Talga’s Vittangi Anode Project in northern Sweden includs a graphite mining and mineral processing operation at Talga’s Nunasvaara South deposit, located within the Vittangi Project, and an integrated anode refinery near the Port of Luleå.
The Company is now finalising the environmental permit for the Luleå anode refinery site. |

The Nunasvaara South deposit is located on licence Nunasvaara nr 2 and the Nunasvaara North prospect is located on licence Vittangi nr 2. All licences are owned 100% by the Company’s Swedish subsidiary, Talga AB. The licences are wholly-owned by the Company.

Summary:
The bedrock geology of the Vittangi Graphite Project ("Vittangi") area is dominated by greenstones (basalts to andesites), metasediments (quartzite, graphite schist, marble) and metadolerites which form part of the 2.0-2.3 billion year age Vittangi Greenstone Group.
Within Vittangi a prominent graphitic schist unit occurs, the Nunasvaara Member, consisting of exceptionally evenly distributed, highly crystalline, very fine graphite flakes. The graphite mineralisation of the Nunasvaara South Resource (containing the Nunasvaara South Probable Ore Reserve) comprises sub-vertical, 20-30m+ wide, 1200m-long lithologically continuous units of very fine-grained grey to black graphite rock containing up to 46% graphitic carbon (Cg). The resource, which outcrops, has been modelled to a depth of ~220m and the mineralisation remains open both along strike and at depth.
The mineralisation at Nunasvaara and Niska comprises two sub-vertical, lithologically continuous units of very fine grained, dark-grey to black graphite containing 10-46% graphitic carbon. The units range in thickness from ~15-100m. The hangingwall is comprised of mafic volcanoclastics and tuffaceous units and the footwall to the mineralisation is a mafic intrusive (dolerite-gabbro). The graphite units are regionally extensive over many kilometers and are interpreted to have developed in a shallow freshwater basin in the early Proterozoic (Circa 2.0 billion years). Subsequent deformation, possibly re ........
Summary:
The DFS considers an open pit mining scenario that will extract ore using conventional drill and blast processes due to the relatively simple structural and shallow nature of the chosen pit shell in the deposit. The operation is planned to use standard small-scale truck and shovel equipment on a contractor basis and operate 6 months per year.
The Mine is scheduled to produce approximately 100,000 tonnes per annum (“tpa”) of run-of-mine (“ROM”) graphite ore over a total mine life of 24 years.
A mining contractor will be used to extract the waste and the graphite ore using standard open pit mining methods, i.e. drilling and blasting followed by loading and hauling. The mined ore will be hauled to the ROM stockpile where it will be crushed (primary to tertiary) then conveyed directly to the concentrator. Mining operations are to be active only during the second and third quarter of each year.
Current design parameters are a bench height of 20m, with a berm width of 5m, battered to give an overall pit slope of 47º.
The proposed mine comprises a series of open pits to be mined along the strike of the deposit. Based on achieving a consistent head grade for the processing plant mining operations will start in Pit 4 area and then merge into a single larger open pit comprising Pit 4 through to Pit 1 via a series of pushbacks and extensions. Soils will be stockpiled, seeded and maintained over the duration of the mine operation for use in ........
