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.

The mysterious origins and problematic significance of the Postamble
2014-10-20



Prof André du Toit (UCT) and Prof Pieter Duvenhage (UFS)
Emeritus professor from UCT’s Department of Political Studies, Prof André du Toit, delivered a presentation at the Bloemfontein Campus on 14, 15 and 16 October 2014 respectively. His presentations gave an in-depth exploration of the Postamble as founding text of the South African Truth and Reconciliation Commission (TRC).

This event was hosted by the Institute for Reconciliation and Social Justice, in collaboration with the Department of Philosophy.

Prof Du Toit’s papers were entitled:
•    A Need for Truth: Amnesty and the Origins and Consequences of the TRC Process.
•    Tracking down a belated and inconclusive amnesty pact: The obscure origins and problematic significance of the 'Postamble' as founding text of the TRC process (Part 1 and 2).

In his presentations he explored how the text of the Postamble came to be written. He also scrutinised the respective contributions of those who were involved in drafting the text. The significance of the Postamble – as it is understood in its historical context – was also a point of discussion.

Prof Du Toit raised some thought-provoking questions during the three days. What is the relation of the amnesty provision of the Postamble with the subsequent TRC amnesty process? How did a text without any particular reference to a truth commission come to function as founding text and discursive framework for the TRC?

He also investigated some of the main problems with the history and significance of the Postamble, as well as its mysterious origins. In addition, Prof Du Toit conducted a critical analysis of a set of newly-identified drafts of the text.

One of Prof Du Toit’s most substantive inquiries, though, was into the question: Was the amnesty provision of the Postamble the product of an underlying amnesty ‘pact’ between the NP government and the ANC?
