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.

Project aims to boost science pass rate

The University of the Free State (UFS), in partnership with computer giant Hewlett Packard (HP), wants to boost the pass rate of its science students by using mobile technology.

The UFS is one of only 15 universities across Europe, the Middle East and Africa and the only university in South Africa to receive a grant from HP to promote mobile technology for teaching in higher education valued at USD$ 100,000 (or about R1 million). Altogether 80 universities from 28 countries applied for the grant.

“Last year HP invited a number of selected universities to submit proposals in which they had to explain how they are going to utilise mobile technologies in the redesign of a course that is presented at the university. The proposal of the Centre for Education Development (CED) at the UFS entitled “Understanding Physics through data logging” was accepted,” says Mr Cobus van Breda, researcher at CED and manager of the project.

According to Mr van Breda, students who do not meet the entrance requirements for the three-year B.Sc. programme have to enroll for the four-year curriculum with the first year actually preparing them for the three-year curriculum.

In order to increase the success rate of these students, the project envisages to enhance their understanding of science principles by utilising the advantages of personal computer (PC) tablet technology and other information and communication technologies (ICT) to support effective teaching and learning methodology.

“By using PC tablet technology in collaboration with data-logging software, a personal response system, the internet and other interactive ICT applications, an environment different from a traditional teaching milieu is created. This will consequently result in a different approach to addressing students’ learning issues,” says Mr van Breda.

The pilot project was launched during the fourth term of 2008 when 130 first-year B.Sc. students (of the four-year curriculum) did the practical component of the physics section of the Concepts in General Science (CGS) module by conducting experiments in a computerised laboratory, using data-logging software amongst other technology applications. “The pilot project delivered good results and students found the interactive application very helpful,” says Mr van Breda.

”The unique feature of the latter is the fact that real-life data can be collected with electronic sensors and instantly presented as computer graphs. It can then be analysed and interpreted immediately, thus more time can be devoted to actual Science principles and phenomena and less time on time-consuming data processing,” says Mr van Breda.

The CGS module can be seen as a prerequisite for further studies in physics at university level and in this regard it is of essence to keep looking for new models of learning and teaching which can result in student success. This year the theoretical and practical component of the physics section of the CGS programme will be done in an integrated manner.
