Commencement of Drilling at Basin Project

Bradda Head Lithium Ltd (AIM:BHL, TSX-V:BHLI), the North America-focused lithium development group, is pleased to announce 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 US$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.

About Bradda Head Lithium Ltd.

The Basin East Project has an Indicated Mineral Resource of 17 Mt at an average grade of 940 ppm Li and 3.4% K for a total of 85 kt LCE and an Inferred Mineral Resource of 210 Mt at an average grade of 900 ppm Li and 2.8% K (potassium) for a total of 1.09 Mt LCE. In the rest of the Basin Project SRK has determined an Exploration Target of 250 to 830 Mt of material grading between 750 to 900 ppm Li, which is equivalent to a range of between 1 to 4 Mt contained LCE. The Group intends to continue to develop its three phase one projects in Arizona, whilst endeavouring to unlock value at its other prospective pegmatite and brine assets in Arizona, Nevada, and Pennsylvania. All of Bradda Head's licences are held on a 100% equity basis and are in close proximity to the required infrastructure. Bradda Head is quoted on the AIM of the London Stock Exchange with the ticker of BHL and on the TSX Venture Exchange with a ticker of BHLI.
