Pretium Resources Inc. produced 96,342 ounces of gold in the fourth quarter from its Brucejack mine in British Columbia, up 37.1% from 70,281 ounces of gold in 2017.
The mine produced 188,983 ounces of gold in the second half, just short of the company's second-half guidance of 200,000 ounces of gold.
Full-year output, meanwhile, stood at 376,012 ounces of gold, which was also below 2018 guidance of 387,000 ounces of gold.
Pretium said Jan. 9 that it will continue refining the grade control program in the next quarters to improve short-term grade estimation and predictability, after the program overcalled actual mill production during the quarter.
With the program implemented, head grade averaged 12.9 g/t of gold for the second to fourth quarters.
Pretium added that a specific timeline for the ramp-up to a production rate of 3,800 tonnes per day, along with production and cost guidance for the year, is expected later in the first quarter.
