Argonaut Gold Announces Fourth Quarter and Full Year Financial and Operating Results, Provides 2020 Production, Cost and Capital Guidance

TORONTO, Feb. 24, 2020 - Argonaut Gold Inc. (TSX: AR) (the "Company", "Argonaut Gold" or "Argonaut") announces its financial and operating results for the fourth quarter and year ended December 31, 2019. The Company reports fourth quarter 2019 adjusted net income¹ of $2.7 million or adjusted earnings per basic share¹ of $0.01 and an unadjusted net loss of $107.5 million or loss per share of $0.60, derived from the sale of 48,843 gold equivalent ounces² ("GEO" or "GEOs"), which generated cash flow before changes in working capital of $27.2 million. For the full year 2019, the Company reports adjusted net income¹ of $13.0 million or adjusted earnings per basic share¹ of $0.07 and an unadjusted net loss of $93.1 million or loss per share of $0.52, derived from the sale of 194,269 GEOs, which generated cash flow from operations before working capital changes of $73.8 million. All dollar amounts are expressed in United States dollars unless otherwise specified.

CEO Commentary
Pete Dougherty, President and CEO stated: "During 2019, we increased our consolidated Mineral Reserves by 48%, GEO production by 13% and grew our net cash position by over $26 million. As we look to 2020, we are improving operations to reduce our unit costs by processing run-of-mine versus crushed ore at El Castillo, optimizing overburden haul cycle distances and modifying processing parameters. While this will lead to slightly lower GEO production in 2020, we expect it will also lead to higher profitability and stronger cash flow."

The Company has reported adjusted cash cost per gold ounce sold¹ and adjusted all-in sustaining cost per gold ounce sold ("AISC")¹, as it believes these are the most representative measures of the unit operating and sustaining costs on a per ounce sold basis for the three months and year ended December 31, 2019 given the write-downs taken on work-in-process mineral inventory during 2019. Adjusted cash cost per gold ounce sold¹ was $972 during the fourth quarter 2019 and $923 during 2019 and, with the write-down of work-in-process mineral inventory, cash cost per gold ounce sold¹ was $1,441 during the fourth quarter of 2019 and $1,041 during 2019. Adjusted AISC¹ was $1,221 during the fourth quarter of 2019 and $1,181 during 2019 and, with the write-down of work-in-process mineral inventory, AISC¹ was $1,690 during the fourth quarter of 2019 and $1,299 during 2019. Key operating and financial statistics for the three months and year ended December 31, 2019 are outlined in the following table:

Financial Results – Fourth Quarter 2019
Revenue for the three months ended December 31, 2019 was $72.1 million, an increase from $51.6 million for the three months ended December 31, 2018. During the fourth quarter of 2019, gold ounces sold totaled 47,073 at an average realized price per ounce of $1,484 (compared to 41,030 gold ounces sold at an average price per ounce of $1,226 during the same period of 2018).

Production costs for the fourth quarter of 2019 were $48.0 million, an increase from $38.0 million in the fourth quarter of 2018, primarily due to the increase in gold ounces sold and a slight increase in adjusted cash cost per gold ounce sold (see "Non-IFRS Measures" section). Adjusted cash cost per gold ounce sold (see "Non-IFRS Measures" section) for the fourth quarter of 2019 was $972, comparable to $945 in the same period of 2018. Depreciation, depletion and amortization ("DD&A") expense included in cost of sales for the fourth quarter of 2019 totaled $12.7 million, an increase from $8.6 million in the fourth quarter of 2018, primarily due to the increase in cost per ounce at the La Colorada mine, and the increase in gold ounces sold, as many of the mining assets are amortized on a unit-of-production basis. Included in the cost of sales in the fourth quarter of 2019 is an impairment write down of work-in-process inventory, which is discussed below.

General and administrative expenses for the fourth quarter of 2019 were $3.3 million, comparable to $3.4 million in the same period of 2018.

Other operating income for the fourth quarter of 2019 was $2.4 million, an increase from other operating expense of $3.1 million in the fourth quarter of 2018, primarily due to the revision of estimated reclamation costs associated with a section of the La Colorada mine where mining activities have ceased.

