Year-over-year lost time injury frequency rate (“LTIFR”) reduction of 7%. Received nationally awarded Environmental Socially Responsible Company recognition for the 10th consecutive year for its Mexican operations. At Magino, we continued to discover high-grade gold mineralization in six distinct zones below and adjacent to the planned pit: Elbow, Central, Scotland, #42, Sandy and South. We also filed an updated Technical Report in March 2022. At La Colorada, we discovered high-grade gold mineralization below the El Crestón pit. At San Agustin, we declared an initial sulphide inferred Mineral Resource, which has the potential to extend the mine life by six to ten years with further drilling and metallurgical work. At Florida Canyon, we received the air quality permit modification and installed new a conveying and stacking system. All dollar amounts are expressed in US$ US dollars unless otherwise stated. C$ reflects Canadian dollars. 1 GEOs are based on a conversion ratio of 85:1 for silver to gold for 2021 and 80:1 for 2020.

The Argonaut Gold Inc. (“Argonaut”) 2021 year was marked by significant accomplishments and major disappointments. Early in 2021, we kicked off construction of our Magino project in Ontario, Canada, which is our flagship asset. Magino’s importance to Argonaut cannot be overstated: it is planned to provide a much lower cost, longer life mine to our operating portfolio and will see the majority of our production and cash flow come out of the tier one jurisdiction of Ontario, Canada. To put this in perspective, our four current operating mines each averaged approximately 58,000/oz of gold production in 2021. Magino is expected to average 142,000 oz/year on its own over its first five years following its ramp up period. Our consolidated all-in sustaining cost (“AISC”) from our existing operations in 2021 are much higher than the Magino expected AISC as reported in a recently updated technical report. Simply put, Magino will transform Argonaut into a lower-cost, intermediate gold producer with 100% of Argonaut’s production coming from North America. We did, however, experience meaningful challenges during the first half of Magino’s construction, which led to a significant capital overrun for the project. We, as a Board, take responsibility and took swift action to institute a leadership change and we have been working tirelessly with management to put Argonaut on a solid financial footing to complete the construction of this important project. While Magino’s capital overrun was clearly a disappointment and not one that we took lightly, as evidenced by our actions, we did accomplish some significant milestones in 2021: 4 A MESSAGE FROM OUR LEADERSHIP Groundbreaking Ceremony at Magino in Dubreuiville, Ontario Canada • Record annual production of 244,156 gold equivalent ounces. • Record annual revenue of $437 million. • Record annual cash flow of $125 million. • Meaningful exploration results at Magino, La Colorada and Florida Canyon, as well as a 400% increase in mineral tenure at San Agustin, that all point to potential mine life extension opportunities. As we look forward to the next year, our primary focus is the execution of the Magino project. We believe that the biggest value drivers for Argonaut over the next several years are focused on the success of Magino through 1) the delivery of the project on schedule and within our updated capital budget outlined in December 2021, 2) a safe and efficient ramp up to name plate capacity following construction, and 3) a potential expansion to the processing facilities and the development of a high-grade underground mine that would operate concurrent with the open pit mine. We believe we have the right leadership in place with Larry Radford’s appointment as President and Chief Executive Officer, to lead our management team and execute on these key value drivers. We also want to recognize our existing management team for stepping up during the period of transition to help put Argonaut in the best position to succeed. While there is no doubt that we stumbled in 2021, the entire Argonaut team is working hard to ensure we are well-positioned to execute on our strategy of transitioning Argonaut from a higher-cost, junior producer with relatively short mine lives to a much lower-cost, intermediate producer with significantly longer mine lives. Argonaut needs to do better for its stakeholders. We look forward to the next year and beyond. Sincerely, James E. Kofman, Chairman 5 Argonaut Gold Inc. 2021 Annual & Sustainability Report EXECUTING OUR STRATEGY In 2021, we continued to execute our transformation strategy, transitioning our Company from a high-cost, junior producer with short mine lives to a lower-cost, intermediate producer with much longer mine lives. We executed on all three phases of our strategy to lay the foundation and set up the building blocks for the Company’s transformation. HARVEST REPLACE GROWTH RECORD ANNUAL CASH FLOW OF $125M EXPLORATION SUCCESS MAGINO CONSTRUCTION • Harvest cash from existing • Replace depleted gold • Growth through the development operations. ounces through exploration at existing assets. project pipeline. • All development stage assets provide much longer mine life and significantly lower operating costs. CONTINUED OPTIMIZATION “We are very encouraged with the possibility of significantly extending San Agustin’s mine life through potential exploration success in the recently acquired mineral concessions and the potential to process sulphide mineralized material. At La Colorada, the mine life currently runs through 2027. While we see good potential to extend this further, particularly at depth, we are currently focused on optimizing the existing LOM plan by accelerating waste stripping and/or eliminating certain waste stripping by transitioning to underground mining sooner on the El Crestón deposit. This LOM optimization work will be a major focus of the La Colorada team this year.” - Lowe Billingsley, Chief Operating Officer 6 TRANSFORMATION STRATEGY Pre-production drilling at Magino “Argonaut is generating positive cash flow through its existing operating portfolio, holds an enviable portfolio of growth assets and, once Magino comes on line next year, has the opportunity to transition from a higher cost, junior producer to a lower cost, intermediate producer with a more diversified jurisdictional profile.” Lowe Billingsley, Chief Operating Officer San Agustin Mine 7 Argonaut Gold Inc. 2021 Annual & Sustainability Report COMPANY SNAPSHOT MAGINO FLORIDA CANYON RENO HEAD OFFICE TORONTO OFFICE LA COLORADA EL CASTILLO COMPLEX CERRO DEL GALLO CONSOLIDATED MINERAL RESOURCES & RESERVES 2021 MEASURED & INDICATED MINERAL RESOURCES1,2 PROVEN & PROBABLE MINERAL RESERVES2 13.7Moz.

