Sayona Mining Improves Authier Metallurgy Results

THE BOURSE WHISPERER: Sayona Mining (ASX: SYA) reported the third phase of metallurgical testing results for the company’s Authier lithium project in Quebec, Canada.

Sayona Mining declared the latest results continued to demonstrate the project’s ability to achieve six per cent lithium dioxide (Li20) lithium concentrate grades at 80 per cent metallurgical recoveries or better.

The company carried out the metallurgical testing program using a new representative sample from the Authier deposit, which it said was representative of both the expected feed grade and expected mineralogy of the deposit over the life-of-mine.

Sayona will be incorporating the new results into its Definitive Feasibility Study.

A new diamond drilling program is now underway and will provide approximately five tonnes of drill core to be used on a pilot scale metallurgical testing program.

“The objective of the Phase 3 metallurgical testing was to assess flotation performance with Authier project site water,” Sayona Mining said in its ASX announcement.

“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 per cent concentrate at 80 per cent 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.”
