This study is focused on the E l M ilagro mine ( A sturias, S pain) and is part of a large‐scale effort on the measurement of the lead isotopic composition of S panish copper ores from prehistoric mines in the provinces of A sturias and L eón, from which no data were available until recently. Lead isotopic values are compared to the published lead data from the E l A ramo mine in the same region. The results show that both mines have a very similar lead isotopic composition, apart from some highly radiogenic samples in the E l M ilagro mine, which are clearly different from those previously reported for the I berian P eninsula.
