Bradda Head Lithium Ltd. announced, as part of its fast-track development programme at its Arizonan sedimentary lithium assets, that it has engaged drilling contractor Boart Longyear for a sonic drilling programme at the Company's Wikieup Project, starting in early fourth quarter. Bradda Head has engaged world-renowned drilling contractor Boart Longyear to carry out a sonic drilling programme at the Company's Wikieup clay project in Western Arizona, which is adjacent to Hawkstone's Big Sandy resource of 32.5Mt at 1,850ppm Li. 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 core drilling, or RC.
