B2Gold said the Goose Mine, part of the Back River Gold District, located in Nunavut, Canada, has achieved commercial production.
“It is with great pleasure that we announce the Goose Mine has achieved commercial production. This tremendous achievement comes just over three months after the commencement of mill operations. I would like to thank our construction and operations teams, whose tireless efforts have made this entire project possible, and acknowledge our partner, the Kitikmeot Inuit Association, for their longstanding support,” said Clive Johnson, president and CEO of B2Gold.
“The Goose Mine will be a cornerstone of B2Gold’s production base and demonstrates the strength of our construction and operating teams worldwide. We view this milestone as just the beginning for the Back River Gold District and look forward to many years of safe and successful production in Nunavut, Canada,” added Johnson.
B2Gold has declared commercial production at the Goose Mine based on an internal commercial production measure of 30 consecutive days of average mill throughput at 65 percent or greater based on the mill design capacity of 4,000 tonnes per day (tpd). From September 3, 2025 through October 2, 2025, the mill achieved an average throughput of 2,652 tpd, which represents 66 percent of design capacity. Mill feed over the 30-day commercial production period has been predominantly from the mined out Echo open pit.
Open pit and underground mining rates at the Umwelt deposit have continued to meet or exceed expectations during the 30-day commercial production period. Gold recoveries have been in line with expectations through the 30-day commercial production period, and are expected to average higher than 90 percent through the fourth quarter of 2025 and beyond.
B2Gold is a responsible international senior gold producer headquartered in Vancouver, Canada. Founded in 2007, B2Gold has operating gold mines in Canada, Mali, Namibia, and the Philippines, and numerous development and exploration projects in various countries.
