Toronto, Ontario – (March 27, 2018) Argonaut Gold Inc. (TSX: AR) (the “Company”, “Argonaut Gold” or “Argonaut”) is pleased to announce updated Mineral Reserves at its El Castillo Complex, which is made up of the El Castillo and San Agustin Mines in Durango, Mexico, and its La Colorada Mine in Sonora, Mexico as of July 1, 2017.  The El Castillo Mineral Reserve increased approximately 74% from December 31, 2016 to July 1, 2017, primarily due to the acquisition of, and exploration success on, the San Juan mineral concession that was acquired in February of 2017.  The Mineral Reserves at the San Agustin Mine and the La Colorada Mine are maiden Mineral Reserves, as the Company had previously reported Mineral Resources only. 

The Company has filed two National Instrument (“NI”) 43-101 Technical Reports on www.sedar.com and Argonaut’s website www.argonautgold.com for the El Castillo Complex and the La Colorada Mine dated March 27, 2018, which include life-of-mine plans that illustrate annual production profiles slightly above Argonaut’s production guidance.  However, the Company reaffirms its previously reported three-year production guidance given its operating experience and weather-related challenges historically associated with low-grade, highly variable heap leach operations (see press release dated January 16, 2018 for Argonaut’s Three-Year Production Outlook).  The Company intends to provide further updates to its Mineral Reserves net of depletion through mining activities between July 1, 2017 and December 31, 2017 in its Annual Information Form, which will be filed on or before April 2, 2018.

Pete Dougherty, President & CEO stated: “We significantly increased our Mineral Reserves and mine life at El Castillo through the purchase of, and exploration success on, the adjacent San Juan mineral concession. Furthermore, we feel we have more opportunity at El Castillo in the future with approximately an additional 220,000 gold ounces in Measured and Indicated Mineral Resource above and beyond the Mineral Reserve.  With San Agustin now also having achieved commercial production, the El Castillo Complex boasts a Proven and Probable Mineral Reserve of 1.3 million gold ounces and 26.2 million silver ounces and across our Mexico operations we now have over 1.7 million gold ounces of Mineral Reserves.  At La Colorada, we continue to demonstrate our ability to consistently replace the ounces we deplete annually through mining due to our successful exploration programs.”

The El Castillo Complex consists of the El Castillo Mine and the San Agustin Mine, which share nearby infrastructure and resources.  The Mineral Reserves and life-of-mine plans at July 1, 2017 demonstrate a mine life through the end of 2021 at El Castillo and through the end of 2025 at San Agustin.  Table 1 below illustrates the El Castillo Complex Mineral Reserve and Mineral Resource estimate:

(2) The Mineral Reserves for El Castillo and San Agustin, which together form the El Castillo Complex, assume metal prices of US$1,200/oz Au and US$17/oz Ag and a Mexican peso to US dollar exchange rate of 19:1.  The Mineral Reserves were estimated by Argonaut and audited by Bret Swanson, BE (Min) MMSAQP, of SRK Consulting (U.S.), Inc., who is a Qualified Person under NI 43-101.
(3) The Measured and Indicated Mineral Resources and Inferred Mineral Resource for El Castillo and San Agustin, which together form the El Castillo Complex, assume metal prices of US$1,400/oz Au and US$20/oz Ag and were estimated by Argonaut and reviewed by Michael J.

Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include changes in market conditions, variations in ore grade or recovery rates, risks relating to international operations, fluctuating metal prices and currency exchange rates, changes in project parameters, the possibility of project cost overruns or unanticipated costs and expenses, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated.  Although Argonaut has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended.  There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.  Argonaut undertakes no obligation to update forward-looking statements if circumstances or management’s estimates or opinions should change except as required by applicable securities laws.  The reader is cautioned not to place undue reliance on forward-looking statements. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking statements to the extent they involve estimates of the mineralization that will be encountered if the property is developed.  Comparative market information is as of a date prior to the date of this document.
