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

Parex Resources Inc. ("Parex" or the "Company") (TSX:PXT), a company focused on oil exploration and production in Colombia and Trinidad, is pleased to announce that net working interest production has recently reached 11,000 barrels of oil per day ("bopd").

Recent Highlights (post September 12, 2011 press release):

• Signed a farm-in agreement to acquire 35 percent working interest on the El Eden Block in the Llanos Basin;
• Continued successful delineation of the Kona field with Kona-3 and Kona-10 brought on-stream at a total production rate of approximately 2,500 bopd;
• Signed a contract to import two modern and efficient drilling rigs to Trinidad, with anticipated drilling to begin prior to year end 2011; and
• Increased current production up to approximately 11,000 bopd.

Colombia Exploration Update

On September 23, 2011, Parex signed a farm-in agreement with Petroamerica Oil Corp. ("Petroamerica") for the El Eden Block ("Farm-in"), which is located south-west of Block LLA-16 in the Llanos Basin. The Farm-in excludes the Chiriguaro discovery area, and the Farm-in is subject to approval by the Colombian National Hydrocarbon Regulatory Authority ("ANH"). Under the terms of the Farm-in, Parex has paid US$ 3.5 million for reimbursement of prior 3-D seismic costs and will fund the first 65 percent of an exploratory commitment well to be spud before June 9, 2012 to earn 35 percent working interest in the block. Including this farm-in, since entering Colombia in 2009, Parex has increased it net acreage in excess of 650,000 acres.

For the remainder of 2011 on Block LLA-16 (Parex 100 percent working interest), Parex will continue appraisal and delineation activity at Kona, Kona Norte, Supremo and Sulawesi. Exploration wells scheduled to be spud prior to year end 2011 are Merida and Java. The Merida location has been built and lease construction has commenced on Java.

On blocks LLA-20, LLA-29, LLA-30 and LLA-57 (Parex 100 percent working interest), Parex has identified several prospects and has begun the regulatory process to allow for civil work and drilling to begin in early 2012. In addition, Parex plans to drill on El Eden and Los Ocarros blocks during 2012, subject to receiving ANH recognition of the two farm-in agreements.

Parex has initiated a large 3-D seismic program that will cover 75 square kilometres ("km²") on Block LLA-16, 135 km² on Block LLA-20, and 165 km² on Block LLA-57. At the completion of the seismic acquisition program, Parex will have approximately 60 percent of the Company's 814,000 gross acres in Colombia covered by 3-D seismic.

Colombia Operations Update

Current production is approximately 11,000 bopd. A summary of the Company's current operations is provided below:

Current Operations
Field/Well	Formation		Status
Kona-11	Mirador		Drilled. Casing
Kona Norte-2	Guadelupe		Drilled. Preparing to case for water disposal
Supremo-2	C7/Mirador		Drilled. Logging
Sulawesi-3	C7		Completing

Following Parex' last press release on September 12, 2011, the Company has drilled and completed the Kona-3 and Kona-10 wells, which have added approximately 2,500 bopd to production. The Kona 10 well was drilled as a Gacheta development well with the secondary objective of evaluating the Une formation. Well logs indicated oil pay in the Une Formation and the well subsequently tested light oil on natural flow at rates up to 1,000 bopd. Structural interpretation indicated a better up-dip location for production in the Une formation so the well was subsequently completed as a Gacheta production well. A Kona appraisal well targeting the Une formation will be included in the 2012 drilling program.

Approximately 1 kilometre north of the Kona field, Kona Norte-2 was drilled with the dual objectives of evaluating the Mirador Formation and adding a second water disposal well. The well logs and shows of oil during drilling indicated the potential for oil pay in the Mirador Formation and consequently Parex expects to spud Kona Norte-3 during November 2011 to test the Mirador Formation and evaluate other prospective formations including the C7, Gacheta and the Une. Operations are underway to case Kona Norte-2 as a water disposal well in the Guadelupe Formation. Until Kona Norte-2 is on-line, Kona field production may be restricted due to the water disposal constraints.

On September 5th, 2011 the Sulawesi-1 well commenced production at a rate of 1,300 bopd through a temporary, flow rate short-term restricted facility. Parex is currently installing a long-term test facility for the Sulawesi discovery. The Sulawesi-3 well was spud on August 29, 2011 as a follow-up appraisal well to the north of Sulawesi-1 to evaluate the C7 Formation and the drilling rig was released on September 30, 2011. Parex expects to commence completion and testing of Sulawesi-3 with a service rig by the end of October 2011. The Company intends to drill a third well into the prospect during the fourth quarter of 2011, to be coordinated with the facility expansion.

On October 9, 2011, Supremo-2 was spud to test the potential up-dip of the Supremo-1 well, which produced from the Mirador formation at facility restricted rates of 500 bopd and 2,000 barrels of water per day. Parex expects to have Supremo-2 test results by the end of December 2011.

Parex estimates that average production for the three months ending September, 2011 ("third quarter") was approximately 7,030 bopd and that September 2011 production averaged 7,990 bopd. During the third quarter Kona field oil production was restricted as a result of constrained water handling. Further, Parex expects that third quarter sales volumes will be lower than production volumes as a significant portion of Parex' September oil production was contracted at a Brent crude reference price and has been recorded as inventory until the volumes were exported from Colombia.

Trinidad Exploration Update

In order to accelerate Parex' ongoing onshore Trinidad exploration activity, the Company has signed a contract with Tuscany International Drilling Inc. to import to Trinidad two modern and fit for purpose drilling rigs. Rig 120 is a new build 850 horsepower dual purpose drilling and completion rig and Rig 110 is a one year old 1,500 horsepower drilling rig that is being moved from Guyana. Both rigs are currently being shipped to Trinidad and subject to receiving regulatory approvals, will begin operations prior to year end 2011. Parex expects that the two new rigs will be used to spud a second Central Range Block ("CRB") Shallow exploration well and drill the Firecrown side track well on the Moruga Block. The Company plans to spud its first CRB Deep well following drilling operations on the Moruga Block.

On the CRB Shallow (50 percent working interest), the Cribo-1 well was spud on July 22, 2011 and drilled to a target depth of approximately 6,000 feet using an existing onshore Trinidad rig. The rig was released September 25, 2011 and Parex expects a service rig to start completion and testing operations during November, 2011. The final CRB Shallow commitment well, Mapepire-1 is scheduled to be drilled by one of the new imported rigs.

In preparing for the 2012 exploration program, Parex has now received environmental permits for Snowcap-2 and a new prospect Green Hermit, both located on the Moruga Block.

2011 Guidance Confirmation

In Colombia, the Company plans to continuously operate with three drilling rigs and one service rig. For the remainder of 2011, Parex expects to deploy its drilling rigs to: the Kona field, Sulawesi/Supremo, and exploration. In addition, the Company expects to begin operating two drilling rigs in Trinidad. Parex reiterates its previous guidance that the 2011 light oil production exit rate is expected to be 14,000 bopd.
