| Det har vært et omfattende arbeide ved Olalemmen. Her finnes 18 skjerp, foruten en del grøfter og diamantborhull. Området dekker et areal på 200x300 meter på begge sider av Olaelva. For nermere beskrivelse, se feltrapport for 1992 av J. Blomsterberg, L.A.G. Terol og T. Madsen. Malmprøver: 01: Pyritt i breksjert grafittskifer (gruve E) 02: Båndet malm med lag av py/Qz, po/cpy, po og Qz. 03: Magnetkismalm med kobberkis (gruve F) 04: Båndet kvarts/svovelkismalm (gruve A) 05: Grafittskifer med disseminert sulfid (gruve H) |
