Financial Results - Second Quarter 2021
Record quarterly revenue was $120.2 million for the second quarter of 2021, an increase from $58.0 million for the second quarter of 2020. During the second quarter of 2021, the Company sold 63,000 gold ounces at an average realized price per ounce of $1,812, compared to 32,707 gold ounces sold at an average realized price per ounce of $1,713 during the same period of 2020. Gold ounces sold for the second quarter of 2021 increased 93% compared to the same period in 2020, primarily due to increased production and gold sales at all Mexican operations due to a temporary two-month suspension of mining, crushing and stacking activities during the onset of the COVID-19 pandemic in response to the Mexican Federal Government decree during the second quarter of 2020 and the acquisition of the Florida Canyon mine on July 1, 2020.

Net income for the second quarter of 2021 was $21.8 million or earnings per basic share of $0.07, an increase from a net loss of $7.7 million or loss per basic share of $0.04 for the second quarter of 2020.

Adjusted net incomeⁱⁱ for the second quarter of 2021 was $24.4 million or $0.08 per basic share, an increase from adjusted net incomeⁱⁱ of $8.5 million or $0.05 per basic share for the second quarter of 2020.

Cash flows from operating activities before changes in non-cash operating working capital totaled $39.3 million during the second quarter of 2021, an increase from $11.8 million in the second quarter of 2020. The 234% increase in cash flow compared to the same period last year was primarily related to increased production and gold sales from all Mexican operations due to the two month suspension for COVID-19 during the second quarter of 2020, the acquisition of the Florida Canyon mine on July 1, 2020 and a higher average realized gold price.

Financial Results - First Half 2021
Revenue for the six months ended June 30, 2021 was $225.5 million, an increase from $124.5 million for the six months ended June 30, 2020. During the first half of 2021, gold ounces sold totaled 119,727 at an average realized price per ounce of $1,788, compared to 72,876 gold ounces sold at an average realized price per ounce of $1,642 during the same period of 2020. Gold ounces sold for the six months ended June 30, 2021 increased 64% compared to the same period in 2020 primarily due to increased production and gold sales at all Mexican operations due to the two month suspension for COVID-19 during the second quarter of 2020 and the acquisition of the Florida Canyon mine on July 1, 2020.

Net income for the six months ended June 30, 2021 was $48.8 million or earnings per basic share of $0.16, an increase from a net loss of $17.2 million or loss per basic share of $0.10 for the six months ended June 30, 2020.

Adjusted net incomeⁱⁱ for the six months ended June 30, 2021 was $32.2 million or adjusted earnings per basic shareⁱⁱ of $0.11, an increase from adjusted net incomeⁱⁱ of $16.9 million or adjusted earnings per basic shareⁱⁱ of $0.09 for the six months ended June 30, 2020.

Cash flows from operating activities before changes in non-cash operating working capital totaled $67.0 million in the six months ended June 30, 2021, an increase from $26.5 million in the six months ended June 30, 2020. The 153% increase in cash flow compared to the same period last year was primarily related to increased production and gold sales from all Mexican operations due to the two month suspension for COVID-19 during the second quarter of 2020, the acquisition of the Florida Canyon mine on July 1, 2020 and a higher average realized gold price.

Operational Results - Second Quarter 2021
During the second quarter 2021, the Company achieved record quarterly production of 63,749 GEOs at a cash cost of $876 per gold ounce sold and all-in sustaining cost ("AISC") of $1,187 per gold ounce sold compared to 31,531 GEOs at a cash cost of $885 per gold ounce sold and AISC of $1,080 per gold ounce sold during the second quarter 2020 (see "Non-IFRS Measures" section). The 102% increase in GEO production was primarily related to increased production from all Mexican operations due to the two month suspension for COVID-19 during the second quarter of 2020 and the acquisition of the Florida Canyon mine on July 1, 2020. Cash costs per gold ounce sold were relatively flat compared to the same period in 2020. The 10% increase in AISC compared to the same period in 2020 is primarily related to the increased sustaining capital spend at the Florida Canyon mine, which was acquired on July 1, 2020.

SECOND QUARTER 2021 EL CASTILLO COMPLEX OPERATING STATISTICS

Summary of Production Results at the El Castillo Complex - Second Quarter 2021
During the second quarter of 2021, the El Castillo Complex produced 38% more GEOs at a cash cost per gold ounce sold 15% higher than during the second quarter of 2020. GEO production was higher at both the El Castillo and San Agustin mines, primarily related to increased production due to the two month suspension for COVID-19 during the second quarter of 2020. Cash cost per gold ounce sold were higher, as there were no costs associated with mining, crushing and stacking for two months during the second quarter of 2020 in response to the Mexican Federal Government decree.

