Bradda Head Lithium Ltd. announced the commencement of drilling at its Basin Project, Arizona. As indicated in the Company's March 4, 2024 announcement, Bradda Head initiated and then mobilised equipment to the Basin North side of the project and has commenced drilling. The six-hole program is designed to significantly expand the Company's lithium in clay Mineral Resource Estimate ("MRE").

As previously described, this six-hole program will build upon Bradda Head's 1.085MT Lithium Carbonate Equivalent ("LCE") by drilling holes 1.2 kilometers towards the north on newly permitted drill holes. The objective of this program is to add a minimum of 1.5MT LCE, surpassing the benchmark of 2.5MT LCE which will trigger the final USD 3 million royalty payment from Lithium Royalty Company ("LRC") to Bradda Head. The drilling program is anticipated to finish towards the end of April, 2024.

Program Summary: Six-hole core drilling program of approximately 8,800 feet (2,680m) planned; Program anticipated to expand LCE from 1.085MT to >2.5MT; Step-out drill holes at 500 to 700m spacing to maintain Inferred category of MRE; One hole will be drilled into Precambrian basement in center of gravity low; Gravity low may represent extensively thick clays both in the Upper, Lower, and Basal Red-Beds; Holes will test Lower Clay to expand tonnage potential and thicker sequence correlative with gravity low which also has the potential for exceptional lithium grades. This program is focused on significantly thicker clay sequences, consistent if not higher lithium grades and thicker lower clay sequence, with the potential to also discover new clays within the nearly 2km2 gravity low. Like previous drilling programs conducted at Basin, drill holes will be vertical, but when clay horizons are encountered the Company's plan is to convert to a triple tube core capture technique which ensures high recovery and provides the Company with many options for sampling, density measurements, and geotechnical data for future studies.

The Company received an affirmative decision from the BLM on February 28th with confirmation that it could conduct exploration drilling on the Basin North notice of intent ("NOI") amendment and based on a reclamation bond increase with permission to proceed on 3.8 acres of surface disturbance. Earth moving equipment has prepared new access roads and sites, and core drillers have commenced operations.

Stock Option Plan Approval The Company also takes this opportunity to make a regulatory confirmation as required by the TSX-V: Further to its press release dated 24 November 2023 announcing that all resolutions proposed at the annual general meeting held on 23 November 2023 had been passed, Bradda Head confirms that amongst the resolutions passed, the Stock Option Plan Mr. Wilkins consents to the inclusion of the technical information in this release and context in which it appears. Technical Glossary Kt Thousand tonnes Ppm Parts per million Exploration Target: An estimate of the exploration potential of a mineral deposit in a defined geological setting where the statement or estimate, quoted as a range of tonnes and a range of grade (or quality), relates to mineralisation for which there has been insufficient exploration to estimate a Mineral Resource. Inferred Mineral Resource That part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.

Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