GEO production at the El Castillo mine was 6% higher and costs were 16% higher than 2020 due to an 11% increase in total tonnes mined, a 9% increase in ore tonnes loaded to the leach pads and higher recoveries, offset by a 28% reduction in gold grade. 2021 PRODUCTION 48,861 GEOs 2021 CASH COSTS1 per gold ounce sold $1,009 MEASURED & INDICATED MINERAL RESOURCES2 31.4Mt at 0.36 g/t Au 355k contained gold ounces PROVEN & PROBABLE MINERAL RESERVES3 11.3Mt at 0.39 g/t Au 142k contained gold ounces 1 Please refer to the “Notes and Disclosure” section for a discussion of these Non-IFRS Measures. 2 The Measured & Indicated Mineral Resources and Inferred Mineral Resources for El Castillo and San Agustin, which together form the El Castillo Complex, set out in the above table were based on pit cones using $1,800 per ounce gold and $24.00 per ounce silver. Cut-off grades range from 0.07 g/t Au to 0.48 g/t Au for El Castillo and 0.11 to 0.42 g/t Au for San Agustin, depending on ore type. 3 The Mineral Reserves for El Castillo and San Agustin, which together form the El Castillo Complex, set out in the above table are based on updated models, mine plans and topography, including depletion through mining activities and changes to recovery and cost assumptions as of October 1, 2021 for El Castillo and August 1, 2021 for San Agustin. El Castillo used a gold price of $1,650 per ounce; San Agustin used a gold price of $1,500 per ounce and silver price of $20.00 per ounce. Cut-off grades for El Castillo range from 0.10 g/t Au to 0.27 g/t Au depending on ore type; cut-off grades at San Agustin were 0.16 g/t AuEq except for material scheduled for mining in 2021 that used a cut-off grade of 0.13 g/t AuEq. 10 MATERIAL MINERAL ASSETS SAN AGUSTIN MINE El Castillo Complex - Durango, Mexico During 2021, GEO production at the San Agustin mine was 16% higher and costs were 17% higher than 2020 due to a 16% increase in total tonnes mined, a 19% increase in ore tonnes loaded to the leach pads and higher recoveries, offset by a 6% reduction in gold grade. In 2021 we acquired key mineral concessions for a cash consideration of US$5.75 million. The mineral concessions acquired more than quadruples Argonaut’s mineral tenure and area of potential exploration in the San Agustin district to 5,884 hectares. The acquired mineral concessions consist of a very large concession of 4,791 hectares surrounding all of Argonaut’s existing concessions in the district, as well as four key concessions totaling 27 hectares immediately surrounding the San Agustin pit. The acquisition of the four mineral concessions immediately adjacent to the San Agustin pit will allow Argonaut to expand the pit, increase mineral reserves and extend mine life. These strategic mineral concessions may also have potential to add mineralization to the northeast and southwest of the current mine footprint. The very large concession surrounding all of Argonaut’s existing mineral concessions in the San Agustin district increases Argonaut’s area of potential exploration by over 400%. Anomalous gold mineralization is known to occur in numerous areas of this concession, especially to the north and northwest of the current San Agustin mine operations. 11 2021 PRODUCTION 74,116 GEOs 2021 CASH COSTS1 per gold ounce sold $915 INDICATED MINERAL RESOURCES2 60.0Mt at 0.27 g/t Au and 7.6 g/t Ag 531k contained gold ounces and 14.8M contained silver ounces PROBABLE MINERAL RESERVES3 33.2Mt at 0.32 g/t Au and 9.1 g/t Ag 336k contained gold ounces and 9.7M contained silver ounces Significant increase in INFERRED MINERAL RESOURCE2 86.9Mt at 0.48 g/t Au and 14.7 g/t Ag 1.3M contained gold ounces and 41.0M contained silver ounces which includes 84.8Mt in initial sulphide Inferred Mineral Resource Argonaut Gold Inc. 2021 Annual & Sustainability Report LA