B2Gold Announces Positive Exploration Results from the Anaconda Area and the Fekola Deposit and an Update on the Fekola Mine Expansion

VANCOUVER, Sept. 16, 2019 /PRNewswire/ - B2Gold Corp. (TSX: BTO, NYSE AMERICAN: BTG, NSX: B2G) ("B2Gold" or the "Company") announces positive drill results from the Mamba zone which is located within the Anaconda area approximately 20 kilometres from the Fekola Mine, as well as positive infill drill results from the Fekola mineral resource area and step out results north of the Fekola resource.

Highlights include:

• Extending the shallow, high-grade saprolite mineralized zone at Mamba by approximately 600 metres to more than one kilometre of strike length
• Discovery of a new wide good grade sulphide zone directly beneath the Mamba saprolite zone. The sulphide zone is open down plunge to the south, indicating the potential for Fekola-type gold deposits
• Successful infill drilling at the Fekola deposit completed, upgrade of the Inferred Mineral Resource (19%) to Indicated status by the fourth quarter of 2019
• Step out drilling continues to extend the Fekola deposit further to the north, which remains open

Recent Exploration

Drilling in 2019 in Mali has been focused on increasing the Anaconda area saprolite resource, testing mineralized zones beneath the shallow saprolite zones, infill drilling the Inferred portion of the Fekola Mineral Resource to Indicated status and expanding the Fekola deposit further to the north. Based on positive drill results, in July, the Company increased the 2019 exploration budget in Mali by $3 million to $20.5 million.    

Anaconda Area (see figure 1 "Mamba long section" below)

B2Gold has completed an 850-hole (24,863 metre) program of combined aircore, diamond and reverse circulation drilling at the Anaconda area, including on the Company's increased land position. Drilling focused mainly on the Mamba zone, located one kilometre east of the Anaconda zone, where the Company previously announced an Inferred Mineral Resource estimate of 767,000 ounces of gold at 1.1 grams per tonne ("g/t") in near-surface saprolite mineralization over 4.5 kilometres and up to 500 metres wide. The initial stage of the program has extended the strike length of known saprolite mineralized structures at Mamba by over 600 metres to over approximately one kilometre. Saprolite mineralization at the Adder zone, 1.2 kilometres to the west of the Mamba zone, remains open to the north. At Mamba, the newly discovered wide zone of sulphide mineralization is contiguous and continuous with the saprolite mineralization and remains open down plunge and to the south, indicating the potential to host Fekola-style sulphide gold deposits.

Recent holes include BNR_010 (61 metres at 2.25 g/t gold from 30 metres) and BNR_005 (39 metres at 3.16 g/t gold from 77 metres), which intersected thick accumulations of good grade saprolite mineralization. Highlights from the sulphide-hosted mineralization include BND_001, which intersected 38.40 metres at 2.40 g/t gold from 72.70 metres directly down plunge from the high-grade saprolite mineralization and 13.95 metres at 2.20 g/t gold from 184.05 metres and hole BNR_002, which intersected 14 metres at 4.50 g/t gold from 109 metres.

These new intersections occur approximately 150 metres up plunge from previous sulphide intercepts on the Mamba zone, which include two holes on the same section: MSD_141(44.00 metres at 1.22 g/t gold from 80.00 metres and 46.20 metres at 1.76 g/t gold from 168.80 metres) and the undercutting hole, MSD_132 (23.22 metres at 1.31 g/t gold from 116.48 metres, 24.50 metres at 4.02 g/t gold from 218.50 metres and 22.80 metres at 1.04 g/t gold from 253.20 metres).  The geometry of this good grade zone of mineralization is to be confirmed with additional drilling.

Highlights from drilling to date include:

Sulphide composites are reported above 0.6 g/t gold cutoff; saprolite composites are reported above a 0.2 g/t gold cutoff.

Fekola Infill Program (see figure 2 "Fekola long section" below)

In October 2018, B2Gold reported an updated Indicated Mineral Resource estimate of 92,810,000 tonnes at 1.92 g/t gold for a total of 5,730,000 ounces of gold, and an Inferred Mineral Resource estimate of 26,500,000 tonnes at 1.61 g/t gold for a total of 1,370,000 ounces of gold (19%), for the Fekola Mine (see news release dated October 25, 2018). A significant portion of the 2019 drilling has been focused on upgrading the Inferred Mineral Resource estimate to Indicated status, with a total of 25,000 metres completed as of August 15, 2019.

Infill drill results to date support the results of the 2018 resource model, which had 19% Inferred Mineral Resources and 81% Indicated Mineral Resources. Furthermore, drill holes FKD_409 (4.03 g/t gold over 30.50 metres from 437.5 metres), FKD_413 (10.44 g/t gold over 19.8 metres from 495.2 metres) and FKD_415 (3.3 g/t gold over 38.2 metres from 467.5 metres)  provide added confirmation that significant intervals of high-grade gold mineralization occur beyond the limits of the 2019 Preliminary Economic Assessment ("PEA") pit shell (see news release dated May 13, 2019), within the deepest portions of the 2018 $1,400/ounce gold resource pit shell. Follow up drilling down plunge from this good grade mineralization has been completed and assays are pending from holes FKD_431 and FKD_432. Mineralization remains open to the north and down plunge. An updated resource model is scheduled for completion the fourth quarter of 2019.

