HOUSTON, TEXAS - December 4, 2012 (Investorideas.com energy newswire) EFL Overseas Inc. (
OTCBB:EFLO)
 is pleased to announce the acquisition of additional working interests 
in the Kotaneelee gas property and the results of independent reserves 
and resources evaluations (NI-51-101 compliant).
    
ACQUISITION
  Effective October 17, 2012, EFLO acquired a 30.664% interest in the
 Liard basin gas field and facilities located in the Kotaneelee Area, 
Yukon Territory, Canada (the "Assets") from Nahanni Energy Inc. and 
certain of its wholly owned subsidiaries ("Nahanni"). The Nahanni 
purchase follows EFLO's earlier acquisition of Devon Canada's interest 
(generally a working interest of 22.989%, with a working interest of 
69.337% in one gas well) in the Assets. Upon closing the Nahanni 
purchase, EFLO became the largest interest holder in the Kotaneelee with
 a general interest of 53.65% and a working interest of 100% in one gas 
well.
  "Our acquisition of the additional interest at Kotaneelee provides 
us with a controlling position in this exciting project", stated EFLO 
Chairman Henry Aldorf. "Increasing our working interest to approx. 54% 
allows us to drive forward development plans and offers our shareholders
 greater potential upside."
  "With the closing of the Nahanni acquisition, we are focused on 
actively pursuing additional interests at Kotaneelee and the surrounding
 area," added EFLO Chief Executive Officer Keith Macdonald. "The larger 
asset base will be helpful as we evaluate our future market 
opportunities in the Pacific Rim, North America and the Yukon."
 
  The Assets include 30,542 acres of land, a gas dehydration plant 
(capacity: 70 MMcf/d), one water disposal well (capacity: 6,000 bbls/d),
 one well temporarily shut-in for plant maintenance and two suspended 
gas wells, flarestack, storage tanks, airstrip, roads, gathering 
systems, geological 
data
, equipment, and other transportation and camp infrastructure.
  As consideration for the Assets, EFLO paid Nahanni US$132,600 in 
cash (representing closing consideration of Cdn$400,000 less certain 
pre-closing liabilities settled by EFLO), and 1,614,767 shares of one of
 its subsidiaries, which are exchangeable on a one-for-one basis for 
shares of EFLO's common stock (valued at Cdn$4,100,000; US$4,190,610). 
In addition, EFLO indemnified Nahanni against its portion of the 
abandonment, reclamation and environmental liabilities associated with 
the Assets. EFLO intends to undertake an active development and 
exploration program, which is expected to defer these potential 
liabilities into the future.
  EFLO continues to pursue the acquisition of additional working interests in the Assets.
  RESERVES
  The following reports certain pro forma reserve information, after 
giving effect to both the Devon and Nahanni acquisitions, based on an 
independent assessments by AJM Deloitte ("AJM") of dated effective June 
30, 2012 using forecast prices and costs (the "EFLO AJM Reserve 
Reports"). AJM prepared separate reports for the Devon and Nahanni 
acquired working interests. The numbers presented below reflect an 
aggregation of the two reports. The EFLO AJM Reserve Reports were 
prepared in accordance with definitions, standards and procedures 
contained in the Canadian Oil and Gas Evaluation Handbook ("COGE 
Handbook") and National Instrument 51-101 Standards of Disclosure for 
Oil and Gas Activities ("NI 51-101"). In addition reserve information 
required under NI 51-101 and effective for the EFLO's fiscal year ended 
August 31, 2012 will be included in NI 51-101 forms which will be filed 
in connection with EFLO's financial statements as at and for the year 
ended August 31, 2012. Such reserve information was filed on Sedar on 
November 29, 2012 and gives effect only to the Company's reserves 
resulting from the Devon acquisition, as the Nahanni acquisition 
occurred subsequent to August 31, 2012. The differences between Devon 
related reserves and net present values reported in the June 30 report 
and the August 31 report are not material.
  