Losses on derivatives for the fourth quarter of 2019 were $2.4 million, compared to gains of $0.5 million in the fourth quarter of 2018, primarily due to unrealized losses on the Company's outstanding zero-cost collar commodity contracts.

Other income for the fourth quarter of 2019 was $2.7 million, an increase from other expense of $0.8 million in the fourth quarter of 2018, primarily due to proceeds from the disposal of mineral properties, plant and equipment in the fourth quarter of 2019 and differences in foreign currency translation effects.

There were two significant impairment write downs during the fourth quarter of 2019: first, a write down of mineral inventory at the El Castillo Complex ($20.1 million) and La Colorada mine ($12.1 million) primarily related to changes in the expected recovery of gold ounces in the leach pads and second, a non-cash write down of the book value of the San Antonio project ($111.0 million) following the denial of the permit application. The associated tax impact of these, along with other results from operations, was an income tax recovery of $25.8 million compared to $1.3 million in the same period of 2018.

Adjusted net income for the fourth quarter of 2019 was $2.7 million or $0.01 per basic share, comparable to $2.5 million or $0.01 per basic share for the fourth quarter of 2018 (see "Non-IFRS Measures" section). Unadjusted net loss was $107.5 million or $0.60 per share for the fourth quarter of 2019.

Financial Results – 2019
Revenue for 2019 was $268.9 million, an increase from $196.1 million for 2018. Gold ounces sold totaled 187,802 at an average realized price per ounce of $1,390 (compared to 149,695 gold ounces sold at an average price per ounce of $1,267 for 2018). Gold ounces sold for 2019 increased compared to the same period in 2018 primarily due to an increase in production at the El Castillo and La Colorada mines as a result of increases in grade and lower ounces in ending inventory that were produced but not sold at the El Castillo Complex.

Production costs for 2019 were $181.0 million, an increase from $122.9 million in 2018, primarily due to the increase in gold ounces sold and an increase in cash cost per gold ounce sold. Adjusted cash cost per gold ounce sold (see "Non-IFRS Measures" section) for 2019 was $923, an increase from $792 in the same period of 2018, primarily due to an increase in adjusted cash cost per gold ounce sold at the San Agustin mine due to a higher waste to ore ratio and lower gold grades. DD&A expense included in cost of sales for 2019 totaled $45.9 million, an increase from $33.2 million for 2018, primarily due to the increase in gold ounces sold, as many of the mining assets are amortized on a unit-of-production basis. Included in the cost of sales in 2019 is an impairment write down of work-in-process inventory, which is discussed below.

General and administrative expenses for 2019 were $13.8 million, an increase from $13.0 million for 2018, primarily due to employee related costs.

Other operating income for 2019 was $2.4 million, an increase from other operating expense of $3.1 million for 2018, primarily due to the revision of estimated reclamation costs associated with a section of the La Colorada mine where mining activities have ceased.

Losses on derivatives during 2019 were $1.4 million, compared to gains of $1.1 million for 2018, primarily due to unrealized losses on the Company's outstanding zero-cost collar commodity contracts in 2019.

Other income for 2019 was $3.5 million compared to other expense of $0.7 million in 2018, primarily due to proceeds from the disposal of mineral properties, plant and equipment, proceeds related to a bankruptcy filing and differences in foreign currency translation effects in 2019.

There were two significant impairment write downs in 2019: first, a write down of mineral inventory at the El Castillo Complex ($15.4 million) and La Colorada mine ($12.1 million) primarily related to changes in the expected recovery of gold ounces in the leach pads and second, a non-cash write down of the book value of the San Antonio project ($111.0 million) following the denial of the permit application. The associated tax impact of these, along with other results from operations, was an income tax recovery of $15.4 million compared to income tax expense of $6.7 million in the same period of 2018.

Adjusted net income for 2019 was $13.0 million or $0.07 per basic share compared to $16.4 million or $0.09 per basic share in 2018 (see "Non-IFRS Measures" section). Unadjusted net loss for 2019 was $93.1 million or $0.52 per share.

