About Otjikoto

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

Processed ore is sourced from the Otjikoto pit and the Wolfshag underground mine, supplemented by existing ore stockpiles. Open pit mining operations are scheduled to conclude in the third quarter of 2025, while underground mining operations at Wolfshag are expected to continue into 2027. Exploration results received to date indicate the potential to extend underground production at Wolfshag past 2027, supplementing the processing operations into 2032 when economically viable stockpiles are forecast to be exhausted.

History

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.

Processing Plant

Conventional flowsheet whereby gold is recovered by gravity concentration/intensive leaching and by an agitated cyanide leach/carbon-in-pulp process for treatment of gravity tailings.

Power

Since commissioning the NamPower grid link, the Otjikoto Mine has reduced its overall processing plant costs by approximately 10%. In addition, the transition away from HFO to a combination of the solar power plant and the national grid will significantly reduce GHG emissions.

  5. Otjikoto Mineral Reserves have an effective date of December 31, 2023 and have been prepared by Peter Montano, P.E., a Qualified Person under NI 43-101. Mineral Reserves to be mined using open pit methods or in stockpiles are based on a conventional open pit mining method, gold price of US$1,600/oz, metallurgical recovery of 98%, selling costs of US$67.61/oz including royalties and levies, average mining cost of US$3.38/t mined, average processing cost of US$12.75/t processed, and site general costs of US$3.92/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 grade there is a 2.4% decrease in tonnes, a 2.3% reduction in grade, and a 4.6% 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$1,600/oz, metallurgical recovery of 98%, selling costs of US$67.61/oz including royalties and levies, average mining cost of US$109.91/t mined, average processing cost of US$12.75/t processed, general costs of US$3.92/t processed, 10% dilution, and 85% mining recovery. Mineral Reserves that will be mined by underground methods are reported above a cut-off grade of 2.62 g/t Au.

Exploration

On January 31, 2024, the Company announced positive exploration drilling results from the Antelope deposit at the Otjikoto Mine. The Antelope deposit, which comprises of the Springbok Zone, the Oryx Zone, and a possible third structure, Impala, subject to further confirmatory drilling, is located approximately three kilometers south of the Otjikoto open pit.

On June 20, 2024, the Company announced an initial Inferred Mineral Resource estimate for the Springbok Zone, the southernmost shoot of the recently discovered Antelope deposit. Over 36,000 meters have been drilled into the Springbok Zone to date, with 33 holes totaling 16,950 meters completed in 2024, to establish the 50 x 50 meter spacing that informs the initial Inferred Mineral Resource Estimate. Recent drilling at the Springbok Zone remains open southward, indicating additional exploration potential beyond the currently defined resource. The Company determined that the initial Inferred Mineral Resource estimate of 1.75 million tonnes grading 6.91 g/t gold for a total of 390,000 ounces of gold was sufficient to initiate a PEA on development of the deposit by underground mining methods, similar to the Wolfshag deposit.

Subject to the receipt of a positive PEA and necessary permits and approvals, mining of the Sprinbok Zone could begin to contribute to gold production at Otjikoto as early as 2028. An initial budget of $10 million has be approved to de-risk the Antelope deposit development schedule by advancing early work planning, project permits and long lead orders. Exploration of the greater Antelope deposit has the potential to supplement the processing of ore stockpiles at Otjikoto, with an initial goal of adding between 80,000 and 90,000 ounces of additional gold production per year from 2029 through 2032, with potential to extend the mine life further through additional drilling at the Springbok and Oryx Zones at the Antelope deposit.

Mineral Resources that are not Mineral Reserves does not have demonstrated economic viability. There is no guarantee that all or any part of the Mineral Resource will be converted into a Mineral Reserve.

Inferred Mineral Resources are considered too geologically speculative to have mining and economic considerations applied to them that would enable them to be categorized as Mineral Reserves.

A total of $7 million is budgeted for exploration at Otjikoto in 2025. The focus of the exploration program will be drilling to expand and define the Antelope deposit, with a total of 44,000 meters of drilling planned.
