("Caspian Sunrise" or the "Company")

BNG operational update

Introduction

The Company is pleased to announce that an initial evaluation of the third core sample taken from Deep Well A8 shows it to contain the same signs of secondary porosity and oil staining as with the first two samples.

The third core sample was 18 meters in length, starting at a depth of 4,379 meters and ending at 4,397 meters. With the first sample starting at a depth of 4,346 meters the total interval so far proved is now 51 meters.

Rather than to continue to delay the completion of the well we intend to resume drilling until the mudlogs indicate we are approaching the end of the oil-bearing interval, at which time we will conduct a further core sample to prove its total extent.

Ends.
