The Prairie Creek Mine is located in traditional Dene territory in Canada’s Northwest Territories. A feasibility study was completed on the mine in September 2017 with robust economics. The Prairie Creek Project consists of the mine and surrounding land and access.

Access to the property is currently by aircraft as there is not an all-season road in place. The property was originally accessed by a winter road that extended  180 km from the mine to the Liard Highway 7. In order to support full-time operation of the mine, NorZinc planned to upgrade the winter road to an all-season access road.

Allnorth was engaged to provide engineering consulting services for the preliminary design of the access road and bridges along the route. Allnorth’s scope of work also included the preparation of a construction strategy and schedule, as well as preparing a Class 4 capital cost estimate and various management plans.

The design accommodates conventional commercial transport traffic, based on the low traffic volumes of up to 20 trucks per day. The design of the road incorporates localized cut and fill construction and the use of local borrow.
