The NGU report describes several iron/manganese deposits under this name, all in the area around the Vestpolltind mountain. A total of 1400 tonnes of ore were produced.

Vogt (1916):
"Øksfjord jernmalmfelt har tre hovedforekomster: Storstollgangen, Svartmalmgangen og Høgtindgangene. Høgtindgangene har rikest malm. Ifg. Øhren har Høytindgangene et malmareal på 7500 m2. Fra denne forekomst gis analyser(Fe, Mn, P og S) av stuffer og skeidet malm. En tre tonns prøve fra Svartmalmgangen holdt etter oppredning 34,6% Fe, 8,9% Mn og 0,35%P. Ifg. Sjøgren holder skeidet malm fra Storstollgangen 46,23% Fe og 6,92% Mn. Malm fra Høgtindforekomstene viser 37 - 38% Fe og 6,5% Mn. Slig fra samme forekomst ga 58,7% Fe og 6,7% Mn. Malmen består hovedsaklig av jernglans med endel magnetitt. En del av mangan-innholdet er silikalbundet (granat- rhodonitt).Ved friknusing tapes særlig Mn og en god del Fe. Det synes ikke rasjonelt å anrike så sterkt at en får mer enn 58% Fe+ Mn i konsentratet. For rentabel drift bør en ikke anvende mer enn 1,8 - 2 tonn rå gods til 1 tonn slig. Stykkmalm (håndskeidet) fra Høytindforekomstene bør kunne gi 43 - 47,1 % Fe og 7,5 - 7,6% Mn."

At the NGU coordinates the LIDAR map doesn't show any mining features, but at 68.50929,15.601 there could be an adit.
Magnesioferrite has been reporteted from Vestpollen (Eriksen 2017).
The coordinates are generic for the fjord Vestpollen
