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:
Bekkesedimenter fra 334 prøvelokaliteter i Sulitjelma-området ble innsamlet med en prøvetetthet på 1 prøve pr. 10 km2. Rapporten inneholder tabeller og resultkart over 28 elementer oppsluttet med HNO3 og bestemt med ICAP.

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:
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.
