Master Drilling says it is in the process of drilling a world record hole at Northam Platinum’s Zondereinde platinum group metals mine, in the Bushveld Complex of South Africa.
The contractor has its flagship RD8-1500 raisebore rig on site at Zondereinde and is busy drilling the 4.8 m, 1,420 m deep hole at the operation, it said today.
Master Drilling said: “The project doesn’t just beat all previous drilling benchmarks, but also has very stringent accuracy requirement that requires the latest in Measurement While Drilling technology.”
While Master Drilling did not add any additional details in the news post, Northam Platinum said in its full-year results presentation for the year ending June 30, 2019, that planning and preparation for raiseboring the No.3 shaft at the Western Extension project at Zondereinde was in progress. It added, in a presentation last month, that pilot drilling for the raisebore was at 760 m.
Northam is targeting steady state platinum group metal production of 50,000 oz/y from the Western Extension, which it hopes to achieve in its 2025 financial year.
Master Drilling’s RD8 rig has been used at various mine sites across South Africa and is capable of drilling 8.5 m in diameter and over 1,500 m deep, the company said.
