| Forekomsten er blottet på jordene rundt de 3 ytterste husene ved Haugsneset, Det er blottet en 2 meter bred kompakt grafittskifer som kan følges med EM under overdekkning over en distanse på minst 200 meter. I 1952 befarte Henrich Neuman forekomsten han fant at grafittskiferen hadde en bredde på ca. 10 meter. Grafittskiferen er fet og meget rik, kjemiske analyser viser gehalter fra 12 til 33 % grafitt. På østesiden av haugsneset er det noen minere blottninger nede ved sjøen som viser en noe fattigere grafittskifer. Forekomsten må anses som interessant, men opptrer i et svært overbygd området. Forekomstens beliggenhet og strøk viser at grafitt draget fra Sommarland kan følges helt ned til Haugsneset dvs. en avstand på ca. 6 km. Det er estimert at grafitt daget på Haugsneset har tonnasjer og gehalter på 8.4 Mt med 16.2% total karbon. |

| Abstract: | |
| As a part of the MINN project (Minerals in Northern Norway), a helicopter-borne geophysical survey was performed in Lofoten and Vesterålen in 2013. Electromagnetic data from this survey showed up anomalies that may be caused by large graphite mineralisation. With financial support from Nordland County, NGU has performed geophysical and geological follow-up work to 1) confirm the existence of graphite and 2) Briefly evaluate the quantity and quality of graphite structures. The project started in 2015 and the results from the first two years are reported by Gautneb et al. (2017) and Rønning et al. (2017). Follow-up work performed in 2017 is reported in this report. 15 locations have been investigated in total in 2017. The degree of detail in these studies varies from just a few lines of simple electromagnetic measurements (EM31) to electric measurements such as Self Potential (SP), Charged Potential (CP) and Electric Resistivity Traversing (ERT) in combination with Induced Polarisation (IP). In two areas, Sommarland and Haugsnes in Bø municipality, two short core drilling bore holes were made. The selection of follow-up objects was based on both magnetic and electromagnetic data from helicopter-borne measurements. All results from the 2017 work are reported here. Where possible, the volume of graphite is estimated based on the total strike length, the width of individual zones (from drilling, observations and width of EM31 measurements) and an assumed depth extent of 100 m. In these areas, an estimation of graphite tonnage is also given. |

| Abstract: | |
| Several potential graphite occurrences in Vesterålen were selected for follow-up work based on helicopter-borne geophysical data. The purpose for this is to confirm the existence of the graphite and next to briefly evaluate the quality and quantity of the graphite-bearing structures. The goal for the project, which is sponsored by Nordland county administration, is to increase the knowledge of each individual graphite occurrence. By doing so, the interest in graphite prospecting in Northern Norway may increase, effective prospecting can be implemented, and land planning can be developed with appropriate regard for areas with potential for economic graphite. |

| 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: | |
| 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. |
