Rupsiforekomsten er tolket å korrelere med Hankabakken/Palmbergnivået, og er den nordvestligste forekomsten i Sulitjelma. Mineraliseringen er en stratabundet impregnasjonstype i breksjert kloritt/biotittskifer. En malmskjæring viser høye gehalter over 7 m mektighet (2.3 % Cu og 1.5 % Zn), men forekomsten er ikke malmberegnet. To foldefaser har dannet en liggende elongert antiform med malmanrikning i ombøyningssonen. Borkjerner fra 14 borhull fra Rupsiforekomsten ligger på kjernelager i Sulitjelma, delvis lagret som 10 cm kjerne fra hver bormeter. Stien, R. 1993. Ved befaring i 1994 ble to borplasser funnet i det angitte området. På begge steder ligger det igjen store mengder borkjerner, men det finnes ikke prøver med rik mineralisering, bare rusten kvarts-serisitt-glimmerskifer. Prøve ble tatt av det mest rustne materiale. Furuhaug, L. 1994. Utfra rapport av Bugge et al. 1978 er det estimert en ressurs på 4.2 Mt med 1.1 % Cu på tre nivåer i Rupsi.

Abstract:
The eugeoclinal rocks of the Sulitjelma region occup a large depression in the Norwegian Caldonodrd betwwen the Nasafjell tectonic window of Precambrian rocks in the south and the Tysfjord window in the north. The age of the rocks is thought to be Cambro-Silurian. The regionl metamophism is mainly in greenschist facies in the lower units, amphibolite facies in the Gasak Nappe and greenschist to amphibolite facies in the Fauske Nappe. Some of the largest sulphide deposits in Norway are located near Sulitjelma. The different types of mineralizations occurring in the region are briefly described.

Mineraliseringsindikasjoner ble funnet i 1983 under et bekkesedimentprogram i USB-regi. I 1984 ble oppfølgingsarbeidet (detaljgeologi og -geokjemi) konsentrert omkring skjærsonen ved Sørskardvatnet. Scheelittmineraliseringene opptrer i en ca. 25km lang og 150-300m bred "skjærsone", hvor 3 mineraliseringstyper forekommer: 1) Fint disseminert sceelitt i biotitt-karbonatskifer. 2) Grovkornet scheelitt i epigenetiske turmalin-boudiner. 3) Svakt mineralisert hydrothermale kvartsganger. "Skjærsonen" finnes mellom prekambriske sedimenter og eokambriske til nedre paleozoiske dekkeenheter. Den er begrenset av skyvesoner. Bergartene består av 0.5-25m mektige enheter med biotittskifre, biotitt-magnetkisskifre, biotitt-karbonatskifre, kvarts-zoisitt- og turmalinpegmatitter, samt enkelte store og mange små metagabbrolegemer (amfibolitter). Scheelitt i biotitt-karbonatskifer er den mest utbredte mineraliseringstypen i området. Den er stratabundet - finfordelt scheelitt (0.1-2mm) finnes i stratiforme, mm-tynne lag i skiferen. Gehalten er meget lav, med høyeste analyseverdier omkring 160ppm W, men sannsynlig tonnasje er stor: den mineraliserte skiferens mektighet er 12-15m over 25km lengde. Epigenetiske turmalin-boudiner er den mineraliseringstype som fører de høyeste W-gehalter, opptil 0.1%. De finnes som diskordante boudiner på opptil 30x70cm , med cm-store hulromsfyllinger av scheelitt. Hydrothermale kvartsganger finnes innenfor "skjærsonen" i form av cm-dm mektige ganger med meget svak mineralisering av scheelitt og små mengder magnetkis og litt kobberkis. Disse kvartsgangene er lokalt gull-anomale, høyeste analyseverdi er 165ppb Au.

Feltundersøkelser av wolframmineraliseringer ved Sørskardvatnet, Valnesfjord, Nordland.
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.85.048;26 pages
Abstract:
Ved Sørskardvatnet er det påvist svake wolfram-mineraliseringer (scheelitt) i en kvarts/karbonat-skifer, i kvartspegmatitter og i turmalinpegmatitter. Disse bergarter opptrer innenfor en 100 - 200 m mektig og flere mil lang, sterkt deformert sone mellom 2 kaledonske skyvedekke-enheter. En wolframholdig bergartsprøve fra biotitt/karbonat-skiferen inneholder et forhøyet gullinnhold (22 ppb), mens en pegmatittprøve inneholder 165 ppb.

