We have considered the possibility for modeling of remarkable spectral feature 6708 Å for HD101065 (Przybylski's star) in two ways - as a blend of Li and REE lines and as blend of REE lines only. We show by model calculations that Li lines absorb significantly in the range 6707.72-6708.02 ÅÅ and resulting Li abundance 3.3 dex (in the scale lg N(H)=12.0) is near to the primordial value.
