| 30m over (i høyde) traktorveien er det utsprengt ca. 30m3 i en skjæring i en skrent i en ca. 1m mektig mineralisering. Det er en 0.5m mektig massiv magnet- svovel- kobberkismineralisering (prøve 02 og 06). De resterende 0.5m er finkornet semimassiv magnet- svovel- kobberkis med spor av molybdenglans i finkornet amfibolitt (prøve 01, 03 og 05). Sulfider er også mobilisert på sprekker og stikk. Sideberg er finkornet amfibolitt med litt svovelkisdisseminasjon (prøve 04 fra heng). |
