This mine worked the same vein as Gabe gottes mine. From the 19th century, ore from a large part of the Saint-Jacques mine network was transported to level -40 of Gabe Gottes before being sent to the processing plant. The mineralization of this sector is therefore very comparable to that of Gabe-Gotes.
