Within the framework of the international DACH-project "Prehistoric copper production in the eastern and central Alps - technical, social and economic dynamics in space and time" (funded by the Austrian Science Fund FWF, I-1670-G19, the DFG and SNF, 2015 - 2018) traces of Late Bronze Age to Early Iron Age mining activities were systematically prospected and investigated in the fahlore mining district Schwaz-Brixlegg, North-Tyrol, Austria. The aim was to reconstruct the production chain for copper from fahlore and to demonstrate the spatial and chronological development of the prehistoric mining activities in this district. Archaeological excavations were carried out at different places below and above ground comprising a series of fire-set mines, areas with surface depressions (german: "Pingenfelder") and one smelting site. Besides the uncovering, documentation and interpretation of prehistoric structures and findings it was essential to obtain organic materials like wood, charcoal and animal bones for radiocarbon dating and - in the ideal case - timber and/or charcoal for dendrochronological analyses. These investigations could be realised at different spots distributed alongside the mining district of Schwaz-Brixlegg. Parallel to the excavations relevant sectors of the mines were mapped, mine plans were drawn and 3D-models were generated. In addition to the archaeological fieldwork, ore samples from the mining district were systematically collected for mineralogical and geochemical analyses with the aim to characterise the mineral assemblages for subsequent provenience studies. This paper reports on the mining sites investigated within the DACH-project as well as on first results from archaeometric analyses.
