UFS researcher makes MAGIC for the mining industry

29 July 2019 | Story Leonie Bolleurs

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.

UFS doctors fight childhood cancer

Of 23 paediatric oncology specialists nationally, Prof David Stones and Dr Jan du Plessis of the University of Free State are the only ones in the province.

Committed to giving holistic care to their patients, the two doctors specialise in all types of childhood cancers, the most common being leukaemia, brain tumour, and nephroblastoma.

They describe the childhood malignancy as a lethal disease, unpredictability being its harshest trait. “With cancer, you can just never know. It precipitates and multiplies, and leads to the failure of other organs. You can just always hope, and keep trying,” said Du Plessis.

The paediatric oncology unit of the Universitas Academic Hospital, their unit, is the liveliest floor in the entire building. It is also the third busiest in South Africa, serving a demographic that spans the Free State and Northern Cape, as well as parts of North West, Eastern Cape and Lesotho.

Each year, the unit receives more than 100 new childhood cancer patients. In 2015, the unit had 113 newly diagnosed patients, an increase from 93 in 2014.

Lack of knowledge poses a serious challenge
According to the two experts, the lack of insight and awareness of the disease remain a big challenge to fighting it. “It is frustrating. Parents and family members don’t know anything about it. Nurses and doctors aren’t always clinically trained to pick up the early warning signs. By the time a diagnosis is made, life and death is on a 50% margin,” Stones said.

Poverty, a lack of resources, overcrowding and a range of health issues are other factors that have a profound effect on the diagnosis and treatment of the disease.

Making a contribution that will last
With a desire to see an improvement on life outcomes in the health sector, the team is focusing on educating the country’s doctors of tomorrow. Their unit is the only one in the country that actively involves medical students in an oncology unit, giving them practical experience and exposure to the individual cases each patient presents. They have also produced a substantial amount of research literature on childhood malignancies in South Africa as a developing country.

Driven by passion to see a better South Africa
The doctors are passionate about the work they do, and remain hopeful there will be a change in the incidence of childhood cancer not just in decreased levels of the disease, but also in the overall state of well-being of young South Africans.
