This prospect was found in 2013 from NGUs new airborne geophysics. The despist is visible as a several layers of graphite that can be followed from the shore and north wards. Few meters east of the cemetary some old pitting can be found and a compact graphite ore body of 2 meters with are exposed. The graphite ore is coares and flaky, and grades up to 36% of graphitic carbon is found. Profiles with portable EM equipment, shown that there are several good conductors under overburden a long the beach in this area. Several og these anomalies can be followed along strike for a distance of 300 meter. The width of the mineralized area is about 100 meters.

Abstract:
NGU conducted an ariborne geophysical survey in Langøya area in July - August 2013 as part of the MINN-project. This report describes and documents the acquisition, processing and visualization of recorded datasets. The geophysical survey results reported herein are 5650 line km, covering an area of 1050 km2

The graphite occurrences of northern Norway, a review of geology, geophysics and resources
;ARTIKKEL;Minerals; No.7(10);24 s. pages
Abstract:
Artikkel i Minerals 2020 nr. 7 vol. 10. Abstract: There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources from 28 occurrences. We use a combination of airborne and ground geophysics to estimate the dimensions of the mineralized areas, and, combined with sampling and analysis of the graphite contents, this gives us inferred resources for almost all the occurrences. The average TC (total carbon) content is 11.6%, and the average size is 9.3 Mt or 0.8 Mt of contained graphite. We demonstrate that the Norwegian graphite occurrences have grades and tonnages of the same order of magnitude as reported elsewhere. The graphite-bearing rocks occur in a sequence that encompasses carbonates, meta-arenites, acid to intermediate pyroxene gneisses, and banded iron formations metamorphosed into the granulite facies. Available radiometric dating shows that the graphite-bearing rocks are predated by Archean gneisses and postdated by Proterozoic intrusions of granitic to intermediate compositions.
