Lindero Mine, Argentina

Argentina suffered a surge of COVID-19 during the second quarter of 2021 with the infection rate peaking

at 41,000 cases per day. Extended nationwide COVID -19 related travel restrictions continue d to limit

onsite access to foreign vendor support affecting ramp up activities at Lindero.

The COVID-19 infection rate at Lindero increased during the second quarter and had a significant impact

on the operation´s performance as 160 personnel tested positive, representing 18 percent of the

workforce. During the quarter, the company intermittently voluntarily suspended onsite operations for a

total of 16 days which directly impacted ramp up progress and reduced the amount of ore delivered to

the heap leach pad. Strict government mandated travel restrictions have led to disruptions in the hiring

and movement of skilled personnel and delay s in access to foreign vendor support , which resulted in

higher mechanical downtime leading to lower tonnes of processed ore being delivered to the leach pad.

In the second quarter, a total of 1,477,000 tonnes of ore were placed on the leach pad averaging

0.95 g/t gold containing an estimated 44,889 ounces of gold.

Total gold production for the quarter was 19,521 ounces, 73 percent of the plan, comprised of

18,726 ounces in doré and 794 ounces of gold-in-carbon (GIC) inventory.

Mining

A total of 1 ,817,000 tonnes of ore were mined in the second quarter of 2021 at a strip ratio of 0.9:1 ,

20 percent below plan. M ine waste movement increased 3 4 percent compared to the first quarter of

2021, in line with expectation.

Mine reconciliation and metallurgical performance

Reconciliation of tonnes, grade and gold ounces mined for the second quarter indicate a good correlation

with the reserve model with differences of less than five percent for all parameters.

Gold leaching response as well as reagent consumption was within the expected parameters for the

granulometric composition and metallurgical types of ore placed on the leach pad.

Processing

In the second quarter of 2021, a total of 1,477,000 tonnes of ore were placed on the leach pad at

0.95 g/t gold, 20 and 1 0 percent below plan , respectively. All processing activities were impacted

negatively by the direct and indirect downtimes related to the surge in C OVID-19 cases and government

restrictions. Lower grade is explained by the extraction of fewer tonnes from the pit than was planned,

resulting in reduced access to higher gr ade ore than was scheduled, and grade dilution as the operation

attempted to selectively mine higher-grade ore from lower -grade ore during th is period to offset

temporary shortfalls in gold stacked.

Trucked ore from the run of mine and coarse stockpiles placed on the leach pad totaled 801,000 tonnes,

32 percent higher than plan. Trucking of coarse ore to the leach pad was a temporary measure during the

first half of the year to offset the lower tonnage of agglomerated ore; resulting in a 15 percent decrease,

in respect to plan and guidance, of recoverable gold ounces on the heap during this period.

Primary and secondary crushing averaged 1 4,870 tonnes per day during the quarter, representing

79 percent of design capacity of 18,750 tonnes per day.

The tertiary-HPGR crusher, agglomeration plant, and stacking system throughput averaged 9,510 tonnes

per day in the quarter representing 51 percent of design capacity and a 25 percent increase compared to

the previous quarter. In June, ore stacking averaged 12,600 tonnes per day, representing 67 percent of

design capacity peaking at 18,390 tonnes per day, 98 percent of design capacity.

The company has worked to address ramp up challenges in the tertiary crushing-agglomeration-stacking

circuit with the in-country arrival of specialist support which was delayed due to COVID-19 travel

restrictions. The operation expects to complete the planned ADR plant expansion and achieve full

production capacity early in the fourth quarter of 2021.

SART plant ramp up work resumed in June at a pregnant solution flow rate of 100 to 150 cubic meters per

hour, 25 percent of design capacity, regarded as sufficient to manage soluble copper levels in the ADR

plant at this time . The SART plant is expected to achieve design capacity of 400 cubic meters per hour

during the second half of the year.

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 t he 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

The San Jose Mine produced 1,624,394 ounces of silver and 10,266 ounces of gold in the second quarter

of 2021 with average head grades for silver and gold of 205 g/t and 1.30 g/t, respectively; 4 percent above

and in line with plan.

Caylloma Mine, Peru

In the second quarter of 2021, t he Caylloma Mine produced 268,428 ounces of silver with an a verage

head grade of 76 g/t, in line with plan.

Gold production was 1,261 ounces, an increase of 183 percent with respect to the second quarter of 2020.

Caylloma’s gold production continues to exceed plan with average grades experienced in the second

quarter expected to continue throughout the year. The mine geology team has confirmed the continuity

of this higher-grade zone as related to the intersection of the Animas NE and Nancy veins with modeling

work to define this ore shoot completed.

Lead and zinc production for the second quarter of 2021 was 8,143,876 pounds and 11,763,866 pounds

with average head grades for lead and zinc of 3.09% and 4.58%, respectively; 8 percent and 9 percent

above plan.

