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.

Universities join hands in developing literacy tests

The development of academic literacy tests recently took a step into the future with the formal establishment of the Inter-institutional Centre for Language Development and Assessment (ICELDA).

ICELDA, under its first executive head, Prof. Albert Weideman, Head of the Department of English at the University of the Free State (UFS), is a cooperative venture between the multilingual Universities of Pretoria, North-West, Stellenbosch and the Free State.

It is dedicated to the development of reliable state-of-the-art academic literacy tests and currently makes 32 000 tests available to partnering universities annually.

Most notably, it has produced three of the most reliable academic literacy tests in the country. These include an Academic Listening Test and the Test of Academic Literacy Levels (TALL) for undergraduate students, with reliability levels that are more than 20% above international benchmarks.

“We are even more excited about our Test of Academic Literacy for Postgraduate Students (TALPS), which is already a crucial instrument in determining the literacy levels of postgraduate students at the Universities of the Free State, Pretoria and North-West,” said Prof. Weideman.

In addition, ICELDA is currently piloting studies for language tests for financial advisors, nurses, students of disaster management, as well as police studies at Unisa.

ICELDA will also collaborate with the Centre for English Language Communication (CELC) at the National University of Singapore.

“One of the undertakings I made on my visit to Singapore a year ago was that I would assist in every way I could with the building of joint expertise with CELC in language testing,” said Prof. Weideman.

“However, our focus will remain firmly on research.”

He said his goal was to employ the surpluses generated by selling tests to provide promising students with bursaries to stimulate further study and design of academic literacy and other language tests.

By drawing more researchers into the field, Weideman said, ICELDA could provide the capacity for developing reliable language tests that South Africa had always lacked.
