Bradda Head announces resource expansion at Basin project

Highlights:

• Based on only 1200 m of majority infill and some expansion drilling (8 out of the 14 were infill, 6 were expansion) at its Basin East (BE) claim in Arizona, completed in 2022. Bradda Head has added 65 000 t of LCE to the mineral resource, for an updated total LCE content of 371 000 t.
• This exploration drilling has also expanded the Upper Clay zone within the resource by 11% to 55 million t at an average grade of 840 ppm Li, and revealed that mineralisation is also open to the north at BE as well as to the west and northwest as previously identified. This has significant benefit in identifying the next round of drilling targets for further resource expansion potential.
• The 2022 drilling programme has given the company greater confidence in the estimate at BE, and notes that indicated content of the MRE has increased by approximately 17%.
• It is important to note that some 67% of the updated total LCE (367 000 t LCE) is in the Upper Clay which has an average grade of approximately 840 ppm Li, this includes an internal High-Grade layer which has an average grade of 1380 ppm Li, some 5% higher than previously estimated.
• The High-Grade and Upper Clay zones thicken to the northwest extent of the drilled area towards Bradda's Basin East Extension (BEE) claim and could potentially form part of a phased mining operation. 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 1.1 km² of Bradda's 41 km² of sedimentary claims. The 2022 infill and expansion drill programme has increased this drilled area to 1.4 km² of BHL's claims in this district.
• Importantly for future resource growth, the mineral resource remains open to the west, northwest north of the drilled area where BHL has the adjacent 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 predict similar clay strata are present.
• An extensive 30-hole drilling programme is planned for 2023 at BEE and BN with permits received, and drilling is planned to start in 1Q23. Bradda is also permitting a 80-hole programme at BWE and BW where it expects significant resource growth stemming from geological work done to date by our geologists. BW and BWE cover an 11 km² area, which is considerably larger than the BE (1.5 km²), BEE (2.3 km²) and BN (2.3 km²).
