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.

More than 200 people, amongst them the Deputy Minister of Higher Education and Training, Prof.  Hlengiwe Mkhize, came together at our university to reflect on the life of ANC Women’s League stalwart Charlotte Maxeke, during the Charlotte Maxeke Memorial Lecture organised annually by the Free State Provincial Government and our university as a lead-up to National Women’s Day on Tuesday, 9 August 2011.

This year was the fourth memorial lecture and Prof. Mkhize delivered the main address under the theme “Women’s access to education, science and technology for economic growth and development in bringing about positive change, living in extraordinary times”

Prof. Mkhize told guests Charlotte Maxeke’s life was too rich and complex to capture during the night and listed many of Maxeke’s achievements during her life and times. These included Maxeke being the first woman to graduate with a science degree from the University of Wilberforce, Ohio.  Prof. Mkhize said Charlotte Maxeke’s science degree was not a personal achievement, because she went back to the people and served by opening the Wilberforce Institute in Evaton, Vereeniging, after her return from the United States.

Prof. Mkhize applauded our university for organising the lecture, saying the university’s commitment was appropriate for the contribution Charlotte Maxeke made to women’s empowerment.  She said government have a huge interest in our university and said the lecture provided an opportunity to dialogue and to use the experience to improve the country’s institutions. Delivering the last part of her address, Prof. Mkhize said she hopes the lecture will lead to great things, with the local community also becoming involved in organising the event.

Dr. Choice Makhetha, Acting Vice-Rector:  External Relations, announced at the event that the university will open a women’s memorial garden on Tuesday, 9 August 2011  to honour women who made a contribution in society.
