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.

First Beyers Naudé lecture held at UFS' Qwaqwa Campus
2011-03-15

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), delivered the first lecture to celebrate Dr Beyers Naudé’s life and legacy in a series of public lectures at the UFS’ Qwaqwa Campus.

In his address, Prof. Jansen warned that South Africa cannot afford a genocide of which the seeds are sown by those who continue to use racist and derogatory terms against their fellow citizens.
 
“The present debate in the media that was started by Jimmy Manyi’s comments and subsequently followed by the column by Kuli Roberts in the Sunday World about what they called ‘coloureds’ in the Western Cape, is not a ‘coloured’ debate. It is a South African debate and the silence from certain quarters of our society is disturbing,” said Prof. Jansen.
 
He pointed out that all countries that had previously experienced genocide had started in the same way when “those who were in power chose to keep quiet when wrong and dangerous statements were being uttered”.
 
“This country needs courageous citizens and leaders like ‘Oom Bey’ who sacrificed all the privileges and opportunities of being an Afrikaner in apartheid South Africa. He courageously stood up against his own people by declaring apartheid as evil and un-Christian. That’s the consciousness that all Kovsie students and the entire community must strive for.
 
We want Kovsie graduates who are also graduates of life. We want Kovsie graduates who will have the conscience to question wrong-doing, irrespective of who did it, and irrespective of where wrong-doing is being done. That’s the Kovsies we will all be proud of,” Prof. Jansen concluded. 
 
The lecture was preceded by a student debate on the theme and was the first of the four in the 8th annual Beyers Naudé Memorial Lecture Series themed Conscience and courage in the struggle for justice. The second lecture will be presented by Prof. Kwandile Kondlo, who heads the UFS’ Centre for African Studies, on 28 April 2011, and the main event is scheduled for 9 September 2011.