5. Refer to Lindero Mine AISC Guidance section in 2021 Guidance Outlook below

2021 Guidance Outlook

Lindero Mine, Argentina

Production guidance

Lindero´s updated gold production guidance range of between 90 and 110 thousand ounces reflects a

decrease of 50,000 ounces with respect to both the lower and upper range of the production guidance

disclosed on January 19, 2021 . The decrease in production is a consequence of the direct and indirect

impacts of the increase in COVID-19 positive cases in Argentina and in the workforce at Lindero, stricter

government mandated trave l restrictions which have caused delays in the ramp up of activities , and

challenges related to attempting to selectively mine and se parate higher-grade material, as discussed

above for the second quarter results. Operational impacts caused by these factors have been evaluated

and their effect considered for the second half of the year.

AISC guidance

Lindero´s updated AISC per ounce of gold between US$1,010 and US$1,190 reflects an increase of

38 percent with respect to both the lower and upper range of the AISC guidance disclosed at the beginning

of the year. The increase is a consequence of projected lower gold production and higher sustaining capex

related to the expansion of the ADR plant.

San Jose Mine, Mexico

At San Jose, the company reiterates the mine´s production and AISC guidance disclosed on January 19,

2021. COVID-19 related protocols set in place h ave been reviewed and adjusted to continue mitigating

the impacts of positive cases in the workforce. The ongoing vaccination campaign in the state of Oaxaca

in addition to the company´s strengthened health procedures are anticipated to contribute to containing

the COVID-19 infection rate at the operation.

- 6 -

Caylloma Mine, Peru

At Caylloma, despite registering COVID-19 positive cases in the workforce during the first half of the year,

the mine´s performance has exceeded expectations as a result of an efficient allocation of the operation´s

resources and coarse ore stockpile management. The company reiterates the mine´s production and AISC

guidance disclosed on January 19, 2021, including lead and zinc production of 29 to 32 million pounds and

44 to 49 million pounds, respectively. In addition, gold production of 4 to 5 thousand ounces for the year

has been included in the annual consolidated production guidance to take into account the higher-grade

zone related to the intersection of the Animas NE and Nancy veins.

Yaramoko Mine, Burkina Faso

There were no major COVID-19 related impacts at the Yaramoko Mine during the second quarter of 2021.

Gold production guidance for the second half of the year assumes there will be no significant disruptions

of operations associated with COVID-19.

Annual planned m ine d evelopment meters are projected to increase , driven by a stoping sequence

rescheduling associated with lower grades encountered during the second quarter of the year . The

increase in development meters is expected to contribute to achieving second half of the year gold

production guidance at an estimated AISC per ounce of gold of US$990 to US$1,150.

Séguéla Gold Project, Côte d’Ivoire

At the Séguéla Project, the company expects to commence negotiations on the Project Mining Convention

with the government early in the third quarter. At the project site, the accommodation village is projected

to be ready for occupancy in the fourth quarter of 2021. Key contracts with plant EPC and bulk earthworks

contractors are close to being finalized. In order to not affect the critical path of the project, the Board of

Directors of the company has approved an early works budget of US$11.5 million to commence detailed

engineering work and procure long lead items such as the SAG mill. The company expects to make a

construction decision during the third quarter.

Exploration Outlook

Fortuna continues to advance its robust pipeline of Brownfield and Greenfield exploration projects in

West Africa and the Americas. The company will be providing a comprehensive exploration update in the

third quarter.

West Africa

Exploration in Côte d’Ivoire during the second half of the year will focus on infilling and extending the new

Sunbird discovery at Séguéla, where mineralization has now been delineated over a strike length of more

than 1,000 meters . Drilling will also continue the delineation of the high -grade Koula underground

inventory, while also following up on the recent high grades intersected in scout reverse circulation drilling

at Gabbro North. Further afield, several extensive soil and termite geochemistry anomalies will be tested

with aircore drilling at Fortuna’s Kadyoha and Dianra Nord prospects, some 140 kilometers to the north-

east of Séguéla.

- 7 -

In Burkina Faso, delineation and step out drilling will continue in the second half of the year at Boussoura

after the conclusion of the annual rainy season in August . Drilling will focus on defining the Fofora Main

and VC2 deposits, and delineating additional mineralization at VC3 and VC5. Similarly, definition drilling

in the second half of the year at Galgouli and exploration drilling of mineralization identified at several

nearby prospects will continue. At Yaramoko, activities will continue to support advancing the 109 Zone

surface prospect, as well as target testing and delineation across the wider Yaramoko property.

Americas

Fortuna budgeted US$21 million for its 2021 exploration program, consisting of 69,000 meters of surface

and underground diamond drilling, supporting ground geophysical programs, and underground

development. As of the end of June, the exploration teams had completed a total of 23,400 meters of

drilling, 34 percent of plan. The remainder of the planned meters and budget at the mines and two

additional Greenfields projects will be realized throughout the second half of 2021 using up to 12 core

rigs. Fortuna also maintains a wide-ranging reconnaissance program in Mexico.
