| A minor ditch on top of the of the small hill range along the road between Langdalen and Øytjern, difficult to locate in dense, young pinewoods. The ditch is 1H1m by 0.5m deep. The mineralization consists of medium rich pyrite impregnation (<5vol%) of 1-2mm grains in quartz rich rock containing some biotite and amphibole. The mineralized zone is about 0.5m thick, but with very limited extent. |
