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.

Arts Festival Rally promises to be great fun
2009-05-20

The annual Amazing Rainbow Rally, presented by the Department of Paediatrics and Child Health and UFS Marketing, will take place on Friday, 17 July 2009 during the Volksblad Arts Festival on the Main Campus of the University of the Free State (UFS) in Bloemfontein.

This year all the checkpoints will be on the campus and around the Arts Festival grounds. Corporate companies in Bloemfontein and departments at the UFS may still enter teams and checkpoints.

The closing date for entering teams is 26 June 2009. A team consists of two team members who must work together to complete a route with various checkpoints. The team, who finishes first after having successfully completed all the tasks, is the winner. Last year, Dr I Babst en Dr L Solomon from the Department of Paediatrics and Child Health were the winners of the Rally.

The closing date for entering a checkpoint is 17 June 2009. Teams must complete tasks at every checkpoint before proceeding to the next checkpoint. The company sponsoring the checkpoint will also be responsible for handling the activity at the checkpoint.

The “Arts Festival” Rally promises to challenge teams physically, mentally and even artistically. Festival goers will also have the opportunity to see what teams get up to and how their favourite team is doing.

The Rally will be presented for the fifth time in 2009. The main goal of this year’s Rally is to raise funds for the Department of Paediatrics and Child Health’s “Beds of Hope Campaign”. This campaign seeks to increase the number of intensive care beds in the paediatric and neonatal wards. Currently around 250 children and babies in central South Africa cannot receive the life-saving care they need because of a lack of facilities.
