Isn't muscovite a better indicator for potential Li bearing pegmatites? Seems to be muscovites in most holes.

I traded KGD before, made some cash but went back in again now losing, less than break even. Nut sure if keep into results or not. Most likely they wont find anything, I know it's a punt

"Muscovite is an effective indicator mineral for identifying prospective Li-bearing pegmatites.
However, multiple muscovite samples are required with both field and laboratory techniques as
there is an overlap of Li concentrations between prospective and non-prospective dikes.
Muscovite is also useful for identifying dikes with potential for rare metals Nb and Ta. This is
very useful as columbite group minerals are typically very fine-grained and difficult to identify in
the field.
The field portable Raman spectrometer, while useful for mineral identification, was not able to
detect a significant Li signature at the concentrations tested (1500-6000ppm). The use of
portable LIBS to detect Li contents within muscovite is a promising technique. It is currently
being used successfully in Australia to map the Li concentrations of spodumene in pegmatites.
The use of field portable techniques and real-time results in exploration will provide geologists
with a powerful tool for more effective drilling and field exploration. "
