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.

Dr Johann Rossouw receives 2015 ATKV SA Academy Award for his work in Philosophy

Dr Johann Rossouw

Dr Johann Rossouw, Senior Lecturer in the Department of Philosophy at the University of the Free State, was recently selected as one on the winners of the 2015 ATKV SA (Afrikaanse Taal- en Kultuurvereniging) Academy Awards. Dr Rossouw was one of only six winners that were honoured nationwide for their academic articles.

ATKV SA Academy Award

This award has immense value for Dr Rossouw, since “it’s proof that original endemic thinking is still valid today, despite the massive pressure on Afrikaans. It also undermines the parochial view that English is the only language in which thought takes place.”

The annual ATKV SA Academy Awards honours six Afrikaans articles that are published in accredited journals in a specific year. Four of the prizes are awarded for articles in the Humanities and two for articles in the Natural Sciences. The South African Academy for Science and Arts handled the selection process.

First theological-philosophical criticism on Stiegler

Dr Rossouw was honoured for two articles in the Humanities that were published on Litnet Academic. The articles deal with the theological-philosophical approaches of the first two volumes of Bernard Stiegler's influential La Technique et letemps (Technics and Time) trilogy. “Stiegler wrote the trilogy in conversation with Heidegger's Being and Time,” Dr Rossouw says. “With Heidegger claiming that the technique closes off our world, Stiegler argues that the technique helps to unlock and establish our world as a unique kind of memory in certain conditions. That is why Stiegler argues that the technique is the life lived through other means than life itself.”

The essence of Dr Rossouw's criticism against Stiegler is that he “pursues Christianity through means other than Christianity itself. To my knowledge, this is the first theological-philosophical criticism on Stiegler, and to all intents and purposes the first criticism on his work, with one or two exceptions.”
