Gold miner Barrick Gold says that, since acquiring the former Acacia Mining assets, in Tanzania, in September 2019, it has reestablished North Mara and Bulyanhulu as “world-class” mines, and that it has also rebuilt their social licence to operate. President and CE Mark Bristow told Mining Weekly this week that independent consultants Synergy Global Consultants had concluded, after a second site visit, that Barrick had made considerable progress in mitigating the environmental, social and security risks at North Mara.
