1&2p reserves worth a$153++m , page-2

re: i dont get it 13million barrells 13,000,000 barrells in reserve x US$30/bbl = US$390,000,000.

Why do they say amu reserves are worth only US$89million?

Could someone please explain this too me, AMU do have 13million bbls reserve right?
as in they will be able to SELL all this oil bit by bit every year?
am i right, and 13million bbls x us$30 = us$390million.
or am i totally of the track with this?

So AMY is SERIOUSLY undervalued. at 48c.
