Certain portions of the following information are derived from and based on the technical report entitled “NI 43-101 Technical Report Feasibility Study: Otjikoto Gold Project, Province of Otjozondjupa, Republic of Namibia” (click here) that has an effective date of February 25, 2013, and was prepared by William Lytle, P.E., Tom Garagan, P. Geo., Hermanus Kriel, Pr. Eng., Glenn Bezuidenhout, Pr. Eng., FSAIMM and Guy Wiid, Pr. Eng., among others, 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 Reserves have been classified using the CIM Standards (refer to the Company's AIF, dated March 20, 2019 – click here for additional information regarding these Mineral Reserves).
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 basis; of which a 10% interest is held by EVI.
4. The Qualified Person for the reserve estimate is Peter Montano, P.E., who is B2Gold's Project Director. 
5. Mineral Reserves that will be mined by open pit methods assume a gold price of US$1,250/oz, metallurgical recovery of 98%, selling costs of $51.44/oz (including royalties and levies), and operating cost estimates of US$2.29/t mined (mining), US$12.99/t processed (processing) and US$3.25/t processed (general and administrative). 
6. Dilution and ore loss was applied through block averaging such that at a cutoff 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.
7. Mineral Reserves are reported at a cutoff of 0.45 g/t Au.

1. Mineral Reserves have been classified using the CIM Standards (refer to the Company's AIF, dated March 20, 2019 – click here for additional information regarding these Mineral Reserves). 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 basis; of which a 10% interest is held by EVI.
4. The Qualified Person for the resource estimate is Tom Garagan, P.Geo., who is B2Gold's Senior Vice President, Exploration. 
5. The Qualified Person for the stockpile estimate is Peter Montano, P.E., who is B2Gold's Project Director.
6. Mineral Resource estimates that are amenable to open pit mining methods assume a gold price of US$1,400/oz, metallurgical recovery of 98%, and operating cost estimates of US$2.23/t mined (mining), US$12.85/t processed (processing) and US$3.24/t processed (general and administrative).
7. Mineral Resources that are amenable to open pit mining are reported at a cutoff of 0.40g/t Au. Mineral Resources that are amenable to underground mining are reported at cutoff of 2.6 g/t Au.
