Bradda Head Lithium Limited Provides Updates on Mineral Resource Expansion Basin Project

Bradda Head Lithium Limited announcea new Mineral Resource Estimate (MRE) at the Company's 100% owned Basin Project, Arizona. The updated MRE was prepared in accordance with Canadian National Instrument 43-101 (Standards of Disclosure for Mineral Projects) (NI-43-101) by ABH Engineering Inc. (ABH). The Company is reporting a new MRE consisting of 99kt Of lithium carbonate equivalent ("LCE") at an average grade of 929 ppm lithium in Measured classification, 560kt of LCE at 860ppm Li in the Indicated classification; and 2,175kt of LCE at 808ppm Li in the Inferred classification following the completion of drilling, reception and analysis of geochemical results, and new modeling of the Basin project. As per the Gross Overriding Royalty Agreement ("Royalty Agreement") with the Lithium Royalty Company ("LRC"), the new contained LCE Tonnage surpassed the contracted threshold of 2.5Mt and has enabled the Company to trigger the payment of US$3.0 million from LRC to Bradda Head. The Company has requested this payment be made, and therefore expects to be well funded for the future, including drilling plans at San Domingo Arizona, near surface Spodumene bearing pegmatite opportunity. Highlights: The total new Mineral Resource now comprises 20 million tonnes in the Measured category at 929ppm Li consisting of 99kt LCE, 122 million tonnes in the Indicated category at 860 ppm Li consisting of 560kt LCEand 506 million tonnes in the Inferred category at 808 ppm Li, carrying 2,175 kt LCE · The resource now contains 20 million tonnes of 929ppm lithium for 99Ktons of LCE in the Measured category, the first ever in this category at Basin. · As per the Royalty Agreement, BHL has formally requested payment of US $3.0 million from LRC; documentation has been submitted per verification by ABH Engineering Inc. ("ABH"). · The results of the 2024 drilling programme demonstrate extensive lateral continuity from Basin East through to Basin North, identifying impressive consistency in the stratigraphic continuity of the Upper Clay and grade profile over a 3.0 x 2.0 km area that remains open to the north, east, and west. · It's important to note thatthe Upper Clay Unit includes a continuous High-Grade layer which has an average grade of some 1,190 ppm Li, and is on average 15m thick and crops-out in Basin East potentially forming part of a phased mining processing operation that would clearly enhance early stages of mining and overall project economics. Five out of the eight drill holes encountered lithium mineralized "Lower Clay" which makes a significant contribution to the overall resource, particularly as the Company is able to connect the Lower Clay mineral resource from Basin East to the northern edge of Basin North, a distance of 3.0km. · The average in-situ grade of the Inferred Basin East Mineral Resource has decreased slightly from 900 to 822 ppm Li, a 9% decrease. · ABH applied a new cut off grade of 550ppm Li to report the Mineral Resources and demonstrate reasonable prospects of eventual economic extraction ("RPEEE"). This is the same cut off grade previously used by SRK (550 ppm; effective 28th September 2023). · ABH were selected to complete the Mineral Resource Update analysis based upon their prior work in clay deposits across Nevada, having significant expertise and knowledge. They applied a robust approach to both the in-situ density measurement and the cut off grade utilised. The in-situ density measurement was based upon several hundred core sample measurements using best practices. Following the 2024 drill program and new geologic mapping, the Company's understanding of the Basin project has increased significantly, resulting in renewed encouragement of extensive exploration opportunities for growth over the remainder of Basin North and all of Basin West where the Company continue working on permits. · The complete NI43-101 Technical Report by ABH will be available on the Company's website and SEDAR by or before August 12, 2024. The updated 2024 Mineral Resource Estimate ("MRE") at Basin authored by ABH Engineering Inc. ("ABH"), is reported in accordance with the terminology and definitions given in the Canadian Institute of Mining, Metallurgy and Petroleum guidelines, comprising: a Measured Mineral Resource of 20 million tonnes at an average grade of 929ppm for a total of 99kt of LCE, an Indicated Mineral Resource of 122 million tonnes at an average grade of 860ppm Li for a total of 560 kt LCE and an Inferred Mineral Resource of 506 million tonnes at an average grade of 808 ppm Li for a total of 2,175 kt LCE. ABH has applied basic technical and economic assumptions for open pit mining (mining and selling costs, mining recovery and dilution, pit slope angles) and processing factors (Li recovery, processing costs), to determine which portion of the block model has reasonable prospects for eventual economic extraction as required by CIM. To achieve this, the Mineral Resource has been subject to a pit optimisation study and cut-off grade analysis. Over one quarter, or 115 million tonnes of the contained LCE, is in a High-Grade zone within the Upper Clay zone with an average grade of some 1,190 ppm Li. This High-Grade zone gives Bradda Head further optionality and could have important economic implications for a potential future mining operation. The shallow nature of the High-Grade zone, which crops out in Basin East, would likely result in a low strip ratio, enabling High-Grade ore to be scheduled early in a possible mine plan as it sits in the upper part of the deposit. The graph above illustrates the growth of the Basin resource since 2018 and the near exponential growth since 2023 when the total LCE grew significantly in the inferred and indicated categories, not to mention the new measured category. Additional growth is anticipated once additional permits are obtained for Basin West and expansion of existing permit for Basin North. The Upper Clay, Upper Higher-Grade and Lower Clay horizons show remarkable extent and continuity throughout the drilled parts of the Basin Project and remain open to the north, west, and east indicating significant exploration potential in the overall Basin property. Geological mapping, surface samples assayed for lithium and geophysical (Ground Penetrating Radar) survey work also indicate similar clay layers are likely present throughout the majority of the Basin West license area. Recent surface mapping over Basin West has identified substantial Upper and Lower Clay horizons, separated by tuff and basalt layers, providing stratigraphic context. Both tuff and basalt layers are found above the Upper and Lower Clays, indicating strong optimism in discovering additional clays in the northwest quadrant of Basin West. As such, with further wide-spaced drilling Bradda Head sees excellent potential to increase the resource base substantially.
