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.

Minister Jeff Radebe commends UFS for measures taken to address racial prejudices

Minister Jeff Radebe lecture: YouTube video

Mr Jeff Radebe, Minister of Justice and Constitutional Development, last night delivered a lecture in the Prestige series of the Dean: Faculty of Law, at the Bloemfontein Campus of the University of the Free State (UFS).

In a packed hall with, among others, university students, staff and members of the judicial system, Minister Radebe said that many other academic institutions should look to the UFS when they deal with the challenges of racism in its various manifestations in their midst. “I commend the university for taking drastic measures to address the challenges of racial prejudices in its own backyard,” he said.

“Government can and must provide leadership, but it is the collective efforts of all our people that will ensure that we bridge the racial and historical divides that stand in contrast to our noble virtues as entailed in the Constitution,” the Minister said.

On the topic “Access to Justice” the Minister said that the Department of Justice and Constitutional Development has channelled more than 80% of its nearly R16 billion budget to the Access to Justice programme.

Minister Radebe talked about the reintroduction of the Sexual Offences Courts, which attests to the unrelenting resolve to eliminate the scourge of gender-based violence. “Fifty-seven of the department’s Regional Courts are being upgraded to operate as dedicated Sexual Offences courts during the 2013/2014 financial year. We believe that these sexual offences courts will help address the growing challenge of sexual offences in the country, particularly against vulnerable groups.”

The Minister also pleaded with law teachers to avail themselves to preside in the courts in our country to complement the decreasing number of presiding officers that are drawn from the attorneys’ and advocates’ profession. These services are normally rendered by the Commissioners pro bono as part of an endeavour to bring justice to all the people, including the poor.

A challenge that the UFS could help resolve,is the transformation of the legal profession. “We need to increase the number of Law students and in turn increase the number of attorneys and advocates in the pool from which we derive candidate judges,” Mr Radebe said.

The Legal Practice Bill and the transformation of the State Legal Service are the most important initiatives underway by which the Institutions of Higher Learning will make a contribution. “The Bill seeks to establish a single regulatory structure, which will be responsible for setting the norms and standards for all legal practitioners. Members of the public, as primary beneficiaries of the legal profession, will also be represented in this structure. Other important objectives of the Bill are the removal of barriers of entry to the profession for young law graduates who aspire to pursue a legal career, and the introduction of measures aimed at ensuring that fees chargeable for legal services are reasonable and within reach of ordinary citizens,” he said.

The Minister concluded: “Our courts must reflect both the race and gender demographics of our country and so must the university communities in their various capacities as a microcosm of the society we seek to build.”
