Det er ikke utført røskearbeider på mineraliseringa, som ble funnet i 1890 årene. Ved UTM 493520 7635500 løper ei magnetitt- ilmenittdisseminert gabbrolinse (60 x 20m) mot sørvest. Den er middelskornig, foliert og inneholder noe svovelkis (prøve 01 og 02). Ved UTM 493670 7635350 er det blottet samme type mineralisering i en kolle (prøve 03).

Abstract:
Oppramsing av hele landets jern-titanforekomster, hvorav 15 trekkes fram som de største. Hver forekomst beskrives ut fra befaring med geologiske og dels kjemiske data. Oppredningsresultater presenteres også. Oppramsing- en går fra Hedmark til Finnmark i nord.
