Mike Cinnamond, President and CEO of B2Gold, said, “We are very pleased to provide an operational update for the Goose Mine that demonstrates the significant progress to achieve temporary ore crushing capacity at 3,000 tpd following the fire in April, while progressing the upgrades and repairs to the fixed crushing plant, according to plan. The successful commissioning of the new mobile crushing plant and continued advancement of the Phase 1 upgrades are a testament to the dedication and hard work of our operations, maintenance and project teams. With the crusher repairs and upgrades on track, we remain confident in our ability to achieve 170,000 to 200,000 ounces of gold production at Goose this year and continue to position the site for improved long-term performance and operating flexibility.

Our 2026 Back River Gold District exploration program yielded strong results from the Goose Mine and regional program, aiding our deposit knowledge and mine planning, district-wide target generation, and conversion of near-mine resources. At the Goose Mine, drilling at the Llama deposit and Nuvuyak structure contributed to our goal to infill Mineral Resources, demonstrated the potential to further extend mine life, and identified a prospective new zone, Tattuk, for follow up drilling. At the George Project, strong results from infill drilling strengthened confidence in the continuity of high-grade mineralization that will support resource conversion. We look forward to building upon the results of the 2026 program and advancing opportunities identified district-wide.”

Goose Mine Operations Update

Mobile Crusher Update

As announced on August 6, 2026, the Company purchased and received a new mobile crushing plant to supplement existing crushing capacity while repairs to the fixed crushing plant, as a result of the fire announced earlier in the year, are completed. The new mobile crushing plant arrived on site in July and was commissioned in August. Following commissioning of the new mobile crushing plant, total mobile crushing ore throughput exceeded an average of 3,000 tpd since mid-August, in line with plan. The capital cost for the additional crushing plant and supporting equipment was approximately $16 million.

Phase 1 upgrades to the fixed crushing plant, which include the addition of a run-of-mine mass-flow bin and apron feeder, a new larger jaw crusher and rock breaker, are underway and on track to be commissioned mid-October, the same time repairs from the fire to the conveyor belt are expected to be completed. The Goose fixed crushing plant is expected to have an average daily capacity of 3,200 tpd following the commissioning of the Phase 1 upgrades, which are estimated to incur a total cost of $11 million.

The Company plans to continue to use the new mobile crushing plant (~3,000 tpd) alongside the fixed crushing plant (~3,200 tpd) through October and as weather permits through the winter, to feed the mill and build a stockpile of crushed ore. A semi-permanent enclosure is being erected around the mobile crushing plant to facilitate continued operations of the mobile crusher during the winter months. Phase 2 upgrades to the fixed crushing plant are scheduled for the first half of 2027, at which time the fixed crushing plant is expected to be down for up to 10 weeks while upgrades are completed. The Company expects to build sufficient crushed ore stockpiles prior to the Phase 2 shutdown and utilize the new mobile crushing plant during the upgrade, so that mill operations are not impacted during the shutdown period. Phase 2 crusher upgrades include the installation of larger secondary/tertiary cone crushers, new surge bins with feeders to optimize crusher performance, and upgraded conveyors to support higher throughput. Once complete, the Phase 2 upgrades are expected to increase average crushing capacity to design throughput of 4,000 tpd. While initially acquired to mitigate the impacts of the crusher fire, the new mobile crushing plant will remain on site and be used to provide long-term operational flexibility and additional crushing capacity beyond the completion of the fixed crushing plant upgrades.

Annual Guidance

With the new mobile crusher commissioned and Phase 1 upgrades progressing as planned, the Company remains on track to deliver annual production guidance of 170,000 to 200,000 ounces of gold from the Goose Mine in 2026. Third quarter of 2026 gold production is expected to be broadly in line with first quarter production levels, and fourth quarter of 2026 production is expected to be the strongest quarter of the year, driven by a full quarter of higher tonnes milled and strong mill feed grade.

