Further Positive Metallurgical Results at Authier

Brisbane, Nov 30, 2017 AEST (ABN Newswire) - Sayona Mining Limited (googlechartASX:SYA) (googlechartDMNXF:OTCMKTS) ("Sayona" or the "Company") is pleased to report the third phase of metallurgical testing results for the Authier lithium project.

- Flotation recoveries over 80% and concentrate grades greater than 6% Li20 achieved using unprocessed water from the Authier project site

- Testing demonstrates that unprocessed water from the project site can be utilised on a raw untreated basis

- Pilot metallurgical testing to commence in December 2017. Data will be used for the Definitive Feasibility Study

The new results have continued to demonstrate the ability to achieve 6% Li20 lithium concentrate grades at 80% metallurgical recoveries or better. In addition, two of the tests were conducted using unprocessed water collected at the Authier site with similar results to tap water.

The metallurgical testing program was undertaken with a new representative sample from the Authier deposit. The new sample represents both the expected feed grade and expected mineralogy of the deposit over the life-of-mine.

The new results will be incorporated into the Definitive Feasibility Study. A new diamond drilling program is underway and will provide approximately 5 tonnes of drill core to be used on a pilot scale metallurgical testing program.

Phase 3 Metallurgical Testing Program Overview

The objective of the Phase 3 metallurgical testing was to assess flotation performance with Authier project site water. The testing program was completed at SGS Lakefield.

The two most recent phases of metallurgical testing have included variations in the grind size, flotation residence times, reagent dosages, adjustments to magnetic intensity, using unprocessed Authier site water, and assessing the impact of waste dilution on metallurgical outcomes. The objective of the programs is to improve on the February 2017 Pre-Feasibility Study assumptions of a 5.75% concentrate at 80% metallurgical recovery. The new metallurgical testing program was undertaken with a new representative sample of the Authier deposit from drill core from the Company's Phase 1 and 2 diamond drilling programs. The new sample represents the average grade and expected mineralogy of the deposit over the life-of-mine. The sample was collected from three diamond drill cores and totaled approximately 63 kilograms.
