Mary River Iron Ore Project

The Mary River iron ore deposit is located 160 km south of Pond Inlet, Baffin Island, NU. Nuna has long been a partner of Baffinland Iron Mines as the Company has developed the Mary River Project. From Nuna’s earliest activities on site in 2007, which included the tote road upgrade and initial bulk sample to current activities including a variety of heavy civil construction activities and site services, Nuna has worked closely with Baffinland and has made Inuit training and employment a high priority.
