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.

The Faculty of Health Sciences of the University of the Free State (UFS) has, as part of its commitment to student and community development, established a student residence in the town of Trompsburg in the Kopanong Local municipality, Xhariep District municipality in the Southern Free State. The Faculty officially opened the Faculty of Health Sciences Rural Community Initiative on 14 and 15 June 2017. The memorial plaque was unveiled by Prof Gert van Zyl (Dean of the Faculty of Health Sciences) and Prof Francis Petersen (Rector and Vice-Chancellor of the University of the Free State)

The importance of the residence

The goal of the ‘Kopanang le fodise – Unite to heal’ programme is to develop a community-centered collaborative framework for sustainable, holistic healthcare and social development incorporated in the curricula of the Faculty.

Background of the project

During 2016 a total of 324 fourth-year students of the Faculty have each spend at least a week in interprofessional groups in primary healthcare facilities in the Kopanong municipality on a Community Based Education, Interprofessional Education (CBE-IPE) platform in Trompsburg and Springfontein.

To facilitate student rural placement the former Midway guesthouse currently includes seven (7) facilitator units with on suite bathrooms, two (2) fully equipped lecture facilities, a recreation room and a library with computers and internet access. The newly developed student residence has 10 apartments that can each accommodate six (6) individuals. A housemaster resides on the premises and acts as manager of the facility. All areas of the residence are Wifi covered and 24h security service is in place.

The ceremony was attend by the following partners
