Holmtjärnsgruvan


Found 1924 during an exploration programme and part of the outcrop was extensively weathered. One sample gave 1152 ppm Au and stories tell that they mined a small portion (<1kton) with some hundred ppm.

Thought as the "real" beginning of the Boliden Company.

Later mined by Boliden Co. 1984 - 1992, main metals produced Cu, Zn, Pb, Au and Ag.
