Øvre Kleven magnetittmalm (190-350 m.o.h.) Nederst i sørvest er 2 malmlag ca. 2m tykke. 200m videre nordøstover inneholder amfibolitten en 3-4m og en 0.3m tykk magnetittmalm. 40m øst for stollinngangen (nivå 245) opptrer god 4-7m magnetittmalm. Dette midterste hovedmalmlag er stort sett 6-7m tykt i en strøklengde på 350m nordøstover. I nivå 240 går en 260m lang stoll langs malmen med synk oppover 130m og 240m innover stollen. 3 stk mindre etablerte dagbrudd ligger i nivå 275, 295 og 315. Gjenværende malm er: Øvre Kleven 260-350 m.o.h. tykkelse 6m, lengde 350m, dyp 50m med spes.v.3.2 gir 336.000tonn. Øvre Kleven 190-260 m.o.h. tykkelse 2m, lengde 240m, dyp 50m med spes.v.3.2 gir 76.000tonn. Dette gir et totalvolum på 412.800 tonn. I Øvre Kleven er det boret 7 hull tilsammen 291.8 meter, hvorav 107.9 meter i malm. Det er analysert 2 håndstykker fra dagbruddet nivå 275: Fe tot. Fe magn.
