Quarterly Production of 41,536 Gold Equivalent Ounces and Net Cash¹ Increase of $6.0 Million

TORONTO, May 12, 2020 - Argonaut Gold Inc. (TSX: AR) (the "Company", "Argonaut Gold" or "Argonaut") is pleased to announce its operating and financial results for the first quarter ended March 31, 2020. The Company reports quarterly production of 41,536 gold equivalent ounces2 ("GEO" or "GEOs"), a quarterly net cash¹ increase of $6.0 million, cash flow from operating activities before changes in operating working capital of $14.8 million, net loss of $9.5 million or loss per share of $0.05 and adjusted net income¹ of $8.4 million or adjusted earnings per share¹ of $0.05. All dollar amounts are expressed in United States dollars, unless otherwise specified (C$ refers to Canadian dollars).

CEO Commentary
Pete Dougherty, President and CEO stated: "We are starting to see the benefits of the operational changes we implemented in late 2019 and early 2020 and expect to see the positive impact of these benefits throughout the balance of the year. During the quarter, we delivered strong cash flow that allowed us to reduce our accounts payable balance by $10 million, reduce our debt by $3 million, invest nearly $13 million in capital projects and still increase our cash balance by $3 million. While mining, crushing and stacking operations were ceased in early April due to the COVID-19 restrictions in Mexico, we are preparing to restart these activities on May 18, 2020. The safety and security of our workforce and the communities in which we operate is paramount and we are going above and beyond the government requirements for re-opening full operations. Given the nature of heap leach operations, metal production and sales have not been impacted to date. Also, since we were ahead on our leach pad construction year-to-date, we will have the opportunity to quickly ramp production back up to planned levels given our ability to place ore very close to plastic."

Key operating and financial statistics for the first quarter of 2020 are outlined in the following table:

Financial Results – First Quarter 2020
Revenue for the three months ended March 31, 2020 was $66.6 million, a decrease from $73.9 million for the three months ended March 31, 2019. During the first quarter of 2020, gold ounces sold totaled 40,169 at an average realized price per ounce of $1,585, compared to 54,779 gold ounces sold at an average realized price per ounce of $1,309 during the same period of 2019. Gold ounces sold for the three months ended March 31, 2020 decreased compared to the same period in 2019 primarily due to a decrease in gold ounces produced at the El Castillo mine due to a decrease in ore tonnes to leach pads and at the La Colorada mine due to a decrease in grade.

Production costs for the first quarter of 2020 were $41.6 million, a decrease from $51.1 million in the first quarter of 2019, primarily due to a decrease in gold ounces sold. Cash cost per gold ounce sold (see "Non-IFRS Measures" section) was $967 in the first quarter of 2020, an increase from $892 in the same period of 2019, primarily due to an increase in cash cost per gold ounce sold at the El Castillo and La Colorada mines due to lower ounces sold at both mines and lower grades processed at the La Colorada mine. The depreciation, depletion and amortization ("DD&A") expense included in cost of sales for the first quarter of 2020 totaled $11.1 million, a decrease from $11.9 million in the first quarter of 2019, due to a decrease in gold ounces sold offset by the increase in average DD&A expense per ounce due to the significant capital additions during 2019.

General and administrative expenses for the first quarter of 2020 were $4.1 million, an increase from $3.8 million for the same period of 2019, primarily due to Alio acquisition-related costs.

Losses on derivatives for the first quarter of 2020 were $1.8 million, compared to gains of $0.2 million in the first quarter of 2019, primarily due to unrealized mark-to-market losses on the Company's outstanding zero-cost collar commodity contracts entered into in August 2019.

Other expense for the first quarter of 2020 was $5.9 million, a decrease from other income of $0.6 million in the first quarter of 2019, due to differences in foreign currency translation effects as a result of the significant weakening of the Mexican peso and Canadian dollar against the US dollar during the quarter.

Income tax expense for the first quarter of 2020 was $11.2 million, compared to $3.9 million in the same period of 2019. The change is due to the foreign exchange effects of the weakening Mexican peso on the calculation of deferred taxes during the first quarter of 2020.

Net loss for the first quarter of 2020 was $9.5 million or $0.05 per basic share, a decrease from net income of $4.1 million or $0.02 per basic share for the first quarter of 2019. Adjusted net income for the first quarter of 2020 was $8.4 million or adjusted earnings per basic share of $0.05, an increase from adjusted net income of $2.4 million or adjusted earnings per basic share of $0.01 for the first quarter of 2019 (see "Non-IFRS Measures" section).

Operational Results – First Quarter 2020
During the first quarter 2020, the Company achieved quarterly production of 41,536 GEOs at a cash cost of $967 per gold ounce sold and all-in sustaining cost of $1,323 per gold ounce sold compared to 54,169 GEOs at a cash cost of $892 per gold ounce sold and an all-in sustaining cost of $1,123 per gold ounce sold during the first quarter 2019 (see "Non-IFRS Measures" section).

The El Castillo Complex produced 28,508 GEOs at a cash cost of $941 per gold ounce sold during the first quarter of 2020 versus 38,067 GEOs at a cash cost of $867 per gold ounce sold during the first quarter of 2019 (see "Non-IFRS Measures" section). Higher cash costs per ounce are related to lower gold ounces sold, which was driven by a planned reduction in recovery rates at the El Castillo mine due to the processing of a higher percentage of transitional and sulphide ores and switching to run-of-mine ore versus crushed ore.

