Dr Martin Clark
Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

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.

Training in critical medical skills receives preference at the UFS
2015-07-24

The UFS bought a new simulator for surgeons to learn how to perform laparoscopic operations. During the launch of the simulator, Dr Mathys Labuschagne (left), Head of the Clinical Simulation and Skills Unit, illustrates to Prof Gert van Zyl, Dean of the faculty, how the simulator works.

The Clinical Simulation and Skills Unit in the University of the Free State (UFS) Faculty of Health Sciences purchased a new laparoscopic simulator for R1.2 million recently. The simulator will be used to teach postgraduate medical students how to perform laparoscopic surgery. The UFS is currently the only university in the country, and one of only two institutions in South Africa, that own such a simulator.

The Lapsim simulator, from Surgical Science in Sweden, is a highly sophisticated computerised tool for the training and improvement of laparoscopic surgical skills in postgraduate students within the surgical disciplines.

“The purpose of a simulator is not to replace training on patients, but to help registrars in acquiring basic laparoscopic surgical skills,” says Dr Mathys Labuschagne, Head of the Clinical Simulation and Skills Unit.

These skills include depth perception, hand-eye-coordination, instrument handling, precision and speed, which are essential before operations can be performed on patients.

Prof Gert van Zyl, Dean of the Faculty of Health Sciences, says this simulator is very important for the UFS to train registrars more effectively in theatre work.

“Not only registrars will benefit from this, but qualified surgeons may also make use of it to improve their skills.”

The simulator is pre-programmed for different medical conditions that laparoscopic surgery is traditionally used for. Programmes can be selected for procedures such as sterilisation, cholecystectomy (gall bladder removal), endometriosis, etc. The simulator even makes it possible simply to practise eye-hand coordination, and to apply stitches internally.
