Gem-bearing pegmatite veins, hosted in Cretaceous gabbro and gabbro-norite along the Kolum river, on the eastern flank of the orefield. More than 10 pegmatites host rare metal mineralizations, and two of them at economically significant concentrations. The main vein is 1,200 m long and up to 40 m thick.
