buy recommendation - deep value?

I see the latest weekly coal sector report from Wilson HTM continues to have CEY at a BUY recommendation with a very attractive NPV of $5.90 and target price of $5.43, that's a massive 60% premium to the current share price (!) and the biggest such premium of all the coal stocks they cover, including FLX, GCL, MCC, NHC, WHC.

So it seems to be only a matter of time before the secret gets out and CEY flies above $3.00. Any thoughts on why it remains so undervalued at present unlike most other stocks?
