Våtmyrberget Project-permit location and access and the historic Näsberg iron mine-IMAGE
Tenure
Three permits covering an area of 54km2 were applied for and granted 2008. The permits are located within the Municipality of Piteå. The permits are held in the name of Hannans Scandinavia AB, a wholly owned subsidiary of Scandinavian Resources Ltd.
Regional & Local Geology
The Våtmyrberget Project covers part of the Näsberget layered mafic intrusive first identified by geologist Birger Filén. The Näsberget layered mafic intrusive belongs to the Jörn Intrusive Suite (1.90-1.88Ga) which also includes rocks of granodiorite, tonalite, monzonite and quartz-monzonite. Younger (1.88-1.86Ga) Svecofennian supracrustal rocks of the local Arvidsjaur Group surround the Näsberget layered mafic intrusive mainly to the west and north. The Arvidsjaur Group is dominated by felsic volcanics including trachydacite, quartz, feldspar and quartz-feldspar porphyritic rhyolite and dacite. The mafic component of the Arvidsjaur Group consists of basalt and andesite. Minor polymict conglomerate is found in the north of the Våtmyrberget Project. The Näsberget layered mafic intrusive contains both igneous and model layering which generally strikes northeast-southwest and dips steeply to the northwest. Minor ultramafic layering, consisting of thin bands of hornblendite, occurs in the south east of the intrusive (Filén 1988). The intrusive is considered prospective for iron, copper, nickel and platinum group elements (PGE’s).
The Våtmyrberget Project is also considered prospective for IOCG mineralisation given its proximity to a major, crustal scale, deformation zone located to the east of the Våtmyrberget Project and the presence of felsic volcanic rocks belonging to the Svecofennian aged (1.88-1.86Ga Arvidsjaur Group; this particular geological setting is very similar to that of the Kiruna district which hosts numerous Kiruna-type IOCG deposits.
Previous Exploration & Mining History
Iron ore was found at Näsberg as early as 1832 and mining started 5 years later. By 1833 the Mines Inspector had visited the discovery and noted that the ore occurs as veins which contained sulphides (pyrite). Ore sorting was by hand however production was minimal and by 1908 the mine had closed. Since the closure of the mine, numerous rock chips have been collected throughout the Våtmyrberget Project area; namely along the Byske River where in situ rock exposures can be found.
In 2004, Boliden AB held ground covering part of Scandinavian Resources Ltd current permit area and also ground to the south; two diamond holes were drilled outside of the current permit area. The holes intersected gabbro, andesite and minor tonalite; no significant assays were reported. Boliden AB also collected detailed field mapping measurements of the area.
Exploration Completed
Recent work by Scandinavian Resources Ltd has included limited prospecting and rock chip sampling. Multi-element anomalism was encountered from three samples collected from felsic volcanics near the northern contact of the Näsberget layered mafic intrusive; results include 8.7ppm Ag, 0.9% Cu, 2,470ppm W, 0.1ppm Au (KS08204), 4.56% Cu, 32.5 ppm Ag, 1,540 ppm W, 0.1 ppm Au (KS08105) and 29.8 ppm Ag, 2.47% Cu, 32.3% Fe, 370 ppm W, 0.39 ppm Au (KS08106). The characteristic metal assemblage of iron-gold-copper-bismuth-cobalt-vanadium-tungsten-molybdenum indicates a fractionated (A-type) magmatic system as the source for the potential ore fluids at Våtmyrberget with considerable potential for magnetite copper-gold skarn and porphyry copper-gold style (molybdenum-tungsten rich) mineralisation developed above and around the magmatic source rocks.
Two samples have been collected from the Näsberget layered mafic intrusive and returned values of: 3,670 ppm Cu, 2,570 ppm Ni, 516ppm Co and >50% Fe (KS08108) and 13.3 ppm Ag, 1.64% Cu, 0.18 ppm Au (KS08101).