Operational Results – Fourth Quarter and Full Year 2019
During the fourth quarter of 2019, the Company achieved production of 47,521 GEOs at an adjusted cash cost per gold ounce sold of $972 and an adjusted all-in sustaining cost ("AISC") per gold ounce sold of $1,221, compared to 51,658 GEOs at an adjusted cash cost of $945 per gold ounce sold and an adjusted AISC per gold ounce sold of $1,073 during the fourth quarter of 2018 (see "Non-IFRS Measures" section). Higher adjusted AISC per gold ounce sold was primarily due to higher deferred stripping, leach pad construction and crushing, conveying and mining equipment costs.

In November 2019, the Company guided to 2019 production of between 190,000 and 200,000 GEOs. During 2019, the Company achieved annual production of 186,615 GEOs at an adjusted cash cost per gold ounce sold of $923 and an adjusted AISC per gold ounce sold of $1,181, compared to 165,117 GEOs at an adjusted cash cost of $792 per gold ounce sold and an adjusted AISC per gold ounce sold of $969 during 2018 (see "Non-IFRS Measures" section). Lower than anticipated production was primarily due to water in the pits at the El Castillo and La Colorada mines, which led to slower mining rates and suboptimal crushing throughput rates due to a lack of ore coming from the mines, and lower than anticipated recoveries at the La Colorada mine. Higher adjusted cash cost per gold ounce sold was primarily due to an increase in adjusted cash cost per gold ounce sold at the San Agustin mine due to a higher waste to ore ratio and lower gold grades. Higher adjusted AISC per gold ounce sold is primarily related to higher deferred stripping and crushing, conveying and mining equipment costs.

Pete Dougherty commented: "We experienced challenges in delivering ore to the crushers at both El Castillo and La Colorada during the quarter due to water in the pits. The lack of ore feed for the crushers led to suboptimal crusher utilization and fewer tonnes to the leach pads. We have improved our pit de-watering practices and have experienced a significant improvement so far in 2020. We took a write-down to our mineral inventory in the fourth quarter of 2019. At El Castillo, we had previously drilled an old heap to determine the ounces still in the heap and made recovery assumptions on these ounces. After initiating a re-leach program in 2019, we now have a better understanding of the amount of ounces we will ultimately recover from this heap and made the appropriate adjustment to mineral inventory. At La Colorada, the height of the lifts on the leach pads led to channeling and trapped ounces. We've reduced our lift height at all mines. A key focus of the entire organization in 2020 is lowering the unit cost per tonne processed and maximizing profitability and cash flow."

FOURTH QUARTER AND FULL YEAR 2019 EL CASTILLO COMPLEX OPERATING STATISTICS

Summary of Production Results at the El Castillo Complex
During the fourth quarter of 2019, the El Castillo Complex produced 8% fewer GEOs than during the fourth quarter of 2018, due to a 27% decrease in GEO production at the El Castillo mine partially offset by an 11% increase in GEO production from the San Agustin mine. At El Castillo, ore tonnes mined were impacted by water in the pit, which led to slower mining rates and suboptimal crusher throughput rates due to a lack of ore coming from the mine. At San Agustin, ore tonnes mined increased by 20% compared to the fourth quarter of 2018, due to an increased mining rate to meet the increased crusher throughput capacity following an expansion of the San Agustin crushing and stacking system in the first half of 2019. This led to higher San Agustin GEO production compared to the fourth quarter of 2018.

During 2019, the El Castillo Complex produced 12% more GEOs than 2018, due to higher GEO production at the El Castillo mine partially offset by a 6% decrease in GEO production at the San Agustin mine. Higher 2019 GEO production at El Castillo compared to 2018 was primarily driven by drawing down ounces placed on the pad late in 2018 and placing ounces nearer to pad liners. Lower 2019 GEO production at San Agustin was primarily driven by the stretch of time in the second and third quarters where there was a lack of sufficient water to optimize solution flow rates. This issue was resolved by the end of the third quarter of 2019 and the Company expects higher production from San Agustin in 2020.

