| Rett på vestsida av en sidevei til bomveien opp fra Tveitgrendi går det inn en dagskjæring som er 7 m lang, 1-1,5 m bred og opptil 3 m høy i sørvest. Skjæringa har retning 275º. Dons (1963) beskriver andre skjerp fra det samme området som alle skal ha vært drevet i 1887. Finkornet, relativt massiv, grågrønn amfibolitt dominerer i skjerpet. Sentral i vestveggen finnes en 4-5 cm bred kvartsåre med noe kobberkis og litt pyritt. Den har retning 87º/75º. Amfibolitten er tilsynelatende ikke omvandlet omkring åra. Ubetydelig forekomst. |

| Vel 50 m øst for hovedskjerpet finnes to mindre, gjengrodde skjerp i den samme amfibolitten. Det ene er ei lita grop hvor en 10 cm bred umineralisert kvartsgang er blotta. |
