What is the pH of your waters? Do you think the stability of the Li minerals are sensitive to changes in pH?
It's very much neutral from the several samples we have so far. Lithium minerals (aluminosilicates and phylosilicates) dissolve under acidic conditions, so that needs to be taken into consideration when studying other sites.

Have you explored the possibility of contribution of groundwater circulating deeper in the crust contributing water with Na-Cl-SO4 type waters for your groundwater with different major ion chemistries?
Groundwater sampling is hopefully going to take place soon, as this deposit has several old mining (tin and tungsten) tunnels that run through the deposits. We are hoping to gain access to the underground parts of those tunnels from the mining company currently exploring the lithium potential of this site, as there are many pools of water hopefully equilibrated with the surrounding rocks that could show more interesting results.

Thanks for the presentation. Have you considered potential phytotoxicity of lithium? Natural waters are likely not an issue but drainage from mine sites could become problematic.
I have! Lithium is relatively bioavailable and plants do uptake it, but little is known on its effects. The lithium values we are seeing are likely not going to be toxic to plants, but the fluoride could be. Plants are very sensitive to higher fluoride concentrations. As we do more work and collect more data from other deposits, we may have some general idea of what the overall situation might be.
