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.

Prof Johan Spies learns about much more than genetics in Argentina
2014-04-23


People who attended the course enjoyed Argentina and its traditions very much.

Prof Johan Spies from the Department of Genetics visited Argentina, where he and Dr Carlos Acuna (Universidad Nacional del Nordeste, Corrientes, Argentina) presented a course for doctoral students and staff of Cerzos-Conicet Bahia Blanca (something like the equivalent of South Africa’s NRF) and Universidad Nacional del Sur, Bahia Blanca. Prof Spies presented chromosomal evolution and its effect on fertility, while Dr Acuna took care of apomixis.

Bahia Blanca is a city with a population of almost the same as that of Bloemfontein. The city lies at the mouth of the Naposta River, which almost forms a delta where it flows into the sea. Bahia Blanca (white bay) derives its name from the salt deposits that lends a white colour to the beaches.

The people are very friendly and one soon learns to extend a long arm in greeting. Otherwise you are stuck with an ‘Ola’ while men and women alike will grab even a complete stranger to plant a kiss on your cheek. For people who places great value on personal space, this friendly gesture is not always as welcome!

Barbeque is a choice dish and is usually in the form of beef rib. “It was great (especially if you shut your eyes and ignore the scrumptious fat and future heart attacks)! With the rib they usually had blood sausage and very tasty pork sausage on the grid. Everywhere people are sipping, through a silver straw, their ‘mate’ (pronounce maty), a type of tea made from the leaves and stems of Yerba paraguariensis. It is generally drunk from a special calabash ‘cup’ through a silver straw, which also serves as sift to keep the leaves from your mouth. The calabash is usually passed from one person to another, with each person taking a sip from the brew!  It is even passed around in class!  Another thing in conflict with the upbringing I received from my mother (as is the cup at communion)!,” says Prof Spies.

“My short visit also taught me that the Argentinians are a proud nation that often faced adversity in the past. Nevertheless, they do not try to change their past. Street names even refer to dates from their past when, for example, they were attacked by England (in 1807). Only the almost 30 000 people who disappeared under the military regime, are rarely talked about!,” says Prof Spies.
