BELO HORIZONTE, Brazil, May 8, 2012, 2012 (Canada NewsWire via COMTEX) --JAG - TSX/NYSE

Jaguar Mining Inc. ("Jaguar" or the "Company") (JAG: TSX/NYSE) today announced that the Special Committee of the Company's Board of Directors has concluded its strategic review process respecting the possible change of control of Jaguar. Despite the Committee's extensive efforts, this process has not resulted in an agreed change of control transaction.

The strategic review process was announced by the Company on November 16, 2011 in response to a media report of a change of control proposal from the Shandong Gold Group. Immediately following the issuance of that release, the Company established a Special Committee comprised exclusively of independent directors to take primary responsibility for the process, and retained J.P. Morgan Securities LLC and Davies Ward Phillips & Vineberg LLP as financial and legal advisors, respectively, to assist the Special Committee and the Board in completing the process.

When the proposal was received from the Shandong Gold Group in November 2011, the Board determined that it was not in the best interests of the Company and its shareholders to accept that proposal. The Shandong Gold proposal was structured so as to effectively provide Shandong Gold with an option to purchase the Company as it conducted due diligence and sought government approvals, including those required in China, while preventing the Company from exploring other alternatives. In addition to Shandong Gold, two other parties, including the North American based mining company referred to below, had expressed interest in acquiring the Company in the fall of 2011. These interested parties emerged as a result of the Company's practice of maintaining contact with various mining companies who might be interested in acquiring the Company if the opportunity arose.

As part of the process, the Company and its financial advisor contacted or received contact from 22 parties regarding a potential change of control or other strategic transaction. Five of those parties executed confidentiality agreements and were provided access to an extensive data room. Three of those parties conducted site visits in Brazil. Throughout this process, the Special Committee held 17 formal meetings and had numerous, frequently daily, informal discussions and communications.

Ultimately, one party, a North American based mining company, expressed a serious intention to pursue an acquisition of the outstanding shares of Jaguar, though others expressed interest in acquiring assets of the Company. In early February, that party provided a preliminary proposal respecting the acquisition of Jaguar at a price of between U.S. $8.20 and U.S. $9.45 per share, conditional upon, among other things, the completion of a diligence investigation of Jaguar.

Throughout February and March, that party engaged in an extensive due diligence process, including site visits to Jaguar's projects from late February to early March, numerous face to face or telephonic discussions with Company personnel, members of the Special Committee and the Company's financial advisor, and extensive documentary diligence. That diligence process continued until early April.

In late March, that party was provided with a form of the definitive agreement that the Company was prepared to enter into. After discussions between that party and the Special Committee and its financial advisor, including a meeting between that party and two members of the Special Committee in Toronto on April 11, 2012, that party notified the Company in the afternoon of April 13, 2012 that it had determined not to proceed with an acquisition of the Company at this time.

Since the formation of the Special Committee, the Committee, directly and through the Company's financial advisor and other intermediaries, has made persistent and repeated efforts to engage with the Shandong Gold Group to determine if there was a basis for pursuing change of control discussions. On a number of occasions the Special Committee offered to meet with representatives of Shandong Gold in Hong Kong, Beijing or at any other locale of their choosing. Shandong Gold was not willing to be a participant in the formal strategic review process and did not respond to those efforts of the Special Committee.

On April 3, 2012, representatives of Shandong Gold, through an intermediary, received the form of definitive agreement that the Company was prepared to enter into. However, the Company did not receive any response to that form of agreement.

In response to media reports on April 12, 2012 that quoted a representative of Shandong Gold as remaining interested in Jaguar, in the morning of April 13, 2012, a letter from the Chairman of the Company to the Chairman of Shandong Gold was provided to counsel to Shandong Gold for presentation to Shandong Gold. This letter expressed the willingness of members of the Special Committee to travel to a location convenient to Shandong Gold within the next 10 days to engage in direct senior level discussions to explore a mutually agreeable transaction.

On April 18, 2012, the Company provided Shandong Gold, through the Company's intermediary, a draft letter of intent and a form of exclusivity agreement under which the Company would have entered into exclusive discussions with Shandong Gold. On April 20, 2012, the Company's intermediary informed the Special Committee that Shandong Gold was considering those documents with its financial and legal advisors. A meeting between the Company's intermediary and the Chairman of Shandong Gold was scheduled for May 1, 2012. This meeting was subsequently rescheduled for May 7, 2012 as a result of the Labour Day holiday in China on May 1.

In the morning of May 8, 2012, Jaguar's intermediary informed the Special Committee that it has been advised that Shandong Gold has determined not to proceed with further acquisition discussions.

At a meeting in the morning of May 8, 2012, the Board of Directors, based on a recommendation of the Special Committee, terminated the strategic review process respecting the possible change of control of Jaguar. However, the Board will consider any future proposals if and when they may be received.

In addition, the Special Committee is continuing discussions with a party interested in the possible acquisition of one of Jaguar's producing mining operations. No assurance can be given that the Company will receive any proposals or consummate a sale transaction.

Gil Clausen, Chairman of the Special Committee, said, "It has been a challenging time to attract interest in the Company due to the operational issues we have faced, coupled with the material decline in the gold equity markets over the last few months. Although the formal process has concluded and did not result in a change of control of the Company, the Board will actively consider any future proposals that may be received."

The Special Committee believes that the following factors have contributed to the strategic review process not resulting in a change of control transaction:

    --  The S&P TSX Global Gold index had declined by 31% since
        November 15, 2011.  A material decline in the equity prices of
        several of the prospective bidders for the Company, including
        the North American based mining company referred to above, has
        had a negative impact on their willingness or ability to
        proceed.
    --  Jaguar is continuing to resolve operational issues at its
        southern operations in Brazil.  The Company is confident of its
        ability to resolve the issues and, as announced today, the
        Company is implementing a comprehensive restructuring and
        turnaround plan to improve costs and efficiency at its southern
        operations.  However, together with current gold equity market
        conditions, concerns about these operational issues have made
        it more challenging for interested parties to pursue a change
        of control transaction.
