CEO Commentary
Pete Dougherty, President and CEO stated: "During 2020, we put the Company in a fantastic position to execute on our transition strategy from a short mine life, high-cost junior producer to a long mine life, lower cost intermediate producer through the permitting and financing achievements for the Magino project in Ontario, Canada, leading to a construction decision, and the acquisition of the Florida Canyon mine in Nevada, USA. As we look to 2021, we are focused on continuing to execute on this strategy now that the pieces are in place to do so, as well as the exploration upside at the Magino and the Florida Canyon districts."

The table below outlines the Company's performance compared to updated full-year guidance:

The Company achieved its updated GEO production, cash cost, AISC and capital guidance. The Magino project was approved for construction in October 2020 and a fixed-bid contract covering approximately 40% of the initial project capital was announced early January 2021. Fourth quarter 2020 spending on Magino construction capital was approximately $19.3 million, with the balance of the estimated 2020 spend, primarily related to the timing of procurement of long-lead time equipment, shifting from December 2020 to January 2021 given the timing of execution of the fixed-bid contract.

Financial Results - Fourth Quarter 2020
Record quarterly revenue was $100.8 million for the fourth quarter of 2020, an increase from $72.1 million for the fourth quarter of 2019. During the fourth quarter of 2020, gold ounces sold totaled 51,497 at an average realized price per ounce of $1,882, compared to 47,073 gold ounces sold at an average price per ounce of $1,484 during the same period of 2019. Gold ounces sold for the fourth quarter of 2020 increased compared to the same period in 2019 primarily due to the addition of the gold ounces sold from the Florida Canyon mine offset by decreases in gold ounces produced and sold at the El Castillo mine mostly related to the change from processing crushed ore to run-of-mine ore and the San Agustin mine related to lower gold grades.

Income from continuing operations for the fourth quarter of 2020 was $20.3 million or $0.07 per basic or diluted share compared to a loss from continuing operations of $107.5 million or $0.60 per share in the fourth quarter of 2019. Loss from discontinued operations for the fourth quarter of 2020 was $2.3 million as a result of the Ana Paula project being classified as a held-for-sale asset as at December 31, 2020 and as a discontinued operation for 2020. Net income for the fourth quarter of 2020 was $18.0 million or $0.06 per basic or diluted share compared to a net loss of $107.5 million or $0.60 loss per share for the fourth quarter of 2019. The increase is net income is primarily related to record quarterly revenue of $100.8 million during the fourth quarter 2020 and the impact of the non-cash impairment of $111.0 million associated with the San Antonio project during the fourth quarter 2019.

Record quarterly cash flow from operating activities before changes in non-cash operating working capital was $39.5 million. During the fourth quarter of 2020, cash increased by $36.3 million due primarily to $31.5 million of cash flows from operations (including changes in non-cash operating capital and other items), $54.0 million net proceeds from the convertible debentures, and $8.2 million from issuance of flow-through shares, partially offset by $34.8 million of capital expenditures incurred and the repayment of $22.1 million of debt, as compared to the fourth quarter of 2019 in which cash increased by $3.2 million due primarily to $17.7 million of cash flows from operations, partially offset by $11.2 million of capital expenditures incurred and the repayment of $4.0 million of debt.

Financial Results - 2020
Record annual revenue for 2020 was $319.7 million, an increase from $268.9 million for 2019. Gold ounces sold totaled 172,024 at an average realized price per ounce of $1,789 (compared to 187,802 gold ounces sold at an average price per ounce of $1,390 for 2019). Gold ounces sold for 2020 decreased compared to the same period in 2019, primarily as a result of the temporary suspension of mining, crushing and stacking activities in response to the Mexican Federal Government decree related to the COVID-19. Other factors include a decrease in gold ounces sold at the La Colorada and San Agustin mines due to a reduction in ore grades and a decrease in gold ounces sold at the El Castillo mine due to the change from processing crushed ore to run-of-mine ore, offset by an addition of the gold ounces sold from the Florida Canyon mine.

Income from continuing operations for 2020 was $17.9 million or $0.08 per basic or diluted share compared to a loss from continuing operations of $93.1 million or $0.52 per share in 2019. Loss from discontinued operations for 2020 was $3.7 million as a result of the Ana Paula project, which has been classified as a held-for-sale asset as at December 31, 2020 and as a discontinued operation for 2020. Net income for 2020 was $14.2 million or $0.06 per basic or diluted share compared to a net loss of $93.1 million or $0.52 loss per share for the fourth quarter of 2019. The increase is net income is primarily related to record annual revenue of $319.7 million in 2020 and the impact of the non-cash impairment of $111.0 million associated with the San Antonio project in 2019.

