PORT OF SPAIN, TRINIDAD & TOBAGO and CALGARY, ALBERTA--(Marketwire - July 12, 2012) - Primera Energy Resources Ltd. ("PERL" or the "Corporation") (TSX VENTURE:PTT) is pleased to provide the following corporate update.

Moruga Exploration Update

Further to our previous press release announcing the Snowcap 1 well as "the first Trinidad onshore light oil discovery in 50 years, the Corporation in conjunction with the Operator shall commence long-term production testing from the Snowcap-1 well, subject to regulatory and partner approvals. The goal of the test is to determine sustained production rates and reservoir characteristics from prospective horizons encountered during drilling and which were previously tested. The shipping of oil, if any, from Snowcap-1 will be to an independent third party facility from where it will be treated and shipped to Petrotrin (the State owned Petroleum company). The trucking distance will be less than 30 kilometres. The Corporation will obtain WTI pricing for these sales volumes, less a discount to account for oil gravity, handling, processing and shipping. Gas produced during the test, if any, will be flared in accordance with the Ministry of Energy and Energy Affairs' regulations. The Corporation, in conjunction with the Operator, Parex Resources Inc., now expects to complete and test the Firecrown-1ST2 and Green Hermit-1 wells during the third quarter of 2012.

PERL's working and paying interest for the Moruga Block is 16.2%.