COLORADA MINE Sonora, Mexico During 2021, the La Colorada mine produced 44% more GEOs at a cash cost per gold ounce sold1 22% lower than 2020. Higher GEO production was primarily due to a 47% increase in gold grade and a 34% reduction in strip ratio, partially offset by lower recoveries. In 2021, we initiated exploration programs at depth below the El Crestón pit exploring zones of high-grade gold and silver mineralization, with additional drilling is planned in 2022 to explore deeper for possible extension of the system. Drill highlights from 2021 include: News Release - April 26, 2021 • 20-LCRC-592 intersected 12.2m at 98.9 g/t Au and 30.3 g/t Ag, including 3.0m of 383.0 g/t Au and 113.5 g/t Ag • 20-LCRC-562 intersected 21.3m at 44.6 g/t Au and 274.9 g/t Ag, including 3.0 m of 283.1 g/t Au and 858.0 g/t Ag News Release – September 13, 2021 • South Vein: 21-LCRC-667 intersected 38.1m at 9.1 g/t Au and 126.6 g/t Ag, including 4.6 metres of 51.9 g/t Au and 28.5 g/t Ag • North Vein: 21-LCRC-657 intersected 29.0m at 3.62 g/t Au and 10.1 g/t Ag, including 4.6m of 17.4 g/t Au and 29.0 g/t Ag • Central Vein: 21-LCRC-673 intersected 22.9m at 6.7 g/t Au and 30.1 g/t Ag, including 1.5m of 90.0 g/t Au and 14.8 g/t Au 2021 PRODUCTION 66,964 GEOs 2021 CASH COSTS1 per gold ounce sold $730 INDICATED MINERAL RESOURCES2 36.1Mt at 0.62 g/t Au and 8.3 g/t Ag 714k contained gold ounces and 9.6M contained silver ounces PROBABLE MINERAL RESERVES3 21.1Mt at 0.67 g/t Au and 9.1 g/t Ag 456k contained gold ounces and 6.1M contained silver ounces 1 Please refer to the “Notes and Disclosure” section for a discussion of these Non-IFRS Measures. 2 The Indicated Mineral Resources and Inferred Mineral Resources for La Colorada set out in the above table were based on pit cones using $1,800 per ounce gold and $24.00 per ounce silver. Cut-off grade was 0.09 g/t AuEqto 0.11 g/t AuEq, depending on ore type. 3 The Mineral Reserves for La Colorada set out in the above table are based on updated models, mine plans and topography as well as updated recoveries and cost assumptions as of October 1, 2021. La Colorada used a gold price of $1,500 per ounce and a silver price of $20.00 per ounce. Cut-off grade for La Colorada was 0.13 g/t gold equivalent AuEq. 12 MATERIAL MINERAL ASSETS FLORIDA CANYON MINE Nevada, USA Argonaut acquired the Florida Canyon mine on July 1, 2020. During 2021, the first full year under Argonaut ownership, Florida Canyon production increased by 15.2% and cash cost increased by 5.9%. In 2021 we received 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. The receipt of the air quality permit modification allowed us to execute on our plan to lower cost and also raise the production profile at Florida Canyon. Furthermore, the conveying and stacking system will be operated on grid power and eliminate the need to run diesel haul trucks from the crusher to the leach pads, which we expect will reduce greenhouse gas emissions. We completed the construction and installation of the new conveying and stacking system, and ramped up to design capacity during the third quarter of 2021. This change also frees up mobile equipment to transport more ore tonnes from the open pit to the crusher and is expected to increase the annual production profile at Florida Canyon beginning in 2022. 2021 PRODUCTION 54,215 GEOs 2021 CASH COSTS1 per gold ounce sold $1,356 MEASURED & INDICATED MINERAL RESOURCES2 86.5Mt at 0.42 g/t Au 1.17Mt contained gold ounces PROVEN & PROBABLE MINERAL RESERVES3 68.4Mt at 0.42 g/t Au 921k contained gold ounces 1 Please refer to the “Notes and Disclosure” section for a discussion of these Non-IFRS Measures. 2 The Measured & Indicated Mineral Resources and Inferred Mineral Resources for Florida Canyon set out in the above table were based on pit cones using $1,800 per ounce gold.

