Forekomsten ligger ca. 100 m nord for Bleriken og ca. 110 m øst for lite tjern. Mineraliseringen består av kobberkis-striper i klorittisk grønnskifer. Den ble funnet av Boliden i 1965 og mer inngående undersøkelser ble gjort i 1968. Det ble funnet en rekke tynne striper med kobberkis over en sone opptil 20 m mektig. Det ble sprengt og prøvetatt i den mest lovende del av sonen som var ca. 5 m mektig, men kun spredte tynne striper ble funnet i 0.1-0.7 m lag. Høyeste gehalter i prøvene var bare 1.5 % Cu.
