Njallavarto består av et stort og 7 mindre skjerp. Hovedskjerpet og et mindre skjerp er en del av en antiklinal folding. Skjerpene er inndelt i to parallellforskjøvne belter med strøk 15-20°. Her er tre forskjellige malmtyper: 1: Båndet malm - svovelkis er klart dominerende, kornstr. < 3 mm. 2: Massiv, grovkornet, strukturløs malm med cpy, py, pyrrh, mgt og sph. 3: Disseminert py og cpy. Kornene er jevnt fordelt. Type 2 er mest utbredt. Prøvene fordeler seg slik: 96869: prøve av type 1. NO0328.02 96955: prøve av type 2. NO0328.03 96866: prøve av type 3. NO0328.01
