| Mineraliseringen er blottet pga. av regulering av Holden, og det er ikke foretatt røskingsarbeider. Mineraliseringen opptrer som en 60 m mektig båndet granittisk gneis (varierer fra fin- til middelskornet) med basiske bånd, og fører svovelkis, magnetitt og spor av kobberkis. Ertsen er anriket i smale bånd og striper i både granittisk gneis (prøve 02) og basiske bånd (prøve 01, 03 og 04). Granat er vanlig og opptrer også i bånd i begge bergartstyper. |
