Why is mineral development difficult in Nunavut?

Mineral development in Nunavut is primarily hindered by high production costs and significant transportation difficulties.1

Furthermore, the region's environment presents substantial engineering challenges due to the presence of permafrost. The frozen ground complicates mining activities and infrastructure development, as the delicate thermal equilibrium of the soil must be managed to prevent surface subsidence and structural instability. Because permafrost causes poor drainage and is susceptible to frost action—which can destroy structures through frost heaving and loss of bearing strength—any resource extraction project requires extensive planning and specialized engineering to maintain stable foundations.23
