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.

Researchers explore gender-based violence at schools in Southern Africa

Violence in schools, especially gender violence, has been a much explored and debated topic. But researchers at the University of the Free State (UFS) are now also exploring the link between gender, diversity and violence in schools in Southern Africa.

This study – a first of its kind – received funding from the United Nations Educational, Scientific and Cultural Organisation (UNESCO) and will investigate how the perception of ‘different’ is a contributing factor to violence in schools.

This UNESCO-funded study, in collaboration with Hivos, GALA and the Government of the Netherlands, will involve schools in Botswana, Lesotho, Namibia and Swaziland.

Prof Dennis Francis, UFS Dean of Education and principal researcher in this study, says children and youth around the world are exposed to violence in and around educational settings. “This does not only undermine a child’s rights to quality education, but also the capacity of the education sector to train future citizens who will respect each other regardless of differences.”

Prof Francis says although girls are the most vulnerable targets of GBV, boys can also be targets, as evidence reveals that many children and youths who are perceived as different in terms of gender, are often victims of violence in school.

“Education is the most significant means of fostering social inclusion, promoting individual rights and realising the full potential of all young people, including those perceived as different. This project is aimed at assisting government, policy makers and professionals in the education sector, as well as civil society organisations and other key stakeholders in Southern Africa to create educational policies and practices that promote safe schools for all youths.”
