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 presents sport concussion programme for schools
2008-11-14

The Sports Medicine Clinic at the University of the Free State (UFS) will present a sports concussion programme for schools in the Free State.

“The Pharos Schools Concussion Programme makes the latest methods and technology in concussion management available to learners who play contact sport,” says Dr Louis Holtzhausen, Programme Director of Sports Medicine at the UFS.

The great risk of concussion is that there is an uncertainty about when a player can return to a sport with safety and with the minimum complications in the brain. This programme fills that gap to a large extent.

“By using this programme, no player who suffers concussion will return to play before it is medically safe to do so. The programme also educates players, parents, coaches and the medical fraternity on how to manage sports concussion,” says Dr Holtzhausen.

The programme has been designed for hockey, soccer, cricket, rugby and other contact and collision sports.

SA Rugby has used the programme for professional players for the last five years and advocates that all school rugby players should participate in the programme.

Several sports teams from schools in and around Bloemfontein as well as the University’s Shimla and Irawa rugby teams have already been tested. This will provide invaluable information in the management of possible head injuries.

“We can now give definite guidelines to players and coaches regarding the safe return of players to teams after such an injury. It takes a lot of the guesswork out of the management of concussion and provides peace of mind to coaches, parents and players regarding serious injuries,” says Dr Holtzhausen.

By enrolling in the concussion programme, learners and their parents are ensured of among others:

A baseline computer brain-function test before the start of the season.
Information on how to recognise and treat concussion, including a fieldside information card for the player’s team.
A free consultation and neurological examination by a sports physician after any suspected concussion.
As many brain-function tests and sports-physician consultations as necessary after any concussion, until complete recovery.
Referral to a network of specialists if necessary.

The Pharos Programme uses a cognitive function evaluation called Cogsport. This is a neurophysiological test that measures brain function before the season starts. In this way, a baseline standard is established and, should concussion occur during the season, the extent of it can be measured according to the baseline and rehabilitation.

“Once we have the baseline values, the concussed player’s return to those levels must be monitored. He/she can return to light exercise in the meantime and semi- and full-contact can be introduced at appropriate times,” says Dr Holtzhausen.

The cost of enrolment is R200 per learner, regardless of the number of concussions suffered or sports physician consultations received. “By enrolling in this programme, parents will ensure that their child has the best chance of avoiding the potentially serious consequences of concussion, including learning disabilities, recurrent concussions, epileptic fits and even death,” says Dr Holtzhausen.

More information on the programme can be obtained from Ms Arina Otto at 051 401 2530.
