Stage I test work is now complete with stage II test work underway

Infinity Lithium Corporation Ltd (ASX:INF) has confirmed its updated pre-feasibility study (PFS) is on track for completion in June-July this year.

Notably, stage I test work has been completed which focused on metallurgical test work designed to confirm previous upgrade factors from the November 2018 scoping study.

The PFS consultant, Wave International, was able to complete the test work and produce suitable amounts of concentrate for the stage II hydrometallurgical test work.

Stage II test work is designed to develop the sulphate-roast-water-leach (‘SRWL’) flowsheet to a PFS standard.

Stage I focussed on the crush-mill and beneficiation stages, stage II covers ‘roast and leach’ stages

As per the flowsheet above, after stage II, the leach solution produced will move to stage III, the final stage, where through a process of purification and crystallisation lithium hydroxide will be produced.

Wave International's Director Ryan Hanrahan commented: “The confirmation of the scoping study beneficiation recoveries and grades is an encouraging first major milestone for the San Jose PFS.

"These results provide a solid platform on which to progress the PFS engineering and ongoing metallurgical test work.

"As a team we are excited to be supporting INF to take the next step in de-risking the San Jose project and progressing towards development.”
