Bradda Head Lithium announce completion of first hole at San Domingo

Highlights:

• The first hole has been completed of Bradda’s 7000 m drill programme, with multiple different pegmatite bodies intersected across the 262 m of core, including a 13 m pegmatite intercept.
• Visible lithium-bearing minerals identified include spodumene and lepidolite. To confirm, mineralogy X-ray diffraction (XRD) was carried out on eight samples from the intersections, identifying spodumene and lepidolite in all. Full assays are in progress and will be reported when received for this hole.
• The total programme will consist of 30 holes (7000 m) of diamond core drilling, and Bradda expects the total drilling component to be finished in 4Q22.
• Drilling was due to start in late July, but, due to extreme seasonal rains in Arizona, commencement of drilling was pushed back. Intermittent extreme rain has also occurred over August, delaying the completion of this first hole, but drilling will be more consistent in September onwards, after the monsoon season is over. The team will add a night shift which will expedite progress.
• The commencement of drilling follows positive results from a recent SRK 3D mapping exercise, increasing potential pegmatite outcrops by 190%, and following this Bradda increased its staked claims at San Domingo by 75%.
• These drill results strengthen Bradda’s geological team’s thesis that the Company’s pegmatite district may have larger structures at depth, based on all work undertaken to date including; surface sampling, channel sampling, geophysics, remote sensing and 3D modelling by Bradda and SRK geologists.
• Alongside the drilling, a follow-up field observation, soil sampling, and channel sampling programme is now underway across the full 23 km² San Domingo project landholding.

Charles FitzRoy, CEO of Bradda Head, commented:

“The completion of the first hole is an important milestone, signifying that we are continuing with our stated intent at San Domingo, following some really positive 3D mapping earlier this month, and it’s great to have now begun drilling at the fourth asset in our Arizona and Nevada portfolio, with visible spodumene intersected at multiple depths in the first hole.

“Our San Domingo pegmatite district is extensive, having been historically mined for lithium-in-spodumene in the 1940s and 1950s, within our permitted license area. Historical records show that the average reported grade of the spodumene mined during this period was 740 t at 2.75% Li20. Our claims now cover around 23 km².”

“Further surface fieldwork has added to our knowledge and strengthened our theory of the geological structures at depth at our San Domingo claims. The 3D mapping project combined with all fieldwork to date at San Domingo has helped in drillhole targeting and orientation, and the initial results from this first hole show that the build-up work has been on-trend, and these intersections in the first hole are extremely encouraging.

“Despite unavoidable delays due to Arizona’s recent wet season, we are very much on-track with our planned exploration timelines, and are looking forward to confirming our thesis that the San Domingo pegmatite district has larger structures at depth, similar to other zoned pegmatite systems, with the results to be reported in due course.”
