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 to monitor the use of ARV-drugs on pregnant women and children
2004-12-08

The University of the Free State (UFS) is to establish a Pharmacovigilance Centre that will monitor the effects of Anti-Retroviral (ARV) drugs on HIV positive pregnant women and children starting early in the new year.

The UFS is one of only two institutions chosen by the Minister of Health, Dr Manto Tshabalala-Msimang, to establish such an ARV monitoring centre.

The other centre will be based at Medical University of South Africa (MEDUNSA) and will concentrate mainly on monitoring the effects of the drugs on adults.

“The establishment of the UFS’s Pharmaconvigilance Centre forms part of government’s Comprehensive Plan on HIV and AIDS, often termed the roll-out plan for ARV drugs. The centre’s primary responsibility will be to specifically monitor the use of these drugs in pregnant women, and children under the age of 13,” said Prof Andrew Walubo of the UFS’s Department of Pharmacology.

“Although most of the side effects of ARV drugs have been identified in other countries, it has now become critical to identify the side effects amongst the South African population. This is important because many people will be exposed to the drugs within a short time. Our aim is so identify the most common side effects and make recommendations for the prevention thereof. The centre will help in detecting the risk of using anti-retroviral drugs in pregnancy and children, and prevention of adverse drug reactions,” said Prof Walubo.

According to Prof Walubo 12 drugs will be monitored – these drugs will be selected according to the patient’s profile.

The centre will comprise of two components: A pregnancy registry, which will focus on a new-born child up until two months and a pediatric registry, which will focus on children who are born of mothers who used ARV drugs and children using ARV drugs.

According to Prof Walubo, the Pharmaconvigilance Centre will also be responsible for offering relevant technical advice, training and selected research on ARV drugs in these patients.

The centre will be fully sponsored by the national Department of Health. It will be based in the UFS’s Faculty of Health Sciences, Department of Pharmacology, and will be run in collaboration with experts from different departments in the faculty.
