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.

Leadership for Change celebrates graduation ceremony
2014-10-15

The Leadership for Change Programme hosted its third annual graduation ceremony on 9 October 2014 at the Centenary Complex on the Bloemfontein Campus.

The event consisted of two segments. The first was aimed at the group who has travelled abroad during the past year. They were presented with special certificates acknowledging the work they have done during their participation in the programme.

The second element of the evening was to wish the 2014/2015 group all of the best for their upcoming travels. This group will be travelling abroad during next year. Of the 250 applicants, the top 32 students were chosen to be part of the Leadership for Change Programme.

Prof Jonathan Jansen, Vice-Chancellor and Rector, said, “I hope you came back with the capacity to distinguish right from wrong – not only through law, but morally as a leader.”

Waldo Staude, Vice-president of the Student Representative Council (SRC), acted as Chair to the evening’s proceedings. He is also an alumnus of this programme.

“This programme has made its mark as we observe the number of leadership positions our students from the programme hold on this campus,” Staude said. “We have eight Leadership for Change students in the SRC for the 2014/15 term.”

The Leadership for Change Programme each year gives first-year students exposure to top universities throughout the world. Its focus is to establish a new campus culture of student relations across boundaries.

Six cohort groups – of between five to six students each – will visit universities on three different continents in January 2015. Each group will be accompanied by a UFS staff member serving the role of mentor.

The universities they will be visiting (according to continent), are:

 USA
Cleveland State University
University of Minnesota
University of Vermont 

Europe
The Netherlands: Vrije University in Amsterdam
Belgium: University of Antwerp and Ghent University 
 
Asia
Japan: International Christian University
