The choice between the different transport scenarios was made on many criteria. The scenario for Saint-Fulgence was superior to both routes to Forestville in its technical, economic and natural environments and equally advantageous in terms of the human environment. In addition, on the most advantageous route of Forestville, the last 89 kilometers are asphalted and normed. It is therefore impossible to circulate our trucks of concentrate. To this must be added to the road options, the comparison of port options. In both cases, warehouses, conveyors, dock, loaders and other industrial facilities are to be built. In the Sainte-Rose scenario, we need to create a new site, directly in deep water. The port of Forestville is existing, but it would have been necessary to build a 3 kilometers long pier in the St. Lawrence to reach the deep water. (For obvious environmental reasons, we refused to consider dredging over such a distance.) The Sainte-Rose site was therefore judged to have less impact.