Record annual cash flow from operating activities before changes in non-cash operating working capital was $95.0 million. During 2020, cash increased by $175.5 million due primarily to $111.7 million of cash flows from operations (including changes in non-cash operating working capital and other items), $89.4 million from the public offering of shares, $54.0 million from the convertible debentures, and $8.2 million from issuance of flow-through shares, partially offset by $28.7 of debt repayments and $63.9 million of capital expenditures incurred, as compared to 2019 in which cash increased by $23.4 million due primarily to $74.8 million of cash flows from operations, partially offset by $51.8 million of capital expenditures incurred.

Operating Results - Fourth Quarter 2020
During the fourth quarter of 2020, the Company achieved record quarterly production of 56,985 GEOs at a cash cost per gold ounce sold of $910 and an all-in sustaining cost ("AISC") per gold ounce sold of $1,189, compared to 47,521 GEOs at a cash cost of $1,441 per gold ounce sold and an AISC per gold ounce sold of $1,690 during the fourth quarter of 2019 (see "Non-IFRS Measures" section). Higher GEO production is primarily related to the addition of the Florida Canyon mine following the acquisition of Alio on July 1, 2020. Lower cash cost per gold ounce sold and AISC per gold ounce sold was primarily due to an impairment of work-in-progress inventory of $20.1 million at the El Castillo Complex and $12.1 million at the La Colorada mine in the fourth quarter of 2019, which increased the cash cost and AISC during the fourth quarter of 2019.

Operating Results - 2020
During 2020, the Company achieved production of 179,003 GEOs at a cash cost per gold ounce sold of $936 and an AISC per gold ounce sold of $1,244, compared to 186,615 GEOs at a cash cost per gold ounce sold of $1,041 and AISC per gold ounce sold of $1,299 in 2019 (see "Non-IFRS Measures" section). Lower GEO production in 2020 is primarily related to the change from processing crushed ore to run-of-mine ore at the El Castillo mine and the two month suspension of mining, crushing and stacking activities at all Mexican operations due to COVID-19. Lower production was partially offset by the addition of the Florida Canyon mine following the Alio acquisition on July 1, 2020. Lower cash cost per gold ounce sold was primarily related to the inventory adjustment recorded during the fourth quarter of 2019.

Pete Dougherty commented: "I'm very pleased with how our organization worked with the various levels of the Mexican government to assist in the development of COVID-19 protocols for the Mexican mining industry that prioritize the safety and well-being of our workforces and the communities in which we operate. While the two month temporary suspension of mining, crushing and stacking operations we experienced in 2020 clearly had an impact on all Mexican operations, we successfully and safely re-started operations and have experienced very minimal COVID-19 infections throughout our Mexican workforce due to our strict protocols."

FOURTH QUARTER AND FULL YEAR 2020 EL CASTILLO COMPLEX OPERATING STATISTICS

Summary of Production Results at the El Castillo Complex - Fourth Quarter 2020
During the fourth quarter of 2020, the El Castillo Complex produced 11% fewer GEOs at a cash cost per gold ounce sold 42% less than during the fourth quarter of 2019. Lower GEO production was primarily due to a 33% reduction in gold grades loaded to the leach pads associated with the change from crushed ore to run-of-mine ore, which lowered unit costs and allowed for lower grade ore to become economic. This was partially offset by a 21% reduction in overall waste to ore strip ratio. Lower cash cost per gold ounce sold was primarily related to an inventory write-down in the fourth quarter of 2019.

El Castillo produced 10% fewer GEOs at a cash cost per gold ounce sold 58% less than during the fourth quarter of 2019. At El Castillo, 54% more ore tonnes were mined compared to the fourth quarter of 2019, partially to offset the 52% reduction in gold grade during this period, as lower grades became economic with the change from crushed ore to run-of-mine ore due to the associated reduction in unit costs, and also because during the fourth quarter of 2019, productivity was slowed due to water in the pit.

San Agustin produced 11% fewer GEOs at a cash cost per gold ounce sold 14% less than during the fourth quarter of 2019. At San Agustin, ore tonnes mined increased by 14% compared to the fourth quarter of 2019, primarily due to crusher throughput averaging better than 31,000 tonnes per day following the ramp up of the crusher expansion from 20,000 tonnes per day to 30,000 tonnes per day, which was completed in 2019, partially offset by 11% lower gold grade.

Summary of Production Results at the El Castillo Complex - 2020
During 2020, the El Castillo Complex produced 16% fewer GEOs at a cash cost per gold ounce sold 19% less compared to 2019. Lower GEO production was primarily due to the two-month suspension of mining, crushing and stacking activities and lower production at El Castillo associated with the change from processing crushed ore to run-of-mine ore.

El Castillo produced 31% fewer GEOs at a cash cost per gold ounce sold 24% less compared to 2019. El Castillo experienced a 34% reduction in cost per tonne processed compared to 2019 by eliminated crushing early in 2020 and switching to run-of-mine ore processing.