Abstract:
Med økonomisk støtte fra NGUs USB-prosjekt har en gruppe fra København Universitet under ledelse av lektor Henrik Stendal, utført metallogenetiske undersøkelser av W-mineraliseringer i Salten-regionen. I øyeblikket pågår 3 hovedfagsarbeider (Kbh. Univ.) og et doktorgradsarbeide (NTH). Salten-regionen er en W-provins med en rekke lavgehaltige scheelittmineral- iseringer av sannsynlig exhalativ type i karbonatholdige glimmerskifre, samt på kvartsganger/pegmatitter og i skarnbergarter i de samme områder. Selv om skarn-mineraliseringene kan være relativt rike er det ikke påvist gode indikasjoner på større, økonomisk lovende forekomster. I forbindelse med W-undersøkelsene er det ved tungmineralvasking i elver og bekker påvist anomale delområder på elementer som Au, Ba, Hf og U-Th.

Mineraliseringen ved Villumselv er antatt å være fortsettelsen av Jenny-sonen vestover fra Furuhaugen. Området ble oppboret med ca. 5 hull i 1942 på bakgrunn av geofysiske målinger. Svak impregnasjon av svovelkis og kobberkis ble påvist, men analysedata er ikke funnet. Pkt. 9 er antatt å ha samme analyser som i nærliggende. Området antas ikke å være interessant for ytterligere undersøkelser. Stien, R. 1993. Forkomsten ble funnet på et noe annet sted enn oppgitt fra R. Stien ved prøvetaking i 1994. Forekomsten er en liten vannfylt synk i en myrkant med tipp < 10 m3. Staw, J. 1994.

Abstract:
Det var stilt som oppgave å undersøke nordre del av den malmførende horisont i Baldoaivvesynklinalen i strøket Villumelv - Storforsdalen. Undersøkelsene skulle foregå i områdene mellom feltet som i 1941 ble målt ved Furuhaugen gr. - Villumelv (GM Rapport nr. 26) og feltet som i 1967 ble målt syd for Storforsdalen, (NGU Rapport nr. 770). Det undersøkte området er ca. 15 km langt og har et areal på 32 km2. Det ble utført el.magn.kond.målinger (Turam) på vanlig måte. Ved målingene ble det påvist en rekke soner av varierende ledningsevne. Sonene ligger tildels grunt nær utgåendet av den malmførende horisont, tildels ligger de dypt og langt innenfor utgåendet av den malmførende horisont. I rapporten er det fremlagt forslag til plassering av borhull.

Kochhammerens mineralisering er antatt å være fortsettelsen av Jenny-sonen fra Furuhaugen. En prøvestoll er drevet inn, trolig i samme tidsrom som det var prøvedrift på Furuhaugen. Stien, R. 1993. Ved prøvetaking i 1994 ble forekomsten funnet på et noe annet sted enn Stiens plassering. Ialt tre stoller er drevet inn i hammeren i forskjellige nivå, og flere hundre m3 med tippmateriale ligger under hammeren (NO0338.01). Flere cm store svovelkiskrystaller. En dagskjæring i en kvartsgang på myra ca. 100 m nord for hammeren har druserom med fine bergkrystaller samt svovel- og kopperkismineralisering. Furuhaug, L. 1994.

Mineraliseringen i Helsingborg består av en kopperkisførende kvartsgang. Kun en kort periode med prøvedrift. Ingen dokumentasjon funnet. Stien, R. 1993. Gruven er øverst drevet i en ca. 100 m lang dagskjæring med slakt, vestlig fall (NO0373.02). Ca. 50 m lenger ned (øst for dagskjæringen) er det en stollinngang med en god del materiale utenfor (NO0373.01). Furuhaug, L. 1994.

Abstract:
The eugeoclinal rocks of the Sulitjelma region occup a large depression in the Norwegian Caldonodrd betwwen the Nasafjell tectonic window of Precambrian rocks in the south and the Tysfjord window in the north. The age of the rocks is thought to be Cambro-Silurian. The regionl metamophism is mainly in greenschist facies in the lower units, amphibolite facies in the Gasak Nappe and greenschist to amphibolite facies in the Fauske Nappe. Some of the largest sulphide deposits in Norway are located near Sulitjelma. The different types of mineralizations occurring in the region are briefly described.

