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.

Weideman focuses on misconceptions with regard to survival of Afrikaans

On the survival of a language a persistent and widespread misconception exists that a “language will survive as long as people speak the language”. This argument ignores the higher functions of a language and leaves no room for the personal and historic meaning of a language, said the writer George Weideman.

He delivered the D.F. Malherbe Memorial Lecture organised by the Department Afrikaans at the University of the Free State (UFS). Dr. Weideman is a retired lecturer and now full-time writer. In his lecture on the writer’s role and responsibility with regard to language, he also focused on the language debate at the University of Stellenbosch (US).

He said the “as-long-as-it-is spoken” misconception ignores the characteristics and growth of literature and other cultural phenomena. Constitutional protection is also not a guarantee. It will not stop a language of being reduced to a colloquial language in which the non-standard form will be elevated to the norm. A language only grows when it standard form is enriched by non-standard forms; not when its standard form withers. The growth or deterioration of a language is seen in the growth or decline in its use in higher functions. The less functions a language has, the smaller its chance to survive.

He said Afrikaans speaking people are credulous and have misplaced trust. It shows in their uncritical attitude with regard to the shifts in university policies, university management and teaching practices. Afrikaners have this credulity perhaps because they were spoilt by white supremacy, or because the political liberation process did not free them from a naïve and slavish trust in government.

If we accept that a university is a kind of barometer for the position of a language, then the institutionalised second placing of Afrikaans at most tertiary institutions is not a good sign for the language, he said.

An additional problem is the multiplying effect with, for instance, education students. If there is no need for Afrikaans in schools, there will also be no  need for Afrikaans at universities, and visa versa.

The tolerance factor of Afrikaans speaking people is for some reasons remarkably high with regard to other languages – and more specifically English. With many Afrikaans speaking people in the post-apartheid era it can be ascribed to their guilt about Afrikaans. With some coloured and mostly black Afrikaans speaking people it can be ascribed to the continued rejection of Afrikaans because of its negative connotation with apartheid – even when Afrikaans is the home language of a large segment of the previously oppressed population.

He said no one disputes the fact that universities play a changing role in a transformed society. The principle of “friendliness” towards other languages does not apply the other way round. It is general knowledge that Afrikaans is, besides isiZulu and isiXhosa, the language most spoken by South Africans.

It is typical of an imperialistic approach that the campaigners for a language will be accused of emotional involvement, of sentimentality, of longing for bygone days, of an unwillingness to focus on the future, he said.

He said whoever ignores the emotional aspect of a language, knows nothing about a language. To ignore the emotional connection with a language, leads to another misconception: That the world will be a better place without conflict if the so-called “small languages” disappear because “nationalism” and “language nationalism” often move closely together. This is one of the main reasons why Afrikaans speaking people are still very passive with regard to the Anglicising process: They are not “immune” to the broad influence that promotes English.

It is left to those who use Afrikaans to fight for the language. This must not take place in isolation. Writers and publishers must find more ways to promote Afrikaans.

Some universities took the road to Anglicision: the US and University of Pretoria need to be referred to, while there is still a future for Afrikaans at the Northwest University and the UFS with its parallel-medium policies. Continued debate is necessary.

It is unpreventable that the protest over what is happening to Afrikaans and the broad Afrikaans speaking community must take on a stronger form, he said.
