Fortuna Reports Third Quarter 2021 Unaudited Financial Results

VANCOUVER, Nov. 11, 2021 - Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) ("Fortuna" or the "Company") today reported third quarter 2021 net income of $0.2 million, adjusted net income¹ of $22.5 million, and adjusted EBITDA¹ of $75.3 million.

Jorge A. Ganoza, President and CEO, commented, "Our strong adjusted EBITDA¹ of $75.3 million with margins of 46% and free cash flow from operations¹ of $33.8 million in the third quarter attest to the strength of our business. Our record financial results reflect the sustained upward production trend at the Lindero mine in Argentina and the first quarterly contribution of the Yaramoko mine in Burkina Faso." Mr. Ganoza concluded, "We expect our robust cash flow generation to continue to be our main source of funding as we ramp up construction activities at the Seguela project in Côte d´Ivoire."

Third Quarter 2021 Highlights

• Record sales of $162.6 million, an increase of 95% from the $83.4 million reported in the same period in 2020 ("Q3 2020"), due primarily to gold sales from the Yaramoko mine of $49.0 million and from the Lindero mine of $41.8 million.
• Net income of $0.2 million or $0.00 per share, compared to $13.1 million or $0.07 net income per share reported in Q3 2020. Net income was lower due primarily to $10.5 million in transaction costs related to the acquisition of Roxgold Inc., and $9.6 million settlement of the disputed royalty claim with the Mexican Geological Service ("SGM").
• Adjusted net income¹ of $22.5 million compared to $16.1 million reported in Q3 2020.
• Adjusted EBITDA¹ of $75.3 million compared to $42.2 million reported in Q3 2020.
• Free cash flow from ongoing operations¹ of $33.8 million compared to $30.1 million reported in Q3 2020.
• As of September 30, 2021, the Company had cash and cash equivalents of $135.8 million, an increase of $3.9 million from December 31, 2020.
• Silver and gold production of 1,711,881 ounces and 65,425 ounces, respectively.
• AISC¹ per ounce of gold sold of $1,270 for the Lindero Mine and $1,188 for the Yaramoko Mine. AISC^1,2 per silver equivalent ounce of payable silver sold of $15.51 and $17.66 for the San Jose Mine and Caylloma Mine, respectively.

Third Quarter 2021 Results

Sales for the three months ended September 30, 2021 were $162.6 million, an increase of 95% from the $83.4 million reported in Q3 2020. Lindero reported adjusted sales of $41.8 million from 23,559 ounces of gold sold. Yaramoko reported adjusted sales of $49.0 million from 27,494 ounces of gold sold. San Jose reported adjusted sales of $43.7 million, a decrease of 32% from the $64.7 million reported in Q3 2020 due to decreases in the price of silver and a 24% and 21% decrease in the volume of silver and gold ounces sold, respectively. Caylloma reported adjusted sales of $28.0 million, a 49% increase from the $18.8 million reported in Q3 2020 due primarily to a 36% increase in the volume of silver sold, and increases in the volume and price of lead and zinc sold.

Operating income for the three months ended September 30, 2021 was $21.8 million, a decrease of $6.7 million compared to Q3 2020. The decrease was due primarily to lower sales at the San Jose mine and the $9.6 million settlement of the disputed royalty claim with the SGM plus value added tax paid to the SGM, offset partly by Lindero and Yaramoko's contribution to operating income of $10.3 million and $10.0 million respectively.

Net income for the three months ended September 30, 2021 was $0.2 million, a $12.9 million decrease from the $13.1 million net income reported in Q3 2020, primarily due to lower operating income and $10.5 million in transaction costs related to the acquisition of Roxgold Inc. The effective tax rate for the quarter was 98%.

Adjusted EBITDA for the three months ended September 30, 2021 was $75.3 million, an increase of $33.1 million compared to $42.2 million reported in Q3 2020. The increase reflects Lindero and Yaramoko´s contribution to adjusted EBITDA of $21.8 milion and $25.8 million, as well as higher EBITDA at Caylloma.

Free cash flow from ongoing operations for the three months ended September 30, 2021 was $33.8 million compared to $30.1 million in Q3 2020.

Liquidity

As of September 30, 2021, the Company had cash and cash equivalents of $135.8 million, an increase of $3.9 million from December 31, 2020.

On November 4, 2021, the Company entered into a fourth amended and restated credit agreement, effective as of November 5, 2021, which converts the Company's prior non-revolving and revolving facility into a revolving term credit facility in the amount of $200.0 million, subject to the conditions set out below, with a term of four years and a step down to $150.0 million after three years.

On closing of the amended credit facility, $120.0 million was available for drawdown and was drawn down in full. If a new environmental impact authorization for the San Jose mine ("San Jose EIA") (See news release dated October 25, 2021) has not been approved or the existing San Jose EIA has not been extended by January 23, 2022, the availability of the amended credit facility will be reduced to $100.0 million. The total amended credit facility of up to $200.0 million will only become available upon receipt of the new San Jose EIA approval or San Jose EIA extension.

On November 10, 2021, Minera Cuzcatlan received written notification from SEMARNAT that its application, made in May 2021, for a 10 year extension to its Environmental Impact Authorization for the San Jose Mine which expired on October 23, 2021 had been denied. SEMARNAT denied the application for the extension citing a pending evaluation by SEMARNAT related to the regularization of ancillary infrastructure at the mine site. In addition, it cited non receipt of requested information, which the Company has already provided to the authority. The Company is reviewing the reasons for the denial with its advisors, but believes that it is fundamentally in compliance with all material aspects of the San Jose EIA and is entitled to an extension.

