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.

Publication on indigenous knowledge systems
2005-10-21

UFS launches most comprehensive publication on indigenous knowledge systems
A unique collection of essays on Indigenous Knowledge Systems (IKS) was launched yesterday (20 October 2005) by the University of the Free State’s (UFS) Programme of Africa Studies.

The essays are published as a special edition of INDILINGA, the African Journal for Indigenous Knowledge Systems and is an outcome of the colloquium on Indigenous Knowledge Systems that was presented last year by the UFS Director of Africa Studies in cooperation with the National Research Council.

“The amount and diversity of materials on IKS brought together under one cover is unique as there are no other South African publications of this magnitude on this issue.  It contains papers of international experts on IKS such as Prof Fritz Wallner from Austria and Prof Gayatri Spivak, foremost postcolonial theorist from India,” said Prof Philip Nel, Director of Africa Studies and guest editor of the publication.

“The publication is a rich source field for students and scholars to exploit because most of the sources quoted in the articles are recent, fresh and relevant.  The contributors are largely people responsible for managing, fostering and studying IKS in a responsible manner,” said Prof Nel.

“An added value of the publication is the inclusion of the policy document on IKS that was adopted by Cabinet in November 2004,” said Prof Nel.


“Millions of people in South Africa are faced with the painful choice of abandoning their heritage.  In this choice, the study and management of IKS has a major role to play; on the one hand, to encourage as much assimilation of traditional knowledge as possible into the modern systems, and on the other hand to provide a “language” and a “grammar” for indigenous people through which they can access modernity,” said Prof Nel.

The IKS debate involves questions of African identity, protection of indigenous communities and practices, political aspects as well as the scientific integrity of the enterprise. 

The publication displays the range of burning questions that have to be resolved in this field such as mainstreaming IKS in academic debate and practice, recognition and protection of the knowledge holders, bio-prospecting and bio-piracy, bio and ethnic healing, lack of textbooks and field manuals, etc and will prove worthwhile for future researchers.

 “One of the main reasons for publishing this volume is the fact that IKS should be studied not only to provide a sense of pride in the past, or  to engender respect for indigenous peoples, but also to enable people in indigenous mind sets to make a better transition into the world of science and technology,” said Prof Nel.

The guest speaker at the launch was Dr Otsile Ntsoane, acting Director of IKS at the Department of Science and Technology.  In his speech Dr Ntsoane stressed the symbolic and concrete value of the publication.  “The publication can have a great social impact and the research results can contribute to chancing the economic landscape of South Africa,” he said.

The publication can be purchased at R150 per copy.  For more information, Ms Steffi Cawood, Programme Coordinator for Africa Studies at the UFS can be contacted at (051) 401-2614.
