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.

Cedric Nunn’s latest photographic exhibition, Unsettled: One Hundred Years War of Resistance by Xhosa Against Boer and British, opened on 25 May 2016 at the Johannes Stegmann Art Gallery of University of the Free State, and will run until 17 June 2016. Since 2014, the exhibition has travelled through South Africa and the USA as well as Germany.

The photographer, documentary film-maker, and artist’s photographic journey was launched in the early 1980s in Durban. In 2011, he won the first FNB Joburg Art Fair Award.

Narratives of the victors and the vanquished

Unsettled deals with the nine wars that Xhosa people were subjected to between 1779 and 1879 in their fight against Afrikaner and British colonial settler forces. Nunn’s art seeks to instigate social change, and highlight lesser-seen aspects of society.

The work emanated from his awareness of a notable gap in the telling of this piece of South African history, as well as the fact that, to date, little has been done to memorialise these acts of colonial aggression and Xhosa resistance. He decided to document the land where these struggles took place.

“Through revisiting this painful past in the contemporary scenes of today, this work attempts to place the present in its factual context of dispossession and conquest,” said Nunn.

Unsettled
forms the first component of what will be a trilogy. The next component will address the legacy of colonial dispossession through “bringing ‘the first inhabitants’ back into the picture by giving a select number of self-describing Khoi, Griqua, and San or Bushmen a contemporary face and presence”. The final component will look at slavery.
