Røylimalmen ligger 60-70m og 140-180m nord for østenden av Hullbekkmalmen. Det vil si at det er et 1-2m tykt og 300m langt malmlag i sør kalt Søndre Røyli (ikke malmblotninger) og et 1-5m tykt og 530m langt malmlag i nord kalt Nordre Røyli. Disse to malmlag har sine utkilinger mot vest ca. 160m øst for Fosshaug gårdsruin. Nordre Røyli-malmlaget som går i Røylidalen - Røylia er hovedmalmen med de beste blotninger. Malmen kan der godt studeres ved polygondraget mellom pkt. 613 i VNV og pkt. 606 i ØSØ. Malmen har hematitt i ligg og magnetitt i heng. Ved punkt 608 og 613 er det ren magnetittmalm (1 m). Dersom vi regner nordre lag: 500m lang, 2m gj.snittstykkelse, 50m dyp og sp.v. 3,4, utgjør dette 170 000 tonn. |

Abstract: | |
I forbindelse med påtenkt gruvedrift under Ørtvann kan det bli aktuelt å tørrlegge vannet ved tunnel til Ranaelv. GM fikk i oppdrag å fastlegge bunnavleiringenes mektighet langs en rekke profiler som dekker en betydelig del av vannet. Målingene ble utført etter vanlig seismisk refraksjonsmetode. Det ble oppnådd gode seismogrammer. De ga grunnlag for stort sett entydige tolkninger som i rapporten er vist i grunnprofiler. |
