Geospatial Information for E-Gov in Africa: Unlocking Africa’s Geospatial Potential for Mining

Challenge description

In order to highlight the diverse applications of geospatial technology and showcase its potential to foster sustainable and responsible mining practices across Africa, it is essential to delve into the multifaceted aspects of leveraging geospatial technology, exploring its role in environmental monitoring, operational optimization, community engagement, regulatory compliance, and data analytics. 

Geographic Information Systems (GIS) and remote sensing technologies enable real-time monitoring and assessment of environmental impacts associated with mining activities. These tools facilitate the implementation of mitigation measures to minimize ecological damage. Among the key features of digital applications and automation systems is their ability to enhance operational efficiency and safety by enabling remote monitoring, control of equipment, and optimization of mining processes. What is more, digital platforms and participatory GIS tools foster transparent communication with local communities, empowering them to participate in decision-making processes and address social concerns related to mining activities.

Regarding regulatory compliance, digital permit management systems streamline regulatory processes, ensuring adherence to environmental regulations, and permit conditions, thereby reducing risks of non-compliance and associated penalties. As for data analytics, the advancements in the sphere provide valuable insights into spatial relationships, trends, and patterns, informing strategic decision-making processes and optimizing resource extraction.

Solutions

A number of African countries have already started the implementation of geospatial technology as a means of ameliorating the process of mineral extraction. 

  • The Tanzanian government, in collaboration with international organizations and NGOs, is employing geospatial technology to monitor Artisanal and Small-Scale Mining (ASM) sites. GIS and remote sensing technologies are used for real-time monitoring of ASM activities, environmental management, and addressing illegal mining activities.
  • Mining companies in Ghana utilize geospatial technology extensively in Environmental Impact Assessment (EIA) for large-scale mining operations to assess potential environmental impacts on ecosystems, water resources, and local communities. GIS and remote sensing techniques aid in mapping mining concessions, monitoring land use changes, and assessing habitat fragmentation.
  • In South Africa, geospatial technology is utilized for mine rehabilitation and closure planning in the Witwatersrand Goldfields. Mining companies operating in the region use geospatial information to assess the environmental legacy of historical mining activities, plan rehabilitation measures, and restore degraded landscapes. GIS helps identify priority areas for rehabilitation, determine land use options post-mining, and estimate remediation costs.
  • The government of the Democratic Republic of the Congo, in collaboration with international organizations, employs geospatial technology to track and certify the origin of conflict minerals. GIS, satellite imagery, and GPS tracking technologies are used to map mining concessions, monitor mineral extraction activities, and ensure transparency in the supply chain. For instance, Kamoya Mining Corporation (KMC) has implemented a comprehensive GIS to enhance its copper and cobalt mining operations in Katanga Province. Geospatial technology supported site selection, environmental monitoring, community engagement, operational efficiency, and safety, thereby improving sustainability and stakeholder engagement.

Case Study: Geoscan’s Geospatial Exploration for Salma International Sarl in Burkina Faso

In June 2023, Geoscan’s team of geophysicists undertook a comprehensive aerial photography and magnetic exploration project in Burkina Faso on behalf of Salma International Sarl, a prominent gold mining company. This project covered extensive territories in both the northern and southern regions of Burkina Faso, spanning a total linear distance of 2,956 kilometers.

Burkina Faso stands as one of the leading gold-producing countries in Africa, with Salma International Sarl emerging as a key industry player with a strong focus on technological innovation. Following their initial interaction at the PDAC 2020 conference, Salma International Sarl sought Geoscan’s expertise for aerial photography and magnetic reconnaissance services to enhance their exploration activities.

To facilitate this project, Geoscan procured two Unmanned Aerial Vehicles (UAVs) and the GeoShark magnetometer. Additionally, comprehensive training sessions were organized for Salma International Sarl’s engineers, focusing on the assembly of the equipment and hands-on training for data processing using Agisoft Metashape Pro software.

Operating in Burkina Faso’s challenging environmental conditions presented significant obstacles, with temperatures soaring to a blistering +45°C. Despite these extreme heat conditions, Geoscan’s specialists adjusted their working hours from 6 AM to sunset to optimize operational efficiency and ensure safety. The robustness and reliability of the equipment were tested under these extreme conditions, and it performed exceptionally well, ensuring uninterrupted operations throughout the project duration.

Outcomes of the project

The successful completion of this project highlighted the advantages of utilizing modern UAV technologies for mineral exploration, particularly in extreme weather conditions. The project showcased the superior performance, accuracy, and efficiency of UAV-based exploration methods compared to conventional approaches.

Geoscan’s collaboration with Salma International Sarl in Burkina Faso exemplifies the potential of integrating advanced geospatial technologies into mineral exploration activities. Through this partnership, Geoscan demonstrated its capability to deliver high-quality, reliable, and efficient geospatial solutions tailored to the unique challenges of the mining industry, ultimately contributing to the advancement of sustainable and responsible mining practices in Burkina Faso.
