Castillian Resources and Ridgemont Iron Ore Sign Definitive Agreement for Proposed Merger

Castillian Resources Corp. ("Castillian") (TSX VENTURE:CT)(OTCQX:CTIIF) and
Ridgemont Iron Ore Corp. ("Ridgemont") (TSX VENTURE:RDG)(OTCQX:RIOOF) have
signed a definitive arrangement agreement (the "Agreement") pursuant to which
Castillian will acquire all of the outstanding shares of Ridgemont by way of a
plan of arrangement under the Business Corporations Act (British Columbia) (the
"Transaction").  


The Agreement contains the principal terms and conditions set out in the binding
letter of intent (the "Letter of Intent") between Castillian and Ridgemont (see
news release dated April 11, 2013) and other customary terms and conditions,
except Mr. Brian Penney, President and CEO of Ridgemont, has agreed to waive any
severance payments that could be triggered by the Transaction in consideration
for Castillian agreeing to increase the consideration under the Transaction to
shareholders of Ridgemont from 0.574 to 0.593 of a Castillian common share for
each common share of Ridgemont held. The board of directors of each company has
unanimously approved the Transaction. Upon completion of the Transaction,
existing Castillian and Ridgemont shareholders will own approximately 57.8% and
42.2% of the combined company, respectively, on a basic shares outstanding basis
(assuming the issuance by Castillian of (a) 8,000,000 common shares to Ryan Gold
Corp. to repurchase Ryan Gold's 10% interest in the Hope Brook gold project (see
news release dated February 6, 2013) and (b) the Severance Shares (as defined
below)). 


Based on the 20-day volume weighted average price ("VWAP") of Castillian's
common shares on the TSX Venture Exchange (the "TSXV") of $0.0590 and the 20-day
VWAP of Ridgemont's common shares on the TSXV of $0.0209, each as of April 10,
2013 (the last trading day prior to the announcement of the Letter of Intent),
the Transaction represents a premium of approximately 67% to Ridgemont (based on
the increased exchange ratio of 0.593). On April 10, 2013, the closing prices of
the Castillian common shares and the Ridgemont common shares were $0.05 and
$0.025, respectively.


Highlights of the Transaction: 



--  The merger will result in an advanced stage gold exploration company
    with a stronger balance sheet focused on Castillian's Hope Brook project
    in Newfoundland; 
    
--  Flow through commitments from Ridgemont's balance sheet will be used to
    fund 5,100 meters of additional diamond drilling, designed to expand the
    existing mineral resource and conduct technical and engineering work
    required for a preliminary economic assessment (PEA) at the Hope Brook
    project; 
    
--  Based on the results of this work, the merged entity anticipates being
    in a position to deliver a Hope Brook PEA by early 2014; 
    
--  Hope Brook has significant indicated and inferred mineral resources in a
    politically favourable jurisdiction with strong upside potential and
    access to existing infrastructure; and  
    
--  The proposed share exchange ratio provides Ridgemont shareholders with a
    42.2% ownership stake in an asset with strong potential. 



Management and Directors:

Following the completion of the Transaction, it is anticipated that Mr. Adrian
Bray, P.Geo., will join Castillian's board of directors and that the current
executive management team of Castillian will be unchanged. 


Mr. Brian Penney is a director of both of Castillian and Ridgemont and the
President and Chief Executive Officer of Ridgemont and, therefore, Castillian
and Ridgemont are non-arm's length parties with respect to each other under the
policies of the TSX Venture Exchange. 


Transaction Details

Pursuant to the terms of the Agreement, the Transaction will be conducted by way
of a court-approved plan of arrangement under the Business Corporations Act
(British Columbia), resulting in Ridgemont becoming a wholly-owned subsidiary of
Castillian. Each Ridgemont common share issued and outstanding immediately prior
to closing of the Transaction will be exchanged for 0.593 of a Castillian common
share. 