FOURTH QUARTER AND FULL YEAR 2019 LA COLORADA OPERATING STATISTICS

Summary of Production Results at La Colorada
During the fourth quarter of 2019, the La Colorada mine produced 8% fewer GEOs than during the fourth quarter of 2018, primarily due to water in the pit, which led to slower mining rates and suboptimal crushing throughput rates due to a lack of ore coming from the mine. Changes have been made to the pit de-watering practices, which have largely resolved this issue.

During 2019, the La Colorada mine produced 15% more GEOs compared to 2018. Higher production was primarily driven by a 28% increase in gold grade.

2019 Capital
Total capital spending for 2019 was $51.8 million, which was near the low end of the guidance range of between $50 million and $55 million, with $40.8 million spent at the Company's operating mines and $11.0 million spent on its development projects, exploration and other.

2020 Guidance and Plans
The Company anticipates it will produce between 175,000 and 185,000 GEOs during 2020 at a cash cost of between $900 and $1,000 per gold ounce sold and AISC of between $1,150 and $1,250 per gold ounce sold (see "Non-IFRS Measures" section).

2020 GEO Production and Cost Guidance

El Castillo Mine
For the El Castillo mine, the Company evaluated the costs associated with hauling ore to the crushers and running the crushers, assuming metallurgical recoveries for various ore types, versus leaching run-of-mine ore with a lower metallurgical recovery. Based on the results of this analysis, management determined that ceasing to operate the crushers and switching to leaching run-of-mine ore resulted in a higher profitability for the 2020 mine plan. Consequently, the Company has recently reduced its workforce at El Castillo by 103 employees and 100 contractors, idled its crushers and switched to a run-of-mine operation.

During 2020, the Company expects quarterly production at El Castillo to range from approximately 10,000 GEOs to 12,000 GEOs. The 2020 mine plan projects the mining and processing of the following ore types:

• 61% oxide ore;
• 2% transitional ore; and
• 37% sulphide ore.

An overall recovery of 35% is anticipated from run-of-mine leaching.

By eliminating crushing, the 2020 mine plan is expected to yield a unit cost savings of more than $2.00 per tonne processed compared to 2019 actual unit costs of $7.54 per tonne processed. The majority of these cost savings are in the areas of crushing and conveying and processing.

San Agustin Mine
Following a review of operations to maximize profitability from the 2020 mine plan for the San Agustin mine, the Company is estimating a crusher throughput rate of 27,000 tonnes per day and an additional 3,000 tonnes per day of run-of-mine material.

During 2020, the Company expects quarterly production to range from approximately 16,000 GEOs to 19,000 GEOs with production slightly weighted towards the first half of the year (50% to 55%) compared to the second half of the year (45% to 50%).

The 2020 San Agustin mine plan is expected to yield a unit cost savings of more than $1.00 per tonne processed compared to 2019 actual unit costs of $6.90 per tonne processed.

La Colorada Mine
Following a review of operations to maximize profitability from the 2020 mine plan for the La Colorada mine, the Company will alter ore beneficiation from three-stage crushing to two-stage crushing for certain ore from Phase Two of the El Creston pit due to the softness of the ore. Approximately 12% of the ore tonnes in the 2020 mine plan will require two-stage crushing and 78% will require three-stage crushing. The Company is estimating a crusher throughput rate of approximately 13,000 tonnes per day compared to a crushing throughput rate of approximately 12,300 tonnes per day during 2019.

During 2020, the La Colorada mine is expected to have the highest variability of quarterly production ranging from approximately 12,000 GEOs to 18,000 GEOs with production weighted to the second half of the year (55% to 60%), particularly the fourth quarter of 2020 (30% to 35%).

The 2020 mine plan is expected to yield a unit cost increase of approximately $0.60 per tonne processed compared to 2019 actual unit costs of $11.31 per tonne processed, primarily due to higher mining costs.

2020 Capital
The Company plans to invest between $40 million and $50 million in capital expenditures during 2020 with approximately 60% to 65% of the capital spend expected during the first half of 2020.

Non-IFRS Measures
The Company has included certain non-IFRS measures including "Cash cost per gold ounce sold", "Adjusted cash cost per gold ounce sold", "All-in sustaining cost per gold ounce sold", "Adjusted 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. 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.
