Argonaut Gold Announces 43% Increase in Mineral Reserves to 6.8 Million Contained Gold Ounces and 26% Increase in Measured and Indicated Mineral Resources to 13.1 Million Contained Gold Ounces Year-over-Year

March 29, 2021

TORONTO, March 29, 2021 /CNW/ - Argonaut Gold Inc. (TSX: AR) (the "Company", "Argonaut Gold" or "Argonaut") is pleased to announce it has increased its Mineral Reserves by 43% and its Measured and Indicated ("M&I") Mineral Resources by 26% from December 31, 2019 to December 31, 2020.  The majority of the increase to Mineral Reserves and Mineral Resources are in relation to the acquisition of Alio Gold Inc. (see press release date July 1, 2020).  Both the San Agustin mine and the La Colorada mine increased their respective Mineral Reserves net of depletion, while the Florida Canyon mine essentially replaced the Mineral Reserves that were depleted.  Mineral Reserves and Mineral Resources were not updated at the Company's non-producing projects.

The following table shows the gold and silver Mineral Resources and Mineral Reserves at December 31, 2020. Mineral Resources are not Mineral Reserves.  Mineral Resources hold intrinsic economic interest, which has been identified and estimated through exploration and sampling and within which Mineral Reserves may subsequently be defined.  There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves.   Measured and Indicated Mineral Resources listed below are inclusive of Mineral Reserves.

Footnotes from the Mineral Reserves and Mineral Resources statement apply.  M&I Mineral Resources are inclusive of Mineral Reserves. The 2020 Mineral Resources are based on a gold price of $1,800 per ounce and 2019 Mineral Resources were based on a gold price of $1,600 per ounce. Mineral Resources were not calculated in 2019 at the Florida Canyon Mine by Alio at the end of 2019.

Pete Dougherty, President & CEO commented: "The replacement of depleted Mineral Reserves is a key part of our business strategy.  Our strategy is to harvest cash from these operations, replace depleted Mineral Reserves to extend mine lives and focus on executing on our growth projects to transition Argonaut from a high-cost junior producer with relatively short mine lives to a lower cost intermediate producer with much longer mine lives."

Cautionary Note Regarding Forward-looking Statements
This press release contains certain "forward-looking statements" and "forward-looking information" under applicable Canadian securities laws concerning the business, operations and financial performance and condition of Argonaut Gold Inc. ("Argonaut" or "Argonaut Gold"). Forward-looking statements and forward-looking information include, but are not limited to statements with respect to the realization of mineral reserve estimates; the timing and amount of estimated future production; costs of production; and financial impact of completed acquisitions; the benefits of the development potential of the properties of Argonaut; the future price of gold, copper, and silver; the estimation of mineral reserves and resources; success of exploration activities; and currency exchange rate fluctuations; permitting and legal processes in relation to mining permitting and approvals; estimated production and mine life of the various mineral projects of Argonaut; the ability to obtain permits for operations; and synergies. Except for statements of historical fact relating to Argonaut, certain information contained herein constitutes forward-looking statements. Forward-looking statements are frequently characterized by words such as "plan," "expect," "project," "intend," "believe," "anticipate", "estimate" and other similar words, or statements that certain events or conditions "may", "should" or "will" occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of Argonaut and there is no assurance they will prove to be correct.

Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include variations in ore grade or recovery rates, changes in market conditions, risks relating to the availability and timeliness of permitting and governmental approvals; 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.

These factors are discussed in greater detail in Argonaut's most recent Annual Information Form and in the most recent Management's Discussion and Analysis filed on SEDAR, which also provide additional general assumptions in connection with these statements. Argonaut cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail. Argonaut believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this press release should not be unduly relied upon. These statements speak only as of the date of this press release.

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.
