Iona Energy Inc. (TSX VENTURE:INA) ("Iona" or the "Company") is pleased to
provide an operational update regarding production and reserves and that gas
compression has commenced at the Huntington Field.


Huntington and Corporate Production

On June 5th, 2013, first gas was exported from the Huntington Field, of which
Iona owns a 15% working interest and a 2.55% royalty interest. Production from
Huntington on June 7th was approximately 10,500 boepd gross (1,842 boepd net to
Iona including the royalty interest).


Production has been steady since gas compression commenced and is expected to
continue to increase until it reaches the predetermined Floating Production
Storage and Offloading unit capacity of 30,000 bbls/d of oil and 27 MMcf/d by
the end of June 2013. As a result of the aforementioned, Iona has reached a new
production record of approximately 3,464 boepd, which is expected to increase to
over 7,500 boepd as Huntington reaches production capacity.


The working interests in the Huntington field are E.ON Ruhrgas UK E&P (25%
Operator), Premier Oil plc (40%), Norwegian Energy Company ASA (20%), and Iona
(15%). In addition to the working interest, Iona holds a gross overriding
royalty of 2.55% of the total Huntington production, payable from the Huntington
Joint Venture Partners.


Corporate Reserves

The Company is also pleased to announce that independent reserves evaluator
Gaffney, Cline & Associates Ltd. ("GCA") has completed its evaluation of Iona's
interest in the Huntington property. GCA evaluated, effective as of December 31,
2012, the reserves and net present values of future revenue associates
therewith, and using forecast prices and costs. The proved and probable reserves
from Huntington net to Iona based on a 15.75% interest (15% working interest and
0.75% differential lifting entitlement) are 4.58 MMboe (4.14 MMbbls of oil and
2.64 Bcf of gas), not including the additional royalty interest of 1.8%., the
results of which are integrated into Iona's full portfolio as set forth below.


Readers should note that these figures are based on the approved field
development plan for Huntington and do not take full account for the recent
development drilling results on the property. Iona expects to provide a further
update on the reserves associated with Huntington later in 2013 once production
results associated with Huntington's expected maximum production capacity have
been analyzed. Also, the updated reserves and net present values listed below
accurately reflect Iona's current working interests in its Orlando and Kells
properties. The previously disclosed reserve report (released April 30th, 2013)
included Orlando and Kells reserves and net present values at 100% working
interest, while the figures below reflect a 75% working interest.


Specifically, the changes from Iona's reserve report released on April 30, 2013
and the figures below are as follows (gas converted to barrels of oil equivalent
by Iona at 6,000 cubic feet per 1 barrel of oil):




--  Proved pre-tax net present value 10% increased from US$483.38 million to
    US$620.59 million, up 28%. 

--  Proved plus probable pre-tax net present value 10% increased from
    US$1,184.64 million to US$1,255.94 million, up 6%. 

--  Proved post-tax net present value 10% increased from US$293.03 million
    to US$408.15 million, up 39%. 

--  Proved plus probable post-tax net present value 10% increased from
    US$643.91 million to US$755.31 million, up 17%. 

--  Adjusting for Orlando and Kells working interest adjustment proved
    reserves increased from 15.2 MMboe to 18.8 MMboe, up 24%. 

--  Adjusting for Orlando and Kells working interest adjustment proved plus
    probable reserves increased from 29.7 MMboe to 34.3 MMboe, up 15%.

Notes:



1.  Iona's Interest reserves are based upon a 75% working interest in
    Orlando. 
2.  Iona's Interest reserves are based upon a 58.73% working interest in
    West Wick. 
3.  Iona's Interest reserves are based upon a 75% working interest in Kells.
4.  Iona's Interest reserves are based upon a 20% working interest in Trent
    & Tyne. 
5.  Iona's Interest reserves are based upon a 15% working interest plus a
    0.75% royalty in Huntington. 
6.  In addition to the above working interest in Huntington, Iona receives
    an additional 1.8% revenue interest payable less certain cost deductions
    which is included in the above NPV estimates. 
7.  The post-tax net present value of Iona's oil and gas properties here
    reflects the tax burden on the properties on a stand-alone basis. It
    does not consider the business-entity-level tax situation, or tax
    planning. It does not provide an estimate of the value at the level of
    the business entity, which may be significantly different. The financial
    statements and management's discussion & analysis (MD&A) of Iona should
    be consulted for information at the business entity level. 
8.  In addition to the items set forth in the table below, key assumptions
    for post-tax net present value of Iona's oil and gas properties include
    the utilization of existing tax pools, the application of the recently-
    enacted U.K. small field allowance to Iona's interest in the Kells
    field, and use of GCA's forecast prices and costs. No other adjustments
    have been made for cash balances, inventories, indebtedness or other
    balance sheet effects.

Forward-looking statements

Some of the statements in this announcement are forward-looking, including
statements regarding estimates of the quantities of reserves, associated net
present values of future revenue therefrom, and contingent resources in the
Huntington field. Forward-looking statements include statements regarding the
intent, belief and current expectations of Iona Energy Inc. or its officers with
respect to various matters, including production, drilling activity or
otherwise. When used in this announcement, the words "expects", "believes",
"anticipate", "plans", "may", "will", "should", "scheduled", "targeted",
"estimated" and similar expressions, and the negatives thereof, are intended to
identify forward-looking statements. Such statements are not promises or
guarantees, are based on various assumptions by Iona's management, including the
assumption with respect to the timing and effects of commissioning gas
compression systems for Huntington which are beyond Iona's control, and are
subject to risks and uncertainties that could cause actual outcome to differ
materially from those suggested by any such statements, including without
limitation, the risk of unanticipated delays impacting production rates at
Huntington. These forward-looking statements speak only as of the date of this
announcement. Iona Energy Inc. expressly disclaims any obligation or undertaking
to release publicly any updates or revisions to any forward-looking statement
contained herein to reflect any change in its expectations with regard thereto
or any change in events, conditions or circumstances on which any
forward-looking statement is based except as required by applicable securities
laws.


Notes Regarding Oil and Gas Disclosure

As used in this press release, "boe" means barrel of oil equivalent on the basis
of 6 mcf of natural gas to 1 bbl of oil. Boes may be misleading, particularly if
used in isolation. A boe conversion ratio of 6 mcf: 1 bbl is based on an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead.


It should not be assumed that the present worth of estimated future net revenue
represents the fair market value of the reserves disclosed in this press
release. The reserve and related revenue estimates set forth in this press
release are estimates only and the actual reserves and realized revenue may be
greater or less than those calculated. The estimates of reserves and future net
revenue for individual properties may not reflect the same confidence level as
estimates of reserves and future net revenue for all properties due to the
effects of aggregation. As used in this press release, "possible reserves" are
those additional reserves that are less certain to be recovered than probable
reserves. There is a 10% probability that the quantities actually recovered will
equal or exceed the sum of proved plus probable plus possible reserves.


Additionally, this press release uses certain abbreviations as follows:
