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.

Maestros from the world stage now lecture at the Odeion School of Music
2014-02-19

 
Prof Ruth Goveia

 
Danré Strydom

 
George Foster

The Odeion School of Music (OSM) at the University of the Free State (UFS) recently endorsed its commitment to excellence with the appointment of three exceptional performing artists and lecturers.

Prof Ruth Goveia (piano), Danré Strydom (clarinet and saxophone) and George Foster (brass instruments) all hold international qualifications. In addition, all of them have received tutelage from world-renowned mentors and performed across the globe. Their respective CVs are awe-inspiring – to say the least.

Prof Goveia has been appointed as an associate professor at our university. She obtained her doctorate in Music in Piano from the Jacobs School of Music at the Indiana University, USA, after completing her master’s degree at the University of Cincinnati. Prof Goveia has gained immeasurable experience while holding positions at several prestigious institutions, including the Albion College in Michigan and the Indiana University.

As a soloist, Prof Goveia’s performances are staggering. She has appeared in a number of recitals across America and even performed as a guest artist at the Kalamazoo College of Music. She took part in the Chamber Music Project of the New York-based Artur Balsam Foundation, and collaborated with clarinetist Randall Paul on a duo tour of Georgia and Alabama.

Danré Strydom has been appointed as a junior lecturer in clarinet and saxophone. She will also co-ordinate the woodwind programme at the OSM. Her training began in Windhoek, Namibia, and continued on to the prestigious Jacobs School of Music in Indiana, USA. From there she joined the Ghent Conservatoire in Belgium, reading for two master’s degrees – completing both cum laude. Strydom has performed with several renowned orchestras ranging from the Vlaams Brabant Symphony (Belgium) to the Sinfonietta Breda (Netherlands).

George Foster is filling the position of a junior lecturer in brass instruments. He completed his BMus degree at the South African College of Music at the University of Cape Town where he received the Anton Rupert Merit prize. As former Fulbright scholar, Foster read for a master’s degree in Music at the University of North Texas. During his study period in the USA he was a member of the University of North Texas Wind Band, the Symphony Orchestra and the Chamber Orchestra. Here, he gained invaluable experience as a conductor as well.

Strydom and Foster are performing their duties at the Free State Symphony Orchestra (FSSO), as well as the OSM. They will both play an integral role as musicians and collaborators within the activities and initiatives of the FSSO, and serve as coaches and instructors for the Free State Youth Orchestra.
