Chromite orebodies, the largest being 50 meters long and 2 meters thick, hosted in serpentine and the neighboring mica schists that were intruded by the serpentine. Used to also produce about 1,000 tons a month of dunite rock, mainly for production of refractories, with minor associated chromium production. Minor eclogite rock is also present.