All options and warrants of Ridgemont outstanding immediately prior to closing
of the Transaction will, following closing and subject to regulatory approval,
be exercisable for that number of shares of Castillian using the same exchange
ratio applicable to the common shares of Ridgemont under the Transaction, with
corresponding adjustment to the exercise prices on the basis of such exchange
ratio.


On April 24, 2013 Ridgemont and Castillian entered into a loan agreement whereby
Ridgemont advanced to Castillian $250,000 (the "Loan"). The Loan will accrue
interest at the rate of 10% per annum and mature on the earlier of the
completion of the Transaction and the date that is twelve months following the
termination of either the Agreement (the "Maturity Date"). In the event of the
termination of the Definitive Agreement, Ridgemont will have the option to
convert the principal amount of the Loan and all interest accrued thereon at any
time prior to the Maturity Date into common shares of Castillian at a deemed
price of, in the case of the principal amount of the Loan, $0.10 per share, and
in the case of interest accrued thereon, subject to TSXV approval, the current
market price of the Castillian shares less the maximum discount permitted under
the policies of the TSXV. Castillian has the option to prepay the Loan and all
interest accrued thereon in full or in part from time to time at any time prior
to the Maturity Date. 


Certain officers of Ridgemont are contractually entitled to severance payments
that could be triggered by the Transaction. Except for Messrs Mark Morabito and
Brian Penney, these officers have agreed to accept, in aggregate, $25,000 in
lieu of such severance payments, payable immediately prior to completion of the
Transaction in common shares of Ridgemont at a deemed price per share of $0.05
(the "Severance Shares"), subject to the approval of the TSXV. Messrs Morabito
and Penney have agreed to waive any entitlement to any severance payments.


The Transaction is subject to customary conditions, including:



--  approval by a minimum of 66 2/3% of the votes cast by Ridgemont
    shareholders at a duly called special shareholders' meeting; 
    
--  approval/acceptance of the TSXV of the Transaction and the issuance of
    the Severance Shares; 
    
--  all of the directors and officers of Ridgemont agreeing to support the
    Transaction by entering into agreements to vote in favour of the
    Transaction; 
    
--  Ridgemont shareholders holding collectively not more than five per cent
    of the outstanding common shares of Ridgemont having exercised their
    dissent rights; and 
    
--  Ridgemont having working capital upon the closing of the Transaction of
    not less than $2,900,000, less the sum of (i) expenses incurred by
    Ridgemont in connection with the Transaction up to a maximum of $100,000
    and (ii) the principal amount of the Loan. 



The Agreement includes a commitment by each of Castillian and Ridgemont not to
solicit alternative transactions to the proposed Transaction. The Agreement
provides that if a party terminates the Transaction in certain circumstances
such party is obligated to pay to the other party $250,000 on account of costs
and expenses in connection with the Transaction. Each party has also been
provided with certain other rights, representations and warranties and covenants
customary for a transaction of this nature, and each party has the right to
match any competing offers made to the other party.


Ridgemont shareholders will be granted dissent rights which, if exercised in
accordance with applicable requirements, will provide such shareholders the
right to be paid the fair value for their Ridgemont common shares by Ridgemont.


Upon completion of the Transaction, Castillian will have 130.6 million common
shares outstanding (153.6 million common shares on a fully-diluted basis), and
the ownership of the combined company is expected to be approximately 57.8% by
existing Castillian shareholders and 42.2% by former Ridgemont shareholders on a
basic shares outstanding basis (assuming the issuance by Castillian of (a)
8,000,000 common shares to Ryan Gold Corp. to repurchase Ryan Gold's 10%
interest in the Hope Brook gold project (see news release dated February 6,
2013) and (b) the Severance Shares).


