De Grey Mining’s rock sampling discovers high grade lithium
Recent surface reconnaissance of rock chip samples with De Grey’s (ASX:DEG) 100% owned tenement at its Turner River Project has defined high grade lithium up to 4.22%.
Turner River (see map below) is located within a world class lithium-tantalum province, located just 40km from the Pilgangoora Lithium Tantalum Project, the $640 million Pilbara Minerals and 20km from its Tabba Tabba Tantalum mine, where recent drilling results yielded a peak result of 4.22% Li2O, and an average of 2.5%-0.15% Li2O.
A rock chip sampling programme was undertaken along a newly discovered 7.5km long zone of relatively sparsely outcropping pegmatites and found the area prospective for Lithium-Caesium-Tantalum (LST) style pegmatite hosted mineralisation.
Anomalous rock chip results include:
- Tantalum Pentoxide (Ta205) to 221.6ppm
- Caesium (Cs) to 1605ppm
- Niobium (Nb) to 146ppm
- Rubidium (Rb) to 8420ppm (0.84%)
- Beryllium (Be) to 23800ppm (2.38%)
Results look to be better than Pilbara Minerals Ta205 which sits at 138ppm.
Of course this sampling is still in its early stages and there is a long way to go before results become fully clear. If considering DEG for your portfolio take all external information into account and seek professional financial advice.
