Første gang mutet i 1909. Noen mindre avblotningsgrøfter er utført etter 1910. 1. 76.85 96.40: 15 m lang grunn, gjengrodd avblotningsgrøft uten tipp. Grønnstein, ingen mineralisering. 2. 76.83 96.53: 15 m lang grunn røsk. Utsprengt 2 m3, 30 cm mektig massiv magnetitt-mineralisering med litt sulfid sees (prøve 01 og 02), ellers lite blottet. Resten er hornblendeskifer med kvarts- og pegmatittbånd, med en god del svovelkis-bånd og litt magnetitt-disseminasjon (03) nær jernformasjonen. 2a.25 m sør for 2: 25 m lang gjengrodd avblotningsgrøft uten tipp. 2b.10 m nord for 2: 10 m lang, gjengrodd avblotningsgrøft med 1 m3 tipp. Ingen blotning. 3. 100 m nord for 2b: Blotning med 1 m bred mineralisert sone som består av noen cm-mektige magnetittbånd i amfibolitt. 3a.15 m SØ for 3: 10 m lang avblotningsgrøft, utsprengt 1 m3. Massiv magnetitt-mineralisering sees på tippen. 4. 76.92 96.62: 40 m lang, grunn, delvis gjengrodd avblotningsgrøft. 2 m3 utsprengt. Granittisk gneis helt vest (heng) i grøfta. Under er det finkornet lys amfibolitt med granat, så mørker amfibolitt med noe sovelkis- disseminasjon. Over 10 m mektighet er det stedvis blottet amfibolitt med magnetitt-striper av opptil 30 cm mektighet (04) med litt svovelkis i konkordante bånd og på sprekker.
