Advanced WA lithium project on the rise

Global Lithium Manna

Global Lithium is on track to deliver the definitive feasibility study for its Manna lithium project in Western Australia.

The company has now received final results from its extensive drilling campaign in 2023. This comprised over 60,000m of reverse circulation and diamond drilling.

Global Lithium has now drilled 420 holes at Manna and is developing an advanced understanding of the composition of the ore body.

The Manna lithium project currently hosts a mineral resource of 36 million tonnes at 1.13 per cent lithium oxide. Using these drill results, Global Lithium is expected to deliver an updated mineral resource estimate later this year.

The company has also worked to significantly de-risk the project, driving up recovery rates to improve the project’s economics.

Testwork focussing on magnetic separation and mica pre-flotation stages has increased lithium oxide recoveries from 70 per cent to 75 per cent for spodumene composite ore samples.

A total of 66 flotation tests have been completed producing a spodumene product grading at 5.6–6.5 per cent lithium oxide.

Global Lithium is exploring additional testwork to unlock further recovery improvements via reduced slimes losses, reprocessing of magnetic separation tails, and engaging with reagent suppliers to optimise spodumene flotation circuit operating conditions.

Key approvals such as environmental and Native Title negotiations are well advanced, with the mining lease expected to be granted once the latter agreement is finalised.

“During the June quarter the company expects to deliver an updated mineral resource estimate and further advance its metallurgical testwork program, with both to be incorporated into the DFS later this year,” Global Lithium managing director Ron Mitchell said.

“Our exploration team is also set to commence its 2024 drilling program at the project which will focus on new targets aimed at extending the Manna deposit and adding life of mine.”

Specifically, the 2024 drilling campaign will be targeted along the Manna fault zone to the southwest of the Manna deposit to test for shallow spodumene bearing pegmatites.

Approximately 6000m of drilling is planned for the second quarter of the year.
