Ann: Drilling Update, page-10

Looking at the SG and conductivity of the previous hole, we found 73 conductivity and 1.025SG to provide approx. 118 mg/L of lithium. assuming there's some linear relationship between brine and SG, interpolating these values we would looking at 150-200 mg/l of brine, which is low, but given that this appears to be a compromised area due to heat, I think this is still promising.
definitely not a duster since it confirms there's brine around. remember early days many were saying if we have 350mg/L + of brine in the first hole we'd be happy.