Timing

The terms of the Agreement will be described in detail in the management
information circular of Ridgemont to be filed with the regulatory authorities
and mailed to Ridgemont shareholders in accordance with applicable securities
laws in respect of the annual general and special meeting of Ridgemont
shareholders, currently scheduled to be held on June 24, 2013. Subject to
shareholder, court and regulatory approvals, the Transaction is expected to
close in July 2013.


Recommendation of Boards of Directors

The board of directors of each of Ridgemont and Castillian unanimously support
the proposed Transaction. The board of directors of Ridgemont established a
special committee to review the Transaction and retained Evans & Evans, Inc. to
prepare a fairness opinion. The special committee of Ridgemont has received the
fairness opinion from Evans & Evans, Inc. which states that the consideration to
be received by the Ridgemont shareholders is fair, from a financial point of
view, to the Ridgemont shareholders. The board of directors of Ridgemont
recommends that Ridgemont shareholders vote in favour of the Transaction at the
shareholder meeting to be called to approve the Transaction. The reasons for the
board of directors' recommendation will be detailed in the aforementioned
management information circular.

    historic resources in the former Hope Brook mine in addition to new
    areas of resource as defined by Castillian, including the Pit Zone,
    Hanging Wall Zone and Mine Zone Extension. 
    
--  There is a possible copper credit that is not included in the mineral
    resource due to missing copper assays in historical drill holes.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain information contained in this press release, including any information
relating to the Transaction (including the anticipated benefits of the
Transaction), and statements that address events or developments that Castillian
or Ridgemont expects to occur, are "forward-looking statements". Forward-looking
statements are statements that are not historical facts and are generally, but
not always, identified by the words "expects", "does not expect", "plans",
"anticipates", "does not anticipate", "believes", "intends", "estimates",
"projects", "potential", "scheduled", "forecast", "budget" and similar
expressions, or that events or conditions "will", "would", "may", "could",
"should" or "might" occur. Forward-looking statements include, but are not
limited to, statements relating to completion and timing of the acquisition of
Ridgemont, the delivery of the Hope Brook PEA, the upside potential of Hope
Brook and the Hope Brook mineral resource estimate and its potential to be
increased. All such forward-looking statements are subject to important risk
factors and uncertainties, many of which are beyond Castillian's or Ridgemont's
ability to control or predict. Forward-looking statements are necessarily based
on estimates and assumptions that are inherently subject to known and unknown
risks, uncertainties and other factors that may cause Castillian's or
Ridgemont's actual results, level of activity, performance or achievements to be
materially different from those expressed or implied by such forward-looking
statements. Assumptions upon which such forward-looking statements are based on
include the estimation of mineral resources, the availability of necessary
financing and materials to continue to explore and develop Hope Brook, that
Castillian and Ridgemont will be able to satisfy the conditions contained in the
Letter of Intent, that the required approvals will be obtained from the
shareholders of Ridgemont, that all third party, court, regulatory and
governmental approvals to the Transactions will be obtained, including from the
Exchange and all other conditions to completion of the Transaction will be
satisfied or waived. Many of these assumptions are based on factors and events
that are not within the control of Castillian and Ridgemont and there is no
assurance they will prove to be correct. Such factors include, without
limitation: capital requirements; fluctuations in the international currency
markets and in rates of exchange of metal prices; changes in national and local
government legislation in Canada or any other country in which Castillian and
Ridgemont currently or may in the future carry on business; taxation; controls,
regulations and political or economic developments in the countries in which
Castillian and Ridgemont do or may carry on business; competition; loss of key
employees; and additional funding requirements; 


Any forward-looking statement speaks only as of the date on which it is made and
Castillian and Ridgemont expressly disclaim any intention or obligation to
update or revise any forward-looking statements, whether as a result of new
information, events or otherwise, except in accordance with applicable
securities laws. Although each of Castillian and Ridgemont believe that the
assumptions inherent in the forward-looking statements are reasonable,
forward-looking statements are not guarantees of future performance and
accordingly undue reliance should not be put on such statements due to the
inherent uncertainty therein.
