Central Sweden Vanadium Projects

The Central Sweden Projects comprise three early-stage exploration projects at Sumåssjön, Simesvallen and Kullberget. The projects cover various mafic sills and intrusive bodies associated with the Ljusdal Batholith (LJB), a composite granitoid body extending over an area of approximately 130 km x 100 km and which has been intruded by iron-titanium-vanadium mineralised mafic intrusions.  Previous exploration has outlined a number of prospective targets which were the subject of historical mineral estimates at Sumåssjön and Simesvallen, while historical trial mining occurred at Kullberget-Storåsen.

 

The Sumåssjön Project area contains two major mafic units, represented by:

  • an eastern magnetic unit, which is 7.5 km long, containing vanadium mineral occurrences and areas of historical mining activity
  • a western magmatic unit, forming an arcuate 3.5 km long magnetic geophysical anomaly. Associated with the western magnetic anomaly are recorded vanadium occurrences and historical mining sites

 

The Simesvallen tenement covers a structure which is an approximately 15km long magnetic unit, folded into elliptical form, potentially indicating sills or lopolithic gabbro intrusions. The known mineralisation is hosted within a mafic intrusion with a 1.5 km x 0.75 km surface exposure.  To date, three prospect areas are defined, namely Simesvallen East, Spannarslatten and Svedasen.

 

  • Simesvallen East is centred on the area drilled historically, where modelling of the ground magnetic data has shown that the magnetic body is at least 24 m thick at SIM82003 and increases to approximately 50 m thick some 340 m to the east.
  • At Spannarslatten, an intense (to 745 nT), elongated ground magnetic anomaly extends east-west for at least 1,000 m in length and is modelled as two shallow magnetic bodies dipping 35˚ to the north with a thickness of 40 m and 30 m, respectively.
  • At Svedasen, the ground magnetic data is modelled as a circular, flat-lying intrusion comprising two magnetic southeast-dipping bodies about an east-west axis and varying in thickness from 18 m to 96 m.

 

The Kullberget Project represents the northwestern-most tenement in the Central Sweden project area and is situated 15 km directly northwest of the town of Ljusdal. A rail line connects Ljusdal to the port at Galve 150 km to the south.  The Kullberget – Storåsen structure comprises a magnetic anomaly, approximately 6 km long and divided into western (Kullberget) and eastern (Storåsen) sections. At Kullberget, vanadium-titanium-magnetite mineralisation outcrops in a norite-gabbro, where previous rock chip geochemical sampling returned 20% Fe, 7.6% TiO2 and 0.53% V. At Storåsen, limited historical trial mining of this intrusive has occurred with historical geochemical sampling demonstrating the outcropping vanadium mineralisation grades between 12-20% Fe, 0.94-6.0% TiO2 and from 0.06-0.1% V.
