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.

New security measures for Rag fundraising
2012-01-25

The University of the Free State will no longer allow first-year students to sell Ritsems or to shake their cans for change at traffic robots in Bloemfontein in an effort to raise funds for Rag Community Service.

This decision follows after an evaluation has been done in 2011 and 2012 concerning the safety risk for students during this type of sales at road crossings.
 
The new security measures have specifically been implemented for this type of sales since last year.
 
The measures included, among others, that students should be obliged to wear brightly coloured safety jackets during sales, continuous supervision of first-year students by senior students to ensure that students keep to the rules of the road, and limiting the sales hours at robots.
 
Through notices in the media, an appeal was made on motorists to keep a lookout for students raising money for Rag Community Service. The measures were implemented and the effects thereof for students’ safety during sales at robots monitored since last year. This follows after a student, Ms Hanje Pistorius, was hit by a reckless driver in 2010 and she subsequently lost her leg as a result of the accident. 
 
Although, from all appearances, the new measures are a positive contribution to protect students even more, the UFS decided to abolish the sales and fund-raising actions at traffic robots. As reckless drivers would not necessarily take notice of the extra measures, the risk to students at robots stay unchanged. 
 
"The UFS sets the safety of its students as first priority and considers it in the best interest of students to not expose first-years to the risk during our Rag programme,” says Mr Rudi Buys, Dean: Student Affairs at the UFS.
 
Night fund-raising and the selling of Ritsem in the city’s suburbs will, however, continue. 
 
Although the UFS do not expect the new measures to be detrimental to fund-raising efforts, Rag Community Service currently considers new supporting proposals for the raising of funds for community projects in order to address any possible reduction in funds. 
 
Mr Buys also has an agreement with Ms Pistorius to assist Rag Community Services in the planning of new projects.
 
The Night fund-raising in suburbs will take place on Tuesday 24 January and Thursday 26 January and the UFS calls on residents to assist students and help them in the important task at hand.
 
Three Rag processions will take place on Saturday 28 January 2012. At 10:00 two Rag procession will be leave for Heidedal and Mangaung, where the Kovsie Rag Community Service will hand out food parcels.
 
The main Rag Procession will leave the UFS at 18:00 and will move towards the Old Greys sports ground for the Rag concert with Die Heuwels Fantasties and DJ Black Coffee.
