Mineraliseringen er blottet på nordsiden av en liten knaus, knapt 600 m nord for Hirsajavri. Her er det over en øst-vestlig bredde, sann mektighet ca. 25 m, flere horisonter av finkornig kvartsbåndet magnetitt-mineralisering (prøve 01) av mektighet fra 0.5 til 3 - 4 m i båndet amfibolitt. Jernmalmen er stedvis rusten, og granat er anriket i mm-cm-bånd. Malmsonen fortsetter NV-over til FI0300 Cabbalanjasoaivi, og østover før den bøyer nordover til FI0302 Småvatnelva.
