B2Gold Announces Positive Exploration Drilling Results from the Fekola Regional Area

B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) ("B2Gold" or the "Company") is pleased to announce additional positive exploration drilling results from the Fekola Regional area in Mali, located approximately 25 kilometers ("km") north and northeast of the Fekola Mine. The Fekola Regional area, comprised of the Anaconda Area (Bantako North and Menankoto permits), the Bakolobi permit, and the Dandoko permit, forms part of the Fekola Complex, which also includes the Medinandi permit that hosts the Fekola Mine and the Cardinal Zone.

Highlights

• At the Mamba Zone, exploration drilling in 2023 has been focused on saprolite mineral resource conversion and expanding high grade sulphide mineralization shoots.
  • Hole MSD_241 returned 8.60 grams per tonne ("g/t") gold over 46.40 meters ("m") from 443.30 m (sulphide), further establishing the continuity of the high grade sulphide shoot in Mamba Main Zone. Hole MSD_241 is one of the highest gram-meter intercepts drilled to date at the Anaconda Area.

• At the Cobra and Taipan zones, mineralization is defined over an 8-kilometer strike extent, from the southern portion of the Menankoto permit and continuing on to the Bakolobi permit .
  • Hole BKR_165 returned 5.01 g/t gold over 13.00 m from 57.00 m including 7.05 g/t gold over 9.00 m from 61.00 m (sulphide). The Cobra and Taipan zones remain open both along strike and at depth.

• At the Dandoko permit, infill drilling has validated the known high grade saprolite zone at Seko and defined additional sulphide mineralization.
  • Hole DDSK23_159 returned 4.40 g/t gold over 51.00 m from 44.00 m (saprolite), and hole DDSK23_154 returned 4.57 g/t gold over 36.50 m from 82.00 m (sulphide). Drilling at Dandoko will continue with the objective to expand known saprolite and sulphide mineralization.

• An updated Anaconda Area Mineral Resource estimate, incorporating an additional approximately 120,000 meters of drilling, is underway and anticipated to be completed in Q2 2023.
  • To allow for incorporation of this updated resource estimate, the engineering study of a stand-alone mill and oxide processing facilities at Fekola Regional (Anaconda Area) is now expected in the fourth quarter of 2023. In addition, Fekola Complex optimization work continues to maximize project value from all the various oxide and sulphide material sources including the Fekola Pit, Fekola Underground, Cardinal Pit, and the Bantako North, Menankoto, Bakolobi and Dandoko permits.

2023 Mali Exploration Drilling Program

In 2023, B2Gold is conducting a $35 million exploration program on the Fekola Complex. The initial focus of this year's 178,000 m drill program has been the Anaconda Area, which includes the Mamba, Adder, Anaconda, Cascabel, Boomslang, Taipan and Cobra zones.

Of the 85,000 m of drilling completed to date in 2023, approximately 39,000 m of infill drilling has been allocated to the Anaconda Area to facilitate an upgrade of the Inferred portion of the March 2022 Mineral Resource estimate to an Indicated category. Assays from this infill drilling program have been received and are being incorporated into to an updated Mineral Resource estimate, scheduled for completion by the end of the second quarter of 2023.

Anaconda Area Exploration

Mamba Zone (Bantako North and Menankoto permits)

As a significant contributor to the combined mineral resources in the Anaconda Area, Mamba has been the subject of a focused campaign of infill drilling, with approximately 30% of the 17,992 m completed to date in 2023 being directed at resource class conversion within the oxide portions of Mamba. In addition, exploration for high grade sulphide mineralization continues to be an important part of the 2023 drilling program. Hole MSD_241 returned 8.60 g/t gold over 46.40 m, from 443.30 m (sulphide) and Hole BND_135 returned 5.87 g/t gold over 22.40 m, from 335.70 m (sulphide). These holes are consistent with previous intercepts in the high grade shoot below the March 2022 Mineral Resource pit boundary and will form the basis for follow up drilling later in 2023. Mineralization remains open along this shallow plunging zone.

Select new results from the Mamba Zone exploration drilling include:

Note: Sulphide composites above 0.6 g/t gold cutoff, applying a maximum internal dilution of 5 m. Higher grade including intervals are reported above a cutoff of 1.0 g/t gold, applying a maximum internal dilution of 3 m. Saprolite composites are reported above a 0.2 g/t gold cutoff, applying a maximum internal dilution of 3 m. Results are uncapped. True width not known at this time.

Cobra and Taipan Zones (Menankoto and Bakolobi permits)

Year to date, 19,700 m of drilling have been completed on Cobra, the majority of which will contribute to the upgrade of the existing Inferred Mineral Resource estimate from March 2022. Much of this drilling has been completed on the Bakolobi portion of the Cobra Zone, which adds additional strike extent to the dimensions of Cobra relative to the March 2022 Mineral Resource estimate.

