TORONTO, ONTARIO--(Marketwire - Feb. 27, 2012) - Argonaut Gold Inc. (News - Market indicators) ("Argonaut" or the "Company") is pleased to announce its plans for 2012 project initiatives for both of the Company's operating mines in Mexico. The El Castillo mine is located 100 km north of the capital city of Durango in Durango, Mexico, and the La Colorada mine is located 50 km southeast of the capital city of Hermosillo in Sonora, Mexico.

El Castillo 2012 Initiatives:

• Mining Fleet
  • In Q1, the haulage fleet will increase to a total of 18, one hundred ton capacity trucks.
• Expanding heap leach capacity
  • In Q2, west leach pad #7A will be commissioned, providing an additional 2.6 million tonnes capacity.
• Reducing truck haulage requirements
  • In Q3, a new crushing, conveying and stacking system will be in place reducing truck haulage requirements.
• Future Pad expansions
  • In Q4, construction to begin on pad #8 on the west side land which was acquired at the end of 2011.

Pete Dougherty, Argonaut President and CEO, stated: "These initiatives will be implemented in a stepped phase throughout the year, and are designed to create a more efficient mining environment at El Castillo. At the end of last year as we extended operations to the east pads and plant, El Castillo experienced higher cash operating costs. We feel these initiatives will mitigate these costs. We believe El Castillo will be in a position to take the next steps in advancing production by year end with the addition of the new west pad #8."

La Colorada 2012 Initiatives:

• Production in Q1
  • The Company began stacking and leaching material early in the first quarter.
• Completion of desorption plant and refinery
  • Expected to be completed in Q2, this new plant will provide refining capacity for all Mexican operations allowing for faster metal recovery and sales.
• Expanding Mine Footprint
  • In Q2, the phase two permit for expansion is expected to be received and mining is to begin at the La Colorada pit.

Mr. Dougherty commented: "The Company is happy to announce that gold production has begun at the La Colorada mine. We are currently reprocessing material from the existing leach pads. Construction is well underway on the new desorption and recovery plant, as well as the refinery. When completed in the second quarter, it will have the capacity to handle material from all of the Company's Mexican operations. The enhancement of the desorption and refining circuit will allow the Company to process all loaded carbon at a single site, therein reducing costs, and expediting our sales process. It is satisfying to see the La Colorada mine begin ahead of schedule and continue to expand." 

Total Capital Expansion Program for 2012

Mr. Dougherty commented: "The Company is pleased to add a second producing mine to the Company's portfolio. The initiatives underway at both mines will allow for greater efficiencies and enhancements to production. Gold production at El Castillo is expected to be between 17,000 and 18,000 ounces for Q1 and is budgeted to increase each quarter. Q4 production is expected to reach 21,000 - 22,000 ounces, finishing the year for a total of 75,000 and 80,000 ounces at an average cash cost for the year of $625 to $650 per ounce. Gold production at La Colorada is expected to be between 2,000 and 2,500 ounces of gold for Q1 with gradual increases anticipated each quarter;. Q4 production is expected to be between 4,500 - 5,500 ounces at an average cash cost for the year of $625 to $650 per ounce. Full year La Colorada production is expected to be 13,500 to 17,000 ounces."
