Bradda Head Lithium Ltd. announced that its halfway through its sonic drilling programme at its Wikieup asset in Central Arizona. Boart Longyear has extensive experience using sonic rigs and drilling in clay and in the United States. Sonic rigs are more environmentally sensitive compared to diamond rigs because they use less water, produce less waste and have superior recovery compared to reverse core (RC) drilling.

Bradda Head began the current Wikieup drilling programme in Fourth Quarter 2021 following the receipt of permission from the Bureau of Land Management (BLM), and is focussing on three areas at Wikieup where its geologists have identified highly prospective areas with the potential for lithium mineralised clay, similar to what is found at Arizona Lithium's Big Sandy project. Surface sampling has identified grades up to 1,750pm Li on its Wikieup project claims and Bradda Head recently expanded its landholding at Wikieup from 12.9km2 to 29.3km2 due its geologists' confidence in the prospectivity of the area. Bradda Head is now the largest landholder on the belt and is conducting a geophysical programme at all of its sedimentary assets over the next few months, which will help in planning of future drill programmes and add to its geological model of the Wikieup-Basin Lithium district.
