NAHANNI INVESTMENTS CORPORATION

What NAHANNI INVESTMENTS CORPORATION does

Nahanni Investments Corporation, operating as Nahanni Construction, is a Yellowknife-based general contractor specializing in industrial, commercial, and environmental remediation construction in Canada's Arctic and sub-Arctic regions above the 60th parallel. Founded in 1986, the company delivers concrete, civil, mechanical, fabrication, steel erection, electrical/instrumentation, and project management services to mining operators, government agencies, and joint venture partners across the Northwest Territories, Nunavut, Yukon, Alberta, British Columbia, and Ontario. Named clients include Rio Tinto, BHP, De Beers, Equinox Gold, Baffinland Iron Mines, Newmont, and Parsons Inc., and the firm has participated in all five major mining projects developed in Canada's North over the past 20 years.

The company's technical differentiators center on cold-weather execution capability, with documented operations down to -50°C and a proprietary slag cement paste backfill system used to stabilize legacy underground chambers at the Giant Mine remediation project. That capability earned Nahanni the Slag Cement Association Innovation Award in 2020 as the first Canadian recipient. Additional technical capabilities include LIDAR drone mapping for remediation site assessment, mobile and portable concrete batch plant operations, and high-pH solids slurry batching for tunnel construction. The firm operates through two joint ventures — Delta Nahanni Joint Venture (DNV) and Detoncho Nahanni Limited (DCN) — that share risk on large-scale remediation and underground stabilization projects.

Nahanni generates revenue through project-based contracts on a lump-sum or time-and-materials basis, with each engagement custom-scoped and bid individually based on location, complexity, and contract terms. Pricing is not publicly disclosed and the company maintains no standard tier structure. The go-to-market motion is sales-led and relationship-driven, with work acquired through direct business development with major mining companies, competitive bidding on large contracts, and participation in government remediation programs. Long-tenured client relationships — including continuous work at BHP Ekati since 1998 and Rio Tinto's Diavik since 1999 — indicate heavy reliance on repeat engagements within a concentrated northern mining customer base.
