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.

Incident during FNB Shimlas and FNB Ikey Tigers Varsity Cup rugby match on 13 February 2017
2017-02-13

An incident involving a group of about 20 students of the University of the Free State (UFS) occurred at Xerox Shimla Park on the Bloemfontein Campus tonight.

The incident took place 10 minutes before the end of the match when the group moved through the entrance gates. The group requested the university management to suspend the match and to make a public announcement regarding the Shimla Park Report. The group was addressed at the spectator stands by the Acting Vice-Chancellor and Rector, Prof Nicky Morgan.

“This was an unfortunate incident that could have been avoided by way of earlier engagements. The Shimla Park Report was released to the student leadership structures as well as union and management structures earlier this month. The university management is of the opinion that it was unnecessary to interrupt a public event and has offered to meet with the leadership of the group about the involvement of students in the proposed actions and implementation of the recommendations mentioned in the report, as well as other transformation interventions at the UFS as decided by the Council,” said Prof Morgan.

The UFS gave an undertaking to the organisers of Varsity Cup and made the necessary contingency plans to ensure that the match was not disrupted. This included the presence of the university’s Protection Services and a standby unit of the South African Police Service.

The match was played until full-time, with the final score 22-7 in favour of the FNB Ikey Tigers.
