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.

On Friday 4 December 2015, Penny Siopis, the well-known Cape Town-based artist, who has been exhibiting her work locally and internationally since 1975, was presented with the 2015 Helgaard Steyn Award and a prize of R 550 000 for her painting entitled Swarm.

A quadrennial award lunch was hosted by the University of the Free State (UFS) Johannes Stegman Gallery in conjunction with the Helgaard Steyn and ABSA Trusts. The Helgaard Steyn Trust was established by the estate of Dr Jan Steyn and was named after his father and his brother who was the last president of the Orange Free State Republic.

Swarm, a 2011 painting using ink and glue on canvas, depicts a swarm of bees in a complex, dynamic, and intense manner. It earned the prestigious award that is dedicated to the promotion of artistic culture based on the adjudicators’ unanimous decision. Angela de Jesus, curator of the Johannes Stegmann Art Gallery at the UFS, Annali Dempsey of the University of Johannesburg Gallery, and Prof John Botha, Associate Professor in Art History at North West University, made up the 2015 panel of judges.

On receiving the award, Siopis thanked the Steyn family, the judges, and the people who nominated her. “I am struck by how fantastic it feels to be acknowledged. It is extraordinary when people are struck by what was your own world and the intensity buzzing in your head.”

According to Prof Botha, “Naturally the work of art is chosen on grounds of artistic merit and in the context of contemporary values with regards to both form and content.”

The award-winning painter studied Fine Arts at Rhodes University and Portsmouth University in United Kingdom. Apart from lecturing Fine Arts at the University of the Witwatersrand, she is an honorary professor at University of Cape Town Michaelis School of Fine Art. She has also taught at the Natal Technicon in Durban.

Siopis has received numerous awards for her work, including a British Council Scholarship, a Merit Award at the 2nd Cape Town Triennial, and the Atelier Award for a residency at the Cité Internationale des Arts in Paris, in addition to the Alexander S Onassis fellowship for research in Greece.
