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.

Zakes Mda honoured at UFS Summer Graduation
2013-11-21

 
The awarded author, Dr Zakes Mda, received his honorary doctorate at the University of the Free State at the December Graduation Ceremony. Pictured here with him is Dr Khotso Mokhele, Chancellor of the UFS.

On Thursday 5 December 2013, the University of the Free State (UFS) will award more than 300 degrees and qualifications during the Summer graduation at the Bloemfontein Campus.

The graduation will take place during two ceremonies in the Callie Human Centre, where master’s and PhD degrees will be awarded during the first ceremony at 10:15 and diplomas, certificates and undergraduate qualifications awarded to students from the School of Open Learning and the Faculty of Health Sciences at 14:30.

An honorary doctorate from the UFS will also be bestowed on the author, Dr Zakes Mda, during the morning ceremony.

Dr Mda is a South African literary icon and public intellectual with extraordinary local and international influence. Mda’s contribution to world literature and contemporary South African public life resonates powerfully with some of the fundamental principles of the Academic and Human Projects articulated in the strategic thrust of the University of the Free State, which makes him an ideal candidate for an honorary doctorate from our university.

Some of his most famous works include Ways of Dying, Heart of Redness, The Madonna of Excelsior, The Whale Caller, Cion, Black Diamond and his recent memoir: Sometimes There is a Void: Memoirs of an Outsider.

The Springbok rugby player, Jannie du Plessis, will address graduandi during both ceremonies.
