Langli-malmen har de beste blotninger ved vestenden av Langlimyra og 300 m VNV-over, bl.a. med røsker. Her sees innenfor en 60m bredde 3-5 malmlag slik (M=magnetittmalm, H=hematittmalm): I vest i øst ----------------------------------------------- 2,2m M 2-3m MH 2m H 0,5m H - 2,5-2m M 2-6m M 2,5m M 1-2m M 1-3m M 2,5m M 1-4m M 1-4-5m M Den vestligste 1,5 km lange delen av Langlimalmen ligger 350-450m SV for Bergedalsmalmen. I østre deler av Langli-horisonten opptrer delvis fattig mt.-hem.-impregnert glimmerskifer.
