Lindero reported sales of $34.2 million from 18,924 ounces of gold ounces sold. San Jose reported sales of $60.3 million, an increase of 98% from the $30.5 million reported in Q2 2020 due to a 58% and 52% increase in the volume of silver and gold ounces sold, respectively, and higher realized metal prices, primarily silver. Caylloma reported sales of $26.0 million, a 86% increase from the $14.0 million reported in Q2 2020 due to higher realized prices, primarily zinc and silver, and higher volumes of metal sold, primarily gold.

Operating income for the three months ended June 30, 2021 was $35.9 million, an increase of $37.2 million compared to Q2 2020. The increase was due primarily to higher silver and gold prices, and Lindero's contribution to mine operating income of $7.2 million.

Net income for the three months ended June 30, 2021 was $16.2 million, a $21.9 million increase over the $5.7 million net loss reported in Q2 2020. The effective tax rate for the quarter was 43%.

Adjusted EBITDA for the three months ended June 30, 2021 was $54.9 million, an increase of $45.5 million compared to the $9.4 million reported in Q2 2020. The increase reflects Lindero´s contribution to adjusted EBITDA of $16.2 million as well as higher EBITDA at San Jose and Caylloma.

Free cash flow from ongoing operations for the three months ended June 30, 2021 was $18.5 million compared to $0.2 million in Q2 2020.

Liquidity

As of June 30, 2021, the Company had cash and cash equivalents of $121.8 million, a decrease of $10.1 million from December 31, 2020, primarily due to a $35.3 million promissory note that was provided to Roxgold to cover a portion of the expected acquisition closing costs.

The Company's $120.0 million credit facility remains fully drawn as of June 30, 2021 and is set to expire on January 26, 2022. It is contemplated that during the third quarter of 2021, the Company's existing credit facility will be replaced by a new credit facility in the increased amount of $200.0 million pursuant to an amended and restated credit agreement with the Company's existing and new lenders.

Lindero Mine

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 continued 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 of 2021 and had a significant impact on the operation´s performance as 163 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 delays 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 of 2021, 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.

Cash cost per gold ounce sold was $673, as the mine continues to ramp-up production.

All-in sustaining cash costs per gold ounce sold was $1,214, in line with the Company's original guidance for the first half of the year of between $1,130 and $1,335 per gold ounce sold, due primarily to the timing of sustaining capital expenditures.

In the second quarter of 2021, sustaining capital expenditures included $2.3 million of capitalized stripping, $1.7 million for leach pad expansion, and $1.2 million for the ADR plant.

The Company´s updated gold production guidance range for Lindero of between 90 and 110 thousand ounces reflects the direct and indirect impact of COVID-19 related challenges. These factors have been evaluated and their effect considered for the second half of the year (refer Fortuna news release dated July 19, 2021).

San Jose Mine

The San Jose Mine produced 1,624,394 ounces of silver and 10,266 ounces of gold during the three months ended June 30, 2021, which represents an increase of 58% and 54%, respectively, compared to Q2 2020. The increase was due primarily to 68% higher tonnes milled in the second quarter of 2021 compared to Q2 2020, which was impacted by the 54-day shutdown of operations from government mandated restrictions in response to COVID-19.

The production cash cost per tonne for the three months ended June 30, 2021 was $75.50 an increase from the $65.98 per tonne in Q2 2020 primarily due to a stronger US dollar during Q2 2020 and higher planned mining preparation activities during the current quarter.

The all-in sustaining cash cost of payable silver equivalent for the three months ended June 30, 2021 was $13.61 per ounce, an increase of 23% compared to $11.04 per ounce in Q2 2020. The increase was due primarily to higher production cash costs as noted above, increases in sustaining and brownfields capital expenditures, and higher royalties, offset partly by higher silver equivalent sales.

Capital expenditures totalled $6.9 million for the three months ended June 30, 2021, an increase of 364% compared to Q2 2020, as COVID-19 restrictions more significantly impacted operations during Q2 2020.

Caylloma Mine

The Caylloma Mine produced 268,428 ounces of silver, 8.1 million pounds of lead and 11.8 million pounds of zinc during the three months ended June 30, 2021, an increase of 10%, 20%, and 7% respectively compared to Q2 2020. The increased metal production was due to higher head grades. Gold production for the second quarter of 2021 totaled 1,261 ounces with an average head grade of 0.42 g/t.

The production cash cost per tonne for the three months ended June 30, 2021 was $91.15, an increase of 22% compared to Q2 2020. The increase was due primarily to Q2 2020 having lower costs than planned due to a shutdown of mining operations in April 2020 without any significant impact on tonnes processed during the quarter.

The all-in sustaining cash cost of payable silver equivalent for the three months ended June 30, 2021 was $18.45 per ounce, an increase of 20% compared to the $15.34 per ounce in Q2 2020. The increase was due primarily to higher production cash costs as noted above, increases in sustaining and brownfields capital expenditures, and higher royalties, offset partly by higher silver equivalent sales.
