Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

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 hosts colloquium on technological higher education

Description: Technology colloquium Tags: Technology colloquium

Prof Lew Zipin, Prof Sechaba Mahlomaholo,
Prof Marie Brennan and Dr Milton Nkoane,
attended the Faculty of Education’s colloquium
on the field of technological higher education
and its contribution to the knowledge society,
at the UFS Bloemfontein Campus. 

The University of the Free State’s (UFS) Faculty of Education, in collaboration with the Research and Development Unit from the Central University of Technology (CUT), hosted a colloquium on the field of technological higher education and its contribution to the knowledge society. Prof Marie Brennan and Prof Lew Zipin, both from Victoria University in Melbourne, Australia, presented the keynote addresses of the colloquium.

The past, present and future
The current fees protests in South Africa have caused universities to rethink and strategise new ways of delivering knowledge. Prof Brennan cautioned that when moving towards technological solutions for teaching, a crucial balance between past knowledge and practices and present and future knowledge and practices needed to be maintained.
“Knowledge is always dynamic, always generated from live problems, and therefore always relies on social interactions. Face-to-face interaction is removed by intense interaction with technology. If knowledge is presently linked to technology, we as academics must be able to move it. However, we should not neglect the indigenous knowledge that was generated through face-to-face interaction,” said Prof Brennan.
She purported that a reconnection between social relations and technology was important but to achieve this, a clearer pedagogical understanding of knowledge production was needed.

Never simplify complex problems

Prof Zipin said academics were constantly seeking complex problems and therefore could not reduce the complexity of a problem to simplify it for students entering the higher education space.
“We need to become a knowledge society. Ideologies often sway us not to look at the complexities of knowledge otherwise these ideologies would not be persuasive,” said Prof Zipin.

Is the technological move counterproductive?
Prof Zipin also cautioned that the move towards technological means for transferring knowledge had its own drawbacks. Institutions are a knowledge economy and its product is human capital. However, producing graduates who catered only to a technological society created downward mobility.
“People’s jobs are replaced by technology. This causes wages to decrease significantly because of structural inequalities, the move towards tech-based schooling should be done cautiously,” said Prof Zipin.

Simplicity not the ultimate sophistication
Prof Zipin concluded by stating that higher education had a responsibility to give its students the best possible future, this could be done by creating hegemonic relationships between institutions of higher learning, government and the private sector. Academics needed to fill the gap and apply their knowledge by applying complexity to social issues and allowing the complexity of these issues to flourish, the professor said.
