Bradda Head Lithium (LSE:BHL) has announced encouraging surface sampling results from its Whistlejacket spodumene project in Arizona, where assays returned grades of up to 3.03% Li2O. Of the 60 rock samples collected, 18 recorded lithium oxide grades above 0.59% Li2O, highlighting extensive lithium mineralisation within low-iron, spodumene-rich pegmatites.
The results support the potential of the Whistlejacket project and provide further evidence of significant lithium-bearing zones across the property. Bradda plans to undertake additional surface and channel sampling programmes aimed at refining future drill targets and advancing exploration efforts ahead of a planned drilling campaign in 2026.
To support the next phase of development, the company has established a technical committee alongside Kennecott Exploration, a subsidiary of Rio Tinto. The committee will oversee exploration activities and contribute technical expertise as Bradda progresses its Arizona lithium assets.
Management believes the latest findings, together with the identification of several new high-priority exploration targets, point to substantial growth potential across its Arizona portfolio. The company noted that some historical drilling may not have fully tested the principal mineralised zones, creating opportunities for further discoveries.
Bradda is also continuing to emphasise responsible project development through environmental, social and governance initiatives, community engagement programmes and the use of local contractors. Combined with existing infrastructure and technical collaboration, these efforts are intended to reduce development risk and strengthen the strategic importance of the company’s assets within the U.S. critical minerals supply chain.
