Certain portions of the following information are derived from and based on the technical report entitled “Otjikoto Gold Mine Namibia NI 43-101 Technical Report” (click here) with an effective date of December 31, 2018, and was prepared by Mr. Tom Garagan, P.Geo., Mr. Peter Montano, P.E., Mr. Ken Jones, P.E. and Mr. John Rajala, P.E. of B2Gold, and from the Company's most recent AIF, dated March 20, 2019 (click here) and are based on the assumptions, qualifications and procedures set out therein.

1. Mineral Resources have been classified using the Canadian Institute of Mining  ("CIM") Standards. Mineral Resources are reported inclusive of those Mineral Resources that have been modified to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
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. Mineral Resources are reported on a 100% project and a 90% attributable basis; the remaining 10% interest is held by EVI.
4. The Qualified Person for the resource estimate is Tom Garagan, P.Geo., our Senior Vice President, Exploration.
5. The Qualified Person for the stockpile estimate is Peter Montano, P.E., our Project Director.
6. Mineral Resource estimates that are amenable to open pit mining methods assume a gold price of US$1,500/oz, metallurgical recovery of 98%, and operating cost estimates of US$2.29/t mined (mining), US$12.26/t processed (processing) and US$3.15/t processed (general and administrative).
7. Mineral Resources that are amenable to open pit mining are reported at a cut-off of 0.40 g/t Au. Mineral Resources that are amenable to underground mining are reported at cut-off grade of 2.4 or 3 g/t Au.

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. Mineral Reserves are reported on a 100% project and a 90% attributable basis; the remaining 10% interest is held by EVI.
4. The Qualified Person for the Mineral Reserve estimate within open pits and stockpiles is Peter Montano, P.E., our Project Director. The Qualified Person for the Mineral Reserve estimate that will be mined using underground methods is Kyle Foster, P. Eng., our Senior Mine Engineer.
5. Mineral Reserves that will be mined by open pit methods and Mineral Reserves held in stockpiles assume a conventional open pit mining method, gold price of US$1,350/oz, metallurgical recovery of 98%, selling costs of US$57.44/oz including royalties and levies, average mining cost of US$2.29/t mined, average processing cost of US$12.26/t processed, and site general costs of US$3.15/t processed. Dilution and ore loss were applied through block averaging such that at a cut-off of 0.45 g/t Au, there is a 2.3% decrease in tonnes, a 2.2% reduction in grade and a 4.4% reduction in ounces when compared to the Mineral Resource model. Mineral Reserves are reported at a cut-off grade of 0.45 g/t Au.
6. Mineral Reserves that will be mined by underground methods assume a modified transverse longhole stopping mining method, gold price of US$1350/oz, metallurgical recovery of 98%, selling costs of US$57.44/oz including royalties and levies, average mining cost of US$83.60/t mined, average processing cost of $12.26/t processed, general costs of $3.15/t processed, 10% dilution, and 90% mining recovery. Underground Mineral Reserves are reported above a cut-off grade of 2.68 g/t Au.