Some guide-lines to ore in the Sulitjelma ore field
;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU; No.360;s.235-236 pages
Abstract:
The Sulitjelma Field occupies an area of 2500 km² of the Norwegian Caldonides near the border to Sweden north of the Arctic Circle. In the central part, an area of 500 km² is mineralized with sulphide, stratabound within a metavolcanic unit; the Sulitjelma Amphibolite. Within an area of 100 km² - the Sulitjelma ore field - there occur several ore deposits under variable stages of operation - mined out, being mined at present, planned mining, areas showing potential for deep ore prospecting and exploration. Around 20 ores are known in the range 0.2-5.0 M.t, while the total tonnage so far recorded is 30 M.t. with an average of 1.85 % Cu and 0.9 % Zn (normally 0.5 % Zn). Both massive and disseminated ores occur and ore minerals include pyrite with some pyrrhotite, chalcopyrite and sphalerite. Despite its importance, the area has attracted little geological research since the work of Vogt (1927). Several modern studies are, however, of importance to the understanding of the ore. These include Wilson (1968), who investigated the supposed nappe structure within the area, Rai's (1972) work on ore geochemistry, Grenne's (1975) petrological studies and the work of Boyle et al. (1979) east of the mine area which lead to the important discovery of an inversion zone and hence a large isoclinal fold within the Sulitjelma Amphibolite.

The Sulitjelma Area includes more than 20 deposits with a total tonnage in excess of 35 Mt (Cook et al. 1990). The average grades of the 25 Mt mined from 11 deposits between 1887 and 1991 were 1.84 % Cu and 0.86 % Zn. Contents of precious metals were 10 g/t Ag and 0.25 g/t Au (Cook et al. 1990). The deposits are concentrated in an area of 25 km2, and are located at varying stratigraphic-structural levels in the Otervann Volcanic Formation (Cook et al., 1990), also known as the Sulitjelma amphibolites, in the Upper Allochthon Køli Nappe Complex. The palaeotectonic setting of the volcanic rocks is disputed. According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex. Inclusions of Precambrian gneiss in the Gabbro have been interpreted to show that the ophiolite complex represents a fragment of an ensialic marginal basin (Cook et al. 1990). The gabbro has been dated to 437 ± 2 Ma (Pedersen et al. 1991), and because of the cogenetic relationships between the young gabbro and the volcanic rocks, it has been argued that the term ophiolite complex is inappropriate (Grenne et al. 1999). Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985). The whole rock package has been folded isoclinally, leading to a large-scale repetition of sedimentary and volcanic units. This also means that the ore units are repeated (Cook et al. 1990). The volcanic pile is divided into several units, and the sulphide deposits are found at different levels within these units (Figure 60). The deposits are further divided into a Southern and a Northern Ore Field. The Jakobsbakken, Sagmo and Anna deposits are in the southern part of the ore field. The Jakobsbakken deposit is the most zinc-rich of the deposits, containing 4.5 Mt of ore with 1.55 % Cu and 2.42 % Zn. It also is at a structurally lower position than the other two main deposits in the Southern Ore Field, closer to the underlying Furulund Schist. Most of the deposits are in the Northern Ore Field. The Ny-Sulitjelma and Bursi deposits are the structurally the lowest in this ore field, and are situated between overlying metabasalts of the so-called Giken Amphibolite Unit and the Furulund Schist (Cook et al. 1990). Structurally higher up in the Giken Amphibolite Unit is the Hankabakken–Palmberg ore zone. The largest of the deposits in the Sulitjelma field, Giken, is situated structurally above the Giken Amphibolite Unit and below a schist unit (the Leirelva Schist) equivalent to the Furulund Schist. The Giken deposit contained 10.5 Mt of ore, of which 5.8 Mt was mined, containing 2.25 % Cu and 0.7 % Zn. Further up structurally is the Charlotta deposit, which is located at the contact between the Leirelva Schist and the Lower Amphibolite Unit. It is possible that this is the same level as the Sagmo deposit in the Southern Ore Field. The Mons Petter deposit is the structurally highest ore zone in the Northern Ore Field, and is situated between the Lower and Middle Amphibolite Unit. The westernmost, small Furuhaugen deposit (0.52 Mt) has an uncertain structural position, but is possibly the highest deposit in the stratigraphy. Polyphase deformation with a high degree of folding and amphibolite-grade metamorphism has obliterated most primary textures and mineralogical zonation patterns in the Sulitjelma Ore Field. However, several of the deposits are underlain by alteration zones, and display zonation in base metals in accordance with classical VMS type deposits (Cook et al. 1990).