  
  Gas prices for the report were based on delivery and sale at 
Station 2 in British Columbia. The EFLO AJM Reserve Reports base case 
forecast effective June 30, 2012 is as follows: 2012 - $2.00; 2013 - 
$2.95; 2014 - $3.55; 2015 - $3.95; 2016 - $4.35; 2017 - $4.80; 2018 - 
$5.35; 2019 - $5.80; 2020 - $6.50; and thereafter escalated at 2% per 
annum. Prices are in Canadian dollars per Mcf.
  SUMMARY OF RESOURCES
  The following reports certain pro forma resource information, based
 on an independent assessment by AJM dated effective June 30, 2012 using
 forecast prices and costs (the "EFLO AJM Resource Report"). The EFLO 
AJM Resource Report was prepared in accordance with definitions, 
standards and procedures contained in the COGE Handbook and NI 51-101.
  The AJM Resource report evanuated the resources on EFLO acreage on 
gross terms and did not consider working interest. AJM evaluated the 
lands to assess the resource potential for the Middle Devonian Shales 
designated as Lower Black Shale (Muskwa/Evie), Middle Shale (Fort 
Simpson), and Upper Shale (Kotcho/Exshaw) as well as the potential for 
expansion of resource for the Nahanni on the producing East Flank. The 
results are summarized as follows, adjusted by management to reflect 
EFLO's 53.65% interest in the evaluated lands after giving effect to the
 Devon and Nahanni acquisitions.

  The following represents the total for the low, best and high cases as evaluated for the Shales.
  

  
  In addition, AJM has evaluated a Nahanni prospect on the West Flank.
  

  
  NOTICE REGARDING PRESENTATION OF THE COMPANY''S RESERVE AND CONTINGENT RESOURCE INFORMATION
  The determination of reserves and resources involves the 
preparation of estimates that have an inherent degree of associated 
uncertainty. The estimation and classification of reserves and resources
 requires the application of professional judgment combined with 
geological and engineering knowledge to assess whether or not specific 
reserve or resource classification criteria have been satisfied. 
Knowledge of concepts including uncertainty and risk, probability, 
statistics and deterministic and probabilistic estimation methods is 
required to properly use and apply reserve and resource definitions.
  Disclosure in this document of reserves and resources is presented 
in accordance with Canadian securities laws. The United States 
Securities and Exchange Commission (the "SEC") generally permits U.S. 
reporting oil and gas companies, in their filings with the SEC, to 
disclose only proved, probable and possible reserves and production, net
 of royalties and interests of others. The Company uses certain terms in
 this document, such as resources or contingent resources that the SEC's
 rules would prohibit a U.S. company from including in filings with the 
SEC. The SEC generally does not permit U.S. companies to disclose net 
present value of future net revenue from reserves based on forecast 
prices and costs. Canadian securities laws permit, among other things, 
the presentation of certain categories of resources and the disclosure 
of production on a gross basis before deducting royalties. Unless noted 
otherwise, all disclosures of reserves and resources in this document 
are made on a gross basis using forecast price and cost assumptions.
  In this news release:
  "gross" means:
  (a) in relation to the Company's interest in production or reserves, its working interest share before deduction of royalties;
  (b) in relation to wells, the total number of wells in which the Company has an interest; and
  (c) in relation to properties, the total area of properties in which the Company has an interest.
  "net" means:
  (a) in relation to the Company's interest in production or 
reserves, its working interest share after deduction of royalty 
obligations;
  (b) in relation to the Company's interest in wells, the number of 
wells obtained by aggregating the Company's working interest in each of 
its gross wells; and
  (c) in relation to the Company's interest in a property, the total 
area of properties in which the Company has an interest multiplied by 
the working interest owned by the Company.
  All evaluations of future revenue are after the deduction of 
royalties, development costs, production costs and well abandonment 
costs but before consideration of indirect costs such as administrative,
 overhead and other miscellaneous expenses.
  Disclosure of Reserves
  The reserves estimates and related estimates of net present values 
presented in this document were prepared to comply with Canadian 
reserves disclosure standards and reserves definitions as set out in NI 
51-101 and the COGE Handbook prepared jointly by The Society of 
Petroleum Evaluation Engineers (Calgary Chapter) and the Canadian 
Institute of Mining, Metallurgy & Petroleum (Petroleum Society).
  Reserves are estimated remaining quantities of oil and natural gas 
and related substances anticipated to be recoverable from known 
accumulations, from a given date forward, 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;
 
- 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; and
 
- Possible reserves are those additional reserves that are less 
certain to be recovered than probable reserves. It is unlikely that the 
actual remaining quantities recovered will exceed the sum of the 
estimated proved plus probable plus possible reserves.
 
Each of the reserves categories (proved, probable and possible) may be divided into developed and undeveloped categories:
  
- Developed reserves are those reserves that are expected to be 
recovered from existing wells and installed facilities or, if facilities
 have not been installed, that would involve a low expenditure (for 
example, when compared to the cost of drilling a well) to put the 
reserves on production. The developed category may be subdivided into 
producing and non-producing.
 
