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.

A position statement by the School of Medicine, UFS, regarding the crisis in health care in the Free State
2009-05-27

The executive management of the School of Medicine (SOM) at the University of the Free State (UFS) and its senior members wish to express their grave concern at the way the financial crisis in the Free State has negatively impacted on the provision of health care to the population. The unavailability of goods and services at every level of care has become so severely compromised that the staff of the SOM can no longer remain silent on this issue. By remaining silent it may be construed that we are either indifferent to, or even accepting the situation. Neither is true. The SOM can in no way condone, sanction or accept the current situation of health care in the Free State.

Other concerns expressed by the SOM include:

  • Medical services have been severely compromised due to the disintegrating primary health care system in the FS. This has resulted in patients who were in need of more advanced levels of medical care not being referred appropriately or timeously to level two hospitals and from there for tertiary care. Inpatient as well as outpatient numbers are steadily declining and the tendency now is to fill fewer beds with critically ill or terminally ill patients. It is also becoming increasingly difficult to find suitable patients for training and examination purposes.
     
  • It becomes more difficult to attract and retain experienced and suitably qualified medical specialists interested in an academic career, due to the inability to provide prospective career opportunities. This is particularly the case in the surgical disciplines.
     
  • It is also becoming more difficult to attract and appoint highly qualified registrars (future specialists) since the reputation of this SOM has been compromised by the negative publicity created by the financial difficulties of the FSDoH. Registrars form the backbone of the clinical work force in all teaching hospitals. If vacant posts cannot be filled in time service provision, as well as undergraduate teaching are severely jeopardised.
     
  • As a direct consequence of the rationing of health care, fewer surgical procedures are being performed. The point may soon be reached where registrars in the surgical disciplines may not get sufficient hands-on experience to allow them to qualify within the required time frame.
     
  • Non-payment of accounts to service providers and suppliers including the National Health Laboratory Services (NHLS), maintenance contracts and industry will severely compromises health care and future loyalty, goodwill and provision of critical services.
     
  • The dwindling number of qualified and experienced nurses in the public (and private) health care sector is an ongoing unresolved issue. Despite the fact that primary health care is mainly nurse-driven, nursing colleges were closed during the previous decade. These colleges must now be re-commissioned at high cost adding to the financial burden.
     
  • The morale of health care workers at all levels of health care has reached an all-time low
     
  • It is becoming increasingly difficult to conduct meaningful research in all disciplines due to staff shortages and lack of funding.
