| Forekomsten ligger på østsida av en bekkedal vel 1,2 km nord for Korbu gård. Arbeidene består av en 15 m lang, 1-2 m bred og opptil 3 m høy, øst-vest orientert dagskjæring. Den følger en kvarts-karbonat gang med orientering 82°/75°. Gangen ligger i massiv, mørk grønn grønnstein. Kvarts, dels med hulromsfyllinger, dominerer i gangen, mens karbonat danner smalere årer i kvarts. Blyglans, kobberkis og sinkblende opptrer i aggregater og disseminert i gangen. Tippen er spredt nedover brattskråningen mot vest og har et volum på omkring 50 m3. |
