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.

HIV/AIDS could kill 20% of southern Africa’s farm workers by 2020
2008-09-27

HIV / AIDS is claimed to account for 40% - 50% of infections in the workforce in some labor-intensive industries. This means that every farmer will have to replace up to 50% of his workforce within the next 10 years.

This was said by Mrs Estelle Heideman (pictured) of the Faculty of Natural and Agricultural Science at the University of the Free State (UFS) at the launch of a DVD about a project to equip farm workers with knowledge and skills regarding HIV / AIDS.

Mrs Heideman was quoting the research findings of Agrimark Consultant, Johan Willemse, and added that farm workers, because of low literacy levels, remoteness of the areas in which they live and the distances to health care facilities, are often forgotten when it comes to HIV/AIDS prevention and care programmes.

This weekend Mrs Heideman leaves for New York City to take up a scholarship awarded to her by the University of Columbia and the University of California, Los Angeles (UCLA) to participate in the M-A-C AIDS Sponsored Leadership Programme.

The leadership Initiative provides a structured support program to enable participants to exchange best practices in the approach to HIV prevention that can be adapted to local circumstances. At the conclusion of the program the Leadership Initiative will, amongst other benefits, provide funds for Fellows to carry out their prevention program in South Africa.

Such a program was already carried out from February to May this year as part of the Lengau Agri Centre’s Farm Project in collaboration with the Chief Directorate Community Service at the UFS on the farms Slangfontein, Dwarsrivier and Pypersfontein in the Philippolis district.

According to Mrs Heideman, who is the co-coordinator of the project, the aim of this project was to equip farm workers with knowledge and skills regarding HIV/AIDS so that they can take control of their lives and make quality decisions.

“A major advantage of working with farm workers is that the whole family is included in the session and this ensures that all generations get the same message”, she said.

At the end the feedback from the farm workers about the programme was positive. “Many said they had tested for HIV and will continue to do so to ensure that they would be around to see their children grow up”, said Mrs Heideman.

Copies of the DVD can be obtained from Estelle Heideman (0828211230) or Tarryn Nell (0832573843).
