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.

Trade unionist brings today’s policy issues to the table

Sidney Kgara was appointed to the University of the Free State (UFS) Council in January 2015. He was appointed to the Council by Blade Nzimande, the Minister of Higher Education and Training, in one of three such positions.

Sidney heads the public sector union Nehawu's Policy Unit. The National Health Education and Allied Workers Union is the biggest public-sector union and the biggest union in the public service coordinating bargaining council. It therefore stands to reason that researching and drafting policy on issues such as labour market matters, public health and developments in higher education form the core responsibilities of the unit.

No stranger to university governance and leadership

Nehawu has a number of members working at the UFS and before his appointment, Kgara's only contact with the university was through its UFS members. However, he is no stranger to university governance and leadership. He was a student leader at the University of KwaZulu-Natal in the 1990s and as a result has a broad understanding of student governance and university issues.

"Even though it was a different time and the circumstances were different, there is some sense of continuity to the issues we had to deal with then, and the issues that the university faces now," he says.

Kgara’s unique and valuable contributions to the Council

This, together with his experience in policy and research, enables Kgara to make a unique and valuable contribution to the Council.

Kgara is an avid reader and stimulating his mind through reading makes him truly happy. He also loves watching sport and enjoys socialising with friends.
