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.

National 3MT competition held at UFS

From Neanderthal hybrid children to eating corn silk as a way of managing kidney diseases, the National Three Minute Thesis competition (3MT) captivated the mind.

“We brought the competition to South Africa and hosted the local, regional, and national competitions for the past few years,” said Dr Emmie Smit, organiser of the event. It is an opportunity to raise the profile of postgraduate research and to develop a cross-disciplinary student community to effectively communicate research to a wide audience. The event was founded by the University of Queensland, Australia. The third national 3MT competition took place at the University of the Free State (UFS) on Friday 24 March 2017.

Three minutes and one slide
During the competition, participants had three minutes to explain their master’s or doctoral research and one static PowerPoint slide could be used. “It is very important that this slide works for you. There must be some way the information on the slide connects to what you present,” said Dr Henriette van den Berg, Director of the Postgraduate School at the UFS.
 
Winners grateful for opportunity
“It is an honour and a drive. It is very nice to have this sort of thumbs up,” said Kerryn Warren, winner of the Science category. Her research title was, What did a Human-Neanderthal Child Look Like? “I have been looking at the hybrids between different species and subspecies of mice in order to use them as a model to find out what human hybrids looked like.”

The presentation by Andrew Verrijdt, winner of the Humanities category, entitled Hiding in the Deep: Anonymous Websites for Paedophiles on the ‘Darknet’, gave a glimpse into the mysterious and dangerous realm of the dark web. “I am grateful for the opportunity. Primarily because I think it’s an important topic, and society will benefit by getting the word out there as it is a sensitive topic,” he said. The two winners, both from the University of the Cape Town, won R15 000 each.  A further R30 000 of prize money went to the four runners-up.
