| Det er skogsbilvei helt fram til SV-enden av forekomsten. Videre østover ligger forekomsten i nordsida av den såkalte Kongestien (eldste historisk kjente vei i Dunderlandsdalen). Det er jevnt bra med gode blotninger i forekomsten, bl.a. en 75m lang røskegrøft som riktignok går i strøkretningen. Forekomsten er beregnet langs 120m ved hjelp av 4 profiler i M 1:1000. Dette gir 457 000 tonn malm. Forekomsten består av 3 malmtyper: 1) Finkornet karbonatførende kvarts-magnetittmalm. 2) Finkornet cummingtonittførende magnetitt-hornblendeskifer. 3) Sterkt magnetittimpregnert karbonatglimmerskifer. 2 analyser fra Eiteråforekomsten er utført ved Norsk Jernverks lab. 1971: Fe-total Fe-magn.
