Pretium Pours First Gold at Brucejack
Pretium Resources announced on June 30 it has poured the first gold at its Brucejack mine in northwest British Columbia and followed up with an announcement on July 7 that the mine has reached commercial production. The gold pour announcement included a report that Brucejack’s flotation and gravity circuits are operational and that gold-silver flotation concentrate is being produced and bagged, with initial shipments scheduled to depart in the near term.
The commercial production date was defined as the first day of the calendar month immediately following the first calendar month during which the Brucejack plant processed ore at an average rate of 60% of monthly nameplate capacity. Annual processing capacity is 985,500 metric tons per year (mt/y) or 2,700 mt per day (mt/d).
September Gold Pour Targeted for Rainy River
New Gold Inc. reported in late June that it is targeting first gold production from its Rainy River project in northwest Ontario in September, with the project expected to reach commercial production in November. Project planning calls for production of 325,000 oz/y of gold at full production. The processing rate will be 21,000 mt/d from a combination of open-pit, underground and stockpiled ore.
Project spending for Rainy River totaled $903 million through March, and spending of an additional $389 million was planned through to the start of commercial production.
