The integration of Byrnecut Offshore into B2Gold’s Otjikoto mine has led to a recovery in development rates at the Wolfshag underground mine, the Canada-based company said in its recently released June quarter results.
Otjikoto produced 31,417 ounces of gold in this quarter of 2022, 2,027 ounces less than expected, as gold production was lower than expected due to a slower-than-expected ramp-up in development at Wolfshag.
The company recently appointed Byrnecut as its new underground mining contractor under a $112 million contract. The agreement covers both development and production, comprising a total of 10 km of development and a total material movement of 3.2 Mt.
Wolfshag’s underground fleet is sourced primarily from Sandvik Mining & Rock Solutions and currently consists of one DC DD422i jumbo, one DD422i jumbo, two LH517i loaders, three TH551 trucks and one DL432i production drill.
B2Gold said development rates at the Wolfshag underground mine have recovered over the past three months, with development ore now expected in the September quarter and stope ore production commencing in the September quarter. december.
“Due to this change in the ore production schedule, the 2022 annual production range for Otjikoto has been revised to between 165,000 and 175,000 ounces of gold (the original range was between 175,000 and 185,000 ounces of gold). gold),” the company said.
As expected, compared to the June 2021 quarter, gold production increased by 17% due to significant waste stripping operations at the Wolfshag and Otjikoto pits during the first half of 2021.
The initial underground mineral reserve estimate for the deep extension of the Wolfshag deposit includes 210,000 oz of gold in 1.2 Mt of ore at 5.57 g/t Au.
