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.

Kovsie wins luxury apartment in Paarl-Franschhoek Valley

The saying “Dreams do come true” is a perfect explanation for 25-year-old Palesa Moisi who was announced winner of the Win A Home competition.

Palesa, who is currently completing a Postgraduate Certificate in Education at the University of the Free State, is the proud owner of a beautiful apartment worth almost R3 million. The day after the announcement, she was escorted to the Val de Vie Estate to pick her dream apartment from three beautiful designer apartments.

Proud owner of apartment at Val de Vie

With Win A Home Season 3 on SABC 3’s Afternoon Express, viewers not only stood a chance to win bi-weekly prizes, but Palesa walked away with a two-bedroomed furnished apartment in the Polo Village at the prestigious Val de Vie Estate in the Paarl-Franschhoek Valley near Cape Town. The draw took place on 26 August 2016 at the Afternoon Express Studios.

Time stood still for a moment

Palesa says when she stepped towards the safe, which each contestant was assigned to, and opened it, everything just stood still. A key to the apartment was inside one of the safes. “My mind was somewhere else and when I saw the key I realised: ‘Hey I need to take it out and show it to everyone’.”

Financial constraints are a big issue for her family. Her mother is a single parent and Palesa has a younger sister who needs to be cared for. “I’m still a student and I think that if I rent out the house for now, I will be able to pay for my fees and take some pressure off of my mother,” she says.
