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.

SA-YSSP scholars attend high level colloquium with policy makers and research stakeholders

Scholars taking part in the 2nd Southern African Young Scientists Summer Programme (SA-YSSP), attended a one-week seminar hosted by the African Doctoral Academy at the Stellenbosch University, which concluded with a colloquium at the Stellenbosch Institute for Advanced Study.

This was part of the final leg of their three-month stay and studies at the University of the Free State.

This seminar was a capacity development intervention with the purpose of equipping SA-YSSP young scholars with the skills to communicate their research work effectively with different audiences.

The 36 scholars were hand-picked from some of the world’s most promising and top researchers to take part in the novel three-month programme for advanced doctoral candidates. Their research interests closely aligned with the Department of Science and Technology’s (DST) grand challenges and the International Institute for Applied Systems Analysis’ (IIASA) current research programmes regarding global environmental, economic and social change.

The SA-YSSP is an initiative that contributes to the establishment, growth and enhancement of high-level strategic networks internationally. At the same time it develops capacity in systems analysis at the PhD and supervisory levels through research conducted in the areas of the Department of Science and Technology’s (DST) grand challenges.

At the colloquium, students were expected to showcase their work and research according to their various fields of expertise. High-profile policy makers and policy funders, as well as academia and fellow researchers judged and critiqued the work.

Dr Priscilla Mensah from the UFS and co-director of the programme, says it is important for the young scientists to frame their findings in a way that will be relevant to policy makers and the public at large.

“The partnership with the African Doctoral Academy was crucial in this regard since it is a capacity development entity aimed at strengthening and advancing doctoral education, training and scholarship on the African continent. The objective of this week-long capacity strengthening intervention is to equip the young scientists to be able to communicate their research effectively with different audiences, including potential funders and policy makers.

“I am convinced that the young scientists will no longer view policy makers as abstract entities, but as stakeholders who must be engaged to facilitate implementation of evidence-based policy.”

Dr Aldo Stroebel, Executive Director: International Relations and Cooperation, National Research Foundation, says the purpose of the colloquium is to bring together different sectors in one room to look at different challenges holistically, with an emphasis on systems analysis for a common goal.

The SA-YSSP forms part of an annual three-month education, academic training and research capacity-building programme jointly organised by IIASA, based in Austria, the National Research Foundation (NRF) and the DST. IIASA is an international research organisation that conducts policy-oriented scientific research in the three global problem areas of energy and climate change, food and water, and poverty and equity. South Africa’s engagements with IIASA, specifically with regard to the SA-YSSP, relate primarily to the DST’s Ten-Year Innovation Plan.

The UFS is the first institution outside Austria to host the summer programme. Researchers in the programme are, among others, from South Africa and the rest of the African continent, the USA, the Netherlands, India, Hungary, Austria and Germany.
