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.

Housing strategy must accommodate special needs
2005-10-17

Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) 

South Africa’s housing strategy must give attention to people with special needs, including people with disabilities as well as people living with HIV / AIDS and those in poverty.

This was the view expressed by Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) during his recent presentation to the Housing Research Day organised by the Centre for Development Support (CDS) at the University of the Free State (UFS).

Dr Napier previously worked in the national Department of Housing and was involved in shaping the recently launched “Breaking New Ground” housing strategy of Minister Lindiwe Sisulu. 

He said the changing social and demographic trends in South African society, especially after 11 years of democracy, required more flexibility in housing delivery to address the housing needs of different groups of people.  “For example, there are people who wish to or may be required to be spatially mobile because of their work or other reasons. There are also those communities who are vulnerable to disasters,” he said.

According to Dr Napier, housing delivery faced a number of challenges which needed to be addressed, including:

  • the withdrawal of larger construction firms
  • perceptions of low profit margins in the private sector
  • the slow process of developing an emerging contractor sector
  • access to bridging and other finance
  • the ability to retain capacity and expertise mainly at municipal level
  • the acquisition of well located (especially inner city) land

Dr Napier said the new housing strategy – which is called “Breaking New Ground” – tries to go beyond the provision of basic shelter to the establishment of sustainable settlements. It is also tries to be more responsive to housing demand rather than being supply led.

 The new strategy also allows for greater devolution of power to municipalities in the provision of housing, through accreditation to manage subsidies, Dr Napier said. 

He said a survey of people who had benefited from government’s housing programme had shown mixed results, with beneficiaries reporting a sense of security, independence and pride.  Although the location of the houses was poor and there were increased costs, most beneficiaries said they were better off than before, according to the survey.  Beneficiaries also highlighted the problem that they had very little personal choice between houses, sites or settlements.

There was also the perceived failure of developers and municipalities to repair defective houses or adequately maintain settlements, the survey found.
Many beneficiaries also reported that they felt unsafe in their settlements as well as in their own houses.

Prof Lucius Botes, the director of the Centre for Development Support, said the research day highlighted the Centre’s ability to interact with real problems faced by communities, by government, the private sector and civil society.  “This is how we can ensure that the UFS is engaged through our research with our people’s problems and challenges and enables the UFS as a place of scholarship to assist in finding solutions,” Prof Botes said.