The San Jose mine is currently operating under the protection of the Mexican courts which allows the continued operation of the San Jose mine beyond the expiry date of the EIA. Minera Cuzcatlan has the right and intends to appeal the decision of SEMARNAT and will continue to pursue all legal protection available to it in order to continue to operate pending the appeal of the decision of SEMARNAT.

Under the terms of the amended credit facility, the Company must obtain by November 20, 2021 a permanent injunction or equivalent protection, in form and substance acceptable to the lenders acting reasonably, which allows the Company to continue to operate the mine.

Lindero Mine, Argentina

During the third quarter of 2021, the onsite impact of COVID-19 diminished resulting in less disruptions to the operations, with the company screening 74 positive cases compared to 160 cases registered in the second quarter of 2021. To date, including company and contractor personnel, 94% of the workforce has been vaccinated with one dose and 40% with two doses. The government of Argentina has announced that travel restrictions will start to ease in November, which should improve lead times and onsite technical assistance from foreign vendors.

In the third quarter of 2021, a total of 1,387,134 tonnes of ore were placed on the leach pad averaging 1.10 g/t gold containing an estimated 49,247 ounces of gold. Total gold production for the quarter was 26,235 ounces, comprised of 24,318 ounces in doré and an increase of 1,918 ounces of gold-in-carbon (GIC) inventory.

Cash cost per gold ounce sold was $646, as the mine continues to ramp-up production.

All-in sustaining cash costs per gold ounce sold was $1,270 during the quarter and $1,182 year to date, slightly above the Company's updated guidance for the full year, due primarily to timing of sustaining capital expenditures and ounces sold. The Company expects the full year results to be in-line with the updated guidance.

Total capital expenditures of $10.7 million during the quarter were related primarily to the ADR plant expansion and completion of phase 1B of the leach pad construction.

Yaramoko Mine Complex, Burkina Faso

The Yaramoko Mine produced 28,751 ounces of gold in the third quarter of 2021 with an average gold head grade of 7.28 g/t; slightly below the plan for the quarter.

Unplanned downtime due to the premature changeout of a SAG mill pinion bearing in August contributed to slightly lower mill throughput of 126,677 tonnes in the quarter against a plan of 127,917 tonnes. This, in addition to some necessary re-sequencing of production stopes at the 55 Zone, due to isolated ground conditions causing bridging which resulted in a reprioritization of lower grade stopes, contributed to the minor production shortfall.

These issues have been remedied and are not expected to continue nor affect fourth quarter performance which is expected to be in line with guidance.

Cash cost per gold ounce sold was $720, which was above plan, primarily due to lower production.

All-in sustaining cash cost per gold ounce sold was $1,188, slightly above the Company's updated guidance, due primarily to the lower production and timing of sustaining capital expenditures. The Company expects the full year results to be in-line with the updated guidance.

Capital expenditures of $8.0 million during the quarter related primarily to underground mine development costs.

San Jose Mine, Mexico

The San Jose Mine produced 1,436,658 ounces of silver and 8,910 ounces of gold during the three months ended September 30, 2021, which represents a decrease of 25% and 22%, respectively, compared to Q3 2020. The decrease was due primarily to lower grades.

The production cash cost per tonne for the three months ended September 30, 2021 was $77.52 an increase from the $67.60 per tonne in Q3 2020 primarily due to lower tonnes milled.

The all-in sustaining cash cost of payable silver equivalent for the three months ended September 30, 2021 was $15.51 per ounce, an increase from the $11.39 per ounce in Q3 2020. The increase was due primarily to higher production cash costs as noted above, increase in brownfields capital expenditures, higher royalties, and lower silver equivalent sales.

Capital expenditures totaled $7.6 million for the three months ended September 30, 2021, an increase from the $4.8 million in Q3 2020. The increase was due to the impact of COVID-19 in Q3 2020, whereby brownfields capital expenditures at the operations were significantly reduced.

Caylloma Mine, Peru

The Caylloma Mine produced 275,223 ounces of silver, 8.2 million pounds of lead and 12.4 million pounds of zinc during the three months ended September 30, 2021, an increase of 31%, 23%, and 21% respectively compared to Q3 2020. The increased metal production was due to higher head grades for all metals and higher recoveries for silver and lead. Gold production for the third quarter of 2021 totaled 1,529 ounces with an average head grade of 0.48 g/t, an increase of 12% over Q3 2020.

The production cash cost per tonne for the three months ended September 30, 2021 was $86.04, an increase from the $76.80 in Q3 2020. The increase was due primarily to higher mining costs on increased mine preparation activities and higher planned maintenance costs in the processing plant.

The all-in sustaining cash cost of payable silver equivalent for the three months ended September 30, 2021 was $17.66 per ounce, a decrease from the $19.53 per ounce in Q3 2020. The decrease was due primarily to higher silver equivalent sales, offset partly by the higher production cash cost per tonne as noted above.

Capital expenditures totaled $4.8 million for the three months ended September 30, 2021, an increase from the $1.3 million in Q3 2020. The increase was primarily due to the impact of COVID-19 during Q3 2020, whereby capital expenditures were significantly reduced.

On October 16, 2021, the Company signed a community support with the Municipality of Caylloma, which includes a voluntary payment of 2.2 million Peruvian soles per year over the four year term agreement, starting in the fourth quarter of 2021. The resources will be used for the implementation of programs or projects for the sustainable development of the Caylloma District.