Florida Canyon used a gold price of $1,500 per ounce. Cut-off grade for Florida Canyon was 0.17 g/t Au. 13 Argonaut Gold Inc. 2021 Annual & Sustainability Report MAGINO PROJECT Ontario, Canada In 2021, we continued to execute our growth strategy, advancing construction at Magino and targeting the first gold pour before the end of the first quarter in 2023. We’ve made significant progress on construction, building our team and collaborating with the community and indigenous groups, and have published a monthly newsletter to provide stakeholders with regular updates. We’ve also had continued success in our deep drilling exploration program, which specifically targets high-grade gold mineralization below and adjacent to the planned open pit. 2021 CONSTRUCTION MILESTONES INCLUDE: Logged project area; • Placed orders on long lead time components; • • Constructed camp facilities; • Made significant progress at process facility site; • Made significant progress at Tailings Management Facility; • Commenced open pit mining to generate waste rock; • Made significant progress at Water Quality Control Pond; • Commenced fish habitat work; and • Continued operational readiness preparation. CAPITAL UPDATE During 2021, Argonaut incurred $236.8 million in capital costs related to construction of the Magino project. 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. 1 Based on the assumptions and parameters as set forth in the Magino Feasibility Study dated February 14, 2022. 14 UPDATED FEASIBILITY STUDY HIGHLIGHTS1 MEASURED & INDICATED MINERAL RESOURCES 132.4Mt at 0.94 g/t Au 4.0M contained gold ounces PROVEN & PROBABLE MINERAL RESERVES 65.5Mt at 1.15 g/t Au 2.4M contained gold ounces 19 year mine life 142k ounces average annual gold production during the first 5 years following ramp up Average annual cash cost $888 per gold ounce sold Average annual AISC $963 per gold ounce sold ESTIMATED PROJECT CAPITAL AT COMPLETION C$800 million UNDERGROUND EXPLORATION SUCCESS In 2021, we continued our drilling campaign targeting high-grade gold mineralization at depth below the planned Magino open pit. We continued to discover high-grade gold mineralization in six distinct zones below and adjacent to the planned pit: Elbow, Central, Scotland, #42, Sandy and South. Drill highlights from 2021 include: MATERIAL MINERAL ASSETS News Release - January 20, 2021 • MA20-057 intersected 10.0m at 19.0 g/t Au, including 6.3m of 30.2 g/t Au • MA20-057 intersected 3.1m at 47.1 g/t Au, including 1.3m of 112.0 g/t Au News Release – July 8, 2021 • MA21-070 intersected 7.0m at 13.3 g/t Au • MA21-065 intersected 19.0m at 3.7 g/t Au News Release – November 16, 2021 • MA21-076 intersected 16.0m at 6.1 g/t Au. including 1.0m at 85.1 g/t Au Board visit to our Magino Core Shack Brian Arkell, Vice President of Exploration commented: “The early-stage resource definition drilling program continues to yield positive results with several high-grade gold intercepts at widths typically amenable to underground mining methods. I’m also very encouraged by the continuity of the gold mineralization we are seeing within the Elbow Zone, and we are excited to continue to test this important target.” FIRST NATIONS & MÉTIS COMMUNITY INVOLVEMENT Argonaut is frequently engaged with six indigenous communities and has Community Benefit Agreements with all six communities. To date, Argonaut has implemented four Environmental Committees during the past year and regularly meets with all communities to engage and share information on upcoming permitting and ongoing monitoring of the Magino Project. Recently, Argonaut Gold committed to in kind training for Missanabie Cree First Nation on the implementation of Bat Habitat Rehabilitation planning. The Bat Hibernaculum* being constructed by Argonaut Gold will provide unique opportunities to study and share bat hibernation ecology with the Missanabie Cree First Nation’s Land and Resources Department. Argonaut Gold also provided financial support to Missanabie Cree First Nation to support their own bat habitat rehabilitation initiatives.

Currently in the permitting phase, the project fits well within our Mexican team’s operating skill set as another open pit heap leach project. Cerro del Gallo, like Magino, is an asset that supports our transformation strategy from being a high-cost, short mine life junior producer to a lower-cost, long mine life intermediate producer. As we continue to advance permitting, we are also fostering our relationship with the local community. Our focus is providing project education to residents, establish long-standing relationships with key partners in the community including gaining municipal and state support. 1 Based on the assumptions and parameters of the Cerro del Gallo Pre-Feasibility Study results announced on December 18, 2019. 16 PRE FEASIBILITY STUDY HIGHLIGHTS1 MEASURED & INDICATED MINERAL RESOURCES 201.9Mt at 0.44 g/t Au, 12.2 g/t Ag and 0.09% Cu 2.86M contained gold ounces, 79.1M contained silver ounces, and 187.1T contained copper PROVEN & PROBABLE MINERAL RESERVES 91.8Mt at 0.56 g/t Au, 13.3 g/t Ag and 0.10% Cu 1.64M contained gold ounces, 39.1M contained silver ounces and 85.5T of contained copper 15 year mine life 77k ounces average annual gold production during the first 5 years following ramp up Average annual cash cost $597 per gold ounce sold Average annual AISC $667 per gold ounce sold INITIAL PROJECT CAPITAL $135M SUSTAINABILITY An overview of our commitment to socially responsible practices and sustainability initiatives in 2021 17 Argonaut Gold Inc. 2021 Annual & Sustainability Report 2021 ESG SNAPSHOT Our team excelled in safety at our operations and achieved: 10th 7% CONSECUTIVE YEAR RECEIVING ESR AWARD FOR MEXICAN OPERATIONS REDUCTION IN YEAR-OVER-YEAR LOST TIME INJURY FREQUENCY RATE (“LTIFR”) 1.5M HOURS WITHOUT DISABLING ACCIDENTS AT LA COLORADA By switching to solar panels to generate alternative energy and benefited by: 24% REDUCTION IN GHG EMISSIONS AT LA COLORADA 7% 2.2 tonnes REDUCTION IN WATER EVAPORATION RATE AT EL CASTILLO REDUCTION IN GHG EMISSIONS AT EL CASTILLO 18 SUSTAINABILITY CSR EXCELLENCE AND THE PATH TO ESG REPORTING Corporate social responsibility continues to be a critical aspect of our business.

