Ore prospecting using peat and humus samples was carried out in Lapland on a nickel critical area. The metals that were enriched in peat most readily were nickel, cobalt and molybdenum, while chromium was enriched in both peat and humus, and copper and lead in humus and rhizomorphous material. Zinc tended to favour the latter material. Geochemical anomalies in organic surficial deposits were also found in places where no mineralised bedrock is currently known, although that may be revealed upon closer examination. In critical areas the distance between transects should be less than 100 m, so that no ores are missed.
