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.

UFS researcher fills void in South African policing history

late nineteenth century South African policing on the

“I used policing on the Witwatersrand as a lens through which to examine aspects relating to state formation within the South African Republic.”

This is how Dr Cornelis Muller, a postdoctoral fellow in the International Studies Group at the University of the Free State (UFS), described his PhD thesis called Policing the Witwatersrand: A history of the South African Republic Police, 1886-1899. The thesis fills an empirical void in the history of settler colonial policing in South Africa.

His research was also featured in the South African Historical Journal, which is published by Routledge. Dr Muller received his PhD from the UFS during the 2016 Winter Graduation ceremonies. He received a scholarship from the university to conduct his three-year research.

Relationship between police and state examined

The study presents itself as an institutional biography in which the relationship between the South African Republic Police (known as the Zarps), the state, and broader society are examined. The period under investigation was a time when political, economic, and social complexities on the Witwatersrand created tension between South Africa and Great Britain.

An important theme throughout the thesis is the relationship between the police, the mining industry, and the so-called Uitlander community. Crime was also an important contributing factor to the complex relationship that developed between the Zarps and the policed in Johannesburg’s formative years.

“Johannesburg was a town under siege by a variety of crimes which ranged from vagrancy, drunkenness, gambling, and prostitution to robbery, murder, and assault,” said Dr Muller.

Archives in South Africa and Great Britain consulted
“My thesis follows a chronological approach in which various themes accounting for the development of the police on the Witwatersrand are highlighted.” Framed within the bureaucratic and administrative functioning of the Zarps, he examined aspects relating to crime, crisis, and conflict between the police and society. The thesis also details the relationship between the police and Johannesburg’s black community.

As with any historical research, it comprised internal and external source criticism and content analyses of a wide range of archival records.

Dr Muller had the opportunity to visit several archives and libraries in South Africa and Great Britain. “Some of the more important archival collections were assessed at the National Archives in Pretoria.” These included the Archive of the State Attorney and the Archive of the Magisterial District of Johannesburg.

“My study thus adds to scholarship that seeks to provide a more nuanced understanding of the South African Republic’s administrative functioning and internal politics in the late nineteenth century,” concluded Dr Muller.