The Bursi deposit represent the lowest level of mineralization in the Sulitjelma ore district. The mineralization is a stratabound impregnation in brecciated chlorite schist. Folding in two phases resulted in formation of a dome structure in the otherwise flat-lying deposit. The deposit was mined from 1902 to 1975 and 1.83 mill. t of ore was produced with 1.5 % Cu and 0.31 % Zn. Reserves are estimated to 0.015 mill. t.

The gabbro has been dated to 437 ± 2 Ma (Pedersen et al. 1991), and because of the cogenetic relationships between the young gabbro and the volcanic rocks, it has been argued that the term ophiolite complex is inappropriate (Grenne et al. 1999). Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985). The whole rock package has been folded isoclinally, leading to a large-scale repetition of sedimentary and volcanic units. This also means that the ore units are repeated (Cook et al. 1990). The volcanic pile is divided into several units, and the sulphide deposits are found at different levels within these units (Figure 60). The deposits are further divided into a Southern and a Northern Ore Field. The Jakobsbakken, Sagmo and Anna deposits are in the southern part of the ore field. The Jakobsbakken deposit is the most zinc-rich of the deposits, containing 4.5 Mt of ore with 1.55 % Cu and 2.42 % Zn. It also is at a structurally lower position than the other two main deposits in the Southern Ore Field, closer to the underlying Furulund Schist. Most of the deposits are in the Northern Ore Field. The Ny-Sulitjelma and Bursi deposits are the structurally the lowest in this ore field, and are situated between overlying metabasalts of the so-called Giken Amphibolite Unit and the Furulund Schist (Cook et al. 1990). Structurally higher up in the Giken Amphibolite Unit is the Hankabakken–Palmberg ore zone. The largest of the deposits in the Sulitjelma field, Giken, is situated structurally above the Giken Amphibolite Unit and below a schist unit (the Leirelva Schist) equivalent to the Furulund Schist. The Giken deposit contained 10.5 Mt of ore, of which 5.8 Mt was mined, containing 2.25 % Cu and 0.7 % Zn. Further up structurally is the Charlotta deposit, which is located at the contact between the Leirelva Schist and the Lower Amphibolite Unit. It is possible that this is the same level as the Sagmo deposit in the Southern Ore Field. The Mons Petter deposit is the structurally highest ore zone in the Northern Ore Field, and is situated between the Lower and Middle Amphibolite Unit. The westernmost, small Furuhaugen deposit (0.52 Mt) has an uncertain structural position, but is possibly the highest deposit in the stratigraphy. Polyphase deformation with a high degree of folding and amphibolite-grade metamorphism has obliterated most primary textures and mineralogical zonation patterns in the Sulitjelma Ore Field. However, several of the deposits are underlain by alteration zones, and display zonation in base metals in accordance with classical VMS type deposits (Cook et al. 1990).

The Mons Petter deposit is representing the highest structural level in the northern ore field. It is divided in two ore bodies. Mons Petter I was the first ore produced from the Sulitjelma ore district and mining commenced in 1886, while Mons Petter II was found in 1971 and was mined until 1986. The latter was rich in copper and was easy to produce with a thickness up to 12 m. The total production from the mine was 2.5 mill. t with 1.75 % Cu and 0.48 % Zn.

The Sulitjelma Area includes more than 20 deposits with a total tonnage in excess of 35 Mt (Cook et al. 1990). The average grades of the 25 Mt mined from 11 deposits between 1887 and 1991 were 1.84 % Cu and 0.86 % Zn. Contents of precious metals were 10 g/t Ag and 0.25 g/t Au (Cook et al. 1990). The deposits are concentrated in an area of 25 km2, and are located at varying stratigraphic-structural levels in the Otervann Volcanic Formation (Cook et al., 1990), also known as the Sulitjelma amphibolites, in the Upper Allochthon Køli Nappe Complex. The palaeotectonic setting of the volcanic rocks is disputed. According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex.

