Richard Rhoades, Chief Operating Officer of Argonaut Gold said "Year-end production at El Castillo of 87,712 gold ounces came in above increased guidance of 85,000 ounces for the year. The team at El Castillo team delivered yet another quarter of continued improvement, providing a 10% increase over the initial 2012 guidance. In addition to exceeding guidance expectations, the Company has seen dramatic improvement in crushing at the operation. The operation is now crushing at a rate of approximately 5 million tonnes per year."

Production has approached a near steady state at El Castillo. Higher grade material during the fourth quarter of 2012 provided for production of over 25,000 ounces against to guidance of 21-22,000 ounces for the quarter. In 2013, the operation anticipates lower grades, offset by higher volumes of material, for an estimated 5-10% increase over total 2012 production.

FOURTH QUARTER 2012 LA COLORADA OPERATING RESULTS

Overburden removal continues at La Colorada in preparation for full scale mining. During the fourth quarter, the crusher was relocated with a minimal impact to the production plan. Fourth quarter production provided 6,195 ounces of gold, for a total 2012 production of 20,369 ounces. Final production exceeded expectations due to higher than anticipated recoveries from the reprocessing of material and positive grade reconciliation.
