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 management teams of the University of the Free State and the Vista University Bloemfontein campus set the wheels rolling for the incorporation of the Vista Bloemfontein campus into the UFS.

The incorporation process will be dealt with in two phases. The first phase would be preparing for a possible incorporation on 1 January 2004, including possible streamlining and review of programmes. The second phase would be part of developing the long term vision or optimal reconfiguration of the Vista facility (within the UFS as a multi-campus institution) in the interests of higher education in the Free State and the communities surrounding the two campuses in Bloemfontein.

At a meeting at the UFS both parties reached consensus about the process and set about establishing task teams to deal with critical issues, such as governance and management, financial management, human resources, information systems, library services, student support and administration, academic planning and academic programmes.

Prof Talvin Schultz, Head of the Vista Bloemfontein campus, committed this campus to making the process of incorporation into the UFS an exemplary process. UFS Rector Prof Frederick Fourie said the Free State should continue its tradition as a province where things happen and where higher education transformation has proceeded faster than elsewhere in the country.

Both emphasised the need for an inclusive process of consultation with staff, students and the community on key aspects of the incorporation.

They indicated that all planning should take into account a possible date of incorporation of 1 January 2004, pending finalisation by the respective Councils. The Councils of both institutions need to give feedback to the Minister of Education on the date of incorporation by the end of June, and the task teams must deliver an initial report on progress before then.
