The 2006 campaign looked at two areas. In the knapping area of zone A3 in mine 1 of Defensola A, investigations documented an accumulation of lithic material which was presumably part of the upper layer of debitage which contained numerous utensils, burins and scrapers. The excavation also examined a new earth surface (interpretable as earth from the outside dumped at a moment when mining activity was interrupted), which appeared in the squares of the right centre and side of the knapping floor. The roof of this unit was formed by an earthy brown surface, from which a few silica elements emerged, resting on a layer of whitish gravel, perhaps relating to a previous extractive phase.
The removal of the earth layer revealed a rich surface of lithic finds of all types and size.
