The Vittangi property is located in northern Sweden approximately 3.0 km from grid power and 23.0 km to the town and railhead at Svappavaara. The graphitedeposits on the Vittangi property have the highest-grade JORC (2012) reported graphite resources in the world. The Nunasvaara deposit has an Indicated Mineral Resource containing 10.4 Mt at 25.6% graphite, based on a 10% graphite cut-off grade.(2020). The North and South Niska deposits contain an Indicated Resource of 4.6 Mt at 25.8% graphite, also based on a 10.0% graphite cut-off grade (2020).
The geology of the Vittangi property consists of a Proterozoic greenstone sequence of sedimentary, volcaniclastic, and intrusive rocks. Stratiform to stratabound graphite mineralization occurs at the Nunasvaara deposit as two individual, sub-vertical, 15–60 metre wide units. The Nunasvaara graphite units extend over 15.0 km of strike, of which less than 10% has been drill tested to date.
A Pre-Feasibility Study completed in May 2019 proposed an open-pit mining operation with on-site concentrator and coastal anode refinery to produce approximately 19,000 tonnes per year of a coated Lithium-ion battery graphite anode material, trademarked as Talnode-C. The refined product will be sold to Lithium-ion battery manufacturers.
Talga is expecting to complete a Feasibility Study in 2021 and is working towards obtaining all necessary development permits and approvals.
Trial mining commenced at the Vittangi project. The 2021 trial mining campaign is extracting an approximate 2,500-tonne sample of natural graphite from the Niska South deposit of Vittangi. The raw ore will be processed and refined into Li-ion battery anode in customer trials for electric vehicle market.
Depth extension drilling began at Vittangi and will test the Nunasvaara South, Nunasvaara North and Niska South targets to further explore the full potential of the graphite resource. The drill program is expected to be completed by mid-October, with internal studies of assay results beginning in Q4 2021.
