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.

UFS Ground Studies Laboratory receives accreditation to international standard

The Institute for Groundwater Studies (IGS) Laboratory at the University of the Free State is on equal footing with international testing labs. With its accreditation in March 2016 by SANAS (South African National Accreditation System), the IGS Laboratory now officially meets global standards.

Quality of water

The IGS Laboratory mainly analyses the quality of water samples. When it was originally established in 1989, the lab’s central function was to conduct testing for researchers at the institute itself. “After the public and water boards realised their need to analyse water samples, the IGS Laboratory expanded to deliver a service to these clients,” says Lore-Mari Deysel, Deputy-Director of the institute.

Since suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited, the IGS initiated the accreditation process.

Accreditation to international standard


In order to be deemed technically competent and able to receive accreditation, labs must meet the ISO/IEC 17025 standard. ISO/IEC 17025 was first issued in 1999 by the ISO (International Organization for Standardization) and the IEC (International Electrotechnical Commission).According to Deysel, this is the single most important standard for calibration and testing laboratories around the world.

“Laboratories that are accredited to this international standard have demonstrated that they are technically competent and able to produce precise and accurate test and/or calibration data. Furthermore, it demonstrates that the university has the capacity to supply valuable and reliable services alongside the academy,” Deysel says.
