Bruelv mt,-malm ligger 105 og 115 m.o.h De 2 Bruelv-stollene ligger 10 høydemeter rett under hverandre. Nedre stoll er 19m lang og her er 8m-malmen.Øvre stoll er 70m lang med mt,-impregnasjon og 1m mt,-malm. I mt.-malmen her opptrer svovelkis anriket i cm-tykke bånd (1-3 mm svovelkis-korn i grovkornet magnetitt) Det opptrer også diskordante tynne svovelkis-ganger med noe magnetkis og kobberkis inne i jernmalmen. Bruelv-tonnasjen er liten: Nedre stoll-malm:105 m.o.h.,tykkelse 8m,lengde 50m,dybde 20m. Spes.v. 3,2 (svarer til Fe total=25) som gir 25 600 tonn. Øvre stoll-malm:115 m.o.h. ,tykkelse 1m,lengde 50m,dybde 20m. Spes.v. 3,2 (svarer til Fe total=25) som gir 3 200 tonn. Det er boret 4 hull tilsammen 170m derav 17m i malm ved Bruelv. Boringen viser at malm med 30% Fe total er bare 1m og 2m tykk,mens tykkere malm ofte bare holder ca. 20% Fe total.
