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.

Prof Gustav Etienne Visser (43) is Professor in Human Geography at the University of the Free State. He has been with the university’s Geography Department since January 2002 and became a full professor in 2009.
Visser completed his MA in Geographical Research at the Stellenbosch University in 1996 and finished his PhD in Geography at the London School of Economics and Political Science in 2000. His thesis was titled: Spatialities of social justice: reflections on South African Cities.

Visser was a Post-doctoral Fellow at the School of Geography, Archaeology and Environmental Studies at the University of the Witwatersrand before his appointment at the UFS. He now teaches Urban Geography to third-year students and Tourism and Development to MA students.

His research interests so far have been Identity-based consumption and urban morphological change, Tourism and development nexus and Critical reflections on South African Geographical Research.

Visser’s publications summary is as follows:

- Four books – edited collections
- 28 book chapters
- 71 refereed articles
- Nine academic commentaries and research notes
- 14 research reports
- and 38 conference papers

His latest research on how people’s leisure time influences our urban spaces, is fundamentally relevant to everyday life.

“We tend to forget to think about it, but how people spend their leisure time is part of their lifestyle,” says Visser.“ And our urban surroundings are influenced by the lifestyles of its inhabitants.”

When asked about his own leisure time and activities, Visser humorously responds “There is no such thing.”

However, he is passionate about eating, cooking and wine.
“I must also watch a series every day – Dexter is definitely my favourite.
“Furthermore, I also travel abroad for about three months of the year, which is mainly for my research concerning urban spaces.”
