For 2024, the Otjikoto Mine in Namibia, in which B2Gold holds a 90% interest is expected to process a total of 3.4 million tonnes of ore at an average grade of 1.77 g/t gold with a process gold recovery of 98.0%.
“Processed ore will be sourced from the Otjikoto pit and the Wolfshag underground mine, supplemented by existing medium and high-grade ore stockpiles,” the company announced last week.
The mine performed well during the first quarter of 2024, producing 45,416 ounces of gold, above expectations as a result of higher than anticipated mill feed grade. For the first quarter of 2024, mill feed grade was 1.74 g/t, mill throughput was 0.83 million tonnes, and gold recovery averaged 98.5%.
“Ore production from the Wolfshag underground mine for the first quarter of 2024 averaged over 1,500 tonnes per day at an average grade of 4.06 g/t gold. As of the beginning of 2024, the Probable Mineral Reserve estimate for the Wolfshag deposit includes 100,000 ounces of gold in 0.6 million tonnes of ore at an average grade of 5.02 g/t gold.
“Open pit mining operations at the Otjikoto Mine will continue to ramp down in 2024 and conclude in 2025, while processing operations are expected to continue until economically viable stockpiles are exhausted in 2031. Underground operations are currently projected to continue until 2026 with potential to extend underground operations if the ongoing underground exploration program is successful in identifying more underground mineral deposits,” the miner said.
On January 31, 2024, the Company announced positive exploration drilling results from the Antelope deposit at the Otjikoto Mine. The Antelope deposit, comprised of the Springbok Zone, the Oryx Zone, and a possible third structure, Impala, subject to further confirmatory drilling, is located approximately three km south of the Otjikoto open pit. The Antelope deposit has the potential to be developed as an underground mining operation, which could complement the expected processing of low-grade stockpiles at the Otjikoto mill from 2026 through 2031.
Cash operating costs for the first quarter of 2024 were $642 per gold ounce produced ($561 per ounce gold sold). Cash operating costs per gold ounce produced for the first quarter of 2024 were lower than expected as a result of higher production and a weaker Namibian dollar. Cash operating costs per gold ounce sold for the first quarter of 2024 were lower than the cash operating costs per ounce produced for the first quarter of 2024 as a result of the sale of lower cost inventory produced in the fourth quarter of 2023.
“All-in sustaining costs for the first quarter of 2024 were $958 per gold ounce sold. All-in sustaining costs for the first quarter of 2024 were lower than expected as a result of lower than anticipated cash operating costs, higher than anticipated gold ounces sold and lower than expected sustaining capital expenditures, partially offset by higher gold royalties resulting from a higher-than-expected average realized gold price. The lower sustaining capital expenditures were mainly a result of timing of expenditures and are expected to be incurred later in 2024.
“Capital expenditures for the first quarter of 2024 totalled $14 million, consisting of $11 million for deferred stripping in the Otjikoto pit and $3 million for Wolfshag underground mine development.”
The Otjikoto Mine is expected to produce between 180,000 and 200,000 ounces of gold in 2024 at cash operating costs of between $685 and $745 per ounce and all-in sustaining costs of between $960 and $1,020 per ounce. Gold production at Otjikoto is expected to be relatively consistent throughout 2024.
