The Redpath Deilmann team from Germany has attracted a lot of attention on its highly successful Nezhinsky Potash Shafts project in Belarus , where it has set a new benchmark in mechanised shaft sinking on two potash freeze shafts
raises and depths . Redpath meets the demands for conventional , box-holing ( up reaming ), down reaming and autonomous reaming .
Groundbreaking milestones in 2021 include the longest raisebore hole in the Northern Hemisphere and all of the Americas at a length of 3,312 ft ( 1,010 m ). The hole at Macassa Mine in Canada was accomplished in two stages with two machines drilling concurrently ; a Redbore 70 underground and a Redbore 90EX on surface . The feat took place merely three months after Redpath broke another record at Niobec Mine in Québec , Canada . The raise at Niobec Mine was completed with the Redbore 90EX raise drill and became the largest ever completed in the Americas and the Northern Hemisphere , and the third biggest globally , at 875 m by 6.3 m diameter . The Redbore series of raisebore machines used for these milestones were designed and manufactured in-house by Redpath in North Bay , Canada .
