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.

Community Engagement Indaba a platform to engage Free State community stakeholders

Description: Community Engagement Indaba  Tags: Community Engagement Indaba  

Gender empowerment meets an all-women’s team
of UFS and UCT law students wanting to learn from the
South African judicial system and be ready to fight the
crimes of rape and domestic violence. From the left are:

The University of the Free State (UFS), through the office of Community Engagements, and in collaboration with Bloemshelter has hosted the Community Engagemen Indaba in Bloemfontein since 2013. This is a platform where stakeholders in business, welfare and other community organisations can network and hold dialogues that can bring about solutions to some of the societal challenges faced by Free State communities.

Bloemshelter is an independent and registered Non-Profit Organisation (NPO) and Public Benefit Organisation (PBO) that provides shelter for the homeless – catering for women, women with children, the elderly, men and frail persons. The shelter accommodates up to 100 people in both the male and female shelters. The growing partnership it has with the UFS over recent years has grown its ability to reach out to local communities in a more effective way.

At the 2016 Community Engagement Indaba, a number of stakeholders were invited to participate in the skills development action-learning workshops, under the theme: Unlocking Human Potential and Creating Jobs.  This was a platform to strengthen the university’s partnerships with NPOs and other advocacy groups in the province. UFS academics, Community Service Learning (CSL) students and community partners gave their presentations while the Director of Community Engagement, Bishop Billyboy Ramahlele, offered carpentry training.

Those who attended received certificates that will in future help them build a portfolio of learning evidence. The conference was about creating meaning, igniting learning, propelling movement, inspiring hope and encouraging sharing by bringing together students, academics and members of communities.  The next Community Engagement Indaba will be held next year, on a date that will be announced early in the year.
