Ann: Numerous Pegmatites Discovered During Surface Exploration, page-15

They haven't mentioned Lepidolite or Mica just that its showing characteristics prospective for Lithium mineralisation.

They have mentioned 'muscovite'. The below excerpt is from geoconvemtion.com and in a nutshell explains its potentialities. Still early days but very promising given still 70% of the project yet to be traversed and sampled....let alone drilled.

Conclusions
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.
