Global Lithium Resources Limited announced a game-changing updated JORC Mineral Resource Estimate (MRE) for its two 100%-owned hard rock lithium projects in Western Australia. 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. 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.
