WA hard-rock lithium projects - Manna and Marble Bar – achieves a 148.5% resource increase to 50.7Mt @ 1.0% Li2O
Growing multi-asset West Australian lithium company Global Lithium Resources Limited (ASX: GL1, “Global Lithium”, “GL1” or “the Company”) is pleased to announce a game-changing updated JORC Mineral Resource Estimate (MRE) for its two 100%-owned hard rock lithium projects in Western Australia.
Key Highlights
- 230% increase in the Manna Lithium Project’s Mineral Resource to 32.7Mt @ 1.0% Li2O
- 71% increase in the Marble Bar Lithium Project’s Mineral Resource to 18.0Mt @ 1.0% Li2O
- Combined Mineral Resource increases from 20.4Mt to 50.7Mt across GL1’s two 100%-owned hard rock lithium projects in WA
- A further Mineral Resource update incorporating an additional ~20,000m of drilling at Manna expected to be announced in CY 2023
- Both projects demonstrate significant scope for further growth in Mineral Resources
- Additional targets already identified as part of the 2023 drilling program
- 35,000m drilling program planned at Manna, aiming to further increase the Mineral Resource and convert more tonnage into the “Indicated” classification
- Scoping and feasibility studies to commence shortly to progress Manna development into an operational mine
- Marble Bar exploration area expanded from 15km to 25km of prospective strike
- Further 20,000m of drilling and large-scale geochemical exploration planned over the greater Marble Bar area in 2023
- Commercial discussions with a range of OEMs, battery and chemical companies continue to gather momentum
In 2022, Global Lithium has performed large scale drilling programs across both its Manna Lithium Project (“Manna”) in the Goldfields region and Marble Bar Lithium Project (“MBLP”) in the Pilbara region, which has enabled a significant upgrade to the Company’s Global Mineral Resource.
Global Lithium Managing Director, Ron Mitchell commented,
“These game-changing Mineral Resource upgrades, at our 100%-owned Western Australian hard-rock lithium projects, are a great outcome for GL1 following the nearly 85,000m exploration programs we have undertaken safely during 2022.
I am delighted to oversee such a significant increase in the Mineral Resource for the Company across its portfolio. The GL1 geological team, drilling contractors, traditional owners and external advisors have all worked tirelessly over the last eleven months to deliver this result and I congratulate each and every one of them on the tremendous success of the campaign.
The Mineral Resource upgrade at Manna provides us with a compelling base to progress scoping and feasibility studies for the project, with a further Mineral Resource update expected in CY 2023. We are now in the fortunate position to own 100% of Manna following the consolidation of Breaker Resources’ 20% stake in November 20221. This provides us with maximum control and flexibility to expedite these studies with the goal of bringing Manna into production as soon as practicable. We expect to announce the results of the scoping study for Manna in Q1 next calendar year.
As we look forward, 2023 is shaping up as another step-change year for GL1.”
The Manna Lithium Project
In November 2022, Global Lithium secured 100% ownership of Manna, located 100km east of Kalgoorlie. This acquisition increased the land holding area for Manna by nearly five times, allowing for a larger exploration campaign to be executed to locate additional drill targets for the Mineral Resource expansion drilling program that will continue throughout 2023.
The Manna Lithium deposit remains open in all directions and the current resource expansion drilling program will continue throughout 2023, with an additional 35,000m utilising both RC and DD drilling techniques planned.
During the 2022 drilling program more than 33,685m of reverse circulation drilling and 6,138m of diamond core was drilled across the deposit. The main focus of this program was to expand the maiden Mineral Resource of 9.9Mt @ 1.14% Li2O.2 This was achieved by testing the deposit along strike in both directions and extending the known lithium-bearing pegmatites down dip. This drilling program proved to be extremely successful as demonstrated in this significant Mineral Resource upgrade.
The current drilling program results included assays up to mid-November 2022 that were utilised in this current resource update with a large number of samples still to be assayed and incorporated into the model. This with the additional surface expressions evident from this program, but as yet untested, have afforded the Global Lithium team significant scope for additional targets within the existing Manna Project Area to be tested as part of its planned 2023 resource update.
The diamond core collected from this year’s drilling program totalled ~2,000kg of lithium-bearing pegmatites across 20 drill holes, providing a complete set of representative core for the metallurgical testing program that will start in January 2023.
