HONG KONG, CHINA--(Marketwired - Oct. 28, 2015) -

NOT FOR DISTRIBUTION TO U.S. NEWS WIRES SERVICES, OR DISSEMINATION IN THE UNITED STATES

Primeline Energy Holdings Inc. ("Primeline" or the "Company") (TSX VENTURE:PEH) today announces that it has completed the drilling operations of the LS23-1-1 well and will now continue with the exploration drilling programme for the LS30-3-1 well.

The LS23-1-1 well was spudded on September 23 and reached total depth (TD) of 2,666m on October 21, 2015 and wireline logging data was subsequently acquired. The well encountered sandstone units of Paleocene and early Cretaceous age, drilling through the geological sequence as anticipated and finished in basement rock. It discovered several zones of gas bearing sandstone and evaluation of logging data indicated total cumulative net pay thickness of 14 metres. The LS23-1 prospect is a technical discovery of hydrocarbon but not likely to be a commercial discovery. Therefore Primeline has plugged and abandoned the well and will proceed with the drilling of the LS30-3-1 well on the basis of the agreed two well work programme.

LS30-3-1 is located approximately 20km north of the LS36-1 gasfield platform and is targeting a large channel sand prospect. The prospect was originally mapped in 2009/2010 and refined during the 2014/2015 evaluation. The planned TD of the well is 1,800m, targeting the same reservoir as that of the LS36-1 gasfield.

The drilling rig HYSY941 is currently conducting the final operations for the LS23-1-1 well. Once completed, Primeline's contractor China Oilfield Service Ltd plans to mobilise the rig to the LS30-3-1 location subject to weather and sea conditions, allowance for necessary equipment maintenance and preparation and approval of the operation licence. A separate announcement will be made when the drilling operation of LS30-3-1 commences.

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 Primeline's expectation that it will commence drilling of the LS 30-3-1 well soon. They are based on assumptions (among other things) that Primeline will obtain an operating licence for the LS 30-3-1 well, and that weather and sea conditions will be favourable for drilling. Although management believes these assumptions to be reasonable, actual results may vary from those anticipated in such statements. Issue of the operating license may be delayed or not obtained. Weather and sea conditions may change. Exploration for oil and gas is subject to the inherent risk that it will not result in a commercial discovery.
