The reason for being of the Castel-Minier's site is at first to produce silver. This activity also pulls the production of metallic by-products as lead and copper. The current state of the excavations does not allow yet to present the foundry in its entirety. It is still partially under the mouline? of the XVIth century. In the high part of the site is a refining place. It is a workshop intended to produce pure silver and to test its quality before it leaves Castel-Minier. According to archives, one ton of pure silver was annually produced. This production requires reduction furnaces which are probably in the low part of the site and which were covered by the slag heap in time. Out of these furnaces was produced the working lead which was then refined to collect the pure silver.
