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 graphite deposits 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.
In July 2021, Talga announced the results of a Detailed Feasibility Study that confirms Vittangi’s potential to produce 19,500 tonnes per annum from 100,000 tpa of Vittangi graphite ore over 24 years life of mine. The study envisions an open-pit mining operation capable of producing a coated lithium-ion battery graphite anode material, trademarked as Talnode-C, directly to customers via a vertically integrated mine-to-anode operation.
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.
