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.

The silent struggles of those with invisible disabilities

December is International Disability Awareness Month. Despite equality before the law and some improvements in societal attitudes, people with disabilities are still disadvantaged in many aspects of their lives. They are more likely to be the victims of crime, sexual abuse, are more likely to earn a low income or be unemployed, and less likely to gain qualifications than people without disabilities.

Demystifying disabilities is crucial

Dr Magteld Smith, a researcher at the University of the Free State (UFS) School of Medicine’s Department of Otorhinolaryngology, says that often people think the term “disability” only refers to people using a wheelchair, etc. However, this is a misperception because some individuals have visible disabilities, which can be seen, and some have invisible disabilities, which can’t be seen. Others have both visible and invisible disabilities. There is an ongoing debate as to which group has the greatest life struggles. Those with visible disabilities frequently have to explain what they can do, while individuals with invisible disabilities have to make clear what they cannot do.

Invisible disability is an umbrella term that captures a whole spectrum of invisible disabilities and the focus is not to maintain a list of specific conditions and diagnoses that are considered invisible disabilities. Invisible disabilities include debilitating fatigue, pain, cognitive dysfunctions, mental disorders, hearing and eyesight disabilities and conditions that are primarily neurological in nature.

Judging books by their covers
According to Dr Smith, research indicates that people living with invisible disabilities often suffer more strained relationships than those with visible disabilities due to a serious lack of knowledge, doubts and suspicion around their disability status.

Society might also make serious allegations that people with invisible disabilities are “faking it” or believe they are “lazy”, and sometimes think they are using their invisible disability as an “excuse” to receive “special treatment”, while the person has special needs to function.

Giving recognition and praise
“One of the most heartbreaking attitudes towards persons with invisible disabilities is that they very seldom enjoy acknowledgement for their efforts and accomplishments. The media also seldom report on the achievements of persons with invisible disabilities,” says Dr Smith.

Society has to understand that a person with a disability or disabilities is diagnosed by a medical professional involving various medical procedures and tests. It is not for a society to make any diagnosis of another person.

Dr Smith says the best place to start addressing misperceptions is for society to broaden its understanding of the vast, varying world of disabilities and be more sensitive about people with invisible disabilities. They should be acknowledged and given the same recognition as people with visible disabilities.
