Bradda Head Lithium Ltd, the North America-focused lithium development group, has announced the results from surface channel samples at the San Domingo (SD) Project in central Arizona.

The results included 5.00 m of 2.33%, 4.10 m of 2.81%, and 4.00 m of 1.26% Li2O at the White Ridge Target and 5.30 m of 1.25% Li2O at Morning Star. These and other surface samples collected were designed to augment the Phase II, 2023 drilling programme, as well as determine that this technique can and will be applied to future surface exploration programmes planned in 3Q24.

Sample locations include: Morning Star, South Morning Star, White Ridge, and Midnight Owl.


  • A total of 77 samples were collected from strategic targets across the San Domingo project, with locations designed to supplement drill holes that contain lithium (spodumene) mineralisation, particularly those that could result in mineable resources.
  • Some locations were chosen as a result of newly exposed spodumene bearing pegmatites at new drill sites.
  • White Ridge channel samples correspond to drill hole SD-DH23-072, confirming continuity of spodumene rich pegmatite, indicates mineralisation is open to the north and at depth.
  • Channel samples at Morning Star drill site SD-DH23-090 cut, 5.30 m at 1.25% Li2O, clearly connect and add confidence in continuity, building on resource potential.
  • The channel samples at Midnight Owl likely connect to drill hole SD-DH23-049 which had an intercept of 6.35 m @ 0.83% Li2O and 3.05 m of 1.03%, a distance of 55 m from surface.
  • The company is capitalising on surface lithium mineralisation exposures through channel sample techniques and by connecting to drill holes; this continues to demonstrate open cut potential and in part, will drive the next exploration programme.

Ian Stalker, Executive Chair, commented:

“We are highly encouraged by the surface channel samples taken at our San Domingo Project, which was designed to test multiple sample locations and provide further data that can be integrated into our planned work programme whilst targeting resource development. We believe that these high-grade samples bode extremely well for the potential of the asset in its entirety, and reaffirms favourable results from both previous sampling undertaken by Bradda, as well as the historic sampling.

Looking forward, the success of this cost-effective and efficient technique is also a notable positive, particularly as we look to further our surface exploration in 3Q24. This demonstrates our innovative thinking in regard to how to best maximise our resources, and so far, we are having great success.”
