| Forekomsten ligger rett ovenfor ei lita ur ovenfor gården Surdal. Det er drevet en 3 m lang stoll med 1 m lang dagskjæring med retning 102°. Stollen er 1 m bred og 1,5 m høy. Tippmateriale ligger spredt nedover ura. Stollen er drevet i en finkornet kvarts-feltspat rik gneis som er grantførende. En svak bånding sees på vitra overflate i gneisen som har foliasjon 16°/25°. Sulfidmineraliseringen utgjøres av svak og jevn disseminasjon av magnetkis og pyritt med små mengder magnetitt. Innholdet av økonomiske metaller er ubetydelig. Brattskrenten ovenfor stollen er også dels sterkt rustfarget. |
