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.

“You don’t have to be in New York or any big city in the world to establish a cardiovascular centre that delivers work of world standards. I’ve learned that extraordinary things are achieved by ordinary people who apply themselves accordingly. This research centre is a South African solution to a continental challenge”.

These were the words of Prof Robert Frater at the opening of the new Robert W M Frater Cardiovascular Research Centre in the Department of Cardiothoracic Surgery at the University of the Free State (UFS) School of Medicine.

The centre, one of only two of the kind in the country, will focus on bioengineering and cardiovascular research. It was opened on Wednesday 18 November 2015 in the Francois Retief Building on the Bloemfontein campus.

The centre is named after Prof Robert W.M Frater in recognition of his vast contribution to the UFS. He is internationally recognised for his outstanding academic, clinical, and scientific contributions to cardiac surgery. Prof Frater has also been actively involved in research activities of the Department of Cardiothoracic Surgery for the last 10 years. In 2011, he received an honorary doctorate from the UFS.

Under the leadership of Prof Francis Smit, head of Cardiothoracic Surgery, the department has been described as a dynamic unit at the forefront of meeting the different changes in Southern Africa while maintaining an excellent clinical and academic track record.

At the opening, Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, thanked Prof Frater for his presence at, involvement in, and support of the UFS. “I am looking forward to working in collaboration with the department to make this university a research centre of excellence in the continent”, he said.

The centre has existing endeavours already in operation, including Population projects, Clinical studies, and Clinical pathology, to name three. In collaboration with the Central University of Technology, the University of Stellenbosch, and Charite University of Berlin, among numerous others, the centre will be an appropriate help to an African challenge.

Its introduction promises advanced research outcomes with the potential to make the Department of Cardiothoracic Surgery a world-class competitor.