Highlights from the Fekola infill program include:

Composites are reported above a 0.6 g/t gold cutoff. Included high-grade intervals are reported above a 1.0 g/t cutoff.  *PEA denotes holes drilled within a pit shell optimized at $1,300/oz gold (see news release dated May 13, 2019). 1400 denotes holes drilled within $1,400/oz gold resource pit shell (see news release dated October 25, 2018).

Ongoing Exploration

Drilling is ongoing at Fekola, including a reconnaissance program on the Cardinal zone, less than one kilometre west of the Fekola Mine open pit. Drilling on the Anaconda area, to test the extension of the saprolite zones and further explore the sulphide mineralization below is scheduled to recommence in the fourth quarter of 2019. An additional 30,000 metres of drilling is planned for completion before year end and the Company expects to continue with an aggressive exploration program in 2020.

Fekola Mine Expansion Update

On March 26, 2019, B2Gold announced positive results from the Expansion Study PEA for the Fekola Mine. As a result, the Company is proceeding with an expansion project to increase processing throughput by 1.5 million tonnes per annum ("Mtpa") to 7.5 Mtpa from an assumed base rate of 6 Mtpa. The PEA reflected the significant increase in the Fekola Mineral Resource estimate announced on October 25, 2018. Based on the PEA, once this expansion is complete, the Fekola Mine is expected to produce more gold over a longer life, with more robust economics and higher average annual gold production, revenues and cash flows than the previous life-of-mine ("LoM").

Highlights from the PEA include: estimated optimized LoM extended into 2030, including significant estimated increases in average annual gold production to over 550,000 ounces per year during the five-year period 2020-2024 and over 400,000 ounces per year over the LoM (2019-2030), projected gold production of approximately five million ounces over the new mine life of 12 years of mining and processing (including 2019).

The processing upgrade at the Fekola Mine will focus on increased ball mill power, with upgrades to other components including a new cyclone classification system, pebble crushers and additional leach capacity to support the higher throughput and increase operability. Critical path items include ball mill motors and the lime slaker, both of which the Company expects to be commissioned in the third quarter of 2020. In parallel with the expansion, B2Gold has initiated the detailed engineering and construction for the addition of a 30-megawatt solar power plant, which the Company expects will result in reduced operating costs and greenhouse gas emissions. Completion of the solar plant is scheduled for the third quarter of 2020. The current on-site power plant has sufficient capacity to support the expanded processing throughput, with or without the solar plant.

Construction will commence in October 2019 and is scheduled to be completed by the end of July 2020. All major long-lead equipment has been ordered. Detailed engineering and design activities are progressing well and scheduled to be completed by October 2019.

Based on B2Gold's current projections, gold production at the Fekola Mine in 2020 is projected to be approximately 600,000 ounces of gold, primarily due to the addition of a larger mining fleet at Fekola and the optimization of the mining sequence early in 2020, prior to completion of the mill expansion by September 2019, providing access to higher grade portions of the deposit earlier on in the sequence.

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The Expansion Study PEA is preliminary in nature and includes Indicated and Inferred Mineral Resources. Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Consequently, there is no certainty that the Expansion Study PEA will be realized.

Non-IFRS Measures

This news release includes certain terms or performance measures commonly used in the mining industry that are not defined under International Financial Reporting Standards ("IFRS"), including "cash operating costs" and "all-in sustaining costs" (or "AISC"). Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS and should be read in conjunction with B2Gold's consolidated financial statements. Readers should refer to B2Gold's management discussion and analysis, available on the Websites, under the heading "Non-IFRS Measures" for a more detailed discussion of how B2Gold calculates such measures and reconciliation of certain measures to IFRS terms.

Cautionary Note to United States Investors

The Company has prepared its public disclosures in accordance with Canadian securities laws, which differ in certain respects from U.S. securities laws. In particular, this news release may refer to "mineral resources", "measured mineral resources", "indicated mineral resources" or "inferred mineral resources". While these categories of mineralization are recognized and required by Canadian securities laws, they are not recognized by the SEC and are not normally permitted to be disclosed in SEC filings by U.S. companies. U.S. investors are cautioned not to assume that any part of a "mineral resource", "measured mineral resource", "indicated mineral resource" or "inferred mineral resource" will ever be converted into a "reserve." In addition, "reserves" reported by the Company under Canadian standards may not qualify as reserves under SEC standards. Under SEC standards, mineralization may not be classified as a "reserve" unless the mineralization can be economically and legally extracted or produced at the time the "reserve" determination is made. Accordingly, information contained or referenced in this news release containing descriptions of the Company's mineral deposits may not be compatible to similar information made public by U.S. companies subject to the reporting and disclosure requirements of U.S. federal securities laws, rules and regulations. "Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Historical results or feasibility models presented herein are not guarantees or expectations of future performance.
