This short campaign on the flint-mining site of Cruci, situated in the territory of Peschici (FG), was undertaken in order to check the hypothesis formed during the 2011 excavations regarding the working of flint in the proximity of the mine site.

Work concentrated on one of the areas with the largest scatters (identified as CR4), situated on the upper part of the slope, at the base of which mine n. 2 opened (investigated by Rellini in the 1930s). A vast amount of worked flint lay over this surface (of about 250 m2), both in the form of un-retouched flakes and nuclei and retouched artefacts, in particular Campignani tranchets, but mainly very high quality burins. The latter are usually a marginal presence in Eneolithic complexes on the Gargano peninsula.

The 2011 excavation, which aimed to identify the level from which these artefacts came, had uncovered a brown layer with lithic industry in situ (US3) below a layer of mine gravel, also in primary deposition (US2). Continuation of work in this trench was intended to explore this context down to the bedrock. It was constituted by a brown lumpy sediment with some gravel spread throughout. Probably dumped material, it contained very little lithic industry none of which diagnostic. The only element of some interest was a charcoal fragment, whose radiocarbon dating, will provide a terminus post quem for the overlying mine gravel. The bedrock was exposed after between 10 and 15 cm of US3 had been removed. Its surface was covered by a calcareous crust a few centimetres thick, with some slight terrigenous infiltrations (US4), containing occasional fragments of worked flint. The part directly in contact with the bedrock was very concretionary and so was only partially removed.

At this stage in the excavation, the archaeological horizon, which produced the vast amount of worked flint present on the surface around the trench is still unknown. It should probably to be sought further up the hill slope, which incidentally showed an interesting change in morphology a few metres away. The surface around the trench produced other worked flint, in particular burins, but also tranchets and tranchet flakes.
