3 Former VMS Mines
Former Mines
Fadalsgruvene opened in 1660, there was sporadic production in 5 periods
ending in 1788. Little is known about this mine. Vingelen gruve discovered in about 1800. About 30 000 t of ore was produced in several periods between c. 1800 and 1920 estimated at 1.3 % Cu. The deposit is not
delimited. Fredrik IV opened in 1707 and operated sporadically until 1908. NGU sampling of the old dumps showed up to 10% Cu with silver values up to 30 gpt and gold values up
to 4.7 gpt.
Significant Mineral Occurrences
Sivilangen discovered in 1917 exploration in 1953, 1974-75 and 1990-91. a non-
43-101 compliant estimate suggested that it contains about 0.4 Mt with 0.69% Cu and
4.31 % Zn. The deposit is open to depth. Vardtjonna a large mineralized zone at least 1.2 km long and 130m wide. There are eight smaller showings in the area, of which five are associated with a major
alteration zone of quartz-sericite schist Nedre Vardtjonbekken a small showing sampled by NGU in 1989. Two analyses of the massive ore yielded 0.5, 1.3% Cu, 1.5,9.1% Zn, 0.1-0.3% Pb, 26, 27 gpt
Ag and 9.6, 11.0 gpt Au.
Flatskarvasen Sampling of the old dumps by NGU showed up to 4.2% Cu with
gold values up to 4.8 gpt.
