Dr Martin Clark
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.

Rhodes professor calls for accountability in teacher education

“Our education system needs quality teacher education.”

This was the message from Prof Jean Baxen, Deputy Dean of Research at Rhodes University in Grahamstown. She delivered the Education Public Lecture on ‘The lives of children, citizenship and teacher education: challenges and opportunities’ at the University of the Free State’s Bloemfontein Campus.

Growing up in White River, the rural areas of Eastern Transvaal (as it was previously known), Prof Baxen took the audience on a journey of the imagination. She shared stories of how she and fellow learners walked miles to get to school and how her son found himself in a situation of being unsure about his own racial identity, questioning what it meant to be ‘coloured’. She also related stories of how teachers are not sufficiently prepared to mediate information on HIV/Aids.

These stories revealed how little teachers cared, and also how difficult and challenging it is for learners to cope in such teaching and learning environments – thus calling for quality teacher education.

She stressed the fact that quality teacher education is needed in South Africa to assist in curbing the challenges children and fellow citizens come across in our broader society. “It is important that, as teacher educators, we should groom teachers to find and understand their identity, sexuality, and also the world they live in. There is an urgent need for us to hold ourselves and others accountable and to not distance ourselves and make it someone else’s responsibility – it is our joint responsibility as citizens,” she said.

We need a pedagogy that would navigate and start formulating a language that we could use to face these challenges, she proposed.
