WesternZagros Increases Prospective Resources to 3.5 Billion BOE's

CALGARY, ALBERTA--(Marketwire - July 20, 2011) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISSEMINATION IN THE UNITED STATES

WesternZagros Resources Ltd. (TSX VENTURE:WZR) ("WesternZagros" or "the Company") reports an increase of over 100 per cent in the combined mean estimate of gross unrisked prospective resources on the Company's Kalar-Bawanoor exploration block ("Block K44") to 2,192 million barrels of oil, or 3,570 million barrels of oil equivalent when oil, gas and condensate prospective resources are included (previously these estimates were 1,092 million barrels of oil, or 1771 million barrels of oil equivalent).

This latest independent audit by Sproule International Limited ("Sproule") addressed the multiple reservoirs in additional prospective areas of the Company's block, which are all located on the Garmian contract area to be covered by the amendments negotiated by WesternZagros, the Ministry of Natural Resources of the Kurdistan Regional Government ("KRG")and a wholly-owned subsidiary of Talisman Energy Inc. These amendments are awaiting approval by Oil and Gas Council of the KRG. The audit included prospects identified with Jeribe, Mio-Oligocene, Shiranish and Eocene reservoirs and two Upper Fars plays. These prospects and plays are potential follow on exploration locations for future drilling consideration. The Company continues to assess the potential of other additional prospects and plays and will continue to release audited results as they become available.

"After this fourth in the series of independently audited assessments, we're encouraged by the continuing rise in resource estimates. The recent oil discovery in the Jeribe Formation at the Sarqala-1 well and the potential in the Upper Fars reservoir at the Mil Qasim-1 well supports the prospectivity of these additional prospects and plays," said Simon Hatfield, WesternZagros' Chief Executive Officer.

Work is continuing on the Sarqala Jeribe contingent resource assessment and remaining prospective resource assessment and will be finalized upon receipt of final test fluid, engineering studies and detailed petrophysical analysis. Preparations are currently underway to secure and install the necessary equipment to undertake an extended test of the Sarqala-1 well. This includes establishing a crude storage and loading facility to permit the transfer and sale of produced oil.

WesternZagros has moved the 2,000 horsepower Viking I-10 rig to the Mil Qasim-1 site and is currently completing the necessary rig up and preparations for drilling operations to evaluate the Upper Fars reservoir. The anticipated spud date for Mil Qasim-1 is now early August, with test results expected in the fourth quarter of 2011. Success at the Mil Qasim-1 Upper Fars reservoir, combined with the results of the extended well testing planned for the Sarqala-1 Jeribe reservoir, will assist to determine the optimum location and timing for future exploration and appraisal activities required to unlock the potential of these most recently audited prospects and plays.

Sproule carried out its independent audit in accordance with the current guidelines outlined in the Canadian Oil and Gas Evaluation Handbook ("COGE Handbook") and in accordance with National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). Pursuant to the COGE Handbook, an audit is the process whereby an independent qualified reserves auditor carries out procedures designed to allow the auditor to provide reasonable assurance that a reporting issuer's reserves data (or specific parts thereof) have, in all material respects, been determined and presented in accordance with the COGE Handbook and are, therefore, free of material misstatement.

Table 1, below, provides summary estimates of the oil, and oil equivalent resources in all of the reservoirs included in this latest Sproule audit. A detailed table providing estimates of the gross unrisked prospective oil, associated gas, gas condensate and solution gas resources in all of the reservoirs included in this latest Sproule audit is disclosed in the Company's Material Change Report dated July 19, 2011 which is available at www.sedar.com.

Table 2 provides the cumulative total mean estimate of gross unrisked prospective resources for Block K44 to date, including estimates as previously disclosed in the Company's Material Change Reports dated December 16, 2010, January 17 and February 22, 2011, which are available at www.sedar.com.

Notes to Tables 1 and 2

1.  The prospective resources are the undiscovered potentially recoverable
    gross volumes estimated for the indicated reservoirs, without any
    adjustments for working interest or encumbrances. Prospective resources
    are those quantities of petroleum estimated, as of a given date, to be
    potentially recoverable from undiscovered accumulations by application
    of future development projects. Prospective resources have both an
    associated chance of discovery (geological chance of success) and a
    chance of development (economic, regulatory, market and facility,
    corporate commitment or political risks). The chance of commerciality is
    the product of these two risk components. The estimates contained herein
    have not been risked for chance of discovery or chance of development.
    There is no certainty that any portion of the prospective resources will
    be discovered. If a discovery is made, there is no certainty that it
    will be developed or, if it is developed, there is no certainty as to
    the timing of such development or that it will be commercially viable to
    produce any portion of the prospective resources. In this case,
    prospective resources are undiscovered resources that indicate
    development potential in the event the discovery is commercial and
    should not be construed as reserves or contingent resources. 

