adds. Rather, principles are fostered by the contribution that you want to make.

Something she is proud to have inherited from the previous SRC is the establishment of a blueprint for student governance and understanding team dynamics. These things define the success of any SRC.

With the amount of work lying ahead, Leteane says, she will draw strength from family and friends – and listen to some music.
