Nord Gold U.K. announced recently it has installed a state-of-the-art monitoring system at its Lefa mine in Guinea. Developed by Swift Geospatial Solutions, a service provider experienced in change detection algorithms, Lefa’s system uses satellite imagery processing algorithms to keep track of the condition of the mine’s tailings storage facilities to proactively identify potential risks. All output is delivered via a custom web application and dashboard.

It also allows the company to monitor community welfare by tracking community dynamics, including house building. Additionally, the technology can help to monitor artisanal mining activities around Lefa’s current mining permit, allowing local management to better assess and prevent potential safety and security hazards. The Lefa mine’s license area spans more than 1,100 km2.
