Oro Mining Board Unanimously Recommends Shareholders Reject Wexford's Unsolicited Offer

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 13, 2012) - Oro Mining Ltd. ("Oro" or the "Company") (TSX VENTURE:OGR) announced today that its Board of Directors unanimously recommends that shareholders reject the unsolicited offer by Wexford Spectrum Trading Limited and Wexford Catalyst Trading Limited, private investment funds managed and controlled by Wexford Capital LP ("Wexford"), to acquire any and all common shares of Oro at a price of $0.11 per common share. The Board determined that the Wexford offer fails to provide adequate value for Oro shares and is an attempt by Wexford to acquire Oro shares without offering adequate consideration to Oro shareholders. Accordingly, the Board recommends that Oro shareholders reject the Wexford offer and do not tender any of their shares to the offer.

Robert Kendrick, Chairman of Oro's Board of Directors, stated, "After careful review, the Board has concluded that the Wexford offer does not adequately reflect the value of Oro's Taunus deposit, other mineral properties, current working capital position and upside and growth potential. The recently announced Preliminary Economic Assessment for the Taunus deposit assigned a pre-tax net present value of US$79 million. Wexford is offering only approximately $21 million for the entire company. Wexford's "lowball" opportunistic offer appears clearly intended to take advantage of investor's fears due to the depressed state of the market for junior resource stocks."

A copy of the Directors' Circular, which sets forth in greater detail the Board's recommendation and the reasons for the recommendation, will be mailed to all Oro shareholders shortly. These reasons include, but are not limited to, the following:

• The Wexford offer significantly undervalues the Company's common shares.
• The Wexford offer is opportunistic and coercive.
• The Wexford offer is highly conditional and not a firm offer.
• The Wexford offer is financially inadequate.
• The Wexford offer does not reflect an adequate premium for control of Oro.
• None of the directors or officers of Oro intend to tender their common shares to the Wexford offer.
• A number of shareholders have advised that they also consider the offer to be inadequate and no shareholder has indicated an intention to tender to the Wexford offer.

Ross Glanville & Associates Ltd. ("Glanville"), the financial advisor to the Special Committee of independent directors appointed by the Board of Directors (the "Special Committee"), has provided a written opinion to the Special Committee and the Board that, as of the date of such opinion, the consideration offered pursuant to the Wexford offer is inadequate, from a financial point of view, to Oro shareholders other than Wexford and its affiliates and joint actors. The full text of Glanville's opinion, which Oro shareholders are urged to read in its entirety, will be included in the Directors' Circular.
