Argonaut Gold Inc. Announces First Quarter Production of 55,516 Gold Equivalent Ounces

Cash Flow1 of $25 Million and Provides Magino Construction Project Update

TORONTO, May 11, 2022 - 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, 2022. For the first quarter 2022, the Company reports production of 55,516 gold equivalent ounces² ("GEO" or "GEOs"), revenue of $105.8 million, cash flow from operating activities before changes in non-cash operating working capital and other items of $25.1 million, net income of $5.6 million or earnings per basic share of $0.02, and adjusted net income³ of $8.2 million or adjusted earning per basic share³ of $0.03. All dollar amounts are expressed in United States dollars, unless otherwise specified (C$ refers to Canadian dollars).

Magino Project Capital
The Company also reports that following the appointment of Larry Radford to the position of President, CEO and Director on March 21, 2022, Argonaut initiated a review of the estimated cost to completion ("EAC") for the Magino construction project. While this review has not yet been finalized, the Company estimates that the updated EAC is likely to be approximately 15% higher than the previously reported EAC of C$800 million (see December 14, 2021 press release). At March 31, 2022, Argonaut had committed approximately C$605 million, had incurred approximately C$400 million, and estimates the project is approximately 50% complete.

Magino Project Schedule
The Magino construction project currently remains on schedule for first gold pour by March 31, 2023. Argonaut has very recently been advised that certain subcontractors at Magino are exposed to current and threatened labour actions, which may give rise to delays should such labour actions continue or commence. While the scope of such delays remain uncertain, these events are developing and to this point have not led to any change to the overall project schedule.

Magino Project Financing
Since mid-December 2021, Argonaut has been actively advancing financing and strategic alternatives to finance the previously announced funding shortfall to complete the Magino construction project. Both financing and strategic alternatives continue to advance, and the Company is cautiously optimistic it will conclude either a financing or strategic alternative prior to the end of the second quarter 2022 to be able to continue to advance the Magino construction project on schedule. In the event that neither a financing nor a strategic alternative is available promptly and upon acceptable terms, Argonaut may need to amend or adjust its plans for construction of the Magino project.

Larry Radford, President & CEO stated: "We were generally in line with our operational budget during the first quarter, which yielded over 55,000 GEOs and $25 million in cash flow. My focus since my appointment has been primarily on the Magino construction project. The mining industry is experiencing extraordinary cost pressures and Magino is no exception. We have looked at costs internally and with the assistance of outside experts and are looking at all aspects of the project to understand risks and opportunities. While the updated EAC is not yet finalized, we expect it is likely to be approximately 15% higher than the C$800 million estimated prior to my appointment. We continue to advance financing options in parallel with strategic alternatives and, in order to continue to advance the Magino construction project on schedule, our goal is to have a solution in place by the end of the second quarter 2022."

Financial Results - First Quarter 2022
Revenue for the first quarter of 2022 was $105.8 million, relatively in line with $105.3 million in the first quarter of 2021. During the first quarter of 2022, the Company sold 54,107 gold ounces at an average realized price per ounce of $1,874, compared to 56,727 gold ounces sold at an average realized price per ounce of $1,761 during the same period of 2021. Gold ounces sold for the first quarter of 2022 decreased 5% compared to the same period in 2021 primarily due to lower gold grades processed at La Colorada and lower recoveries at Florida Canyon due to an increase in run-of-mine ore, which yields a lower recovery than crushed ore.

Net income for the first quarter of 2022 was $5.6 million or earnings per basic share of $0.02, compared with net income of $27.0 million or earnings per basic share of $0.09 for the first quarter of 2021, primarily due to a $2.5 million loss on derivatives in the first quarter of 2022 compared to an $18.8 million gain on derivatives in the first quarter 2021 as well as higher operating costs.

Adjusted net income for the first quarter of 2022 was $8.2 million or $0.03 per basic share, an increase from adjusted net income of $7.0 million or $0.02 per basic share for the first quarter of 2021. (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section).

Cash flows from operating activities before changes in non-cash operating working capital and other items totaled $25.1 million during the first quarter of 2022, a slight decrease from $27.7 million in the first quarter of 2021, primarily due to higher operating costs.

Operational Results - First Quarter 2022
During the first quarter of 2022, the Company achieved production of 55,516 GEOs at a cash cost per gold ounce sold of $1,153 and all-in sustaining cost per gold ounce sold ("AISC") of $1,430 compared to 59,704 GEOs at a cash cost of $1,003 per gold ounce sold and an AISC of $1,318 during the first quarter 2021 (These are Non-IFRS Measures. Please see "Non-IFRS Measures" section). The 8% decrease in GEO production was primarily related to lower gold grades processed at La Colorada and lower recoveries at Florida Canyon due to processing more run-of-mine ore. Higher costs were primarily related to higher mining rates at El Castillo and La Colorada due to higher strip ratios, higher reagent costs across all operations and lower gold ounces sold.