The Cobra Zone was previously documented over 8 km of known strike extent, from Menankoto to the southern end of the Bakolobi permit. The southernmost 2.5 km of the Cobra Zone are now believed to be a separate structure, which is currently being explored as the Taipan Zone. Recent drilling on Cobra and Taipan have returned encouraging intervals of saprolite and sulphide mineralization. Hole BKR_165 returned 5.01 g/t gold over 13.00 m, from 57.00 m (sulphide) and Hole BKR_233 returned 1.74 g/t gold over 33.00 m, from 74.00 m (sulphide).

2023 Fekola Regional Exploration

At present, 11 drills are deployed in West Mali undertaking a mix of infill drilling on the sulphide mineralization at Mamba, exploration drilling along the Cobra and Taipan zones, and aircore and auger reconnaissance drilling of regional targets near Dandoko. At Mamba, local condemnation drill programs in support of mine planning are scheduled to be completed in May and June. In the second half of 2023, upwards of 40,000 m of drilling is planned in the Fekola Regional area targeting saprolite and sulphide resource expansion.

Fekola Regional Development Update

Based on the 2022 Anaconda Area Mineral Resource estimate and B2Gold's preliminary planning, the Company demonstrated that the Anaconda Area could provide selective higher grade saprolite material (average annual grade of up to 2.2 g/t gold) to be trucked approximately 20 km and fed into the Fekola mill at a rate of up to 1.5 million tonnes per annum. Trucking of selective higher grade saprolite material from the Anaconda Area to the Fekola mill will increase the ore processed and has the potential to generate approximately 80,000 to 100,000 ounces of initial gold production per year from Fekola Regional sources (Fekola Regional Phase I). Initial saprolite production is expected to commence from the Bantako North permit starting in the third quarter of 2023 and is expected to contribute approximately 18,000 ounces of gold in 2023 with Fekola Regional production levels continuing to ramp-up through 2024.

In the first quarter of 2023, the Company invested $15 million in the development of Fekola Regional (Anaconda Area) saprolite mining including road construction, mine infrastructure, and mining equipment. For 2023, the Company has budgeted a total of $63 million for Fekola Regional development. The construction mobile equipment fleet is now in operation, and construction of the haul roads and mining infrastructure (warehouse, workshop, fuel depot, and offices) is on schedule to support saprolite production from the Bantako North permit area as early as the third quarter of 2023. Production from Bantako North is contingent upon receipt of all necessary permits, which are expected tobe received in the second quarter of 2023.

Preliminary results of a Fekola Complex optimization study, coupled with 2022 exploration drilling results, indicate that there is a significant opportunity to increase gold production and resource utilization with the addition of oxide processing capacity. The Company is progressing an engineering study of a Fekola Regional stand-alone mill and oxide processing facilities (expected to be located on the Anaconda Area). Construction of a stand-alone oxide mill would constitute Phase II of the Fekola Regional Development Plan. The engineering study will be based on processing 4 Mtpa of saprolite and transitional (oxide) resources. The current Anaconda Area Mineral Resource estimate, released in March 2022 and based on the results of exploration drilling completed up to January 11, 2022, included Indicated Resources of 32.4 million tonnes at 1.08 g/t gold for 1.13 million ounces of gold, all of which was weathered oxide ore, and Inferred Resources that included 19.1 million tonnes of oxide ore at 0.81 g/t gold for 0.50 million ounces of gold, and 44.6 million tonnes of sulphide ore at 1.25 g/t gold for 1.79 million ounces of gold. Since that date through March 31, 2023, the Company has completed approximately 120,000 m of drilling at the Anaconda Area, which included infill drilling to upgrade a significant portion of the Inferred oxide resources to the Indicated category, as well as extending both oxide and sulphide resources in the area. An updated Anaconda Area Mineral Resource estimate is currently underway and scheduled to be completed by the end of the second quarter of 2023. Consequently, to allow for incorporation of this updated Mineral Resource estimate into the engineering study, results of the study are now expected in the fourth quarter of 2023. In addition, Fekola Complex optimization work continues to maximize project value from all the various oxide and sulphide material sources including the Fekola Pit, Fekola Underground, Cardinal Pit, and the Bantako North, Menankoto, Bakolobi and Dandoko permits. The Company's conceptual analysis indicates that the combined Fekola Mine and Fekola Regional processing facilities could have the potential to produce more than 800,000 ounces of gold per year from the Fekola Complex, subject to delineation of additional mineral resources and development, completion of feasibility studies, and the receipt of all necessary regulatory approvals and permits.

QA/QC on Sample Collection and Assaying

The primary laboratories for Fekola are SGS Laboratories in Bamako, Mali and Bureau Veritas Laboratories in Abidjan, Cote d'Ivoire. Periodically, exploration samples will be analyzed at the Fekola Mine laboratory. At each laboratory, samples are prepared and analyzed using 50-gram fire assay with atomic absorption finish and/or gravimetric finish. Umpire assays are used to monitor lab performance monthly.

Quality assurance and quality control procedures include the systematic insertion of blanks, standards and duplicates into the core, reverse circulation and aircore drilling 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.
