Comparison of the lead isotope ratios for the axes from Group 3 with the data for the ores from the Slovak Ore Mountains [59].
The lead isotope ratios for the two flat axes found in Denmark are similar to contemporaneous copper artefacts from Northern Italy, indicating that they were most likely made of copper from the Western Alps and Tuscany [68].
