Additional High Grade Discoveries At San Domingo

Additional High Grade Discoveries At San Domingo

BRITISH VIRGIN ISLANDS – Bradda Head Lithium Ltd reported on the Phase 2 core drilling at San Domingo (SD), Arizona. This is the third and final set of assays released from the 18,950 feet (5,776m) programme, completed December 2, 2023 and focuses on the Morning Star and Morning Star South targets, located southwest of the Central Targets.

“As we reach the end of this current San Domingo drilling exploration program, our objectives have been met and indeed surpassed and, as a result our expectations heightened. It is worth reflecting that total drilled metres at SD, from both programs is only 13,076 meters, covering less than 1% of the total property. These were the first two drilling programmes of any note undertaken at this historic and road accessible lithium mining camp in the USA. In today’s world the return on investment in these two campaigns has been substantial and we will build on this as we move forward. In other words, when the Lithium market bounces back, as we believe it will, we will be ready to maximise value from our total Lithium Portfolio including of course San Domingo. The strategic location in the USA of our ‘ready to move forward projects’ should not be discounted.

Our portfolio of pegmatites are emerging as viable and potentially extractable near surface resources. The shallow and high-grade intercepts seen at Morning Star are very exciting and we look forward to building 3-D models that may lead to follow-up drilling later this year. The abundance of tantalum, tin, and beryllium are a bonus, potentially adding value to this maiden drill programme at Morning Star. The obvious LCT (lithium-caesium-tantalum geochemical signature, e.g., Kathleen Valley signature) style of mineralisation confirms our belief that we have a formidable district with massive upside potential. We have more 3D modeling to explore and, given what we have discovered to date, this could significantly change the way we examine not only Morning Star, but the rest of the San Domingo pegmatite trend within our 33km2 property.”

High grade lithium mineralisation found at intervals such as 4.14m at 2.07% Li2O at a depth of 54.56m in drill hole SD-DH23-104 and 5.40m of 1.70% Li2O at a depth of 31.39m in 093, both at the Morning Star pegmatites (all holes are abbreviated from SD-DH23-). Again, favoured coarse-grained spodumene crystals are observed as the dominant lithium mineral with minor amounts of lepidolite and montebrasite

Large, cohesive, and mostly vertical pegmatite bodies were verified at Morning Star, which were strongly zoned with massive quartz, fine-grained albite, and minor schorl as well as massive zones of potassium feldspar. Pathfinder elements of tin, tantalum (Ta2O5), and beryllium (BeO) are found to be highly anomalous in the drilling, such as 6.76m at 145ppm Sn in hole 100, 872ppm Ta2O5 with 0.23% BeO in drill hole SD-DH23-088 over 2.90m

Morning Star drill hole 088 contains high-grade Ta2O5 with an interval of 872ppm Ta2O5 ppm and anomalous tin over 2.90m at a depth of 39.26m and 477 Ta2O5 ppm over 5.34m at 75.74m depth. Lithium, plus the bonus of ore grade Ta2O5with discrete anomalous tin and BeO in the Morning Star drill holes in a shallow environment, bodes well for the potential of open cut mining.
