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 agreed with China National Offshore Oil Corp. ("CNOOC") that it will enter the next and second phase of exploration commitment under the Petroleum Contract for Block 33/07 ("Petroleum Contract").

This decision follows the completion of Primeline's evaluation of the 2015 programme which saw a cost effective and smooth drilling operation of two exploration wells - LS23-1-1 and LS30-3-1. Both wells encountered very good sandstone reservoirs as predicted and gas shows, but were not commercial.

By entering into phase two, Primeline has agreed to relinquish 25% of the contract area under the Petroleum Contract. The contract area for Block 33/07 is 4,397 sq km.

Block 33/07 surrounds Block 25/34 where the LS36-1 gasfield is located. Any discovery from Block 33/07 can enjoy the benefit of LS 36-1 production facility which has been in production since July 2014.

Further details on upcoming exploration plans will be provided in due course.