2.  The prospective resources for the Tertiary Oligocene carbonate reservoir
    at the Kurdamir-1 well are as at December 14, 2010, as previously
    disclosed in the Corporation's Material Change Report dated December 16,
    2010, which is available at www.sedar.com. The prospective resources for
    the Tertiary Eocene and Cretaceous carbonate reservoirs at the Kurdamir-
    1 well, the Upper Fars reservoir at Mil Qasim, and the Jeribe reservoir
    at the Sarqala-1 well are as at January 14, 2011, as previously
    disclosed in the Corporation's Material Change Report dated January 17,
    2011, which is available at www.sedar.com. The prospective resources for
    the Oligocene, Eocene, and Cretaceous reservoirs at Qulijan, the
    Oligocene and Eocene reservoirs at Baran and the Oligocene, Eocene and
    Cretaceous reservoirs at Sarqala in the Kalar-Bawanoor Block ("Block
    K44") are as at February 18, 2011, as previously disclosed in the
    Corporation's Material Change Report dated February 22, 2011, which is
    available at www.sedar.com. 

3.  Low Estimate is considered to be a conservative estimate of the quantity
    that will actually be recovered. It is likely that the actual remaining
    quantities recovered will exceed the low estimate. If probabilistic
    methods are used, there should be at least a 90 percent probability
    (P90) that the quantities actually recovered will equal or exceed the
    low estimate. 

4.  Best Estimate is considered to be the best estimate of the quantity that
    will actually be recovered. It is equally likely that the actual
    remaining quantities recovered will be greater of less than the best
    estimate. If probabilistic methods are used, there should be at least a
    50 percent probability (P50) that the quantities actually recovered will
    equal or exceed the best estimate. 

5.  High Estimate is considered to be an optimistic estimate of the quantity
    that will actually be recovered. It is unlikely that the actual
    remaining quantities recovered will exceed the high estimate. If
    probabilistic methods are used, there should be at least a 10 percent
    probability (P10) that the quantities actually recovered will equal or
    exceed the high estimate. 

6.  Mean Estimate is the average from the probabilistic assessment. 

7.  Barrels of oil equivalent (BOEs) include oil, solution gas, associated
    gas and condensate. BOEs may be misleading, particularly if used in
    isolation. A BOE conversion ratio of 6 Mcf: 1 bbl has been used and is
    based on an energy equivalency conversion method primarily applicable at
    the burner tip and does not represent a value equivalency at the
    wellhead. 

This resource disclosure coincides with the filing on SEDAR at www.sedar.com of a material change report, which includes the following additional information: a further description of the information used in the assessment of prospective resources, the risks and level of uncertainty associated with the discovery and recovery of the resources, the risks and uncertainties relating to the development of any discovered resources, and the significant positive and negative factors relevant to the estimates.

WesternZagros holds a 40 percent working interest, the KRG holds a 20 percent working interest (the costs of which are carried by WesternZagros) and a wholly-owned subsidiary of Talisman Energy Inc. holds the remaining 40 percent working interest. Subsequent to March 31, 2011, the Company concluded negotiations with the Ministry of Natural Resources of the KRG and Talisman to amend the PSC that governs the Company's exploration activities in the Kalar-Bawanoor Block. Once approved, the amendments will divide the contract area of the PSC into two contract areas, each under a separate production sharing contract. The Company is awaiting formal approval of both the Kurdamir and Garmian PSC's from the Oil and Gas Council of the KRG and execution of the PSC's by the KRG. Additional information concerning the terms of the PSC and proposed amendments can be found in the Corporation's Annual Information Form dated April 13, 2011, which is available at www.sedar.com.

This news release contains certain forward-looking information relating, but not limited, to operational information, future drilling, testing and production plans and the timing associated therewith. Forward-looking information typically contains statements with words such as "anticipate", "estimate", "expect", "potential", "could", or similar words suggesting future outcomes. The Company cautions readers not to place undue reliance on forward-looking information as by its nature, it is based on current expectations regarding future events that involve a number of assumptions, inherent risks and uncertainties, which could cause actual results to differ materially from those anticipated by WesternZagros. In addition, the forward-looking information is made as of the date hereof, and the Company assumes no obligation to update or revise such to reflect new events or circumstances, except as required by law.

Forward-looking information is not based on historical facts but rather on management's current expectations and assumptions regarding, among other things, plans for and results of drilling activity, future capital and other expenditures (including the amount, nature and sources of funding thereof), continued political stability, timely receipt of any necessary government or regulatory approvals, and the timely receipt of any insurance proceeds due to the Company. Although the Company believes the expectations and assumptions reflected in such forward-looking information are reasonable, they may prove to be incorrect. Forward-looking information involves significant known and unknown risks and uncertainties. A number of factors could cause actual results to differ materially from those anticipated by WesternZagros including, but not limited to, risks associated with the oil and gas industry (e.g. operational risks in exploration; inherent uncertainties in interpreting geological data; changes in plans with respect to exploration or capital expenditures; interruptions in operations together with any associated insurance proceedings; the uncertainty of estimates and projections in relation to costs and expenses and health, safety and environmental risks), risks associated with resource estimates, the risk of commodity price and foreign exchange rate fluctuations, the uncertainty associated with negotiating with foreign governments and risk associated with international activity. For further information on WesternZagros and the risks associated with its business, please see the Company's Annual Information Form dated April 11, 2011, which is available on SEDAR at www.sedar.com.
