Cinovec is an historic tin mine, incorporating a significant undeveloped tin resource with by product potential including tungsten, lithium, rubidium, scandium, niobium and tantalum.
Cinovec is one of the largest undeveloped tin deposits in the world. Cinovec also hosts a partly overlapping hard rock lithium deposit.
The deposit appears amenable to bulk mining techniques and has had over 400,000 tonnes trial mined as a sub level open stope.
The project has successfully manufactured >99.5% pure lithium carbonate using an industry proven, sodium sulphate roast-based flow-sheet from mica-concentrate from the Cinovec Project.
The roasting flow-sheet reflects a simplified version of the well-proven technology that converts spodumene concentrate to lithium carbonate. Numerous lithium carbonate plants currently employ this technology internationally.
As of February 2017 the JORC-compliant resource is
Lithium Indicated Resource increased 3.9 Mt LCE, contained in 347.7Mt @ 0.45% Li2O and 0.04% Sn (0.1% Li cut off)
Lithium Total Resource increased 11.8% to 7.0 Mt LCE, contained in 656.5 Mt @ 0.43% Li2O and 0.04% Sn (0.1% Li cut off)
