Parex Operational Update

Parex Operational Update: Q1 Production 26,700 bopd and Plans for Drilling Activity Increase in 2015

Parex Resources Inc. (“Parex” or the “Company“) (PXT.TO), provides an operational update that confirms Q1 2015 production of 26,700 bopd and announces the start of its 2015 exploration program. All amounts herein are in United States dollars (USD).

Exploration & Production Update:

• Oil production for Q1 2015 averaged approximately 26,700 barrels of oil per day (“bopd”), exceeding our original 2015 fully year production guidance of 26,500 bopd.
• Block LLA-34 Tilo-1: On March 28, 2015 Tilo-1 commenced a long-term test and current production is approximately 850 bopd.
• Commencement of 2015 Exploration Program: Block LLA-26 Rumba-1 exploration well was spud on March 25, 2015. The well is targeted to drill to a total depth of approximately 13,800 feet to test the Mirador and Une formations.
• Plan to increase the 2015 exploration drilling program by 2 additional exploration wells on Block LLA-32 and 1 contingent appraisal well for a total of 11 wells in 2015.

2015 Capital Plans: Brent Oil Price Scenario $50-$60 per barrel

Parex has a robust asset portfolio that provides capital allocation flexibility together with capital preservation. Within a Brent oil price scenario of $50-$60 per barrel, our current 2015 capital and production guidance is as follows:

1. Base Production (excluding 2015 Exploration): 26,500-26,700 bopd
2. Base + Exploration Capital: $145-$155 million

Supported by sustained production and an improving cost structure, Parex is seeking partner and regulatory approval to drill up to 3 additional wells on Block LLA-32 in 2015, in addition to our existing 8 exploratory commitment wells on 7 blocks for a total of 11 exploration and appraisal wells.

Further, as a result of a 15-20% reduction in capital costs over 2014, Parex expects to increase its exploration drilling program by the 3 wells while maintaining its original capital budget range of $145-$155 million. Dependant on exploration results, Parex will evaluate deploying additional non-budgeted capital to increase 2015 production.