San Agustin produced 1% fewer GEOs at a cash cost per gold ounce sold 10% less compared to 2019. San Agustin experienced a 10% reduction in cost per tonne processed compared to 2019, primarily due to optimizing crushing and stacking rates to available solution capacity following the crusher expansion from 20,000 tonnes per day to 30,000 tonnes per day, which was completed by the end of 2019.

FOURTH QUARTER AND FULL YEAR 2020 LA COLORADA OPERATING STATISTICS

Summary of Production Results at La Colorada - Fourth Quarter 2020
During the fourth quarter of 2020, the La Colorada mine produced 15% more GEOs at a cash cost per gold ounce sold 53% less than during the fourth quarter of 2019. Higher GEO production was primarily due to a 17% increase in crushed tonnes to the leach pads, as La Colorada experienced productivity challenges during the fourth quarter of 2019 due to water in the pit. Lower cash cost per gold ounce sold was primarily due to an inventory write-down during the fourth quarter of 2019. Total tonnes mined decreased 23% compared to 2019, as the waste to ore strip ratio was 44% lower, and ore tonnes mined were set at the optimal rate to meet crusher throughput and solution capacity.

Summary of Production Results at La Colorada - 2020
During 2020, the La Colorada mine produced 16% less GEOs at a cash cost per gold ounce sold 11% less compared to 2019. Lower GEO production was primarily due to the two-month suspension of mining, crushing and stacking activities. La Colorada experienced a 4% reduction in cost per tonne processed compared to 2019, primarily due to higher daily crusher throughput rates and better productivity after experiencing challenges with water in the pit during the second half of 2019.

FOURTH QUARTER AND FULL YEAR 2020 FLORIDA CANYON OPERATING STATISTICS

Summary of Production Results at Florida Canyon
As the Company's has only two quarters of operating history at Florida Canyon following the acquisition of Alio, the Company is not making comparisons to previous periods. Florida Canyon produced 11,294 GEOs at a cash cost of $1,335 per gold ounce sold during the fourth quarter of 2020 (see "Non-IFRS Measures" section).

During the fourth quarter 2020, the Company eliminated a re-handle of ore prior to the primary crusher by adding a drop box to the design. Haul trucks can now dump ore directly into a box that feeds into the primary crusher. Prior to the addition of the drop box, the primary crusher had to be loader fed, which required haul trucks to dump ore on the ground, a dozer to push the ore into a pile and a loader to feed to the primary crusher. Currently, once ore goes through the primary and secondary crushers, it is loaded into haul trucks with a front-end loader and delivered to the leach pads via haul trucks.

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. To achieve this, a minor modification to the Air Quality permit (Plan of Operations) is required. While Argonaut views this to be a minor modification, the current US Federal administration has recently signed an executive order that requires all modifications, however minor, to be approved by one of four positions located in Washington, D.C. Argonaut is currently working to determine how the current signing authority process will impact all minor permit modifications, including the modification required to optimize the Florida Canyon mine. Argonaut believes the modification it is seeking will reduce greenhouse gas emissions at Florida Canyon, as the conveying and stacking system would be operated on grid power thus eliminating the need to run diesel haul trucks from the crusher to the leach pads.

Pete Dougherty commented: "Since closing the acquisition of the Florida Canyon mine on July 1, 2020, the first three months was spent by the Argonaut team getting to know the Florida Canyon team to gain a better understanding of the challenges and opportunities at the mine. The second three months were spent initiating changes to allow for a more efficient and lower cost operation, such as completing the permitting to allow solution to the newly constructed leach pad, upgrading equipment, adding the drop box at the primary crusher and preparing and submitting the minor modification to the existing permit to allow us to automate transporation of crushed ore to the leach pads through a conveying and stacking sytem. 2021 will be about finalizing the changes necessary to take Florida Canyon to a larger production profile at lower operating costs."

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 plus the total impact of impairment write downs related to work-in-process inventory less silver sales divided by gold ounces sold. Adjusted cash cost per gold ounce sold is equal to production costs plus only the impact of non-cash impairment write downs related to the net realizable value of work-in-process inventory less silver sales divided by gold ounces sold. AISC per gold ounce sold is equal to production costs plus the total impact of impairment write downs related to work-in-process inventory less silver sales plus general and administrative, exploration, accretion and other expenses and sustaining capital expenditures divided by gold ounces sold. Adjusted AISC per gold ounce sold is equal to production costs plus only the impact of non-cash impairment write downs related to the net realizable value of work-in-process inventory 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 loss less foreign exchange impacts on deferred income taxes, foreign exchange (gains) losses, impairment write down (reversal) of work-in-process inventory, proceeds from legal proceedings, non-cash impairment loss (reversal) on certain non-current assets, unrealized (gains) losses on commodity derivatives and other operating expense (income). 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.