Description
The Sulitjelma Area includes more than 20 deposits with a total tonnage in excess of 35 Mt (Cook et al. 1990). The average grades of the 25 Mt mined from 11 deposits between 1887 and 1991 were 1.84 % Cu and 0.86 % Zn. Contents of precious metals were 10 g/t Ag and 0.25 g/t Au (Cook et al. 1990). The deposits are concentrated in an area of 25 km2, and are located at varying stratigraphic-structural levels in the Otervann Volcanic Formation (Cook et al., 1990), also known as the Sulitjelma amphibolites, in the Upper Allochthon Køli Nappe Complex. The palaeotectonic setting of the volcanic rocks is disputed. According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex.

Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985). The whole rock package has been folded isoclinally, leading to a large-scale repetition of sedimentary and volcanic units. This also means that the ore units are repeated (Cook et al. 1990). The volcanic pile is divided into several units, and the sulphide deposits are found at different levels within these units. The deposits are further divided into a Southern and a Northern Ore Field. The Jakobsbakken, Sagmo and Anna deposits are in the southern part of the ore field. The Jakobsbakken deposit is the most zinc-rich of the deposits, containing 4.5 Mt of ore with 1.55 % Cu and 2.42 % Zn.

Polyphase deformation with a high degree of folding and amphibolite-grade metamorphism has obliterated most primary textures and mineralogical zonation patterns in the Sulitjelma Ore Field.

The Ny-Sulitjelma deposit is characterized by isoclinal folding, which have led to increased thickness of the ore and enrichment of Cu (3-4 %) in the upper part of the ore. The deposit is likely at the same stratigraphic level as the Hankabakken I deposit. Mining was carried out between 1893-1965 and 2.59 mill. t of ore was produced with 1.99 % Cu and 0.55 % Zn. The ore zone is insufficient explored towards depth and it is a possibility for increasing the reserves. At the same stratigraphic level is the Gudrun deposit, which produced 0.71 mill.t with 1.49 % Cu and 0.55 % Zn.

Abstract:
The eugeoclinal rocks of the Sulitjelma region occup a large depression in the Norwegian Caldonodrd betwwen the Nasafjell tectonic window of Precambrian rocks in the south and the Tysfjord window in the north. The age of the rocks is thought to be Cambro-Silurian. The regionl metamophism is mainly in greenschist facies in the lower units, amphibolite facies in the Gasak Nappe and greenschist to amphibolite facies in the Fauske Nappe. Some of the largest sulphide deposits in Norway are located near Sulitjelma. The different types of mineralizations occurring in the region are briefly described.

The Hankabakken mine was worked on two different ore bodies, Hankabakken I and II. Hankabakken II is a blind deposit, localized some 500 m NW from Hankabakken I. The thickness of the ore bodies were generally 3-5 m, and commonly with increasing Cu-content towards the hangingwall. Altogether 1.99 mill. t of ore was produced with 1.4 % Cu and 0.4 % Zn. Reserves are estimated to 0.5 mill. t.

The Giken deposit is divided into two ore bodies, Giken I and II. These are the largest of the Sulitjelma deposits and together contained 10.5 mill. t. of ore, of which 5.8 mill. t. was mined, containing 2.25 % Cu and 0.7 % Zn. There are two main ore types: 1) banded massive ore, which are commonly found in the hangingwall, above 2) impregnation ore. It is large variations in ore content from east to west, and the ore is strongly deformed and folded in two major phases. Reserves are estimated to 4.7 mill. t.

Abstract:
The eugeoclinal rocks of the Sulitjelma region occup a large depression in the Norwegian Caldonodrd betwwen the Nasafjell tectonic window of Precambrian rocks in the south and the Tysfjord window in the north. The age of the rocks is thought to be Cambro-Silurian. The regionl metamophism is mainly in greenschist facies in the lower units, amphibolite facies in the Gasak Nappe and greenschist to amphibolite facies in the Fauske Nappe. Some of the largest sulphide deposits in Norway are located near Sulitjelma. The different types of mineralizations occurring in the region are briefly described.

