Mineraliseringen er avdekket ved UTM 502120 7629520 med en 30m lang og 2.5m dyp nord-øst syd-vestgående røskegrøft (60m3 tipp) som er delvis gjengrodd. Massiv, middelskornig magnetitt med noe epidot (prøve 03 og 04) er blottet over knapt 1.5m mektighet. Om den er mektigere er usikkert. Noe over er det finkornet diorittisk gneis med litt magnetitt- svovelkisdisseminasjon (prøve 01). Stedvis er det rikere magnetitt- svovelkisdisseminasjon (prøve 02). 25m mot nord-nordvest er en 10m lang, grunn og gjengrodd avblotnings-grøft uten blotning. I veikanten ved UTM 502000 7629670 er blottet en ca. 3m mektig finkornet sukkerkornig (kvarts og feltspat) amfibolitt med disseminasjon til semimassiv magnetitt, noe svovelkis og spor av kobberkis (prøve 05).
