Photo: ØT
Old mine run on chalcopyrite-pyrrhotite-sphalerite ore. In contact with metamorphic garnet-amphibole-epidote skarn.
In 1870 they started test-mining on sphalerite at Glomsrudkollen on Øståsen in southern Modum. Four or five men started this year the mining, and during one month they got 110 tons of black ore, but despite that they stopped the mining.
In 1899 a Belgian company started test-mining with 20 men. They mined 286 tons ore with 30-50% zinc, the mining ended by the end of the year. In 1907 once again they started mining, and the year after 56 persons worked in the mines.
In 1909 the rights was given to a German company.
The mining at Glomsrudkollen ended in 1921 and in 1928 the mines where sold to an other company, but the mining never started again.
