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.

First Dementia Care Mapper in Africa receives international award

“In one facility, four elders who needed minimal assistance to eat were provided with an opportunity to sit at a separate table, and enjoy their breakfast as preferred – that is, to spread bread with butter, jam or marmite; to add their own milk and sugar to their tea.”

Dr Sanet du Toit
described a scenario where staff members at an old-age home implemented recommendations she made following an observation she conducted.

“We do not think twice about doing this but, within institutional care settings, these ’normal’ routines are often replaced with practices that could be viewed as ‘time savers’. For example: everyone gets milky, sweet tea to drink,” she explains.

Yet, by creating an environment where the elderly living with dementia were at liberty to determine the amount of milk in their tea, active participation meant an improved well-being.

She was honoured with the International Association of Homes and Services for the Aging (IAHSA) Award for Excellence in Applied Research on 1 September 2015, at a joint conference held by the Aged & Community Services Australia (ACSA) and IAHSA in Perth.

This exceptional Occupational Therapist from the University of the Free State (UFS) emerged as the first Dementia Mapper from Africa. Dementia Care Mapping is a method used internationally to assess with the purpose of improving the quality of care given to residents in institutionalised settings.

The IAHSA award acknowledged her person-centered care training and research in South African residential care facilities while working at the UFS as a senior lecturer from 2003 to 2013. Currently, she is based at the University of Sydney, but remains an affiliated lecturer at the UFS Department of Occupational Therapy.

In 1992, she graduated with a BA in Occupational Therapy at the UFS, and went on to further her studies at various institutions. Also, she is one of the founding directors of the Eden Alternative South Africa, an advocacy for older persons’ rights within old-age homes. Over the years, Dr du Toit has won numerous awards for her research.
