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.

Nine Kovsie students awarded NAC bursaries
2015-02-19

The UFS is proud to announce that nine of our Drama and Theatre Arts undergraduate students have been awarded National Arts Council (NAC) bursaries for their studies in 2015.

From the left in the photograph, these students are:

• Mbuyiselo Nqodi (first year)
• Marike Jonker (second year)
• Monique de Klerk (second year)
• Aldine van der Merwe (third year)
• Kado Cloete (third year)
• Rondo Mpiti (third year)
• Magnus McPhail (third year)
• Olivia Wyngaard (third year)
• Marica Laing (second year)

This year the amount awarded for the NAC busaries is R70 000.

Since 2005, the NAC has given bursaries to the UFS for the last 10 years. The amount varies from year to year.

“The number of undergraduate students who benefit varies depending on the amount allocated each year,” said Prof Nico Luwes, Head of the Drama and Theatre Arts Department at the UFS.

“Some years, the NAC prescribes how many students will be awarded a bursary and provides a profile of gender and academic prerequisites. Other years, such as the present one, there is no prescription and the UFS was able to cater for the applications submitted, and the number of students who will benefit, within the amount awarded. Normally, it is divided between successful candidates.”

The criteria according to which NAC bursaries are awarded to students every year include academic merit and, of course, their financial situation.”

“The full information of applicants from the Department of Drama and Theatre Arts is checked by the selection committee – all permanent members of staff in the department. The names are then sent to the NAC for approval.
UFS Finances ensures further that the bursary money is paid into the student’s class fees account. During the year and at the end, I report to the NAC on the progress shown by bursary holders. This, in turn, contributes to the excellent co-operation with the NAC so that the following year’s application is then generally successful,” says Luwes.

Bursary monies cover mainly registration and class fees for some or all modules, depending on the amount awarded.
