Redpath reported it raisebored an 875.1-m pilot hole in Québec, Canada. A Redboer 90EX raisedrill drilled the “record-breaking” hole, which varied by only 0.03% over the length of the hole and was completed ahead of schedule, the company reported.
The previous record for the Americas was 845 m. That hole was also completed by Redpath, and the record stood for more than a decade, the company reported.
Redpath is raiseboring a 1,009-m pilot hole elsewhere in Canada.
