Endeavour Silver and AuRico Gold Sign Definitive Agreement

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 15, 2012) - Endeavour Silver Corp. (TSX:EDR)(NYSE:EXK)(FRANKFURT:EJD) ("Endeavour") and AuRico Gold Inc. (TSX:AUQ)(NYSE:AUQ) ("AuRico Gold") are pleased to announce that they have entered into a definitive agreement whereby Endeavour will acquire 100% interests in AuRico Gold's operating El Cubo silver-gold mine in Guanajuato State, Mexico and the Guadalupe y Calvo silver-gold exploration project in Chihuahua State, Mexico, for total consideration of up to US$250 million.

On Closing, Endeavour will pay AuRico Gold US$200 million, comprised of, at Endeavour's election, up to US$100 million of the purchase price in Endeavour common shares and the balance in cash. Post-Closing, AuRico Gold will be entitled to receive up to an additional US$50 million in cash payments from Endeavour upon the occurrence of certain events during the three years following Closing.

El Cubo is a producing silver-gold mine located in the southeast part of the historic Guanajuato mining district in central Mexico, only 10 kilometers (km) from Endeavour's operating Guanajuato silver-gold mine in the northwest part of the Guanajuato district (see attached map).

Guadalupe y Calvo is an advanced silver-gold exploration project located in the historic Guadalupe y Calvo mining district in Chihuahua State, Mexico, approximately 300 km southwest of the city of Chihuahua. AuRico Gold recently announced an updated resource estimate and preliminary economic assessment envisioning a combined open pit and underground silver-gold mining operation at Guadalupe y Calvo.

The acquisition of the El Cubo mine is an excellent fit within Endeavour's growth strategy of buying mines in historic mining districts where management can create shareholder value by bringing its expertise and capital to bear on expanding reserves and resources, improving mine and mill operations and growing silver and gold production. El Cubo complements Endeavour's Guanajuato mine and should provide operational synergies going forward, as well as boosting Endeavour's silver production to immediately move it into the mid-tier of primary silver producers, with little or no equity dilution to shareholders.

The acquisition of the Guadalupe y Calvo project also fits well with Endeavour's growth strategy as it is located in an historic mining district and has good exploration upside to increase silver-gold resources and the potential to become Endeavour's fourth mine. Endeavour plans to further explore Guadalupe y Calvo with additional drilling before re-assessing its mining potential.

For AuRico Gold, this announcement follows the recent signing of a definitive agreement with respect to the divestiture of AuRico Gold's Australian mines and is consistent with AuRico Gold's strategy of focusing on its large, low cost, core assets. AuRico Gold is now directing all of its attention to delivering value for shareholders from its three operating mines, including Young-Davidson where first production is imminent, and its development pipeline in Mexico and Canada.

Bradford Cooke, Chairman and CEO of Endeavour, commented, "El Cubo's proximity and similarity to, and potential synergies with, our Guanajuato mine, make El Cubo a logical and strategic acquisition for Endeavour that will have an immediate and sizable impact on our production, reserves and resources with minimal or no dilution to our shareholders. We hope to replicate at El Cubo the same types of exploration and operational successes that we have engineered at our Guanacevi and Guanajuato mines."

Rene Marion, President and CEO of AuRico Gold, commented, "AuRico Gold is pleased to have reached an agreement with Endeavour Silver on the El Cubo and Guadalupe y Calvo properties. AuRico Gold views Endeavour as a logical owner for these properties and are solid operators positioned to deliver on the potential we see at both the El Cubo and Guadalupe y Calvo properties. We look forward to participating in the future success of these two assets through our potential ownership interest in Endeavour and through the future receipt of the contingent payments."
