KOREA Electric Power Corp says it has reached an agreement to buy the Bylong coalmine in NSW from Anglo American for $403 million(.95c per tonne)
The state-run Kepco will wholly own the Bylong mine, which has total indicated and inferred resources of 420 million tonnes of low-ash thermal coal, used for power generation, extractable by open-cut and underground mines.
Coalspur has 812m tonnes measured & indicated which is better than being inferred x .95c p/tonne = $771 million.
Current market cap is $286 million @ .79c
My calculations means that coalspur market cap should be 2.7 times it's current share price which = $2.13.
Can anyone correct me if my calculations are wrong?