La Colorada produced 13,028 GEOs at a cash cost of $1,021 per gold ounce sold during the first quarter of 2020 compared to 16,102 GEOs at a cash cost of $952 per gold ounce sold during the first quarter of 2019 (see Non-IFRS Measures section). Higher cash cost per ounce is due to lower gold ounces sold as a result of lower gold grades processed.

Pete Dougherty commented: "We achieved higher than expected production at the El Castillo mine, similar production to plan at the La Colorada mine and lower than planned production at the San Agustin mine. On a consolidated basis, first quarter production was generally in line with expectations. Costs per ounce were higher than anticipated since a higher portion of the quarterly production was from El Castillo and a lower portion of production was from San Agustin – our highest and lowest cost operations, respectively. At the El Castillo Complex, we have made positive strides in lowering our unit cost per tonne processed and this will continue to be a focus of the organization."

FIRST QUARTER 2020 EL CASTILLO COMPLEX OPERATING STATISTICS

Summary of Production Results at the El Castillo Complex
During the first quarter 2020, the El Castillo Complex produced 25% fewer GEOs at a cash cost per gold ounce sold (see "Non-IFRS Measures" section) 9% higher compared to the first quarter 2019. Lower production was driven by a planned reduction in recovery rates at the El Castillo mine due to the processing of a higher percentage of transitional and sulphide ores and the switch to run-of-mine ore versus crushed ore. Higher cash costs were primarily due to lower gold ounces sold. On a unit cost basis, El Castillo and San Agustin experienced a cost per tonne processed reduction of 14% and 15%, respectively, during the first quarter of 2020 compared to the first quarter of 2019. San Agustin averaged nearly 30,000 tonnes per day through the crushing and stacking circuit during the first quarter of 2020 following the expansion of this circuit from 20,000 tonnes per day to 30,000 tonnes per day in 2019. This led to an inventory build on the heap leach pad at San Agustin during the first quarter that is expected to be drawn down over the course of 2020.

FIRST QUARTER 2020 LA COLORADA OPERATING STATISTICS

Summary of Production Results at La Colorada
During the first quarter 2020, La Colorada produced 19% fewer GEOs at a cash cost per gold ounce sold (see "Non-IFRS Measures" section) 7% higher compared to the first quarter 2019. Lower production was primarily related to lower grades processed, as the Company experienced difficulty meeting planned mining rates due to increased water at the bottom of the pit. This led to a reduction of phase two ore tonnes, which were supplemented with ore from low-grade stockpiles in order to maintain crusher feed. The Company has added additional pumping at La Colorada to confront the water challenges in the pit. The Company anticipates production at La Colorada will dip lower in the second quarter of 2020 compared to the first quarter of 2020 since mining and placement of ore tonnes from phase two (the bottom) of the El Créston pit is currently behind schedule. The Company anticipates stronger production during the second half of 2020, as mining returns to the upper benches of the El Créston pit. Higher cash cost per ounce was primarily due to lower gold ounces sold as a result of lower grades processed.

Alio Transaction
The Company mailed and filed the joint-circular in connection with its friendly, at-market merger with Alio on April 22, 2020 and will hold its Annual and Special Meeting in a virtual-only format on May 20, 2020. Leading proxy advisory firms, Institutional Shareholder Services Inc. (ISS) and Glass, Lewis & Co., have both recommended that shareholders vote FOR the transaction. The Company anticipates the transaction will close in June 2020.

COVID-19 Update
As the municipalities near the Company's operations have low or no reported COVID-19 transmission, Argonaut is preparing to restart mining, crushing and stacking operations on May 18, 2020 and anticipates it will take approximately one week to fully ramp up to normal run rates. As Argonaut operates heap leach mines, processing of leach solution and metal production and sales have continued since the original government decree to cease non-essential businesses on March 31, 2020. Argonaut has developed and implemented protocols for the protection of its workforce and communities where it operates.

Potential Timing of Guidance Update
Due to the uncertainty with respect to the future developments of the COVID-19 outbreak, including the duration, severity and scope of the outbreak, Argonaut withdrew its full year guidance across all operations on April 1, 2020. The Company currently anticipates it will provide updated guidance following the closing of the Alio transaction but cautions that this timing is subject to change depending on future developments of the COVID-19 outbreak.

Non-IFRS Measures
The Company has included certain non-IFRS measures including "Cash cost per gold ounce sold", "All-in sustaining cost per gold ounce sold", "Adjusted net income", "Adjusted earnings per share – basic" and "Net cash" in this press release to supplement its financial statements which are presented in accordance with International Financial Reporting Standards ("IFRS"). Cash cost per gold ounce sold is equal to production costs less silver sales divided by gold ounces sold. All-in sustaining cost per gold ounce sold is equal to production costs less silver sales plus general and administrative, exploration, accretion and other expenses and sustaining capital expenditures divided by gold ounces sold. Adjusted net income is equal to net income (loss) less foreign exchange impacts on deferred income taxes, foreign exchange (gains) losses, non-cash impairment write down (reversal) of work-in-process inventory and unrealized (gains) losses on commodity derivatives. Adjusted earnings per share – basic is equal to adjusted net income divided by the basic weighted average number of common shares outstanding. Net cash is calculated as the sum of the cash and cash equivalents balance net of debt as at the statement of financial position date. The Company believes that these measures provide investors with an alternative view to evaluate the performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS. Therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Please see the management's discussion and analysis ("MD&A") for full disclosure on non-IFRS measures.

This press release should be read in conjunction with the Company's unaudited interim condensed consolidated financial statements for the three months ended March 31, 2020 and associated MD&A, for the same period, which are available from the Company's website, www.argonautgold.com, in the "Investors" section under "Financial Filings", and under the Company's profile on SEDAR at www.sedar.com.
