Redpath completes largest bored raise by volume in the Americas February 16, 2021 Topics Last week, the Redpath Group reached a major milestone, as the company completed an 875-metre-long by 6.3-metre-diameter raise at the privately held Niobec mine in Quebec. The raise is the largest by volume ever completed in the Americas and in the Northern Hemisphere and is the third biggest globally. The Redbore 90EX raise drill, manufactured by Redpath in North Bay, was chosen as the most appropriate unit to complete this project. The remarkable achievement was a team effort that started in 2019, when Niobec approached Redpath. “Having worked together previously, Redpath’s project team understood Niobec’s needs for achieving a fully integrated process, ensuring the lowest possible end cost, coupled with the highest standards of safety and productivity. The engineering and construction teams of our two companies worked in partnership to achieve this goal. The project finished safely and ahead of schedule,” Johan Davel, general manager of Redpath Raiseboring, said in a release.
