About Bradda Head Lithium Ltd.

Bradda Head Lithium Ltd is a North America-focused lithium development group. The Company's principal interests include the Basin Project, comprising Basin East and Basin West, and the San Domingo Project in Arizona.

The Basin East Project has a Measured Mineral Resource of 20 Mt at an average grade of 929 ppm Li, containing 99 kt LCE; an Indicated Mineral Resource of 122 Mt at an average grade of 860 ppm Li; and an Inferred Mineral Resource of 499 Mt at an average grade of 810 ppm Li. Together, these categories contain 2.81 Mt LCE. A plan of operations for the Basin West area was approved by the Bureau of Land Management in 2025, and the Company is progressing the associated Environmental Assessment.

The San Domingo Project comprises 248 claims covering approximately 1,850 acres, located primarily on Bureau of Land Management land, together with two Arizona State Land Department claims. To date, 108 drill holes totalling 13,089 m have been completed across three drilling campaigns. More than 1,000 pegmatites have been mapped across the project area; 18 have been identified as priority targets and six have been drill-tested. Two Notices of Intent are active, and updated drilling plans may be implemented once the required permits have been secured. The next exploration phase is intended to further delineate prospective areas and assess their potential to support a Mineral Resource Estimate prepared in accordance with NI 43-101.

The Whistlejacket Project comprises nine Arizona State Land Department Mineral Exploration Permits covering 2,010.7 hectares. The project is subject to a definitive option-to-joint-venture agreement with Kennecott Exploration Company and targets spodumene-bearing pegmatites. Kennecott's previous exploration included 19 diamond drill holes totalling 4,188 m, all of which intersected lithium mineralisation. Reported results include 51.0 m at 1.11% Li₂O in hole WSTL0009 and 19.47 m at 1.66% Li₂O in hole WSTL0008. Surface mapping, sampling, airborne geophysics and high-resolution aerial imagery have also contributed to the geological dataset for the project.

The Group intends to continue advancing its three principal projects in Arizona while seeking to realise value from its other prospective pegmatite and brine assets in Arizona, Nevada and Pennsylvania.
