Lindero Mine, Argentina: Record quarterly gold production of 36,072 ounces of gold, 37% over the previous quarter, and a total of 104,161 ounces for the year, in line with guidance

During the fourth quarter, the operation screened 60 positive cases of COVID-19 onsite, with no disruptions to the operations. Travel restrictions to the country were lifted in November which led to an improvement in lead times and onsite technical assistance from foreign vendors.

In the fourth quarter of 2021, a total of 1.46 million tonnes of ore were placed on the leach pad, averaging 1.04 g/t gold containing an estimated 48,900 ounces of gold. Total gold production for the fourth quarter was 36,072 ounces.

Gold production for 2021 totaled 104,161 ounces, comprised of 99,313 ounces in dor?, 730 ounces of gold contained in precipitate/sludge and 4,118 ounces of gold-in-carbon (GIC) inventory, in the upper range of the production guidance (refer to Fortuna news release dated July 19, 2021).

2021 Operating Highlights

Mine production for the quarter performed according to management's expectations. A total of 2,601,678 tonnes of ore were mined in the fourth quarter, at a strip ratio of 0.77:1. Total mine production for the year accounted for 8,493,508 tonnes of ore, at a strip ratio of 0.82:1, in line with plan.

All processing areas performed according to plan:

• A total of 1,444,260 tonnes of ore were crushed and placed on the leach pad via conveyor stacking during the fourth quarter, a 17 percent increase over the previous quarter
• Conveyor stacking performance averaged 16,228 tonnes per day during the fourth quarter, an increase of 21 percent over the previous quarter; including 31 days of conveyor stacking throughput of over 18,750 tonnes per day
• SART plant reached full design capacity of 393 cubic meters per hour in December 2021, in line with plan
• The expansion of carbon columns at the ADR plant was successfully commissioned in the fourth quarter of 2021 and is performing according to plan

Reconciliation of tonnes, head grade and gold ounces mined as ore demonstrated a good correlation with the reserve model throughout 2021, with differences for all parameters of less than 6 percent for the year.

The metallurgical balance indicates that overall actual gold recovery from the heap is performing in line with expected theoretical recoveries, supported by ongoing 2.5-meter-tall column test works and is according to the granulometric composition and metallurgical types of ore placed on the leach pad to date.

Notes:
1. Lindero tonnes and gold grade are estimated using grade control sampling of blast holes; tonnes are reported to the nearest thousand
2. Quarter-on-quarter change in GIC inventory

Quality Assurance & Quality Control

Grade control estimates at Lindero are based on blast hole chip samples submitted to Lindero's on-site laboratory for preparation and assaying for gold, using fire assay with an atomic absorption finish. The QA-QC program includes the blind insertion of certified reference standards and assay blanks at a frequency of approximately 1 per 20 normal samples as well as the submission of duplicate samples for verification of sampling and assay precision levels by an ISO 9001:2000 certified umpire laboratory. ALS Global Laboratory in Mendoza, Argentina prepared the samples for assaying and then forwarded the samples to ALS Global Laboratory in Lima, Peru for assay by standard fire assay methods.

San Jose Mine, Mexico: Solid production performance and stronger fourth quarter in line with full-year production guidance

The San Jose Mine produced 1,717,533 ounces of silver and 9,929 ounces of gold in the fourth quarter of 2021, with average head grades for silver and gold of 219 g/t and 1.27 g/t, respectively.

Silver and gold production for 2021 totaled 6,425,029 ounces of silver and 39,406 ounces of gold, respectively. Average head grades for silver and gold for the year were 209 g/t and 1.29 g/t, respectively.

Yaramoko Mine, Burkina Faso: Second semester production slightly below guidance due to grade delay in the fourth quarter

The Yaramoko Mine produced 28,787 ounces of gold in the fourth quarter of 2021 with an average gold head grade of 6.99 g/t.

Gold production for the second semester of 2021 totaled 57,538 ounces of gold with an average gold head grade of 7.13 g/t; 7 percent below guidance for the period. This production shortfall was due to lower than planned mill feed grade in the fourth quarter of 2021, caused by the delay in mining several high-grade stopes and some localized grade variability at the 55 Zone. The unmined stopes will be resequenced into the mine plan in the first quarter of 2022.

Caylloma Mine, Peru: Outperformer producing 6,086 ounces of by-product gold, a 22% increase over upper production guidance range

Silver production in the fourth quarter of 2021 was 262,710 ounces with an average silver head grade of 73 g/t. Full 2021-year production totaled 1,073,672 ounces, an increase of 11 percent over 2020, with an average head grade of 76 g/t.

Gold production was 1,374 ounces in the fourth quarter with average gold head grade of 0.44 g/t. Gold production for 2021 totaled 6,086 ounces, an increase of 48 percent over 2020, with an average head grade of 0.49 g/t.

Lead and zinc production for the fourth quarter of 2021 was 8,419,454 pounds and 11,380,262 pounds with average head grades for lead and zinc of 3.20% and 4.25%, respectively. Base metal production for the full year of 2021 totaled 47,549,301 pounds of zinc, an increase of 4 percent over 2020, and 32,989,973 pounds of lead, an increase of 11 percent over 2020. Average head grades for lead and zinc for the year were 3.16% and 4.56%, respectively.

Cautionary Note to United States Investors Concerning Estimates of Reserves and Resources

Reserve and resource estimates included in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for public disclosure by a Canadian company of scientific and technical information concerning mineral projects. Unless otherwise indicated, all mineral reserve and mineral resource estimates contained in the technical disclosure have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards on Mineral Resources and Reserves.

Canadian standards, including NI 43-101, differ significantly from the requirements of the Securities and Exchange Commission, and mineral reserve and resource information included in this news release may not be comparable to similar information disclosed by U.S. companies.

Non-IFRS Financial Measures

This news release also refers to non-IFRS financial measures, including cash costs and all-in sustaining costs. These measures are not standardized financial measures under International Financial Reporting Standards (IFRS), the financial reporting framework used to prepare the financial statements of the Company, and therefore may not be comparable to similar financial measures disclosed by other mining companies. These Non-IFRS Measures include:

Cash Costs. The Company's method of calculating cash costs may differ from the measures used by other companies with similar descriptions. Investors are cautioned that Cash Costs should not be construed as an alternative to production costs, depreciation and amortization, and royalties determined in accordance with IFRS as an indicator of performance. The most comparable financial measure to cash costs is cost of sales.

All-in Sustaining Costs. The Company has adopted an AISC performance measure; however this performance measure does not have a standardized meaning. The Company conforms its AISC to that set out in the guidance issued by the World Gold Council. Although the WGC has published a standardized definition, companies may calculate these measures differently. All-in sustaining cash cost includes total production cash costs incurred at the Company's mining operations. Sustaining capital expenditures, corporate selling, general and administrative expenses, and brownfield exploration expenditures are added to the cash cost to calculate the all-in-sustaining cost. The Company believes that this measure represents the total costs of selling gold and silver from operations and provides the Company and its stakeholders with additional information on the Company's operational performance and the ability to generate cash flows. Certain cash expenditures such as new project spending, tax payments, dividends, and financing costs are not included. AISC also excludes government mining royalty recognized as income tax within the scope of IAS-12. The most comparable financial measure to AISC is a combination of financial measures which include: cost of sales, capital expenditures, general and administrative expenses and royalties.

Readers should refer to the "Non-IFRS Financial Measures" section in the Company's MD&A for the three and nine months ended September 30, 2021 dated November 10, 2021, which section is incorporated herein by reference, for an explanation of these measures and reconciliations to the Company's reported financial results in accordance with IFRS.
