What Redpath Inc. does

Redpath Mining Inc. is a privately held, full-service global underground mining contractor founded in 1962 by Jim Redpath and headquartered in North Bay, Ontario, Canada. The company provides mine development, shaft sinking, raiseboring, mechanized raise mining, underground construction, mechanical excavation (TBM, road headers, continuous miners), production drilling, mass excavation, production mining, and engineering and technical services to enterprise mining operators across more than a dozen countries spanning North America, South America, Australia, Asia, Africa, and Europe. Notable clients include Rio Tinto (Oyu Tolgoi Mine in Mongolia), PT Freeport Indonesia (Grasberg Block Cave, 40-year relationship), Vale (Voisey's Bay and Totten), Xstrata Copper (Kidd Creek), Anglo American (Grosvenor), Goldcorp (Musselwhite), Ivanhoe Mines, and Mopani Copper Mines. As of 2024–2025 the company reports roughly 10,000 employees, 108 active projects, 81 sites, and 63 clients.

The company's technical differentiation rests on specialized equipment designed, fabricated, and maintained in-house — most notably a mechanized raise climbing fleet operated since 1975 under patented designs, and the proprietary Redbore family of raisebore drills (Redbore 40 through Redbore 100). Redpath installed the world's largest friction hoist (6.75m diameter) at Oyu Tolgoi, sunk Shaft 2 to a record 124,248 m³ of rock removed, drilled the longest raisebore hole in Australia (844.7m x 4.5m at Cadia using the Redbore 100), executed the deepest cage-equipped shaft sunk with a raisebore in Zambia in a single pass (1,892m at Mindola Deeps), and reached mechanized raise depths of 2,743m below surface at Kidd Creek. In-house repair and training facilities at North Bay support the equipment fleet and workforce development. Subsidiaries include Redpath Australia Pty Ltd, Redpath Canada Limited, Redpath Raiseboring Limited, Redpath Deilmann GmbH (shaft sinking in Europe, formerly Deilmann-Haniel), PT Redpath Indonesia, Redpath Mongolia LLC, Redpath Mining South Africa, Redpath USA Corporation, and entities acquired via the 2024 RUC Mining Contractors deal (TuranIndustrial, PT RUC Indonesia, Incycle Shotcrete). Joint ventures include Dayan Contract Mining LLC (with Hasu Megawatt) for Oyu Tolgoi and the Innu Inuit Redpath Limited Partnership for Voisey's Bay.

Redpath's business model is project-based B2B contracting: revenue is earned from long-cycle underground mining contracts negotiated directly with mining operators on a project-by-project basis, with scope, duration, and pricing tailored to each engagement. The go-to-market motion is direct enterprise field sales, supported by regional headquarters in North Bay, Brisbane, Johannesburg, Ulaanbaatar, Jakarta, Sparks (Nevada), and Dortmund, plus operational offices in Perth, Kalgoorlie, Sudbury, Rouyn-Noranda, Tembagapura, Gaborone, Kitwe, and South Jordan. The firm has historically been founder-controlled and family-influenced; founder Jim Redpath died on August 2, 2025. The company owns no publicly disclosed investors, has not raised institutional capital, and publishes limited operating metrics (revenue, margin) beyond employee count and project totals. The 2024 acquisition of RUC Mining roughly doubled Australian capacity and added Central Asian exposure, marking the most significant inorganic expansion in the company's recent history.
