JNR Resources Inc. Announces Plan of Arrangement with Denison Mines Corp.

SASKATOON, Nov. 28, 2012 - Mr. Richard Kusmirski, President of JNR Resources Inc. (TSXV: JNN) ("JNR" or the "Company") announces Denison Mines Corp. (DML: TSX; DNN: NYSE MKT) ("Denison") and JNR have entered into an Amending Agreement to amend their previously announced Acquisition Agreement, so that Denison's acquisition of JNR will now proceed by way of a Plan of Arrangement (the "Arrangement") instead of a take-over bid (the "Bid").

The acquisition of JNR shares under the Arrangement will occur on substantially the same terms as the Bid, in that JNR shareholders will receive 0.073 of one Denison common share (the "Exchange Ratio") in exchange for each JNR common share held on the record date of December 12, 2012. The Arrangement will also provide for the issuance by Denison of replacement warrants and options to holders of outstanding JNR warrants and options on similar terms as adjusted by the Exchange Ratio. The completion of the Arrangement will be subject to usual terms and conditions, including the following:

a) Approval of the Arrangement by special resolution of JNR's shareholders, optionholders and warrantholders;

b) Court approval of the Arrangement;

c) Receipt of any required third party approvals and consents; and

d) Receipt of all required regulatory approvals, including acceptance by the TSX Venture Exchange.

Key provisions of the Acquisition Agreement, such as the non-solicitation covenant on the part of JNR, the right in favour of Denison to match any superior proposal and the termination fee of $325,000 payable to Denison in certain circumstances including if JNR accepts a superior proposal, have not been amended.

The Arrangement allows the transaction to be completed within the same approximate time frame as the Bid, with closing planned for February 1, 2013, but on a more cost effective basis. Documents relating to the Arrangement, including the information circular required in connection with JNR's special shareholder meeting scheduled for January 28, 2013, are to be mailed to JNR shareholders in early January 2013.

This press release does not constitute an offer to buy or an invitation to sell, or the solicitation of an offer to buy or invitation to sell, any securities of Denison or JNR. Subject to the terms and conditions set forth in the Acquisition Agreement, as amended, JNR intends to file a notice of meeting, management information circular and related materials with Canadian securities regulatory authorities relating to the proposed transaction, and Denison intends to file a registration statement and prospectus with the United States Securities and Exchange Commission (the "SEC"), including the JNR management information circular and related materials, relating to the proposed transaction. Investors and security holders are urged to read these documents, as well as any amendments and supplements to these documents, when they become available because they will contain important information. At that time, investors and security holders may obtain a free copy of the JNR management information circular and related documents at the Canadian securities regulators' website at www.sedar.com and a free copy of the registration statement and prospectus and related documents at the SEC's website at www.sec.gov. At that time, free copies of these documents can also be obtained by directing a request to Denison at 595 Bay Street, Suite 402, Toronto, Ontario, Canada, M5G 2C2.

YOU SHOULD READ THE MANAGEMENT INFORMATION CIRCULAR, PROSPECTUS AND RELATED MATERIALS CAREFULLY BEFORE MAKING A DECISION CONCERNING THE PROPOSED TRANSACTION.
