Paddington, QLD / February 15, 2018 / JMN Wire / Sayona Mining Limited (ASX: SYA) ("Sayona" or the "Company") is pleased to announce the commencement of the pilot plant program for the Authier Lithium Project. The pilot program is being completed by SGS Canada (“SGS”) at Lakefield, Ontario. SGS has extensive experience in developing spodumene concentration flowsheets. Over the last ten years, SGS has operated pilot plants for several Canadian hard rock lithium deposits.
Approximately 5.5 tonnes of mineralised pegmatite ore was collected during the Phase 3 drilling program in December 2017 (Figure 1). The diamond drill core was assayed and stagecrushed to the appropriate particle size to feed the pilot plant (Figure 2). 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 (Figure 3). The pilot plant is scheduled to operate for 100 hours at a feed rate of 50 kg/hour.
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”.
