| Mineraliseringen er godt blottet på en liten forhøyning 100 m NØ for restene av ei løe, som ligger i kanten av en grasvoll. Den finkornige kvartsbåndede magnetitt-mineraliseringen (prøve 01) er minst 15 m mektig. Det er veksling i dm-(opptil 1 m) skala mellom jernmalm og finkornig, lys glimmergneis. Jernmalm dominerer mot den nordlige kontakten, mens gneisinnblandingen er større mot sørkontakten. Det finnes også enkelte dm-mektige malmhorisonter i gneisen sør for hovedmalmsonen. Det er ikke blottet amfibolitt i tilknytning til mineraliseringen, som er vanlig ellers i området. |
