A scheme for INAA of native copper, which permits the determination of 22–24 elements is proposed. The possible error source in INAA of native copper and other types of more or less pure copper are evaluated quantitatively. The accuracy and precision of the analyses are tested by comparison with NIST-SRM's. The applicability of the proposed method for archaeometric investigations is demonstrated by the analysis of two samples of native copper and two eneolithic archaeological artifacts from Bulgaria.
