Financial Results – First Quarter 2011

Cash cost per gold ounce for units sold (see Non-IFRS measures section note below) was $590 compared to $1,107 in the same period of 2010 principally because the ounces sold in first quarter of 2010 had been fair valued on the acquisition of Castle Gold.

CEO Commentary

Mr. Pete Dougherty, Argonaut's President and CEO states: "The year of 2011 began with a substantial increase in reserves and resources at El Castillo. Progress on the east side expansion has continued with barren pipe and wet testing of the new plant, laying overliner on newly built additional pad space and construction of a new crushing circuit." He added "This quarter marks the second quarter of an annualized production rate of 72,000 ounces, with cash costs at $590 per gold ounce sold. This is in line with Company guidance for 2011."

Non-IFRS Measures

The Company included the non-IFRS measure "Cash cost per gold ounce for units sold" in this press release to supplement its financial statements which are presented in accordance with International Financial Reporting Standards ("IFRS"). Cash cost per gold ounce for units sold is equal to cost of sales less silver sales divided by gold ounces sold. The Company believes that this measure provides investors with an improved ability to evaluate the performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS. Therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
