Skjerpet ligger i en liten kløft 20 m fra spissen av en halvøy (øst for Gjeitingvika) som stikker ut mot sydvest. Kløfta gennomskylles under stormer, og det var intet tippmateriale å se. Kløfta er parallell med en forskifring som er orientert 114°/80°N. De eneste tegn på mineralisering var et borehull samt en rødfarging av den gabbroide vertsbergarten. Malmen er sterkt forvitret og inneholder 5-10% molydenglans i aggregater opp til 1 cm's størrelse. Mineraliseringen har form som en 1.5 m lang og opp til 60 cm bred linse eller klump. Reusch (1888) skriver: "etsteds forekom i dioriten en liden smule kobberkis, hvorpå der har været skjerpet". Undertegnede så ikke kobberkis her, så det kan muligens finnes enda et skjerp i området.
