CALGARY, ALBERTA--(Marketwire - April 19, 2011) -

NOT FOR DISTRIBUTION TO US NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Parex Resources Inc. ("Parex" or the "Company") (TSX VENTURE:PXT) an oil focused exploration and production company with operations in Colombia and Trinidad, is pleased to provide an update on the initial test results of the Company's Kona-2 well in Colombia. Parex' average working interest is 50 percent in its Colombia properties.

Kona-2 Gacheta Formation Test Rate of 2,634 Barrels per Day

Parex previously stated that a drilling rig had re-entered the Kona-2 well to drill out below the existing casing to re-drill the Gacheta Formation and prepare to complete this deeper zone. The Company previously reported log results of 20 net feet of potential oil pay in this formation.

On Sunday April 17, 2011 a swabbing unit became available on short notice and the Company commenced testing the Kona-2 well that had been previously perforated. After swabbing, at approximately 10:00 am MDT on April 17, 2011 the Kona-2 well began to flow naturally. After 38 hours, the final flow rate was approximately 3,045 barrels of fluid per day, comprised of 2,634 barrels of 32 degree API oil per day ("bopd") (net 1,317 bopd) and approximately 411 barrels of water per day. The well is currently shut-in to allow measurement of the down-hole pressure prior to completion of the short-term test.

The Company expects Kona-2 to be tied-in and on production by the end of April 2011.

As stated in the Company's press release dated April 15, 2011, based on test results or log analysis of Kona-1, Kona-2, Kona-3, Kona-4 and Supremo-1 and after the commissioning of the Kona oil treatment plant and completing the water disposal wells, Parex expects production of approximately gross 4,000-6,000 bopd (net 2,000-3,000 bopd).
