Bradda Head Lithium reports progress of Wikieup Sonic Drilling Programme

Global Mining Review,

Bradda Head Lithium Ltd (BHL) has announced that it is halfway through its sonic drilling programme at its Wikieup asset in Central Arizona.


  • Drilling contractor Boart Longyear has so far drilled 14 holes (1520 m) out of a planned total of 28 holes (2560 m).
  • After completion of this programme at Wikieup, BHL will have drilled on roughly 7 km2 of its ground, which is c.15% of the Company’s 47km2 of sedimentary claims in Arizona.
  • The drilling rate at Wikieup has been going approximately 3x faster than the 2021 Basin East programme at a rate of 31 m per 12-hour shift on average, compared to the 2021 BE programme at 11 m per 12-hour shift. The programme at Wikieup is also 3x larger than the Basin East 2021 programme.
  • Boart Longyear’s sonic drilling process is an environmentally sensitive option, using far less water and producing far less waste than traditional techniques.
  • The maiden resource from Wikiuep is on track to be released in 2Q22, and SRK are this week visiting Wikieup and Basin to complete technical verification of the work that is being carried out. The Basin resource update is expected this quarter, with final assays received in January 2022.

Charles FitzRoy, CEO of BHL, commented:

“We are delighted with the progress of the larger Wikieup drilling programme, which so far has shown to be more time-efficient than the Basin East programme, despite unavoidable staff shortages caused by the COVID-19 pandemic. This also reinforces our confidence in the work of Boart Longyear and the Bradda Head operations team on the ground in Arizona.

“The maiden resource from Wikieup is due in 2Q22 and will add to our growing resource numbers. The resource update from Basin East is due in 1Q22, and we expect the upgrade to be significantly larger than the current JORC resource of 185 kt of LCE.

“2022 has started very strongly for Bradda Head and we have a lot more to come including; resource update from Basin East in 1Q22, Wikieup maiden resource 2Q22, San Domingo drilling results in 3Q22, permitting and drilling at all our other sedimentary claims in 2Q22 – 4Q22 and initial drill programmes at Wilson and Eureka in 2H22. It’s going to be a big resource growth year for BHL.”
