B2Gold's Gramalote feasibility study shows robust economics with 22.4% IRR at $2,500/oz gold, supporting a viable 177,000 oz/year operation with manageable capital requirements.

The feasibility study for B2Gold's Gramalote project in Colombia reveals an economically viable gold mine with compelling metrics. The $941 million after-tax NPV (at 5% discount rate) and 22.4% IRR at $2,500/oz gold price indicate a project that significantly exceeds typical mining investment thresholds of 15% IRR. The economics become even more attractive at the current spot price of $3,300/oz, with NPV jumping to $1.72 billion and IRR to 33.5%.

The capital intensity is relatively efficient with $740 million construction capital yielding a 177,000 oz annual production over the 13-year life of project. This translates to approximately $4,180 per annual ounce of production capacity, which is competitive for new gold projects. The 3.4-year payback period (at $2,500/oz) is favorable by industry standards.

The all-in sustaining costs (AISC) of $985/oz positions Gramalote in the lower half of the global cost curve, providing significant operating margin at current gold prices. The project benefits from high metallurgical recoveries of 95.7%, which is exceptional for a gold operation and enhances economic viability.

The initial five years show particularly strong economics with higher grade (1.23 g/t gold vs. life-of-mine 0.96 g/t) and lower AISC ($851/oz). This front-loading of value reduces financial risk and improves financing prospects. The project has been de-risked through 270,000 meters of drilling and extensive technical studies.

Key challenges include permit modifications required for the medium-scale project design, with an estimated 12-18 month timeline. The technical transition from oxide to sulfide processing is well addressed in the processing design with conventional crushing, grinding, flotation, and carbon-in-pulp recovery.

The $444 million post-construction capital requirement is substantial but staged over the project life. Overall, Gramalote represents a technically sound, economically attractive development opportunity that could meaningfully increase B2Gold's production profile and cash flow generation.

VANCOUVER, British Columbia, July 14, 2025 (GLOBE NEWSWIRE) -- B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) (“B2Gold” or the “Company”) is pleased to announce the positive results of a Feasibility Study (“FS”) on its 100% owned Gramalote gold project located in the Department of Antioquia, Colombia (the “Gramalote Project”).

Feasibility Study Overview

The Gramalote Project is located in central Colombia, approximately 230 kilometers (“km”) northwest of Bogota and 100 km northeast of Medellin, in the Province of Antioquia, which has expressed a positive attitude towards the development of responsible mining projects in the region. Following B2Gold’s consolidation of the Gramalote Project in October 2023, B2Gold completed a detailed review including the higher-grade core of the mineral resource, facility size and location, power supply, mining and processing options, tailings design, resettlement, potential construction sequencing and camp design to identify potential cost savings to develop a medium-scale project. The results of the review allowed the Company to determine the optimal parameters and assumptions for this FS.

The FS, with an effective date of April 1, 2025, was prepared by B2Gold and evaluates recovery of gold from an open pit mining operation that will move up to approximately 97,000 tonnes per day (“tpd”) (35.5 Mtpa), with an approximately 16,500 tpd (6.0 Mtpa) processing plant that includes crushing, grinding, flotation, with fine grinding of the flotation concentrate and agitated leaching of the flotation concentrate followed by a carbon-in-pulp recovery process to process doré bullion. The Mineral Reserve estimate for the Gramalote Project that forms the basis for the FS includes Probable Mineral Reserves of 76.7 million tonnes grading 0.96 g/t gold for a total of 2,360,000 ounces of contained gold.

The FS assumptions include revenues using a gold price of $2,500 Gold Price over the Life of Project, a fuel price approximately 10% higher than the expected post-subsidy price, and current prices for reagents, labour, power and other consumables. The key results of the FS are presented in the following tables:

^_Notes:

^{_{1.  Mineral Reserves have been classified using the CIM Standards.
2.  All tonnage, grade and contained metal content estimates have been rounded; rounding may result in apparent summation differences between tonnes, grade, and contained metal content.
3.  The Mineral Reserves have been prepared by Peter Montano, P.E., our Vice President, Projects, and a Qualified Person under NI 43-101.
4.  Mineral Reserves are reported on a 100% basis.
5.  Mineral Reserves are based on a conventional open pit mining method, gold price of $1,750 per ounce, metallurgical recovery averaging 95.6%, selling costs of $60.00 per ounce including royalties, average mining cost of $2.70 per tonne mined, average processing cost of $8.50 per tonne processed, and average site general costs of $3.80 per tonne processed. For Mineral Reserve reporting, the Resource model with 15 x 5 x 10 m parent blocks and 5 x 0.2 x 5 m sub-blocks was regularized to 15 x 5 x 10m blocks. For Indicated blocks within the feasibility reserve pit, above a cutoff of 0.40g/t Au, the regularized model compared to the resource model is +1.2% on tonnage, -4.6% on grade and -3.5% on contained gold. No additional dilution or ore loss has been applied for final reserve reporting.
6.  Mineral Reserves are reported above a cut-off grade of 0.40 g/t of sulphide ore. Oxide material is not processed.}}

Gramalote Project Next Steps

The Gramalote Project will continue to advance resettlement programs, establish coexistence programs for small miners, work on health, safety and environmental projects and continue to work with the government and local communities on social programs.

Due to the desired modifications to the processing plant and infrastructure locations, a Modified Work Plan and Modified Environment Impact Study are required. B2Gold has commenced work on the modifications and expects them to be completed and submitted in late 2025 and early 2026, respectively. If B2Gold makes the decision to develop the Gramalote Project as an open pit gold mine, B2Gold would utilize its proven internal mine construction team to build the mine and mill facilities.
