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.

ANC Centenary Dialogue reflects on past leadership
2011-10-12

 

Making their mark at the ANC Centenary Dialogue were, from left to right: Prof. Kwandiwe Kondlo, Senior Professor: Centre for Africa Studies (UFS); Dr Adekeye Adebajo, Director: Centre for Conflict Resolution (Cape Town); and Prof.  E C Ejiogu, Senior Researcher: Centre for Africa Studies (UFS). 

The Centre for Africa Studies at our university recently hosted its ANC Centenary Dialogue at the Bloemfontein Campus. Keynote speaker, Dr Adekeye Adebajo, delivered a paper titled Nelson Mandela, Thabo Mbeki, and the ANC’s Footprint in Africa. The lecture focused on two of South Africa’s democratically-elected presidents.

Mr Nelson Mandela was South Africa’s first democratically-elected president. This Nobel Peace Laureate played a prophetic leadership role in Africa in 1993. He was inspired by Mr Mahatma Gandhi’s tactics of ‘passive resistance’, which played a role in the ANC’s Defiance Campaign.
 
Mr Mandela’s visit to other African countries gave him insights into continental diplomacy and the tactics of other liberation movements. “The ANC used Madiba to embody the face of the struggle. He emerged from prison without any bitterness towards his enemies. He tirelessly promoted national reconciliation,” said Dr Adebajo.
 
Unlike other post-independence ‘Founding Fathers’, Mr Mandela bowed out gracefully at the end of his first presidential term in 1999, setting a standard for future African leaders aspiring to greatness. “Mr Mandela’s lasting legacies are his efforts at promoting national and international peacemaking,” elaborated Dr Adebajo.
 
Mr Thabo Mbeki challenged Africans to discover a sense of their own self-confidence after centuries of slavery and colonialism. Under his foreign policy, South Africa established solid credentials to become Africa’s leading power. He sought multilateral solutions to resolve regional conflicts. Mr Mbeki also sent peacekeepers abroad and increased South Africa’s credibility as a major geostrategic player in Africa.
 
Many question whether Mr Mbeki’s heirs, President Jacob Zuma and beyond, will maintain the same level of commitment to the continent that he demonstrated. Mr Mbeki has bequeathed this foreign policy legacy to his successors. “These very different ANC leaders have left a heavy African footprint on the sands of time,” concluded Dr Adebajo.
