Hessengmalmen tilhører ligghorisonten i det østlige malmdrag, Vakkeråsdraget (se FI0012 Boris Gleb). Malmsonen er her foldet ned i en dobbeltfoldet spiss synform. Den kvartsbåndede magnetitt-mineraliseringen (prøve 01) er blottet rett sør for et lite tjern, litt vest for kraftlinje. (Den er noe feilplottet på geologisk kart 1 : 50 000 Høybuktmoen.) Mektigheten er minst 10 m. Det er også kompassutslag over myra på tjernets østside, og en liten blotning av mineralisering i myras nordkant. Om malmmektigheten er sammenhengende under overdekket er den minst 20 m, men sannsynligvis dreier det seg om flere parallelle soner (?). Noe ovenfor i lia er det røsket litt i den foldede mineraliseringens sørflanke. Mektigheten er her omlag 10 m, men pga. dårlig blotning kan det ikke fastslås om det er innblanding av sideberg i sonen. Malmen er Bjørnevannskvalitet, med ca. 30 % Fe magn. Malmarealet er beregnet til 12 500 m2, og Iversen (1986) konkluderer med at det er for små og flisete malmer, samt at de ligger for nær bebyggelsen på Hesseng til å være driftsaktuelle.