Alfredo Phillips Greene Vice President, Corporate Affairs & Country Manager, Mexico 19 Argonaut Gold Inc. 2021 Annual & Sustainability Report OUR SAFETY Safety remains our number one priority, and in 2021 we demonstrated both excellence and leadership. We have achieved safety milestones including a 7% year-over-year LTIFR reduction, maintaining zero accidents for the entire year at El Castillo and exceeding 1.5 million hours without disabling accidents at La Colorada. We also prioritized health, continuing to manage and monitor the pandemic. Health workshops were also made available and included topics such as occupational health and mental health awareness. During the year, our operations teams completed over 21,300 combined hours of safety related training. 3 YEAR OPERATIONAL SAFETY STATS 2019 2020 2021 El Castillo Lost Time Accidents Total Reportable San Agustin Lost Time Accidents Total Reportable La Colorada Lost Time Accidents Total Reportable Florida Canyon1 Lost Time Accidents Total Reportable 1 21 3 24 5 32 1 18 0 13 3 30 0 21 1 19 1 25 3 10 Safety training at San Agustin 1 Argonaut took ownership of Florida Canyon on July 1, 2020. In 2021, we continued to provide internal training programs on risk prevention and safety protocols, with the goal of preserving the health and safety of all workers. Safety campaigns included: • San Agustin Safety Campaign resulted in the detection and correction of unsafe conditions. The implementation of our internal safety system through the “Supervisor Binder” program is another action based on safety related activities that Supervisors and workers are to carry out on a daily basis to improve their corresponding working areas. • Florida Canyon “The Care to Lead” safety culture workshops focused on transparent incident reporting. Employees responded by reporting 21% more safety events overall in 2021. The 21% increase in event reports was slightly higher than the 13% increase in headcount, which also led to the increase in overall safety events. Reportable injuries increased by 25% and property damages increased by 28%. Near miss reporting was the lone reduction in 2021, dropping 26% from 2020. 20 SUSTAINABILITY The team at El Castillo achieved zero accidents in each quarter of 2021. “Safety is one of the pillars we prioritize in our operation. We are proud that last year we exceeded 1.5 million work hours without disabling accidents.” Manuel Ernesto Encinas Cabrera, General Manager of the La Colorada Mine. MANAGING COVID-19 We continued to manage the pandemic through 2021 practicing company- wide prevention protocols, regular sanitization, regular testing, and monitoring. In addition to our protocols, we also continued our integral health program at Mexico operations for vulnerable workers, ensuring regular check-ups and medical assistance if needed. As we ramped up construction at Magino last year, we were diligent in practicing safety protocols when on-boarding an influx of new team members. Regular antigen and PCR tests were taken, totaling over 13,000 tests during the year. Over 80% of on-site employees and contractors are fully vaccinated, and we provided over 260 on-site nurse visits in the second half of 2021. Antigen testing at El Castillo. 21 Argonaut Gold Inc. 2021 Annual & Sustainability Report OUR PEOPLE As we work to transform Argonaut, we continued to invest in and grow our best asset - our human capital. We made significant additions to our team in 2021, as we ramped up hiring at Magino. We grew from 19 Magino employees to 141, and we are continuing to grow as we near our first gold pour in early 2023. We also made changes in our leadership team, welcoming Alfredo Phillips Greene as the Vice President, Corporate Affairs & Country Manager in Mexico and promoting Lowe Billingsley to Chief Operating Officer.

