| Mineraliseringen ligger 2,5 km øst for Trones, på den nordøstlige delen av Tunnsjøåsen. Det er ingen tegn på større skjerpeaktivitet i området. Mineraliseringen er kun 10 cm bred og er blottet i 3 m's lengde. Den består av få mm brede bånd med disseminert pyritt i en båndet amfibolitt. Amfibolitten ser ut til å ligge som en inneslutning i en granodioritt som danner den nordøstlige delen av Tunnsjøåsen. Sørvest for granodioritten dominerer glimmerrik gneis som dels er silimanittførende. |
