• Over 74,000 tonnes per day mined and 2.8 million ore tonnes placed on the heap leach pads during the quarter.
• Advancement of the construction of the valley between pad 8 and 1-7 (90% complete) and 3B East (1/3 complete) pads.

  • Phase I of pad 6 finished.
  • Pad 9A ground cleared.

Pete Dougherty, Argonaut Gold's President and CEO, said, "Argonaut continued to have strong production in the first quarter of 2015, in which we produced nearly 31% of the full year production guidance. We continue to see the benefits of operating at a higher cyanide concentration in the circuit, by way of improved recoveries.

The production results in the first quarter exceeded expectations; however, the Company would like to reiterate that production is anticipated to be higher during the first part of 2015 and will taper off during the latter part of the year. Production guidance of 135,000 to 145,000 ounces during 2015 is maintained. We anticipate that costs will trend higher as we continue to use additional cyanide.

The operating teams achieved tremendous production results at both operations, setting us up well in terms of achieving our full year goals in 2015. These goals are: continuing to focus on our core principles of safe and efficient operations, meeting production goals and targets, controlling costs and advancing and adding value to our portfolio of development projects."

FIRST QUARTER 2015 El CASTILLO OPERATING STATISTICS

FIRST QUARTER 2015 LA COLORADA OPERATING STATISTICS

Richard Rhoades, Chief Operating Officer of Argonaut Gold, said, "At El Castillo, we are pleased that we were able to deliver solid production results. In spite of an unusually rainy first quarter, which resulted in five days of lost production, we were able to maintain a safe and efficient mine. We began adding a higher cyanide concentration on the pads and have achieved higher recovery from the leach pads. We are looking to further optimize the mine during the second quarter to enhance our margins.

At the La Colorada Mine, with the expansion projects completed last year, the first quarter resulted in a second consecutive quarter of record production. The crushing circuit continues to process greater than 12,000 tonnes per day, and we are set up to continue to deliver strong results. The added flexibility of reprocessing leach pad material from the historic leach pads, and mining the main La Colorada/Gran Central pit, should provide the operational flexibility to more effectively manage operations and costs."

2015 Development and Growth

Development project updates

• Drilling of 36 holes for over 9,900 metres completed at Magino. Focusing on the extension of mineralization onto the Richmont ground and infill drilling of the main area of the current resource.
• Ongoing negotiations for land and preparation of Environmental Impact Assessment at San Agustín.

Peter Dougherty said "At Magino, ongoing drilling is promising and a full set of assay results are expected to be released during the second quarter. This information will be used to define a new resource and Preliminary Economic Assessment. At San Agustín, we are continuing to prepare for the submission of permits and are encouraged by our ability to realize additional upside potential through future drilling programs. We continue to invest time and resources in order to move the San Antonio project forward. The Company believes in the social and economic benefits of the San Antonio project, and continues to patiently pursue permits through the 2015 election cycle."