- Developed producing reserves are those reserves that are expected 
to be recovered from completion intervals open at the time of the 
estimate. These reserves may be currently producing or, if shut-in, they
 must have previously been on production, and the date of resumption of 
production must be known with reasonable certainty.
 
- Developed non-producing reserves are those reserves that either 
have not been on production, or have previously been on production, but 
are shut-in, and the date of resumption of production is unknown.
 
- 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, possible) to which they are 
assigned.
 
In multi-well pools it may be appropriate to allocate total pool 
reserves between the developed and undeveloped categories or to 
subdivide the developed reserves for the pool between developed 
producing and developed non-producing. This allocation should be based 
on the estimator's assessment as to the reserves that will be recovered 
from specific wells, facilities and completion intervals in the pool and
 their respective development and production status.
  The qualitative certainty levels referred to in the definitions 
above are applicable to individual reserves entities (which refers to 
the lowest level at which reserves calculations are performed) and to 
reported reserves (which refers to the highest level or the sum of 
individual entity estimates for which reserves estimates are presented).
 Reported reserves should target the following levels of certainty under
 a specific set of economic conditions:
  
- at least a 90 percent probability that the quantities actually recovered will equal or exceed the estimated proved reserves;
 
- at least a 50 percent probability that the quantities actually 
recovered will equal or exceed the sum of the estimated proved plus 
probable reserves; and
 
- at least a 10 percent probability that the quantities actually 
recovered will equal or exceed the sum of the estimated proved plus 
probable plus possible reserves.
 
Additional clarification for the classification of reserves and the
 certainty levels associated with reserves estimates is provided in the 
COGE Handbook.
  Disclosure of Resources
  In this news release, the Company also refers to estimates of 
"contingent resources". These estimates represent the best estimate of 
the contingent resources attributed to the Company's interest, are not 
classified or recognized as reserves, and are in addition to the 
Company's disclosed reserve volumes.
  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. Contingencies may include 
factors such as economic, legal, environmental, political, and 
regulatory matters, or a lack of markets. It is also appropriate to 
classify as contingent resources the estimated discovered recoverable 
quantities associated with a project in the early evaluation stage. 
There is no certainty that it will be commercially viable to produce any
 portion of the contingent resources and the estimated future net 
revenues do not necessarily represent the fair market value of such 
contingent resources.
  The Company's resources classified as contingent resources, rather 
than as reserves, are so classified pending the need for further 
facility design, preparation of firm development plans and regulatory 
applications (including associated reservoir studies and delineation 
drilling) and corporate approvals to proceed with development.
  When evaluating contingent resources, the following mutually exclusive categories are recommended in the COGE Handbook:
  
- 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 90 percent 
probability 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 that the quantity 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 that the quantities actually recovered will equal or exceed 
the high estimate.
 
FORWARD-LOOKING STATEMENTS
  This news release includes forward-looking statements, including 
but not limited to estimates of reserves and resources and the present 
value of revenues associated with such reserves and resources. 
Statements in this news release relating to reserves and resources 
involve the implied assessment, based on certain estimates and 
assumptions, that the described reserves and resources, as the case may 
be, exist in the quantities predicted or estimated, and can be 
profitably produced in the future. There is no assurance that the 
forecast price and cost assumptions contained in the AJM reports will be
 realized and variances could be material. Other assumptions and 
qualifications relating to project schedules, costs and other matters 
are inherent in these estimates.
  In addition, all statements other than statements of historical 
facts, included in this news release that address activities, events, or
 developments that the Company believes or anticipates will or may occur
 in the future are forward-looking statements, including but not limited
 to the Company's intent to pursue the acquisition of additional 
interest in the Kotaneelee property, the Company's planned exploration 
activities and the existence of potential opportunities in the Pacific 
Rim, North America and the Yukon. Such forward-looking statements 
involve known and unknown risks, uncertainties and other factors, which 
may cause the actual results, performance or achievements expressed or 
implied by such forward-looking statements. Such factors include general
 economic and business conditions, the ability to acquire and develop 
specific projects and reach commercially acceptable terms with 
counterparties, the ability to secure government and other third party 
approval, potential third party claims, the ability to fund operations, 
and other factors over which the Company has little or no control. The 
Company does not intend to update publicly any forward-looking 
statements, except as may be required by law. There can be no assurance 
that EFLO will be successful in completing the acquisition of additional
 interest(s) in the Kotaneelee properties or executing its planned 
exploration and development activities.
  The contents of this news release should be considered in 
conjunction with the warnings and cautionary statement contained in the 
Company's public filings, which are accessible on SEDAR at
