Dr Martin Clark
Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

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.

Reverend Frank Chikane honours ‘Oom Bey’ at second Beyers Naudé Memorial Lecture for 2012

The 9th Beyers Naude Memorial Lecture, a partnership initiative between the University of the Free State (UFS) and Kagiso Trust, was held on the South Campus of the university last week. The theme of the lecture focused on Collaborative partnership for social cohesion: Building of a nation with ethics.

Guest speaker, Reverend Frank Chikane, is a member of the UDF, ANC, Director-General in the Office of the President and a board member of Kagiso Trust.

In his speech, Rev. Chikane focused on the first 45 years in the life of Beyers Naudé, sketching a picture of a man who lived for what he believes in. When this former minister of the South African Dutch Reformed Church and member of the Broederbond, decided to question the morality of the Apartheid government after the Sharpeville Massacre in 1960, he made some changes in his beliefs and started to play a big role in the struggle against apartheid.

“If one know about ‘Oom Bey’s’ earlier life, you will see how radical his contribution was in turning South Africa from a country on the brink of destruction to a country of peace. ‘Oom Bey’ must be seen as a role model, someone we can aspire to be in South Africa today,” Rev. Chikane said.

“From his legacy one sees elements of someone building a nation with ethics.

“He took sides with the poor against an unjust system. Power breaks cohesion. It makes people not to think,” Rev. Chikane said.

If Afrikaners and black people stood together after the South African War (Anglo-Boer War), we would have talked a different language today. However, they did not. Afrikaners stood together, excluding black people and cohesion between all races was destructed. ‘Oom Bey’ tried to build relationships between people from all races in South Africa in an effort to create peace amongst all people. He was alienated from the Broederbond and defrockedrom the church.

In his speech, Rev. Chikane also said that South Africa did not succeed in collaborative partnerships in terms of the economy. “We need collaborative action to change our economy. This specific failure can destroy all that we have built together.”

“All South Africans can be like ‘Oom Bey” and make a contribution, especially in terms of the economy. To deal with this challenge, we can all contribute. This is important because due to a poor economy, many people are desperate and desperate people can destroy any relationship that we might have built so far.”

At this event, the university and Kagiso Trust also announced the winners of a poetry and essay competition that coincided with this last Beyers Naudé lecture for 2012. The award ceremony looked at the creativity of the learners, how they expressed themselves as well as the novelty of their work. Students as well as learners from schools in the Free State participated in the competition and first, second and third place winners received cash prizes as well as a book from Rev. Frank Chikane for their brilliant work.
