About Bradda Head Lithium Ltd.

Bradda Head Lithium Ltd. is a North America-focused lithium development group. The Company currently has interests in a variety of projects, the most advanced of which are in Central and Western Arizona: The Basin Project (Basin East Project and Basin West Project) and the San Domingo Project.

The Basin East Project has a Measured Mineral Resource of 20 Mt at an average grade of 929 ppm Li for a total of 99 kt LCE and 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 for a total of 2.81 Mt LCE (https://www.accesswire.com/883697/bradda-head-lithium-ltd-announces-updated-mineral-resource-expansion-basin-project). A plan of operation was approved by BLM in 2025 for the Basin West area. Now company is working on an Environmental Assessment (EA) permit.

The San Domingo Project comprises 248 claims covering approximately 1850 acres, located primarily on BLM land, along with two Arizona State Land Department claims. To date, 108 drill holes totaling 13,089 m of core drilling have been completed across three drilling campaigns. The project area hosts more than 1,000 mapped pegmatites, of which 18 have been identified as priority targets, with six tested by drilling. The area currently holds two active Notices of Intent (NOI) permits, and updated drilling plans are in place that can be implemented once all required permits for the pegmatite targets are secured. The objective of the next exploration phase is to further delineate the most prospective areas and advance them toward potential Mineral Resource Estimation (MRE) and NI 43-101 compliant reporting.

The Whistlejacket Project comprises nine Arizona State Land Department Mineral Exploration Permits (MEPs), covering a total of 4,486.07 hectares. The project is subject to a definitive Option to Joint Venture agreement with Kennecott Exploration Company (KEX) and targets spodumene-bearing pegmatites. KEX previous Exploration include 19 drilled diamond drill holes totaling 4,188 meters, with all holes intersecting lithium mineralization. Notable results include 51.0 meters at 1.11% Li₂O in hole WSTL0009 and 19.47 meters at 1.66% Li₂O in hole WSTL0008. In addition, the project has benefited from extensive surface mapping, sampling, airborne geophysics, and the acquisition of high-resolution aerial imagery, significantly enhancing the geological understanding and overall value of the asset.

The Group intends to continue to develop its three phase one projects in Arizona, whilst endeavoring to unlock value at its other prospective pegmatite and brine assets in Arizona, Nevada, and Pennsylvania.