Educational support in 2021 included: • At La Colorada, we invested $455,400 MXN in a total of 443 scholarships and backpacks with school supplies to 100% of the students who live in the Community of La Colorado Sonora. • We also have an agreement with two universities to receive interns in our Unit. We also use these universities as a job bank for former students: State University of Sonora and Technological University of Hermosillo. • At El Castillo, we invested $1,620,322 MXN for a total of 758 bi-monthly scholarships that were distributed among students in the Otilio Montaño Community. We also offered the first local Summer Camp to children and youth in Otilio Montaño. • At San Agustin, we invested $3,954,184 MXN for a total of 2,078 bi- monthly scholarships that were distributed among students in the communities of San Agustin, San Lucas, Las Cruces and Mimbres. Grocery packages in lieu of in-school breakfast programs for students were also provided on a bi-weekly basis, totaling an investment of $117,428 MXN. We also offered the first local Summer Camp to children and youth in San Agustin and San Lucas. • At Florida Canyon, we participated in local school events such as the Senior Exit Interviews which assists in preparing graduating high school seniors with college admission or job interviews, and the Freshman Expo / 4th Grade Gold Rush exhibits which educates youth on careers in the mining industry. We also sponsored scholarships for the Maintenance Cooperative Training program, a local technical college training program which provides students with technical trades at Florida Canyon. • At Magino, we participated in the Algoma District School Board Trades Promo Night for students and parents of the Algoma District to discuss different career opportunities in the trades and the highlights of our industry. • At Cerro del Gallo, we donated over 300 school supply packages in partnership with the Ministry of Education, to various schools in Silleros, Los Avilés, Santa Bárbara, Las Lozas, La Colmena and San Isidro del Sisote, communities in the municipality of Dolores Hidalgo. 26 Student scholarships and school supply delivery in La Colorada, Mexico Summer Camp for children and youth in San Agustin and San Luca, Mexico High school students at the Freshman Expo in Winnemucca, Nevada SUSTAINABILITY Rehabilitation of community buildings in La Colorada Existing local equipment we provided maintenance for in San Juan del Río, Mexico Donation of materials to the communities of San Lucas, San Agustin, Mimbres and las Cruces Solar panels installed to provide power for water well pumps in the community of San Lucas, Mexico COMMUNITY INFRASTRUCTURE Investing in proper infrastructure is key to ensuring communities have the proper support to thrive. This includes roads, agricultural support, and support for local businesses. In 2021, we made key contributions including: • At La Colorada, we rehabilitated a total of 212 kilometres of neighborhood roads in the communities of Cobachi, La Galera and Estación Torres. Our goal of rehabilitating 100% of the houses in the La Colorada Community continues, and in 2021 a total of 32 houses have been rehabilitated, including the three educational centers in the municipality. • At El Castillo, we provided maintenance of approximately eight kilometres of a locally owned road, provided maintenance for equipment owned by the Municipal Administration of San Juan del Río for the municipal road works, and also donated a totem pole and pipe lines to Ejido Otilio Montaño. • At San Agustin, we provided road maintenance to approximately 44 kilometres in San Lucas, provided equipment to be installed at the Los Jacales well in Ejido San Agustin and installed solar panels to run the pump in the water well of the junior high school in the community of San Lucas. We also donated drinking water to the communities of San Lucas, San Agustin, Mimbres and las Cruces. Three cleaning campaigns were also conducted, where team members, contractors and community residents participated. This included a campaign on the state highway access to San Juan del Río, collecting approximately 2.7 tonnes of trash. • At Florida Canyon, we helped build new units for the local animal shelter, Safe Haven. • At Magino, we assisted the Community of Dubreuilville to create a gravel walking path for the local youth and citizen to walk to the beach instead of walking on the side of the road. We also graded the main road to go to the lodge and assisted with upkeep, and provided funding for speed bumps to assist with speed reduction of traffic coming into town to ensure pedestrian safety. • At Cerro del Gallo, we assisted in the rehabilitation of the local church roads, and also assisted in the rehabilitation of health buildings in the community of San Antón de las Minas. 27 Argonaut Gold Inc. 2021 Annual & Sustainability Report At El Castillo we migrated from a sprinkler irrigation system to an on-surface drip system for our leach pads. By switching we were able to optimize our water usage. OUR ENVIRONMENT Argonaut is committed to continuously optimizing our operations to reduce our use of natural resources and our impact on the environment as we continue to grow. In 2020 we began to implement changes, and in 2021 we continued to our optimizations that resulted in a reduction in water consumption, energy consumption and greenhouse gas emissions (“GHG”). Argonaut also prioritizes environmental monitoring programs that measure dust and continues to manage and meet standards in compliance with local regulatory requirements. MINIMIZING CONSUMPTION & OPTIMIZING OPERATIONS We began migrating from the sprinkler irrigation system to the on-surface drip hose system in early January 2020. Leaving sprinklers only on embankments, the migration represented significant water consumption savings and water optimization. In 2021, the migration from sprinkler irrigation to the dripping hose system achieved the following benefits: EL CASTILLO COMPLEX LA COLORADA 7% reduction in evaporation factor 5% reduction in