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.

An intimate send-off party was recently held in Sarah Shannon’s honour by her support group. She is a student from our university and she is heading to present South Africa at the 2011 Pan Pacific Para-swimming Championships in Alberta, Canada from 10-14 August. Here she will be competing in the 50 m and 100 m free-style, and the 50 m and 100 m backstroke, respectively.

Sarah, a silver-medal winner at the Para-Olympic World Championships in Brazil 2009, has set high goals for herself. She has a Bachelors degree in Psychology, has completed her Postgraduate Certificate in Education modules, and she is a motivational speaker to boot. She is also scheduled to start her PGCE practical teaching at the Tswellang Special School in Bloemfontein at the beginning of September 2011. “I love helping people and making a difference, and I would like to work with children with special needs,” Sarah says.

Ms Arina Otto, Manager at our Sports Medicine Clinic says: “We believe in you, Sarah, but mostly we support you all the way.” Sarah is also supported by the South African Sports Confederation and Olympic Committee (SASCOC) and is currently on their OPEX (Operation Excellence) Programme. OPEX sponsored her by ensuring she gets all the medical and scientific support as an athlete.

Sarah swims two hours a day and exercises for an hour on a daily basis.

“We are hoping she does well in Canada so she can be selected for the 2012 Para-Olympic Games,” says Ms Tanya Martin, Assistant Coach: SuperSport Seals Swimming Club.
