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.

Two significant political events: the murder of an unarmed protester, and school children forced out of school sparked the idea to write a book on community protests.
The book, Civil strife against local governance: Dynamics of community protests in contemporary South Africa, by Dr Sethulego Matebesi, gives an academic account of service delivery protests in South Africa.

Research address protests in different communities
“The focus of my book is on community protests directed against municipalities in both predominantly black and white communities,” Dr Matebesi, senior lecturer in the Department of Sociology at the University of the Free State, said. The funding for the book was received from the National Research Foundation and the Erasmus Mundus EU-Saturn Scholarship.

Informs literature on service delivery protests

The struggle against municipalities reaches across geographic and demographic boundaries, but the violent turn of protests in black communities in contrast to white communities has become somewhat of a hegemonic account by scholars. “The book connects the critical issue of community protests with the equally precarious issue of political trust in local government,” Dr Matebesi said. Case studies in the book are indicative of significant shifts in community protest – thus making it timely. Dr Matebesi said: “The book informs the growing literature on community protests and also fills an empirical void by including protesters in residents’ associations.”

“The book is a personal milestone and
the single greatest return on the
sacrifices made over the past 4 years.”





Personal milestone worth the sacrifice
Research was conducted between 2012 and 2015, whereby two case study sites were selected in four provinces to account the different tactics used. “The book is a personal milestone and the single greatest return on the sacrifices made over the past four years,” Dr Matebesi said.
