From the NGU ore database:
The Nordaberg prospect lies at the southside of a hill ca. 600m west of the Nordaberg farm. The deposit was discovered in 1885. The Christiania Minekompani worked the deposit in 1914 with 3-4 workers. Ca. 100 m3 of rock was taken out, yielding 20-25 ton of ore containing 4% of MoS2.
Some of the ore was exported, and some was enriched to a concentrate of 363 kg containing 62,5% molybdenite.
In 1915 77 kg concentrate containing 75% MoS2 was produced.
The prospect is a 25 m long, 1,5 m wide and 6-7 m deep trench in a NNE-SSW direction.
The ore was found in 10-20 cm wide, steeply dipping quartz veins in a slaty meta-sandstone.
The norwegian map at norgeskart.no says "Nordagruvene", implying there should be more than one mine. The NGU report only mentions two minor prospects close to the main mine. The relief map suggests prospects ca. 9 m north of the main mine, 65 m north of the main mine, and maybe one 20 m west of the main mine.
