TSX-listed Dundee Precious Metals expects its 2016 concentrate throughput to be about 20 000 t less than planned, after a power outage led to damage to the refractory lining of the Ausmelt furnace at its Tsumeb smelter in Namibia. Subsequent to a power blackout in Namibia on July 22, cooling water entered the Ausmelt furnace as a result of the back-up systems for power and cooling water not operating as expected, which compromised the integrity of the refractory lining.
