Otjikoto Mine – Namibia (1)

The Otjikoto Mine is located in the north-central part of Namibia, approximately 300 km north of the country’s capital, Windhoek. Otjikoto is the largest gold producer in the country.

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. 

The Otjikoto Mine in Namibia had a strong second half in 2021 and finish to the year, resulting in new quarterly and annual gold production records. For full-year 2021, the Otjikoto Mine produced an annual record of 197,573 ounces of gold, near the upper end of its guidance range (of between 190,000 - 200,000 ounces), and 18% (29,532 ounces) higher compared to 2020. In the fourth quarter of 2021, the Otjikoto Mine produced a quarterly record of 78,681 ounces of gold, in-line with budget, and significantly higher by 96% (38,476 ounces) over the fourth quarter of 2020. As planned, with the completion of the pre-stripping campaigns at the Wolfshag and Otjikoto pits in the first half of 2021, Otjikoto's gold production increased significantly in the second half of 2021, as mining reached the higher-grade zone at the base of the Wolfshag Pit in the third quarter of 2021.

For full-year 2021, Otjikoto's cash operating costs were $493 per ounce produced ($511 per ounce sold), well within its guidance range (of between $480 - $520 per ounce). Otjikoto's cash operating costs on a per ounce basis was in-line with budget in 2021 as a result of higher than budgeted production together with only slightly above budgeted operating costs. Otjikoto's 2021 operating costs were impacted by inflation driven higher than budgeted fuel prices and a stronger than budgeted Namibian dollar, which were offset by higher than budgeted capitalized pre-stripping resulting in an overall cost per ounce which was in-line with budget. 

Otjikoto's AISC for the full-year 2021 were $908 per gold ounce sold (2020 - $920 per ounce sold), above the high end of its guidance range (of between $830 - $870 per ounce), due to higher than budgeted sustaining capital expenditures ($8 million higher than budgeted, consisting of higher than budgeted pre-stripping of $5 million and mobile equipment rebuilds of $3 million) partially offset by higher than budgeted ounces sold and realized fuel derivative gains. 

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

The Otjikoto Mine is expected to produce between 175,000 - 185,000 ounces of gold in 2022 at cash operating costs of between $740 - $780 per ounce and AISC of between $1,120 - $1,160 per ounce.

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.

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.
