According to Mining News Pro - The demo plant will include gravity, heavy media, flotation and magnetic circuits. The PAK deposit naturally contains up to 4.5% lithium oxide, and that will be upgraded to 6.0% to 7.2% in the plant.

Frontier outlined five key goals for the demonstration plant:

- Produce high quality technical grade concentrates (7.2% Li2O) for glass and ceramics markets;
- Produce high quality chemical grade concentrates (6% Li2O) for the lithium battery market;
- Qualify products that meet specific customer and application requirements to secure North American and European offtake agreements;
- Validate and optimize the mining and milling technology and flowsheet design in advance of finalizing the phase two commercial production feasibility study; and
- Serve as a training facility for the local workforce to maximize local benefits of the future mining and milling operations.

The PAK deposit has a measured and indicated resource of 7.5 million tonnes of 2.02% lithium oxide and an inferred resource of 1.8 million tonnes of 2.10% lithium oxide. The mineralization has a rare technical or ceramic grade spodumene with low inherent iron (below 0.1% ferric oxide) as per the preliminary feasibility study  disseminated on April 16, 2018.
