Growing West Australian lithium company
Drilling over an anomalous area 350m to the south of the main outcrop has confirmed spodumene-rich pegmatites at Manna 2. Manna was discovered by
The Mineral Resource is defined by 3,636m of drilling at relatively shallow depths comprised of 21 reverse circulation drillholes for 3,354m and four diamond drillholes for 282.15m. After acquiring an 80% interest in Manna, GL1 engaged Snowden Optiro to undertake a Mineral Resource estimate using data compiled by Breaker, including the reverse circulation drilling and diamond drilling results.
Lithium mineralisation at Manna is open in all directions demonstrating scope for significant Mineral Resource growth. Global Lithium is completing advanced planning and target generation work for a substantial exploration and drilling program of at least 20,000m.

The drilling database used to define the lithium mineralisation at the Manna deposit comprises 21 reverse circulation (RC) drillholes for a total of 3,354m and four diamond drillholes for a total of 282.15 m. With the further drilling planned the Company expects the maiden Mineral Resource will grow significantly. GL1 is working with consultants Resource Potentials to plan and design a drilling program that will grow the pegmatite resource, further upgrade the resource classification and provide material for additional metallurgical studies. The Company is currently working to obtain the necessary approvals for the drilling program and to plan the logistics for undertaking the drilling.
Geology and Mineralisation Interpretation
Greenstone sequences within the vicinity of the Manna lithium deposit are dominated by mafic and felsicintermediate igneous rocks, with minor sedimentary rocks, of the Kurnalpi Terrane of the Archean Yilgarn Craton. It is thought that the lithium-caesium-tantalum type (LCT) pegmatite swarm, which includes the Manna lithium deposit, is likely to be associated with the Cardunia granitoid body. Mineralisation at Manna remains open in all directions. Weathering of the pegmatite is negligible and fresh spodumene was observed at surface. Eleven sets of anastomosing mineralised pegmatite veins were interpreted. The lithium-mineralised zones of the pegmatites have been defined from geological logging and above a nominal cut-off grade of 0.4% Li2O. The pegmatite veins strike northeast-southwest and dip at -60-degree to -70-degree to the southeast. The main set of eight mineralised pegmatites at Manna 1 have been drilled over an area of 700m by 140m and to a depth of 200m. An additional three pegmatite veins at Manna 2 (to the southeast of Manna 1), have been drilled over an area of 300m by 40m and to a depth of 120m. The individual mineralised pegmatites are 1m to 14m thick and have an average thickness of 3.6m
