Bradda Head Lithium Ltd. announced an updated Mineral Resource estimate (MRE) at its Basin East (BE) Project in Arizona resulting in a 65% increase in contained lithium carbonate equivalent (LCE) tonnes. Furthermore, a continuous higher grade internal layer has been identified with a grade of c. 1,300ppm Li in the upper part of the deposit. SRK the highly regarded Independent geological consultants have also identified a 1Mt to 6Mt LCE Exploration Target within the Basin Project district held by Bradda Head.

Highlights: Based on only 1,110m of 2021 drilling at its Basin East claim in Arizona, Bradda Head has added 120 kt of LCE to the original maiden Mineral Resource which previously totalled 185 kt LCE, for an updated total LCE content of 305 kt. The recent exploration drilling, and core logging has also identified a High-Grade zone within the resource of 58 kt at c.1,300 ppm Li. This has significant benefit in identifying and locating the next round of drilling targets.

The 2021 drilling programme (3 out of the 10 holes were twinned holes) has given SRK greater confidence in the estimate at Basin East. The previous MRE was contained entirely within the Inferred Mineral Resource category and now c. 23% of the updated LCE content is in the Indicated Mineral Resource category. It's important to note that some 75% of the updated total LCE is in the Upper Clay which has a grade of c.850 ppm and c.20% of the updated total LCE sits within a newly defined High-Grade layer within the Upper Clay which has a grade of c.1,300ppm Li.

The High-Grade and Upper Clay zones thicken towards the northwest extent of the drilled area into BHLs Basin East Extension claim and could potentially form part of a higher-grade mining operation than previously planned. This could be mined early in the mine plan as the High-Grade zone sits in the upper part of the deposit. The previous drilled area only covered 1.9% (0.9km2) of Bradda's 47km2 of sedimentary claims. The 2021 drill programme has only increased this drilled area to 2.4% (1.1km2) of BHLs 47km2 of claims in this district.

Importantly for future resource growth, the Mineral Resource remains open to the west and northwest of the drilled area where BHL has the adjacent Basin East Extension (BEE) claim block and beyond into BHL's Basin North (BN), Basin West (BW) and Basin West Extension (BWE) claim blocks where geological mapping and geophysical surveys suggest that similar clay strata are present. On this basis, SRK has determined an Exploration Target of between 300 to 1,300 Mt of material grading between 600 to 850 ppm Li identified covering the claims BN, BE, BEE and BW and BWE. This target is equivalent to a range of between 1 to 6 Mt LCE.

An extensive 30-hole drilling programme is planned for the remainder of 2022 at BEE and BN with permits in the process of being obtained and should start in second quarter, also an additional 14-hole sonic drill programme has also been approved at BE.