FIRST QUARTER 2022 EL CASTILLO COMPLEX OPERATING STATISTICS

Summary of Production Results at the El Castillo Complex
During the first quarter of 2022, the El Castillo Complex produced 1% more GEOs at a cash cost per gold ounce sold 17% higher than during the first quarter of 2021 (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section). El Castillo produced 5% fewer GEOs at a cash cost per gold ounce sold 17% higher (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section), primarily due to a higher strip ratio and higher reagent costs. San Agustin produced 5% more GEOs, primarily due to higher recoveries, at a cash cost per gold ounce sold 17% higher (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section), primarily due to higher reagent costs.

FIRST QUARTER 2022 LA COLORADA OPERATING STATISTICS

Summary of Production Results at La Colorada
During the first quarter of 2022, the La Colorada mine produced 17% fewer GEOs at a cash cost per gold ounce sold 25% more than during the first quarter of 2021 (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section). Lower GEO production and higher costs were primarily due to a 17% reduction in gold grade processed and a 45% higher strip ratio, as mining transitions from the El Crestón pit to the Veta Madre pit. Costs were also higher due to higher reagent costs.

FIRST QUARTER 2022 FLORIDA CANYON OPERATING STATISTICS

Summary of Production Results at Florida Canyon
During the first quarter of 2022, the Florida Canyon mine produced 15% fewer GEOs at a cash cost per gold ounce sold 13% higher than during the first quarter of 2021 (This is a Non-IFRS Measure. Please see "Non-IFRS Measures" section). Lower GEO production and higher costs were primarily related to lower recoveries due to processing more run-of-mine ore, which yields a lower recovery, and higher reagent costs.

Guidance and Outlook
Argonaut maintains its 2022 production and cost guidance as outlined in the table below. Due to the current inflationary environment, the Company will continue to monitor inputs to its cost profile and make adjustments to cost guidance if and when appropriate.

2022 GEO Production and Cost Guidance

As Argonaut is currently advancing financing and strategic alternatives to fund the remainder of the Magino construction project, it intends to provide full year 2022 capital guidance after financing is in place. The largest component of the projected 2022 capital spend will be the Magino construction project where Argonaut forecasts it will invest approximately $340 million (C$424 million), which is subject to change pending the updated EAC, assuming financing is achieved promptly and upon acceptable terms. In the event that financing is not available promptly and upon acceptable terms, the Company may need to amend or adjust its plans for construction of the Magino project which would significantly impact the project's schedule and potentially increase project capital. Ultimate project costs may experience variation due to disruptions including those caused by COVID-19, the Russia/Ukraine war, weather, labour disruptions, a tight labour market, inflation and supply chain impacts.

Argonaut Gold First Quarter 2022 Operational and Financial Results Conference Call and Webcast:

The Company will host a conference call and webcast to discuss its first quarter ended March 31, 2022 operating and financial results at 9:00 am EDT on May 12, 2022.

The conference call and replay will be available from 12:00 pm EDT on May 12, 2022 until 11:59 pm EDT on May 19, 2022.

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 less foreign exchange impacts on deferred income taxes, foreign exchange (gains) losses, non-cash impairment write down (reversal) of work-in-process inventory, non-cash impairment write down (reversal) of mineral, properties, plant and equipment, unrealized (gains) losses on derivatives and care and maintenance expenses. 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.

The following table provides a reconciliation of production costs per the financial statements to cash cost per gold ounce sold:

AISC includes net cost of sales at the Company's mining operations, which forms the basis of the Company's cash cost per gold ounce sold. Additionally, the Company includes general and administrative, exploration, accretion and other expenses, and sustaining capital expenditures. Sustaining capital expenditures exclude all expenditures at the Company's pre-production, development stage, and advanced exploration stage projects and certain expenditures at the Company's operating sites that are deemed expansionary in nature.

The following table provides a reconciliation of AISC per gold ounce sold to the consolidated financial statements:

Adjusted net income and adjusted earnings per share - basic exclude a number of temporary or one-time items described in the following table, which provides a reconciliation of adjusted net income to the consolidated financial statements:

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 net debt calculation excludes the convertible debentures and lease liabilities, due to the nature of the obligations, in order to show the nominal undiscounted debt.

A reconciliation of net cash is provided below:
