Authier Pilot Metallurgy Program Update
Authier Pilot Metallurgy Program Update
Brisbane, April 13, 2018 AEST (ABN Newswire) - Sayona Mining Limited (ASX:SYA) (OTCMKTS:DMNXF) ("Sayona" or the "Company") is pleased to report the following update on the pilot plant program underway at SGS Lakefield for the Authier Lithium Project.

The Company has completed the batch and locked cycle phase of the pilot program which had the aim of establishing the optimal conditions for the continuous pilot plant program. The pilot plant operations have now commenced.

During batch and locked cycle testing, the Company has been able to achieve concentrate grades of 6% at metallurgical recoveries of 80%.

Approximately five tonnes of mineralised pegmatite will be processed through the pilot plant. The plant will operate for a minimum of 100 hours at a feed rate of 50 kilogram per hour. The pilot program involved stage-crushing the ore to -3.35mm (see Figure 1 in link below). The crushed ore then passes through a grinding mill, cyclones for de-sliming, magnetic separation for iron removal, mica and spodumene flotation (see Figure 2 and 3 in link below).

The objectives of the pilot plant program include:

- Confirm the flowsheet and process parameters for concentrate production;

- Produce engineering data for equipment sizing and plant design; and

- Generate ~500 kg of spodumene concentrate for downstream testing and marketing purposes.

The results of the pilot program are expected to be available by the end of April and will be incorporated into the Definitive Feasibility Study ("DFS") which will be completed during Q2 2018. On completion of the pilot program, optimisation work will continue with the objective of maximising metallurgical recoveries and de-risking the metallurgical performance of the full-scale operations.

SGS Canada Inc. has considerable experience in developing spodumene concentration flowsheets. Over the past 10 years, SGS has operated pilot plants for several North American hard rock lithium deposits.
