Argonaut Gold Announces Q3 Production of 26,322 Gold Equivalent Ounces and Revised Guidance

TORONTO, ONTARIO--(Marketwired - Oct. 17, 2016) - Argonaut Gold Inc. (TSX:AR) ("Argonaut", "Argonaut Gold" or the "Company") reports production of 26,322 gold equivalent ounces ("GEOs") during the third quarter ended September 30, 2016 ("Q3"). The lower than anticipated production during the third quarter is primarily a result of two factors at the Company's El Castillo mine: higher than anticipated rainfall and changes in mine sequencing. Given the lower than planned production, the Company is adjusting its 2016 production guidance to between 115,000 and 120,000 GEOs (previously 130,000 to 135,000 GEOs). All dollars in this press release are expressed in U.S. dollars, unless otherwise noted.

During Q3, the Company produced 13,161 GEOs at its El Castillo mine and 13,161 GEOs at its La Colorada mine for a total of 26,322 GEOs.

At El Castillo, production at the operation was negatively affected by heavy rainfall during the period, which hampered both mining and crusher throughput. Unusually heavy rainfall during Q3 amounted to 344.5 millimetres versus 132.0 millimetres during the same period in 2015. In addition, the Company estimates that during 2016 it will have mined approximately 2.8 million tonnes of ore at an average grade of 0.23 grams gold per tonne that was not in the original 2016 mine plan. This ore is comprised of lower grade oxide, transition and higher grade sulphide material. While economic, the sulphide ore yields significantly lower recoveries. The additional ore tonnes have impacted mine sequencing which has delayed mining the higher grade oxide ore phases of the pit that had been planned to be mined during 2016 and therefore lowered production. This change will have a positive impact on 2017 production, as the Company originally had no oxide ore scheduled to be mined during 2017 in the life of mine plan ("LOM plan") (see Annual Information Form filed March 16, 2016 on but now anticipates mining approximately 60% oxide ore during 2017. Also during Q3, the CR2 crushing unit, relocated from La Colorada to El Castillo during August 2016, completed its ramp up to over 5,000 tonnes per day. This additional crushing should positively impact production during the fourth quarter 2016 and 2017 compared to the LOM plan.

At La Colorada, the Company continues to encounter more economic mineralized material than anticipated. While the Company is pleased to discover areas of economic low grade material, processing this material contributed to lower gold production compared to the planned processing of higher grade material during 2016. These low grade gains were partially offset by higher than budgeted throughput and a reduced stripping ratio.

Pete Dougherty, President and CEO, stated: "Heavy rainfall during the quarter at El Castillo made it extremely difficult to hit our mining and throughput targets. Also at El Castillo, due to the revision of mine sequencing, we have mined much lower grade oxide and much more sulphide ore than planned in 2016 which will lead to more oxide production in 2017. Now that the rainy season is past us, we are mining the higher grade oxide ore from phase six. We believe that the fourth quarter should improve in terms of ore placements -- particularly with the additional crushing capacity.

"At La Colorada, it is important to note that we have not changed our cutoff grades. Much of what was classified as waste in our mine model turned out to be above our cutoff grade and is now considered economic. This positive development increases our tonnages, lowers the strip ratio and extends mine life. Additionally, the recent drilling at the El Creston deposit showed encouraging results as we begin preparing this pit for production."

Mineral resources referenced herein are not mineral reserves and do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. The mineral resource estimates may include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.

The Company cautions that a PEA is preliminary in nature and that it relies upon mineral resource estimates which have the considerations noted above applied to them. There is no certainty that a PEA will be realized or that any of the resources will ever be upgraded to reserves.
