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.

Read a book SA encourages South Africans to read one book a month

'Read a book SA's" objective is to bring reading into the everyday lives of South Africans. Speaking at Writers’ Day on the Qwaqwa Campus of the University of the Free State last Thursday, Ditshego said reading was essential. “Of all the skills that anyone can ever have, reading is the most fundamental of them all. It improves one's attention, confidence and discipline, amongst others.”

Ditshego asked why South Africa is presently faced with a 25,2% unemployment rate compared to Germany's 6-8%, despite South Africa having more and better natural resources. The answer, according to him, rests with lack of knowledge and critical skills in South Africans.

“Out of 144 countries, South Africa is ranked 133th in as far as the delivery of quality education is concerned. The reason for this is that South Africans lack knowledge, as they do not read enough. Most South Africans read for information, which is different from knowledge,” Ditshego argued.

In his welcoming remarks, Campus Principal Dr Elias Malete challenged authors to continue reminding society of their responsibilities.

“It is also your duty and responsibility to teach diplomacy lessons, to teach about effective leadership that is accountable, fair and transparent,” said Dr Malete.

Amongst the established authors who shared their wisdom with budding writers was Dr KPD Maphalla, a Sesotho literature guru and custodian of Sesotho language and culture. UFS students and learners from Sekgutlong and Tiisetsang secondary schools had the opportunity to showcase their writing skills. They also received expert advice on manuscript development and publishing from Mathene Mahanke from the Free State's Department of Sport, Arts, Culture and Recreation.

The annual Writers' Day is a joint venture of the Campus Principal and the Library and Information Services (LIS).
