The DFS is expected to be completed late in the June quarter this year

Sayona Mining Ltd (ASX:SYA) has completed the operation of its pilot plant program in Canada in preparation for completion of a definitive feasibility study (DFS).

The pilot plant operated for over 100 hours and produced over 400 kilograms of spodumene concentrate.

Feed samples for the pilot plant were taken from the Authier project representing potential future mining material.

The objectives of the piloting program were to produce a 6% lithium oxide concentrate at recoveries of greater than 80%.

Dan O’Neill, Managing Director, commented “The company is pleased with the excellent results achieved during the program, enabling the final design of the plant for the DFS.

“The program assists in de-risking the metallurgical parameters for the plant construction, commissioning and ramp-up periods.

“Over the next six months, the company will continue to undertake further testing targeting improvements to the operating parameters of the plant, including a testing program at the McGill University.”

Work continues towards DFS completion

The optimised pilot flow sheet was able to achieve a concentrate grading 6.0% lithium oxide at a 79% recovery.

The pilot program has confirmed the final process flow sheet and operating parameters for the DFS which is expected to be completed late in the June quarter.

Further testing will continue over the next six months targeting further optimisation and improvements to the flow sheet and operating parameters.
