This paper studies the functionality of a flint quarry (Cantera de Silex) from Canadon de la Mina Sector, La Maria Archaeological Locality, Santa Cruz Central Plateau, Argentina. The technological characteristics of the remains found there are analyzed. It is examined if the quarry worked only as a source of raw material or if it was used also as a lithic workshop for the first stages in the toolmaking process. The relationship with Casa del Minero 1 site, located at the same sector, is also examined. More generally, this paper intends to add valuable data which will allow to evaluate in the long term the raw material sourcing and the reduction strategies, as well as the strategies for the use of specific spaces such as quarries and the planning of certain activities related to the organization of the lithic technology of the groups that inhabited this region.