evaporation factor OVERALL BENEFITS • • reduced wind drift losses • controlled irrigation rate reduced ponding from moisture saturation on surface • flow priority optimization on fresh ore 28 SUSTAINABILITY Installing solar panels at La Colorada allowed us to reduce our diesel consumption. “By installing solar panels in some areas of the mine, we reduce the emissions formerly generated by the processes where they were installed, as there is no need to use any more fuel and generators. Noise is also reduced, and all this brings economic benefits but above all, we generate a benefit for the environment.” Daniel Vazquez, Maintenance Superintendent at the El Castillo mine ALTERNATIVE ENERGY By installing solar panels for the new communication antenna and booth buildings at the El Castillo Complex and La Colorada, we were able to reduce diesel consumption and GHG emissions. We are also in the process of switching from diesel generator to the electric power grid at San Agustin. This change is currently underway, which will lower the cost to $0.09 - $0.11/kWhr from the current cost is $0.29/kWhr. In 2021, we were able to achieve the following by switching to alternative energy: EL CASTILLO COMPLEX LA COLORADA 4,519 kWh saved which is equivalent to 67% diesel reduction which is equivalent to 2.2 tonnes GHG 24% GHG reduction IN THE COMMUNITY Last year we donated and installed solar panels at the local high school to power the water well pump in San Agustin. Implementing this system contributes to a savings of approximately 4,500 litres of diesel used per year in the conventional system. We were able to reduce the GHG emissions by approximately 12 equivalent tonnes. 29 Argonaut Gold Inc. 2021 Annual & Sustainability Report ENVIRONMENTAL PROGRAMS AT MAGINO BAT HIBERNACULUM An existing mine adit at the Magino Project, in place from mining operations in the 1980s, provided bat hibernation habitat for the northern myotis and the little brown myotis bat. Both species have experienced substantial population declines throughout their northeastern North American range, in large part, due to mortality from White Nose Syndrome (WNS). WNS is an infectious disease caused by fungus which grows on the skin of infected bats during hibernation. Little brown myotis and northern myotis are designated as endangered under the Endangered Species Act, 2007 (ESA). Prior to removal of this habitat, an overall benefit permit, issued by the Ministry of Environment, Conservation and Parks is required. For the overall benefit to be achieved, a new hibernaculum needs to be constructed. In addition, Bat Habitat Rehabilitation and Artificial Bat Roosting Plans will also be developed. The new bat hibernaculum is scheduled to be constructed in the second quarter of 2022. Drafts for the Bat Habitat Rehabilitation and Artificial Roosting Plans are underway with drafts to be completed by June 2022. The draft plans will be shared with all indigenous communities partnered in the project, and the indigenous knowledge gained from the communities will be incorporated into the plans prior to being submitted to the Regulatory Agency. FISH HABITAT To facilitate development of the Magino Project, there will be a need to overprint or otherwise impact waterbodies (lakes, streams and wetlands) that contain fish and/or provide fish habitat. As a result, the provision of compensatory offsetting measures to replace the impacted fisheries values associated with the water features will be necessary. The following measures are being implemented to provide compensation for the impacts and offsets to the effected fish habitat. A new diversion channel between the Spring Lake outlet and McVeigh Creek Southwest is planned to be constructed. The next measure will be to create new habitat south of Webb Lake. The constructed lake basin(s) will be designed to provide in-kind habitat replacement consistent with the majority of the habitat impacted by the project. Whereas the majority of impacted waterbodies are baitfish or low diversity sportfish communities, new basins will largely target supporting a high diversity fish community consistent with community interests and the MNRF provincial fisheries objective for this area. The third measure is to re-introduce fish in previously industrial impacted areas. The fish community restoration offsetting measure will reintroduce Consultants working on fish relocation program at Magino top-level predators (i.e. Brook Trout and/or Lake Trout) into the previously impacted lakes. Predatory fish were historically present in these lakes but were extirpated due to the temporary water quality degradation from the severe acid deposition. Trout species are unlikely to colonize naturally without intervention due to the lack of exiting trout populations in the upper watershed, and the small size of the aquatic systems connecting the lakes to downstream populations. The fish habitat construction is underway. The reintroduction of fish into historically impacted areas is also scheduled to begin in the second quarter of 2022. 30 SUSTAINABILITY SPECIES AND PLANT RESCUE CAMPAIGNS AT OPERATIONS NATIONAL FORESTRY FUND DONATION: MXN $6,247,616 Donated by La Colorada • La Colorada: Nearly 31 hectares were reforested in 2021. To date 62.27 hectares have been rescued, 600 meters of plant lines were laid, 77 filter dams and 6,416 plants were rescued. In 2021, the total wildlife that were rescued included 4 turtles, 5 vipers, 2 chameleons and 1 eagle found within the property. • El Castillo: Rescued and relocated flora including a total of 31 individual cactus species. We also rescued and relocated a total of seven rattlesnakes found within the property. • San Agustin: Rescued and relocated flora including a total of 118 individuals cactus species. The nursery has a current inventory of 7000 individuals of huizaches, mezquites and yuca species. Flora species part of the San Agustin rescue and relocation program “Our main goal for the El Castillo’s Restoration and Closure Plan is using the best strategies to sustain the natural resources used in our reforestation activities so they can be incorporated into the environment in a harmonious fashion. Establishing a reforestation program which reincorporates rescued flora, as well as plants reproduced with the site’s germoplasma, will enable us to reach higher survival percentages due to a better adaptability to the site conditions, like weather, topography, elevation and sun exposure. Vegetation rescue programs, as well as reproduction are fundamental for the success of the Restoration and Closure Plan.” Guillermo Velasco, Closure Plan Superintendent at the El Castillo mine 31 On-site plant nursery at San Agustin in Durango, Mexico. 