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.

South Campus supplementary schools foster future Kovsies
2016-07-13

The Monyetla Bursary Project, in partnership with the University of the Free State (UFS) and other sponsors, presents an annual Winter School for Grade 12s on the South Campus. In addition, a Saturday school for Grade 12s has been in operation since 2007.

 “Champion teachers
in the district
assist learners”

Chris Grobler, a science teacher at Navalsig High School in Bloemfontein, is the organiser of both schools. He says, “I saw it as a tragic state of affairs that those offering bursaries and the bright learners from our formerly disadvantaged schools were not meeting up with each other.”

The first year saw 300 learners attending, with five subjects being presented. This tally has since grown to 650 learners each Saturday, with 11 subjects being presented, including Business Studies, Computer Applications Technology (CAT), Geography, Maths, and English.

“Our vision was to get champion teachers in the district to assist learners to qualify for university bursaries,” says Grobler. The project has succeeded in attracting educators with extensive experience as chief markers or even subject advisors in the Department of Education.

Wider reach

“This year, the 1 200 learners at the Winter School hail not only from the Free State but also from as far as North-West, Gauteng, and the Eastern Cape.” Grobler says, “We are very pleased about this, as it means that the image of the UFS is being carried further afield.”

Lesego Modisele, one of the visiting learners from Parys, says, “I like how they brought in teachers that are heads of their subjects, who are very experienced and help us a lot. They explain how exam papers are set and which important things to focus on.”

By means of the Schools Partnership Programme (SPP), 250 learners from Thaba Nchu and Botshabelo have also been assisted. Katleho Setloho, who was one of these students, is currently a medical student at the UFS.

A special feature included in this year’s programme is interpreting services in South African Sign Language (SASL) for Deaf students. As an added bonus, a disc of the sessions in SASL is being compiled for English, Mathematics, and CAT, with plans for it to be distributed to the deaf community in the rest of South Africa via the UFS.
