B2Gold Corp. (TSX: BTO) (NYSE AMERICAN) (BTG, NSX: B2G) is pleased to announce positive exploration drilling results from its inaugural drilling campaign at the Back River Gold District in Nunavut and provide an update on construction and mining at the Goose Project.
Exploration and Infill Drill Results Highlights
In the second quarter of 2023, B2Gold approved a US$20 million exploration budget for the balance of 2023 to complete approximately 25,000 m of drilling on the Back River Gold District, significantly higher than historical annual exploration expenditures. Drilling at the Goose Project began in early August 2023 with two drill rigs, testing the Llama deposit down-plunge for mineral resource confirmation and mineral resource expansion, and testing regional targets that were developed based on structural modelling and geophysical re-processing. The objective for drilling at the George Project was to test several targets over a strike length of 10 kilometers (“km”).
As of the end of October 2023, B2Gold had completed 17,595 m of drilling over 51 drill holes on the Goose Project, and a further 6,010 m of drilling over 26 drill holes on the George Project.

Goose Project Exploration
The Goose Project consists of five known deposits with existing mineral resources, Umwelt, Llama, Goose, Echo and Nuvuyak, which occur along a strike length of 8 km. The Company believes that exploration upside exists on all known deposits that are open at depth, as well as several zones of interest that remain relatively untested within the footprint of the favorable host stratigraphy. Ongoing structural and data review will form the basis of an aggressive 2024 exploration season to drill test several zones of interest.
As of October 31, 2023, assay results have been received from 16 of the 51 drilled holes at the Goose Project.
At the Umwelt deposit, drilling was designed to confirm geometry and grade continuity of high-grade shoots below the planned open pits. Results received to date confirm the continuity of high-grade mineralization in the hinge and short limb of the Umwelt antiform and will provide critical information for underground mine design planning. Since the end of October, a further 17 drill holes are planned for completion in 2023.
At the Llama deposit, which outcrops 1,500 m north of the Umwelt deposit, two holes were drilled, which have confirmed the extension of the structure at depth. Drill hole 23GSE-626 returned an impressive 7.79 g/t over 22.00 m from 729.00 m, including a higher grade intercept of 11.22 g/t over 14.40 m, and was designed to test the favorable stratigraphy 660 m vertically, and 110 m down plunge beyond previously reported inferred mineral resources. Drill hole 23GSE-614 returned high-grade narrow results on the less drilled east limb of the Llama deposit including 32.75 g/t gold over 2.05 m from 365.95 m.

Notes:
The Goose Project drill program will continue until mid-December 2023 to target high-grade plunging shoots at Umwelt. The drill program in 2024 will start late in the first quarter of 2024 and focus on drilling several zones on the Goose Project to expand known mineral resources and test new areas for mineral resource upside potential.
George Project Exploration
At the George Project, located 50 km northwest of the Goose Project, a 2023 spring and summer drill program tested multiple targets along a 10 km strike length to evaluate mineralization controls and upside potential with 6,010 m drilled over 26 drill holes.
The George Project represents three sub-parallel zones of tightly folded banded iron formation that stretch over 20 km in strike length.
Drill results from the 2023 campaign reflect similar widths and grades as those reported by previous operators, with several holes from the 2023 program extending mineralization along strike and between known zones of mineral resources. Drill hole 23GRL-216 returned encouraging results, intersecting 19.17 g/t gold over 7.50 m from 36.60 m, very close to surface between two known deposits (LCPS and LCPN). In the southwestern part of the belt in the GH area, drill holes 23GRL-207 and 23GRL-211 extended mineralization to the south of the existing mineral resource pit shell.

Quality Assurance/Quality Control on Sample Collection and Assaying
The primary laboratory utilized for the Back River Gold District drilling program in 2023 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. Activation Laboratories Ltd. (Actlabs) in Kamloops, 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.
Goose Project, Nunavut, Construction and Mining Update
Construction at the Goose Project is progressing on track, with the project remaining on schedule for first gold pour in the first quarter of 2025. Open pit mining is underway at the Echo Pit and underground development work on the Umwelt deposit is ongoing.
The first concrete pour was completed in July 2023 and concrete and steel work in the mill area to date are progressing ahead of schedule. Erection of the structural steel for the mill building, power house and truck shop is well underway, and cladding is advancing quickly on the mill building with the roof complete and over 50% of the building cladding completed. Cladding of both the power house and truck shop has begun. Enclosure of these three buildings will allow for work to continue through the colder months and remain on schedule. Additionally, it is expected that the ball mill will be set in place in December 2023, approximately six months ahead of schedule, allowing the focus for the start of 2024 to shift to piping and mechanical systems.
In July 2023, Phase 1 of the accommodation complex opened, including sleeping quarters, office area, medical center, gymnasium, kitchens and water treatment. Phase 1 of the accommodation complex includes 310 beds at the permanent site location. In September 2023, the earthworks necessary to extend the airstrip to 5,000 feet were completed. The extension of the airstrip will allow large capacity, fully loaded passenger planes to land at the Goose Project throughout the 2024 construction campaign. In mid-October, the 2023 sealift was successfully completed, with a total of six ships received from global ports bringing a total shipping volume of 90,000 cubic meters of dry cargo and 24,000,000 liters of arctic grade diesel fuel to the Marine Laydown Area (“MLA”). The 2023 sealift included all planned material sealift materials required for the successful construction, commissioning and mining of the Goose Project.
The 163 km winter ice road between the MLA and the Goose Project is scheduled to operate between February and the end of April. The 2024 WIR construction team will mobilize to the MLA and Goose Project sites in early and mid-December 2023, with the construction of the 2024 WIR expected to begin in December 2023. At the MLA, preparations for the 2024 WIR are well underway, including maintenance and preparation of the WIR construction and haulage fleet and staging all materials for shipment on the WIR to the Goose Project site.
Open pit mining of the Echo Pit is underway and will produce construction fill, stockpile ore and provide tailings storage capacity. Open pit mining of the Umwelt Pit will commence in the first quarter of 2024 and will produce much of the commissioning ore as well as future tailings storage. Underground development of the Umwelt deposit is also underway, currently at a depth of 142 vertical meters below surface. Breakthrough of the initial ventilation raise has been completed and development towards the ore zones is in progress with more than 2,100 meters of lateral development completed to date.
B2Gold recognizes that respect and collaboration with the Kitikmeot Inuit Association (“KIA”) is central to the license to operate in the Back River Gold District and will continue to prioritize developing the project in a manner that recognizes Inuit priorities, addresses concerns, and brings long-term socio economic benefits to the Kitikmeot Region. B2Gold looks forward to continuing to build on its strong collaboration with the KIA and Kitikmeot Communities.
