This is a new graphite discovered that was found as a result of the 2013 helicopter geophysics that was measured over Lofototen and Vesterålen. The deposit was sampled late oktober 2013 and found to comprise several up .7m wide massive graphite body close to the sea. A airborne geophysical anomaly can be followed across the penisula for for several km. Ground geophysical measurements show that this anomaly comprise several independent conductors over a profile length of several hundred meters. The area is very overburden and contain very few outcrops. Drilling or trechning would be nessecary to check this deposit accurately.

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

Geological and ore dressing investigations of graphite occurrences in Bø, Sortland, Hadsel and Øksnes municipalities, Vesterålen, Nordland County, Northern Norway 2015-2016.
;Norges geologiske undersøkelse;RAPPORT;NGU-rapport; No.2017.015;70 pages
Abstract:
This report describes 21 graphite occurrences in the Lofoten-Vesterålen area, including reviews of previous graphite investigations, the geological setting and analytical data related to analyses of graphite in the described occurrences. The graphite occurrences are situated in high-grad Archaean metamorphic rocks comprising quartzites, intermediate and mafic gneisses, iron formations, dolomites and graphite schist. This suite of rocks is intruded by a number of igneous complexes, mainly intermediate to acid charnockitic rocks and granites.

Abstract:
Geological and geophysical investigations in Vesterålen were carried out during 2015 and 2016 with additional funds from the Nordland County Administration. A first report (Gautneb, et al., 2017) emphasizes the geological aspects of the graphite prospecting (trenching, sampling, analyses, mineralogy and beneficiation tests). This report describes the results from ground geophysical mapping of graphite mineralisations at five locations in the Vesterålen area. These are: Møkland (UTM 486848 – 7627365), Sommarland (UTM 488080 - 7625780), Kvernfjorddalen (UTM 488445 – 7619975) and Haugsnes (UTM 488600 - 7619375) in Bø municipality and Smines in Øksnes (UTM 498793 – 7639018) municipality.

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.
