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.

Freedom of religion, a constitutional right and area of global concern

Freedom of religion is enshrined in the South African Constitution, states that everyone has the right to freedom of religion, which more specifically entails the freedom of conscience, religion, thought, belief and opinion. It makes provision for the protection of religious communities in South Africa. Consequently, the maintenance and protection of such a right is of fundamental importance.

Prof Shaun de Freitas, Associate Professor of Law at the University of the Free State (UFS) specialises in constitutional law, with a specific focus on the right to freedom of religion, and has produced several publications in the field. The latest is titled “Transcending the Private-Public School Divide in the Context of the Right to Freedom of Religion in South Africa”, Chapter 19, in Religious Freedom and Religious Pluralism in Africa – Prospects and Limitations published by Stellenbosch University in 2016.

Prejudice a challenge in all societies
There are numerous challenges faced by religious groups around the world concerning prejudice, association with terrorism and political power and influence. Therefore, research in this field becomes important in helping to uphold the rights and freedoms of religious minority groups, to be able to foster understanding between communities.

Balancing responsibility and religious rights
His current focus is on challenges that have arisen in South Africa, more specifically pertaining to the right of medical practitioners to object conscientiously towards participating in certain medical procedures, the parameters of freedom related to religious associations and the inclusion of religious expression in public schools. These matters are also relevant to many other parts of the world (including, ironically enough, those democratic societies that endeavour to make diversity flourish).