2026 Back River Gold District Exploration Program Overview

The 2026 exploration program is supported by a budget of $51 million, and includes over 35,000 m of drilling, and regional exploration activities. The program prioritized supporting future mine planning, infill drilling for resource conversion, the identification of new zones of mineralization for follow-up exploration and increasing deposit knowledge. As of August 31, the 2026 Back River Gold District exploration program had completed 75% of the 2026 campaign with a total of 27,493 m of drilling.

More than half of the 2026 exploration budget is focused on activities located at the Goose Mine to infill Inferred Mineral Resources at the Llama deposit and Nuvuyak zone, as well as targeting extensions of known mineralization at the Nuvuyak zone.

The 2026 regional exploration program is focused on mapping, prospecting, and till sampling on the George Project (including the Locale 1 deposit), Ailiruk, Goose, Boot, Needle, and Beech targets and makes up the remainder of the 2026 exploration budget at the Back River Gold District. The goal of the regional work is to further define resources at the Locale 1 deposit, identify new zones of mineralization amenable to open pit mining methods, and follow up on targets defined during the 2025 summer regional exploration program.

All drill results are as of August 31, 2026, unless otherwise noted. Full composite tables detailing drill intercept assay results are provided at the end of this release.

Goose Mine Exploration

The Goose Mine comprises five main deposits: Umwelt, Llama, Llama Extension, Goose Main and Echo, and has defined Indicated Mineral Resources of 15.91 million tonnes grading 7.40 g/t gold totaling 3.79 million ounces (inclusive of Mineral Reserves) and Inferred Mineral Resources of 9.31 million tonnes grading 7.63 g/t totaling 2.28 million ounces. Significant drill hole locations from the 2026 Goose Mine exploration program are shown on the map in Figure 1 and Figure 2.

Figure 1. Goose Mine drill hole locations plan view.

Figure 2. Goose Mine drill hole locations long section with significant intersections labelled.

At the Llama deposit, 28 holes totaling 7,255 m were drilled year-to-date to infill the Inferred Mineral Resources down plunge from the Llama open pit. Results confirm current interpretations of high-grade mineralization with results up to 19.12 g/t gold over 21.23 m from 463.85 m in drill hole 26GSE749Z2 (Figure 3). All assay results from the 2026 drill campaign at Llama have now been received, providing key inputs for upcoming mine-planning work.

The LX Gap is an approximately 300 m long portion of the southeasterly plunging Llama deposit that to date has seen insufficient drilling to confirm the continuity of high-grade mineralization along the entirety of the known 2,000 m of the deposit. The high-grade intersections flanking LX Gap impart confidence in continuity and promote LX Gap as a drill target for the 2027 drilling campaign.

Figure 3. Llama Deposit long section (facing northeast). Significant intersections are labelled and pierce points for drillholes disclosed in this release are outlined in black.

At Goose Main, 16 holes totaling 6,951 m were drilled year-to-date, focused on infill drilling and exploring extensions down plunge and down dip of known mineralization in the Nuvuyak zone. Infill drilling is ongoing with assay results still pending for 10 holes. Results from the 2025 exploration program suggested mineralization continued down plunge of Nuvuyak, and drill hole 26GSE750Z2 was extended to test the geological interpretation of the iron formation hosting the gold mineralization and to evaluate Nuvuyak’s projected continuation down plunge. Results from that hole confirmed high-grade mineralization, with 10.94 g/t gold over 9.95 m from 1,195.90 m on the western limb of the fold. This new discovery, named Tattuk, is approximately 150 m down plunge from Nuvuyak and presents a new opportunity for future resource additions (Figure 4).

Other near-mine exploration targets, including Hackles and Goose Tail, were tested in 2026 with a total of 1,178 m drilled in six drill holes. At the Goose Tail target, 850 m southeast of Goose Main, drilling from three drill holes tested the potential for a small open pit resource target. Assay results are pending for the three 2026 drill holes.

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.

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.

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.
