Lupin Mine is located near Contwoyto Lake. The lake is also the terminus of the Tibbitt to Contwoyto Winter Road from Tibbitt Lake in the Northwest Territories, Nunavut's only currently existing road access to the rest of Canada. In 2005, there was a proposal put forward to extend the winter road to a possible port at Bathurst Inlet.
