Kleiva finkornet fosfor-rik mt.-malm og hem.malm ligger 1 km sør for Oscarsborg, Narvik by. Ved Ytre Kleiva jernbaneskjæring er malmen 6 m tykk. 170 m.o.h.er en 55 m lang stoll. 3 malmprøver fra Kleivafeltet 110 m.o.h. fra en 7 m tykk malm (analysert ved Norsk Jernverk lab 1978), gir følgende resultater: Fe-total Fe-magn. MnO TiO2 P S ------------------------------------------------------------ 33,3 23,1 0,10 0,25 1,320 0,042 23,4 12,4 0,14 0,23 1,468 0,115 29,1 3,2 0,16 0,35 0,252 0,030 Sistnevnte prøve er særlig hematitt-rik og vanlig lav i apatitt. Hematitt er ganske vanlig i denne 7m-malmen. Tidligere rapporter fra Kleivafeltet er av E. Mørtsell (1908) og I Keuthen (1911). Rapporten av Mørtsell nevner to analyser av Kleiva-malm: a) Narvik kjemiske Burå 1908: 33,0 % Fe-tot., 0,40 % MnO, 1,14 % P, 0,07 % S, 0,20 % TiO2, 35,74 % SiO2, 8,26 Al2O3, 4,53 % CaO, 2,05 % MgO og 0,40 % CO2. b) Svensk analyse 1908: 33,0 % Fe-tot., 1,34 % P, 0,12 % S og 0,12 % TiO2. 22 prøver av Kleiva-malm ble analysert med verdier 17,5-31,0 % Fe-total og aritmetisk middel 25,2 % Fe-total. Keuthens rapport med en tenkt 30 m tykk og 940 m lang malm er alt for optimistisk. En 7 m tykk og 600 m lang malm er mere realistisk. I Kleiva-feltet kan man vente 1,2 mill.t. malm: Tykkelse Lengde Dyp Tonnasje (sp.v.3,0) -------------------------------------------------------------- 7 m 600 m 100 m 1,26 mill.tonn