Description
The Sulitjelma Area includes more than 20 deposits with a total tonnage in excess of 35 Mt (Cook et al. 1990). The average grades of the 25 Mt mined from 11 deposits between 1887 and 1991 were 1.84 % Cu and 0.86 % Zn. Contents of precious metals were 10 g/t Ag and 0.25 g/t Au (Cook et al. 1990). The deposits are concentrated in an area of 25 km2, and are located at varying stratigraphic-structural levels in the Otervann Volcanic Formation (Cook et al., 1990), also known as the Sulitjelma amphibolites, in the Upper Allochthon Køli Nappe Complex. The palaeotectonic setting of the volcanic rocks is disputed. According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex. Inclusions of Precambrian gneiss in the Gabbro have been interpreted to show that the ophiolite complex represents a fragment of an ensialic marginal basin (Cook et al. 1990). The gabbro has been dated to 437 ± 2 Ma (Pedersen et al. 1991), and because of the cogenetic relationships between the young gabbro and the volcanic rocks, it has been argued that the term ophiolite complex is inappropriate (Grenne et al. 1999). Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985). The whole rock package has been folded isoclinally, leading to a large-scale repetition of sedimentary and volcanic units. This also means that the ore units are repeated (Cook et al. 1990). The volcanic pile is divided into several units, and the sulphide deposits are found at different levels within these units. The deposits are further divided into a Southern and a Northern Ore Field. The Jakobsbakken, Sagmo and Anna deposits are in the southern part of the ore field. The Jakobsbakken deposit is the most zinc-rich of the deposits, containing 4.5 Mt of ore with 1.55 % Cu and 2.42 % Zn. It also is at a structurally lower position than the other two main deposits in the Southern Ore Field, closer to the underlying Furulund Schist. Most of the deposits are in the Northern Ore Field. The Ny-Sulitjelma and Bursi deposits are the structurally the lowest in this ore field, and are situated between overlying metabasalts of the so-called Giken Amphibolite Unit and the Furulund Schist (Cook et al. 1990). Structurally higher up in the Giken Amphibolite Unit is the Hankabakken–Palmberg ore zone. The largest of the deposits in the Sulitjelma field, Giken, is situated structurally above the Giken Amphibolite Unit and below a schist unit (the Leirelva Schist) equivalent to the Furulund Schist. The Giken deposit contained 10.5 Mt of ore, of which 5.8 Mt was mined, containing 2.25 % Cu and 0.7 % Zn. Further up structurally is the Charlotta deposit, which is located at the contact between the Leirelva Schist and the Lower Amphibolite Unit. It is possible that this is the same level as the Sagmo deposit in the Southern Ore Field. The Mons Petter deposit is the structurally highest ore zone in the Northern Ore Field, and is situated between the Lower and Middle Amphibolite Unit. The westernmost, small Furuhaugen deposit (0.52 Mt) has an uncertain structural position, but is possibly the highest deposit in the stratigraphy. Polyphase deformation with a high degree of folding and amphibolite-grade metamorphism has obliterated most primary textures and mineralogical zonation patterns in the Sulitjelma Ore Field. However, several of the deposits are underlain by alteration zones, and display zonation in base metals in accordance with classical VMS type deposits (Cook et al. 1990).

The Charlotta deposit is divided in two ore bodies, Charlotta I and II. these bodies had quite an irregular variation with respect to ore content. Mining commenced in 1894 and lasted until 1991. A total of 3 mill. t of ore with 2.0 % Cu and 0.58 % Zn was produced.

