B2Gold acquired the Company’s first African gold development project, the Otjikoto Gold Project, through a merger with Auryx Gold Corp. in December 2011. The Company received the Otjikoto Mining Licence in December 2012, and construction of the Otjikoto Mine commenced in April 2013. Within approximately 19 months, the first gold pour occurred on December 11, 2014, ahead of schedule.

Development of the Wolfshag underground mine continues to progress with stope ore production expected to commence in early 2022. The initial underground Mineral Reserve estimate for the down-plunge extension of the Wolfshag deposit included 210,000 ounces of gold in 1.2 million tonnes of ore at 5.57 g/t gold.

For full-year 2021, the Otjikoto Mine remains on track to produce between 190,000 - 200,000 ounces of gold. Otjikoto's cash operating costs are expected to be within the guidance range of between $480 and $520 per ounce and AISC are expected to be at or above the upper end of Otjikoto's guidance range of $830 to $870 per ounce.

Notes: (Click to expand)

1. Mineral Resources have been classified using the 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 estimates 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$1,800/oz, metallurgical recovery of 98%, and operating cost estimates of US$2.27/t mined (mining), US$12.06/t processed (processing) and US$3.07/t processed (general and administrative).

7. Mineral Resources that are potentially amenable to open pit mining are reported at a cut-off of 0.26 g/t Au. Mineral Resources that are potentially amenable to underground mining are reported at cut-off grades of 1.7 or 2.7 g/t Au.

Otjikoto Probable Mineral Reserves Statement:

	100% Project Basis			Attributable Ownership Basis

1. Mineral Reserves have been classified using the CIM Standards and have an effective date of December 31, 2020.

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 Randy Reichert, P. Eng., our Vice President Operations.

5. Mineral Reserves that will be mined by open pit methods or are in stockpiles, are based on a conventional open pit mining method, gold price of US$1,500/oz, metallurgical recovery of 98%, selling costs of US$63.49/oz Au including royalties and levies, average mining cost of US$2.27/t mined, average processing cost of US$12.06/t processed, and site general costs of US$3.07/t processed. Reserve model dilution and ore loss was applied through whole block averaging such that at a 0.45 g/t Au cut-off 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 that will be mined by open pit methods or are in stockpiles are reported above 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 stoping mining method, gold price of US$1,350/oz, metallurgical recovery of 98%, selling costs of US$63.49/oz including royalties and levies, average mining cost of US$84.83/t mined, average processing cost of $12.06/t processed, general costs of $3.07/t processed, 10% dilution, and 90% mining recovery. Mineral Reserves that will be mined by underground methods are reported above a cut-off grade of 2.68 g/t Au.
