MENA Hydrocarbons Inc. ("MENA" or the "Company") (TSX VENTURE:MNH), on behalf of its 100% owned US subsidiary, Raven Wing Resources Inc., is pleased to release its September 1, 2011 National Instrument 51-101 compliant reserves and resource appraisal for its shallow light and medium oil project in NW Montana, and its Wasatch Plateau Gas Project in East-Central Utah. The report was prepared by the Colorado based independent qualified reserves evaluators Gustavson Associates as of October 7, 2011.


Highlights                                                                  

--  Net present value (discounted 10% before tax - forecast prices) of $38.1
    million ($0.17 per MENA share) attributed to its NW Montana proven +
    probable (2P) reserves. 
--  Net present value (discounted 10% before tax - forecast prices) of $16.7
    million ($0.07 per MENA share) attributed to its NW Montana proven (1P)
    reserves. 
--  Net present value (discounted 10% before tax - forecast prices) of
    $148.4 million ($0.66 per MENA share) attributed to its NW Montana
    proven + probable + possible (3P) reserves. 
--  In addition to the net 1P reserves of 0.4 MMbbl, net 2P reserves of 1.1
    MMbbl and net 3P reserves of 5.4 MMbbl assigned to MENA's Northwest
    Montana lands, Gustavson also assigned those same lands net prospective
    oil resources of 1.1 MMbbl (low estimate), 7.0 MMbbl (best estimate) and
    14.6 MMbbl (high estimate). 
--  In addition to MENA's Northwest Montana lands, Gustavson also evaluated
    MENA's Wasatch Plateau gas project located in East Central Utah and
    assigned those lands total net prospective gas resources of 50.7 Bcf
    (low estimate), 107.1 Bcf (best estimate) and 274.8 Bcf (high estimate).
    Gustavson characterizes this exploration project as low to moderate
    risk. 
--  With the assignment of these US based reserves, the total net present
    value (discounted 10% after tax-forecast prices) of MENA's company wide
    2P reserves (including MENA's Lagia, Egypt onshore heavy oil reserves as
    at May 18, 2011) is $53.5 million (or $0.24 per MENA share), and the net
    present value (discounted 10% after tax-forecast prices) of MENA's
    company wide 3P reserves is $163.2 million (or $0.72 per MENA share).

As a result of increased drilling activity in the areas surrounding MENA's US properties, and in connection with management's ongoing effort to maximize shareholder value, MENA engaged Gustavson to prepare an independent evaluation the Company's reserves and resources, as at September 1, 2011, for the Lewis and Clark Shallow Mississippian Oil Project located on the south dome of the Sweetgrass Arch located in the Pondera and Teton counties, Northwest Montana and the Southern Wasatch Plateau Gas Project located in East-Central Utah.

Commenting on the Gustavson report, Graham Lyon, MENA's President and Chief Executive Officer said "Even though the US is not the primary focus of MENA, our team has been working diligently over the last several months to ascertain the prospectivity and value of our existing US land base. We are very pleased with these results and will soon be evaluating the best way forward to unlock shareholder value from our US holdings."

The information below is derived from Gustavson's report dated October 7, 2011 and effective as of September 1, 2011. Gustavson's report was prepared in accordance with the standards contained in the Canadian Oil and Gas Evaluation Handbook (the "COGE Handbook") and utilizes the reserves definitions contained in National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). A copy of Gustavson's report is available at www.sedar.com under MENA's profile. All references to "$" in this news release mean the United States dollar.

The properties

The Lewis and Clark project area

The Lewis and Clark project area is located on the south dome of the Sweetgrass Arch in Pondera and Teton counties, Northwest Montana. The Lewis and Clark project area is located in an active petroleum-producing basin and is surrounded by numerous oil and gas fields with an extensive gathering and transport infrastructure. The prospect is centered on and adjacent to the existing Pondera Field that produces oil from porous carbonates of the Mississippian-age Sun River Dolomite - the same horizon targeted by the project. The Pondera field has produced over 26.7 MMBbl. Raven Wing Resources, a wholly-owned subsidiary of MENA, holds 6,242 gross acres (with an 81.2% average working interest) and has recently renewed all of its leases.

The Southern Wasatch Plateau Gas project area

The Southern Wasatch Plateau Gas project area is located in East-Central Utah. The primary target zones are Cretaceous (Turonian) sands and coals of the Ferron Sandstone Member. The Clear Creek Field is an established analog for the Ferron sandstone production and has produced approximately 138 Bcf as of August 2011. The Drunkard's Wash coalbed methane field is an analog for CBM targets and has produced 833 Bcf as of August 2011. Raven Wing Resources, a wholly-owned subsidiary of MENA, holds approximately 36,201 gross acres (with a 99.5% average working interest) prospective for both commercial gas sand and coal bed methane.

Notes to reserves tables:

1. Columns may not add due to rounding.

2. No heavy oil, natural gas or natural gas liquids reserves have been attributed to Raven Wing's properties.

3. "Reserves" are the estimated remaining quantities of oil and natural gas and related substances anticipated to be recoverable from known accumulations, as of a given date, based on: analysis of drilling, geological, geophysical and engineering data; the use of established technology; and specified economic conditions, which are generally accepted as being reasonable. Reserves are classified according to the degree of certainty associated with the estimates.

"Proved reserves" are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves. At least a 90% probability that the quantities actually recovered will equal or exceed the estimated proved reserves is the targeted level of certainty.

"Probable reserves" are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves. At least a 50% probability that the quantities actually recovered will equal or exceed the sum of the estimated proved plus probable reserves is the targeted level of certainty.

"Possible reserves" are those additional reserves that are less certain to be recovered than probable reserves. At least a 10% probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves is the targeted level of certainty.

"Undeveloped reserves" are those reserves expected to be recovered from known accumulations where a significant expenditure (for example, when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves classification (proved, probable) to which they are assigned.

Resource estimates for the Lewis and Clark and Southern Wasatch Plateau project areas

This news release contains estimates of prospective resources described above. 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 and a chance of development. Prospective resources are further subdivided in accordance with the level of certainty associated with recoverable estimates assuming their discovery and development and may be subclassified based on project maturity. There is no certainty that these prospective resources will be commercially viable to produce any portion of the resources. These estimates of resources are generally quoted as a range according to the level of confidence associated with the estimates. See below for further details.

Resources; uncertainty categories

Estimates of resources always involve uncertainty, and the degree of uncertainty can vary widely between accumulations/projects and over the life of a project. Consequently, estimates of resources are generally quoted as a range according to the level of confidence associated with the estimates. The range of uncertainty of estimated recoverable volumes may be represented by either deterministic scenarios or by a probability distribution. Resources are generally provided as low, best, and high estimates as follows:


--  "Low Estimate" - This 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. 
--  "Best Estimate" - This 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 or 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. 
--  "High Estimate" - This 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.
