A rough December at the Gibraltar Mine offset an above average October and November, according to their year-end sales and production report.
Through the first two months of the fourth quarter, mill throughput at the mine had been averaging close to 88,000 tonnes per day.
But, that production dropped to just 63,000 tonnes per day in December, after a power outage led to an unplanned shutdown.
While the outage lasted just 24 hours, milling operations were shut down for several days after equipment was exposed to the extreme colds.
Crews were able to safely repair the equipment, and return the mill to full capacity by the month’s end.
In total, the mine produced 97 million tonnes of copper in 2022, and sold roughly 101 million tonnes.
