Approximately 5.5 tonnes of mineralised pegmatite ore was collected during the Phase 3 drilling program in December 2017 (see Figure 1 in link below). The diamond drill core was assayed and stagecrushed to the appropriate particle size to feed the pilot plant (see Figure 2 in link below). Two composite pilot plant feed samples have been prepared to represent Years 0 to 5 and Years 5+ of the operation. The pilot plant flowsheet comprises grinding, de-sliming, magnetic separation, mica and spodumene flotation (see Figure 3 in link below). The pilot plant is scheduled to operate for 100 hours at a feed rate of 50 kg/hour.
The objectives of the piloting program are to produce a 6% Li20 concentrate at recoveries of greater than 80% and confirm:
- Finalisation of the flowsheet and processing parameters for spodumene concentrate production developed during the Pre-Feasibility Study;
- Produce engineering data for equipment sizing and plant design; and
- Generation of spodumene concentrate for downstream lithium carbonate testing and marketing purposes.
The data collected from the piloting program will be incorporated into the Definitive Feasibility Study which is expected to be completed during the 2Q 2018.
Corey Nolan, Chief Executive Officer, commented "The objective of the pilot program is to further refine the design and confirm the operating parametres for the Authier process plant, in order to de-risk the plant construction, commissioning and ramp-up. The Company is focused on the rapid progression of the project towards production to capitalise on the strong projected price outlook for spodumene concentrates".
