Parex Resources Inc. ("Parex" or the "Company") (TSX: PXT), provides an operational update.

Upcoming Work Program

Throughout September 2016, Parex expects to accelerate its drilling program, with rigs mobilizing to the following locations:

• Aguas Blancas (WI 50%): Civil works are underway as we prepare to mobilize a drilling rig to spud an appraisal well prior to the end of September 2016. We are also preparing a second pad for drilling and expect to drill a total of 6 appraisal wells in 2016.
• Block LLA-34 (WI 55%): Following up on the successful Jacana-5 exploration well (currently producing approximately 2,500 bopd), the drilling rig will move from the Tigana-4 development well to the Jacana-6 exploration well. The Jacana-6 well is programmed to evaluate the extent of the Guadalupe oil accumulation to the south-west.
• Playon Block (WI 50%): We are preparing to mobilize a drilling rig to spud an exploration well, Boranda-1, prior to the end of September 2016.
• Block LLA-32 (WI 70%): We are preparing to mobilize a drilling rig to spud an exploration well, Xorop-1, prior to the end of September 2016.
• Cerrero Block (WI 100%): The Katmandu Norte-2 exploration well was drilled and cased. Parex plans to complete and test Katmandu Norte-2 and begin a long-term test on Katmandu Norte-1 in order to evaluate the Gacheta/Une reservoir.

The following is a summary of the expected drilling activities for second half (H2) of 2016:
