Thank you, Madam Chair. So at this point in time we're working with the Tlicho government to do technical refresh study, and a part of that is determining the most optimal route. So accordingly the -- depending on the route, the length, the terrain, a number of different factors will come into play when we develop cost estimates. So unfortunately we would not have a cost estimate at this point in time. Once we do the updated routing, we'll have to go back and develop that updated cost estimate, which would support the federal funding application. Thank you, Madam Chair.
