LS36-1 Gas Development EIA Approved by Government

NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE U.S.

Primeline Energy Holdings Inc. ("Primeline" or the "Company") (TSX VENTURE:PEH)
today announced that Primeline and CNOOC Ltd. ("CNOOC") have received formal
approval of the environmental impact assessment report ("EIA") relating to the
development of the LS36-1 gas field ("the Development") from the State Oceanic
Administration ("SOA").


The SOA had previously approved the routing of pipeline for the Development. The
Safety Assessment and Occupational Hazard Assessment of the Development have
also been approved by relevant government departments. 


The EIA approval paves the way for the final regulatory approval required for
the Development, namely approval of the Overall Development Program ("ODP").
Primeline expects that CNOOC will submit the ODP for confirmation by the
National Reform and Development Committee shortly and Primeline will make a
separate announcement when such submission is made.


In the meantime, CNOOC, as the Development Operator, has stepped up preparation
work on the Development. Major construction contracts have been signed and
fabrication of the platform and work on the pipeline are proceeding smoothly.
The Development is currently on schedule for first production expected to be
around Q3 2013.

Forward-Looking Statements 

Some of the statements in this news release contain forward-looking information,
which involves inherent risk and uncertainty affecting the business of
Primeline. These statements relate to the receipt of final regulatory approval
for the Development, and first production from the LS36-1 gas field. Actual
results may vary from those anticipated in such statements. Final regulatory
approval may be received later than anticipated, or not at all. Gas may first be
produced from the field at a later date, or not at all. If regulatory approval
is delayed or ultimately not obtained, or gas is produced later than expected or
is not produced, revenues from the sale of such gas may be realized later than
presently anticipated, or not realized at all. Exploration for oil and gas is
subject to the inherent risk that it will not result in a commercial discovery.
