VANCOUVER, British Columbia, Sept. 15, 2025 (GLOBE NEWSWIRE) -- B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) (“B2Gold” or the “Company”) is announcing an update on operational performance year-to-date in 2025 at each of its four mines. B2Gold confirms 2025 total annual gold production of between 970,000 and 1,075,000 ounces.
Goose Mine - Canada
The Goose Mine achieved first gold pour on June 30, 2025
The mine remains on track for commercial production in the coming weeks, and estimates strong gold production in Q4 2025
Project commissioning activities are nearing completion at the Goose Mine. Since first gold production in late June 2025, the Goose mill is achieving consistent performance and daily throughput is increasing. Current daily throughput is approximately 75% of the 4,000 tonnes per day (“tpd”) design capacity (above the Company’s targeted average commercial production rate of 65% of the design capacity) and will increase to full design capacity in the near term as described below.
B2Gold anticipates achieving commercial production at the Goose Mine in the coming weeks. The Goose Mine is currently operating, and plans to achieve commercial production, with the use of supplemental mobile crushing capacity to ensure a consistent feed of crushed ore to the mill, as crushing plant capacity has been limited during the third quarter of 2025. B2Gold believes that with this supplemental mobile crushing capacity the Goose mill can operate at design capacity of 4,000 tpd following the throughput ramp-up. Permanent optimizations to the primary crushing and secondary grinding circuits and the installation of surge bin capacity have been engineered, designed, and are being implemented. Use of the mobile crusher is expected to allow the mill to run at design throughput while these modifications are implemented.
Due to the crushing plant capacity shortfall in the third quarter of 2025, B2Gold is modifying its 2025 gold production guidance for the Goose Mine to 80,000 to 110,000 ounces (original guidance range of 120,000 to 150,000 ounces). B2Gold anticipates gold production in the fourth quarter of 2025 to be in line with original estimates of approximately 70,000 ounces. The Company reiterates the near-term and long-term gold production estimates at the Goose Mine, which included gold production forecasts of approximately 250,000 ounces of gold production in 2026, approximately 330,000 ounces of gold production in 2027, and average annual gold production for the initial full six years of operations (2026 to 2031 inclusive) of approximately 300,000 ounces per year, based only on existing Mineral Reserves.
In addition, work continues on the multiple optimization studies for the Goose Mine as previously announced in March 2025, including the evaluation of a flotation / concentrate leach process and the potential installation of a SAG mill to be paired in conjunction with the existing 4,000 tpd ball mill, which could expand mill throughput capacity up to 6,000 tpd. The results of these studies are expected to be finalized in late 2025, and will also reflect two additional value drivers for the Goose Mine related to the potential reduction in carbon taxes paid over the life of the mine, and a reduction in the annual amount of fuel consumed as a result of equipment optimizations.
