B2gold Provides Operations Update For The Goose Mine And Announces Drill Results At The Back River Gold District

2026 Regional Exploration Program

The George Project, situated 60 kilometers (“km”) northwest of the Goose Mine (Figure 5), has an Indicated Mineral Resource estimate of 1.66 million tonnes grading 7.89 g/t gold for a total of 420,000 ounces of gold and an Inferred Mineral Resource estimate of 4.19 million tonnes grading 8.98 g/t gold for a total of 1.2 million ounces of gold, including Locale 1 Inferred Mineral Resource estimate of 1.15 million tonnes grading 10.25 g/t gold for a total of 380,000 ounces of gold.

Figure 5. Back River Gold District Property Overview.

Infill drill results from the 2026 George Project and drilling at Locale 1 confirmed the continuity of high-grade gold mineralization in the Inferred Mineral Resource (Figure 6). In addition, approximately 2,279 m was drilled in 15 holes at the George Project, Dragon South, Oar, Rainbow Row, and Spoon targets, focusing on identifying new zones of shallow mineralization that could be amenable to open pit methods. At the Dragon South zone, 1,134 m over 6 holes followed up encouraging 2025 drill results of 10.42 g/t gold over 5.65 m from 10.75 m in drill hole 25GRL224. Assays from the 2026 program are pending.

Significant 2026 drill results from the Locale 1 zone in the George Project include:

Notes:

At the Back River Gold District Regional targets, Boot and Needle, 2,142 m of drilling from 12 holes was completed following up on prospective 2025 exploration program results. At the Boot property, situated 12 km northeast of Goose Mine, 1,693 m was drilled across nine drill holes at the Ayers, Boot Laces, Hammer, and Rooster targets following up encouraging results from the 2025 exploration program. Assay results are still pending for four holes from the Hammer and Rooster zones. At the Needle property, situated 60 km southwest of the Goose Mine, approximately 450 m were drilled with the program ongoing and assays pending. Results to date in 2026 have not returned any significant values.

Surface Exploration Program

Regional target definition was supplemented by an integrated surface exploration program comprised of mapping, prospecting, and the collection of 2,927 till samples, 92 channels (296 samples), and 1,059 rock samples from nine properties including Ailiruk, Goose South, Boot, Boulder, George, Del, Needle, Beech, and Wishbone. Channel sample results from Ailiruk are encouraging and include up to 3.94 g/t gold over 6.3 m. In addition, shallow Rotary Air Blast (“RAB”) drilling was carried out over four areas with 183 holes drilled and 386 samples collected. Results of RAB drilling will aid in identifying prospective lithology below glacial till cover and guide future efforts towards mineralized bedrock. The completed surface exploration has generated additional regional and near-mine targets for further evaluation and drill testing in 2027.

Qualified Person Statement

Peter D. Montano, P. Eng., Vice President, Operations and Project Development, a qualified person under NI 43-101, has approved the scientific and technical information related to operations matters contained in this news release.

Andrew Brown, P.Geo., Vice President, Exploration, a qualified person under NI 43-101, has approved the scientific and technical information related to exploration and mineral resource matters contained in this news release.

Quality Assurance/Quality Control on Sample Collection and Assaying

The primary laboratory utilized for the Back River Gold District drilling program in 2026 is ALS laboratory in North Vancouver, Canada. Core samples are prepared at the ALS preparation facility in Yellowknife with representative pulp samples sent to the ALS North Vancouver laboratory for gold analysis. Gold is analyzed by a fire assay/atomic absorption spectrometry (“FA/AAS”) finish using a 50-gram subsample of the coin pulp. FAs were finished with AAS, and samples with higher grades that exceeded the maximum detection limit of AAS received a supplemental gravimetric (“GRAV”) finish. All samples over 3,000 parts per billion are analyzed by FA/GRAV using a 50-gram subsample of the coin pulp. Bureau Veritas Minerals in Vancouver, Canada, is the umpire laboratory.

Quality assurance and quality control procedures include the systematic insertion of blanks and standards into the core sample strings. The results of the control samples are evaluated on a regular basis with batches re-analyzed and/or resubmitted as needed. All results stated in this announcement have passed B2Gold's quality assurance and quality control protocols.
