Table 3 provides an estimate of the oil, associated gas, gas condensate and solution gas resources in all the reservoirs included in this latest Sproule audit. The Baran and Qulijan prospects are considered to be promising step out exploration locations to be drilled following success at the Kurdamir-2 well. The deeper reservoirs at the Sarqala prospect will likely be pursued in subsequent appraisal wells following the successful completion of the Sarqala-1 re-entry well which will test the Jeribe reservoir. Tables 1 and 2, as previously disclosed in the Company's Material Change Report dated January 17, 2011, are also provided, herein, to indicate the cumulative total of Contingent and Prospective Resources for Block K44 to date.
The location of the Qulijan, Baran and Sarqala prospects in Block K44 are as indicated in the map located at the following link: http://media3.marketwire.com/docs/wzr_map.jpg
The Company continues to assess the potential of other additional prospects and will continue to release audited results as they become available.
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.
Block K44 consists of approximately 2,120 square kilometres of land. WesternZagros holds a 40 per cent working interest in Block K44 pursuant to a Production Sharing Contract ("PSC") with the Kurdistan Regional Government signed on February 28, 2008. Additional information concerning the terms of the PSC can be found in the Corporation's Annual Information Form dated March 25, 2010, which is available at www.sedar.com.

Notes to Tables 1, 2, and 3:
(1) The contingent resources are the gross volumes estimated for the
Tertiary Oligocene carbonate reservoirs at Kurdamir-1, without any
adjustments for working interest or encumbrances.
(2) Contingent Resources are those quantities of petroleum estimated, as
of a given date, to be potentially recoverable from known accumulations
using established technology or technology under development, but which
are not currently considered to be commercially recoverable due to one
or more contingencies. Contingent resources have an associated chance
of development (economic, regulatory, market and facility, corporate
commitment or political risks). These estimates have not been risked
for the chance of development. There is no certainty that the
contingent resources will be developed and, if they are 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
contingent resources. The Corporation's Material Change report dated
December 16, 2010, which is available at www.sedar.com, contains
additional detail on the specific contingencies which prevent the
classficiation of these contingent resources as reserves.
(3) 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. 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.
(4) The gross unrisked contingent resources for gas reflect reductions for
condensate recovery, surface losses, and fuel gas.
(5) The contingent and 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
(6) 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.
(7) 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.
(8) 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.
(9) Mean Estimate is the average from the probabilistic assessment.
(10) The prospective resource estimates for the Qulijan Oligocene, Eocene
and Cretaceous, Baran Oligocene and Eocene, and Sarqala Oligocene,
Eocene and Cretaceous prospects are based upon interpretation of
WesternZagros' recent vintage 2D seismic database within Block K44
(1483 kilometres, 42 lines)and well data from WesternZagros'
Kuramir-1 and Sarqala-1 wells.
(11) The Qulijan Oligocene, Eocene and Cretaceous prospective resource
assessment is based on eight 2D seismic lines and offsetting
Kurdamir-1 well information.
(12) The Baran Oligocene and Eocene prospective resource assessment is
based on nine 2D seismic lines and nearby Kurdamir-1 well information.
(13) The Sarqala Oligocene, Eocene and Cretaceous prospective resource
assessment is based on seven 2D seismic and information from the
Sarqala-1 well drilled in 2008-2009.
(14) Barrels of oil equivalent (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.
WesternZagros has no plans to develop the gas and/or condensate and/or oil resources at this time. There is limited local infrastructure and markets for natural gas and condensate in the area at this time, and export infrastructure for natural gas to gain access to international markets has not yet been developed. Beyond this contingency, no federal Iraq legislation has been agreed to or enacted to address the future organization of Iraq's petroleum industry or the sharing of petroleum and other revenues within Iraq. Failure to enact legislation (or the enactment of federal legislation contradictory to Kurdistan Region legislation) could materially adversely impact WesternZagros' interest in the Kurdistan Region and the Production Sharing Contract (PSC).
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.