32 GOVERNANCE & LEADERSHIP ARGONAUT’S MANAGEMENT An overview of Argonaut’s Risk Management, Governance and Leadership. 33 Argonaut Gold Inc. 2021 Annual & Sustainability Report MANAGING RISKS Argonaut’s approach to risk management is based on an outline that incorporates risk awareness across our entire Company, where we are able to identify, assess, prioritize and manage these risks systematically.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS This report contains certain “forward-looking statements” and “forward-looking information” under applicable Canadian securities laws concerning the business, operations and financial performance and condition of Argonaut Gold. Forward-looking statements and forward-looking information include, but are not limited to statements with respect to: the Magino construction capital estimate; the ability to finance additional construction costs on terms acceptable to Argonaut; the realization of mineral reserve estimates; the timing and amount of estimated future production; the impact of inflation on costs of exploration, development and production; estimated production and mine life of the various mineral projects of Argonaut; timing of approval for modifications to existing permits; permitting and legal processes in relation to mining permitting and approval; the benefits of the development potential of the properties of Argonaut; the future price of gold, copper, and silver; the estimation of mineral reserves and resources; success of exploration activities; the impact of COVID-19, the response of governments to COVID-19 and the effectiveness of such responses; and currency exchange rate fluctuations. Except for statements of historical fact relating to Argonaut, certain information contained herein constitutes forward- looking statements. Forward-looking statements are frequently characterized by words such as “plan,” “expect,” “project,” “intend,” “believe,” “anticipate”, “estimate” and other similar words, or statements that certain events or conditions “may”, “should” or “will” occur. Forward-looking statements are based on the opinions and estimates of management at the date the statements are made and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of Argonaut and there is no assurance they will prove to be correct. 39 Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include the availability and changing terms of financing, variations in ore grade or recovery rates, changes in market conditions, changes in inflation, risks relating to the availability and timeliness of permitting and governmental approvals; risks relating to international operations, fluctuating metal prices and currency exchange rates, changes in project parameters, the possibility of project cost overruns or unanticipated costs and expenses, the impact of COVID-19 and the impact and effectiveness of governmental responses to COVID-19, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated. These factors are discussed in greater detail in Argonaut’s most recent Annual Information Form and in the most recent Management’s Discussion and Analysis filed on SEDAR, which also provide additional general assumptions in connection with these statements. Argonaut cautions that the foregoing list of important factors is not exhaustive. Investors and others who base themselves on forward-looking statements should carefully consider the above factors as well as the uncertainties they represent and the risk they entail. Argonaut believes that the expectations reflected in those forward-looking statements are reasonable, but no assurance can be given that these expectations will prove to be correct and such forward-looking statements included in this press release should not be unduly relied upon. These statements speak only as of the date of this press release. Although Argonaut has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward- looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward- looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Argonaut undertakes no obligation to update forward-looking statements if circumstances or management’s estimates or opinions should change except as required by applicable securities laws. The reader is cautioned not to place undue reliance on forward-looking statements. Statements concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking statements to the extent they involve estimates of the mineralization that will be encountered if the property is developed. Comparative market information is as of a date prior to the date of this document. NON-IFRS MEASURES The Company has included certain non-IFRS measures including “Cash cost per gold ounce sold” and “All-in sustaining cost per gold ounce sold” in this report 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. 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 ac-cordance with IFRS. Please see under the heading “Non-IFRS Measures” in the management’s discussion and analysis (“MD&A”) for full disclosure on non-IFRS measures. The disclosure under the heading “Non-IFRS Measures” in the MD&A is incorporated by reference herein. The MD&A is available under the Company’s profile at www.sedar.com. This report should be read in conjunction with the Company’s audited annual consolidated financial statements for the year ended December 31, 2021 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. 40 W W W .
