Excavation of the Mine

The excavation of the prehistoric flint mine of Casa Montero was very challenging. The M-50 motorway construction schedule meant the time available to inspect such a large site, with its many structures, was very short. Further, innovations were needed in the sampling and excavation methodologies used at this unique site.

Work in the area of the site affected by construction of the motorway was completed in just three field seasons covering a period of 24 months. This involved the excavation of 338 shafts (270 completely). About 2229 m³ of earth were moved in this work, and some 66 tonnes of lithic material extracted from the shafts. These figures highlight the size of this mine and the huge amount of material that had to be processed.
