The aim of this paper is to provide an in-depth study, including both invasive and non-invasive chemical analyses, and lead isotope analysis, of one of the northernmost Early Neolithic copper flat axeheads in Europe, the Öja axehead from west Sweden. In addition, we present an updated catalogue of the early copper axeheads found in Sweden. Our analyses suggest that the copper used to manufacture the Öja axehead originates from eastern Serbian ore sources, confirming previous studies on other Early Neolithic metal finds from southern Scandinavia. Comparing our results with the current understanding of copper production and circulation across the continent during the 5th and 4th millennium BCE, important new questions emerge concerning early copper mining in south-east Europe and the production and consumption of early copper artefacts in Europe and Scandinavia.