According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex. Inclusions of Precambrian gneiss in the Gabbro have been interpreted to show that the ophiolite complex represents a fragment of an ensialic marginal basin (Cook et al. 1990). The gabbro has been dated to 437 ± 2 Ma (Pedersen et al. 1991), and because of the cogenetic relationships between the young gabbro and the volcanic rocks, it has been argued that the term ophiolite complex is inappropriate (Grenne et al. 1999). Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985). The whole rock package has been folded isoclinally, leading to a large-scale repetition of sedimentary and volcanic units. This also means that the ore units are repeated (Cook et al. 1990). The volcanic pile is divided into several units, and the sulphide deposits are found at different levels within these units. The deposits are further divided into a Southern and a Northern Ore Field. The Jakobsbakken, Sagmo and Anna deposits are in the southern part of the ore field. The Jakobsbakken deposit is the most zinc-rich of the deposits, containing 4.5 Mt of ore with 1.55 % Cu and 2.42 % Zn. It also is at a structurally lower position than the other two main deposits in the Southern Ore Field, closer to the underlying Furulund Schist. Most of the deposits are in the Northern Ore Field. The Ny-Sulitjelma and Bursi deposits are the structurally the lowest in this ore field, and are situated between overlying metabasalts of the so-called Giken Amphibolite Unit and the Furulund Schist (Cook et al. 1990). Structurally higher up in the Giken Amphibolite Unit is the Hankabakken–Palmberg ore zone. The largest of the deposits in the Sulitjelma field, Giken, is situated structurally above the Giken Amphibolite Unit and below a schist unit (the Leirelva Schist) equivalent to the Furulund Schist. The Giken deposit contained 10.5 Mt of ore, of which 5.8 Mt was mined, containing 2.25 % Cu and 0.7 % Zn. Further up structurally is the Charlotta deposit, which is located at the contact between the Leirelva Schist and the Lower Amphibolite Unit. It is possible that this is the same level as the Sagmo deposit in the Southern Ore Field. The Mons Petter deposit is the structurally highest ore zone in the Northern Ore Field, and is situated between the Lower and Middle Amphibolite Unit. The westernmost, small Furuhaugen deposit (0.52 Mt) has an uncertain structural position, but is possibly the highest deposit in the stratigraphy. Polyphase deformation with a high degree of folding and amphibolite-grade metamorphism has obliterated most primary textures and mineralogical zonation patterns in the Sulitjelma Ore Field. However, several of the deposits are underlain by alteration zones, and display zonation in base metals in accordance with classical VMS type deposits (Cook et al. 1990).

The Sagmo deposit is situated in the southern ore field in the Sulitjelma ore district. It is probably at the same stratigraphic level as the Charlotta deposit in the northern field. The Sagmo mineralization contains more pyrrhotite than pyrite, which is rather unusual in the Sulitjelma ores. Furthermore, the ore is enriched in copper against the footwall and zinc and lead towards the hangingwall. A total of 1.9 mill. t. ore was produced with 1.6 % Cu and 0.23 % Zn in the period 1906-1986.

Abstract:
The eugeoclinal rocks of the Sulitjelma region occup a large depression in the Norwegian Caldonodrd betwwen the Nasafjell tectonic window of Precambrian rocks in the south and the Tysfjord window in the north. The age of the rocks is thought to be Cambro-Silurian. The regionl metamophism is mainly in greenschist facies in the lower units, amphibolite facies in the Gasak Nappe and greenschist to amphibolite facies in the Fauske Nappe. Some of the largest sulphide deposits in Norway are located near Sulitjelma. The different types of mineralizations occurring in the region are briefly described.

Abstract
This mine was an important mine, but is now (2015) considered empty and hence it has been assessed as a deposit of no or little importance with minor economical importance.
Description
The Sulitjelma Area includes more than 20 deposits with a total tonnage in excess of 35 Mt (Cook et al. 1990). The average grades of the 25 Mt mined from 11 deposits between 1887 and 1991 were 1.84 % Cu and 0.86 % Zn. Contents of precious metals were 10 g/t Ag and 0.25 g/t Au (Cook et al. 1990). The deposits are concentrated in an area of 25 km2, and are located at varying stratigraphic-structural levels in the Otervann Volcanic Formation (Cook et al., 1990), also known as the Sulitjelma amphibolites, in the Upper Allochthon Køli Nappe Complex. The palaeotectonic setting of the volcanic rocks is disputed. According to Boyle (1989), the volcanic rocks form the extrusive part of the Sulitjelma ophiolite complex, underlain by sheeted dikes of the Mietjerpakte Intrusive Complex and below that the Sulitjelma Gabbro Complex. Inclusions of Precambrian gneiss in the Gabbro have been interpreted to show that the ophiolite complex represents a fragment of an ensialic marginal basin (Cook et al. 1990). The gabbro has been dated to 437 ± 2 Ma (Pedersen et al. 1991), and because of the cogenetic relationships between the young gabbro and the volcanic rocks, it has been argued that the term ophiolite complex is inappropriate (Grenne et al. 1999). Structurally below the volcanic rocks, there is a thick sedimentary sequence of schists, the Furulund Group, which contains fossils of Upper Ordovician to Lower Silurian age (Spjeldnæs 1985).
