TORONTO, ONTARIO--(Marketwired - April 15, 2013) - Argonaut Gold Inc. ("Argonaut Gold" or the "Company") (News - Market indicators), announced today that the Company had gold production of 28,907 ounces during the 1st quarter ended March 31, 2013. This included 23,125 ounces at its 100% owned El Castillo Mine ("El Castillo") located in Durango, Mexico and 5,782 ounces of gold at its 100% owned La Colorada Mine ("La Colorada") located in Hermosillo, Mexico. Argonaut Gold is continuing its ramp up of production at both operations and we expect production increases as the year progresses. The Company is also pleased to announce an updated resource for the Veta Madre deposit at La Colorada with good expansion potential within the surrounding geologic environment.

FIRST QUARTER 2013 HIGHLIGHTS:

El Castillo

• Production of 23,125 gold ounces, representing a 30% improvement over Q1 2012.
• 36,023 gold ounces loaded on the pad, a 2% improvement over Q1 2012.
• West Side Pad 8 construction continues to make good progress and we have now begun loading and leaching.
• Argonaut now operating all mining at El Castillo, having assumed contractor activities in March.

La Colorada

• Production of 5,782 gold ounces, an 87% improvement over Q1 2012.
• Production of 44,879 silver ounces, a 161% improvement over Q1 2012.
• 3,763 gold ounces and 70,694 silver ounces loaded on the pad.

Richard Rhoades, Chief Operating Officer of Argonaut Gold said, "2013 will be an important year at El Castillo. The Company is moving forward its expansion programs this year. Nearly 30 million tonnes of pad capacity will be built on the west side pad #8. Our goal is to achieve our production targets while concurrently building for the future. In addition, capital expenditures for a west side crusher/overland conveyor, aimed at reducing costs, will be completed and fully operational in the third quarter." Mr. Rhoades added, "The grade this quarter was due to higher than anticipated grades mined on the north side of the pit."

Commenting on La Colorada production, Mr. Rhoades said, "Mining during the first half of the year will be of lower grade with a higher strip ratio. During the second half of the year, the tonnes processed are expected to increase, along with the overall grade."

Veta Madre Deposit Adds 110,000 Inferred Gold Ounces at La Colorada, Surrounding mineralized envelope provides potential growth in ounces

The Company is pleased to report an updated NI 43-101 compliant mineral resource from SRK Consulting of Denver, CO ("SRK") showing an inferred resource of 110,145 gold ounces and 701,908 silver ounces at the Veta Madre deposit, which forms part of the La Colorada mineral system. The resource contained within an optimized Whittle-Pit consists of 6.7 million tonnes of material at an average grade of 0.51 g /t of gold and 3.25 g/t silver. Economic parameters utilized in this Whittle Pit optimization are based on actual costs realized at the La Colorada operation, a cut-off grade of 0.10 grams/tonne and metallurgical test work performed by Kappes, Cassiday & Associates ("KCA") of Reno, NV. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as mineral reserves. There is no assurance that any part of the inferred resources will ultimately be converted to mineral reserves.

Mineralization at Veta Madre is oxidized material which begins at surface and runs to the current drill depths of 170 meters. Expected recoveries are estimated at 85% for gold and 15% for silver, as determined by column heap leach testing completed by KCA. The resource outlined above is constrained to our surface right concessions and only recovers parts of a much larger mineralized envelope. The Company anticipates additional resource could be added to the production profile if additional surface rights can be acquired.

La Colorada Exploration Potential

In regards to exploration potential at the property, Tom Burkhart, Vice President of Exploration said, "The current resources at La Colorada are part of a large gold-silver district that historically has produced between three and five million ounces of gold. The Company is currently reviewing satellite gold targets in proximity to the mine. These mineralized zones show evidence of limited past underground production where potential remains for open-pit extraction of mineralized wall-rock. These surrounding gold occurrences offer significant potential, and may add resources to the La Colorada operation. Also offering long-term upside at La Colorada is known high-grade mineralization that underlies all of the current open pit mining operation. The Company believes there is potential for underground mining at La Colorada and will be conducting further studies to evaluate this in 2013."

First Quarter Highlights

Pete Dougherty, President and CEO of Argonaut Gold said, "The Veta Madre resource is an exciting addition which could add near term production at La Colorada. The Company aims to permit this area for production within the next year. The production is anticipated to add approximately 10-20,000 ounces annually, with minimal capital requirements. This would be built as a heap leach operation with solution pumped to the La Colorada plant."

Mr. Dougherty added, "During the first half of 2013, production expectations are for 46,000 ounces of gold at El Castillo and 9,000 ounces of gold at La Colorada. We anticipate that production will increase in the second half of 2013, with 49,000 gold ounces at El Castillo and 27,000 gold ounces at La Colorada. We are excited by the accomplishments at both mines and look forward to how capex invested through 2013 will lead to production growth and cash cost decreases at both operations."