SECOND QUARTER 2021 LA COLORADA OPERATING STATISTICS

Summary of Production Results at La Colorada - Second Quarter 2021
During the second quarter of 2021, the La Colorada mine produced 120% more GEOs at a cash cost per gold ounce sold 48% less than during the second quarter of 2020 (see "Non-IFRS Measures" section). Higher GEO production was primarily due to an 81% increase in gold grade and due to the two month suspension for COVID-19 during the second quarter of 2020. Lower cash cost per gold ounce sold was primarily due to the increase in gold grade, a 45% reduction in strip ratio and 126% more gold ounces sold.

SECOND QUARTER 2021 FLORIDA CANYON OPERATING STATISTICS

Summary of Production Results at Florida Canyon
As Argonaut did not own nor operate the Florida Canyon mine during the three and six months ended June 30, 2020, it is not making comparisons to the same period last year. Florida Canyon produced 13,798 GEOS, a 15% increase in GEO production compared to the previous quarter. Cash cost per gold ounce sold of $1,110 represent a 24% decrease compared to the previous quarter (see "Non-IFRS Measures" section). Higher GEO production and lower cash cost per gold ounce sold compared to the previous quarter are primarily related to a 13% reduction in strip ratio and higher recoveries partially offset by a 9% reduction in gold grade.

Argonaut has identified potentially significant operating cost savings once it can eliminate the re-handle on the back end of the secondary crushing by switching to a conveying and stacking system to transport crushed ore to the leach pads. All necessary regulatory approvals, including a modification to the existing Air Quality permit, to allow for the construction, installation and operation of a new conveying and stacking system were received during the second quarter of 2021 (see press release dated April 28, 2021), and the construction and installation of the new conveying and stacking system was completed by the end of July 2021. It is estimated that the new system will be ramped up to design capacity during the third quarter of 2021. The capital associated with the convey and stack project was included in Argonaut's 2021 capital guidance (see press release dated January 19, 2021).

Pete Dougherty commented: "All three mines in Mexico have met or exceeded our expectations over the first half of the year, leading to record quarterly production and revenue, as well as strong cash flow and earnings in the second quarter. We experienced improvements in both production and operating costs at Florida Canyon quarter-over-quarter and believe these improvements will continue as we ramp up the new conveying and stacking system to design capacity over the next couple months. We believe this new system will significantly reduce operating costs at Florida Canyon once it is ramped up to design specifications and, given the recovery cycle at Florida Canyon, we should start to see the benefits of this investment during the fourth quarter of this year. On a consolidated basis, we are well on our way to achieving our production and cost guidance."

Outlook

Argonaut is on track to achieve its 2021 consolidated production, cost and capital guidance. The table below outlines the first half of 2021 production and cost actuals compared to full year 2021 guidance:

2021 PRODUCTION AND COST GUIDANCE

The Magino construction project is tracking on schedule. During the three and six months ended June 30, 2021, the Company incurred $64.0 million and $103.2 million in costs, respectively, related to the construction of the Magino project that were capitalized to assets under construction. Of this amount incurred, the majority was for securing long lead time components for the mineral processing plant and for site development, camp construction and earthworks.

While the Magino construction project remains on schedule, Argonaut is currently reviewing the impacts of COVID-19, foreign currency exchange rates, contingencies, potential adjustments to the development plans and cost inflation to certain inputs related to the initial capital estimate (excluding ramp-up capital) which it believes will likely exceed the 15% last disclosed in the press release dated May 4, 2021.

Argonaut is currently working to optimize its life-of-mine plans. Following this work, the Company anticipates publishing updated National Instrument ("NI") 43-101 Technical Reports for the the El Castillo Complex (El Castillo and San Agustin mines) and the La Colorada mine by the end of 2021.

Argonaut also believes there is a potential opportunity to reduce the near term sustaining capital requirement at its La Colorada mine, primarily by deferring some of the capitalized stripping of the Veta Madre pit. While this evaluation is ongoing, early indications illustrate a mine plan that is generally neutral in terms of net present value but provides additional cash flow during 2021 and 2022. More information regarding a new mine plan at La Colorada will be provided concurrent with the publication of an updated NI 43-101 Technical Report, which is expected by the end of 2021.

Full year 2021 capital guidance has not changed. However, Argonaut now expects to invest approximately an additional $10 million at the Magino construction project and decrease capital spending at La Colorada by approximately $10 million during 2021. Updated 2021 capital guidance is provided below:

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", and "Adjusted earnings per share - basic" 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, unrealized (gains) losses on commodity 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. 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.
