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.

Kovsies goes green
2012-08-22

The university will soon be hosting its first Green Festival that will focus on protecting and sustaining natural resources for current and future generations.

The aim of this festival is to demonstrate to students, learners and the broader community that any act, no matter how small, makes a difference and that each individual must play his or her role in creating a sustainable environment and caring for the earth.

Busi Madikizela, SRC member: Student Development and Environmental Affairs, said, “We have a moral obligation to do this as it not only teaches our students about sustainable living, but also sets an example for the communities that the university forms part of and serves.”

The festival takes place on Saturday, 8 September 2012 and will be filled with fun and games.

The university has invited Grade 9 to 11 learners from 41 schools around Bloemfontein to participate in cleaning up the city. The learners and Kovsie students will clean the streets around the Bloemfontein campus. The clean-up teams will meet on the campus in the vicinity of Mooimeisiesfontein, whereafter the rubbish collected will be sorted and taken to the Rat Race recycling company.

Other activities for the day include a Green Quiz that will help educate learners and students about green issues. Coca Cola will sponsor the prizes for the festival, as well as the food and drinks for all the learners invited to the festival. The learners will visits 20 stalls and exhibitions of sustainable green materials and organic food on the Red Square. Documentary movies with green themes on environmental issues will be screened.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university, has urged everyone to participate in the Green Festival.
