Zimbabwean mining company Kuvimba Mining House has introduced a blockchain-based mine-to-market traceability system for its gold production in the country. This system ensures that all gold from Kuvimba is traceable from the mine to international markets. Kuvimba, the country’s largest gold producer, emphasizes transparency, legitimacy and responsible mining. The Comstack system, which uses blockchain technology, improves traceability and compliance with international standards. The system is operational at the Freda Rebecca and Jenna mines, with plans to expand to other mineral production scales.
