VANCOUVER, British Columbia, July 12, 2023 (GLOBE NEWSWIRE) — Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) reports production results for the second quarter of 2023 from its five operating mines in West Africa and Latin America.

Q2 2023 Production highlights

Article content

Article content

Gold production of 64,348 ounces included contributions of 25,456 ounces from the Lindero Mine, 29,002 ounces from the Yaramoko Mine, and 4,023 ounces from the Séguéla Mine, our newest flagship mine located in Côte d´Ivoire. The higher year-over-year gold production is primarily due to the start of production at the Séguéla Mine which offset lower gold and silver production from the San Jose Mine, which was impacted by a 15-day illegal union worker blockade (refer to Fortuna news release dated June 5, 2023).

Consolidated gold and silver production for the first six months of 2023 totaled 124,440 ounces and 2.8 million ounces, respectively. Fortuna reiterates its 2023 annual production guidance range of 6.3 to 6.9 million ounces of silver and 282 to 320 thousand ounces of gold or between 412,000 and 463,000 gold equivalent ounces, including lead and zinc by-products² (refer to Fortuna news release dated January 17, 2023).

Séguéla Mine, Côte d’Ivoire: First gold pour at our new flagship mine took place on May 24, 2023

Notes:

Article content

In the second quarter of 2023, mine production at the Antenna pit totaled 383,100 tonnes of mineralized material at a strip ratio of 2.3:1, averaging 2.35 g/t Au and containing an estimated 28,958 ounces of gold. Initial mill feed was sourced from lower grade thin saprolite with the operation changing the feed as mining progressed into higher grade transitional and fresh mineralized material. At the plant, 109,605 tonnes of ore were processed at an average grade of 1.56 g/t  Au producing 4,023 ounces of gold.

Grade control infill drill program

Prior to the commencement of mining, grade control drilling was undertaken at the Antenna pit. Results from this initial campaign of grade control drilling have been positive in terms of reconciliation against the geological model with an increase in tonnes and gold grade of 2 percent and 13 percent, respectively, for an overall increase in contained gold ounces of 15 percent.

Mining

Mining of mineralized material commenced in the second quarter with first ore being delivered to the run of mine (ROM) pad on April 2. Mining began in free dig oxide saprolite with the first blast in transitional material taking place on May 28. Waste mined was used to construct and expand the ROM pad and to commence construction of the next lift of the tailings storage facility. Total movement of waste and ore was 877,143 and 383,100 tonnes, respectively.

During the second quarter, site preparation and access road construction to the Ancien pit was undertaken along with initiating the first grade control drilling program for this deposit. The high grade Ancien pit is planned to commence contributing mill feed in the fourth quarter of this year.

Article content

The mine is operating with a complete fleet consisting of eight 100-ton CAT 777 trucks, four excavators, four production/grade control drill rigs, and ancillary equipment.

Antenna pit mining activities

Processing

The processing plant consists of a single stage crushing circuit with crushed ore being fed to a SAG mill followed by conventional carbon-in-leach and gravity recovery circuits prior to electro winning and smelting of gold doré.

First ore was fed to the SAG mill on April 26 with first gold pour occurring ahead of schedule on May 24. After five weeks of successful ramp up activities, process plant throughput has progressively increased to reach nameplate capacity of 154 t/hr at the end of the quarter.

Article content

Average gold recovery in the initial weeks of the operations´ ramp up phase was 89.6 percent, tracking as per expectations and marginally below design recovery of 94 percent. Management expects the processing plant will achieve design recovery parameters during the third quarter, as mine feed transitions into fresh and transitional ore and the processing plant throughput becomes stable at nameplate capacity.

Yaramoko Mine, Burkina Faso: On-track to meet upper end of annual guidance range

Article content

Notes:

In the second quarter of 2023, the Yaramoko Mine produced 29,002 ounces of gold at an average head grade of 6.51 g/t Au, an 18 and 20 percent increase, respectively, compared to the comparable period in 2022. Production benefitted from higher grades mined and an increase in milled tonnes. Better than expected grades were sourced from the extension of the deposit beyond the current resource boundary on the western side of the 55 Zone. Production at Yaramoko is expected to be at the upper end of annual guidance range. In light of the recent success encountering extensions of mineralization on the fringes of the resource boundary at Zone 55, the Company expects to provide a Mineral Reserve and Mineral Resource update before year end.

Article content

Access to the underground mine was impacted for 27 days in April due to a failure of the Armtec tunnelling structure at the mine portal (refer to Q1 2023 MD&A). Throughout this period, processing operations were maintained by milling surface ore stockpiles. Underground mine production resumed on May 1.

Gold production for the first six months of 2023 totaled 55,439 ounces.

Latin America Region

Lindero Mine, Argentina: On-track to meet annual production guidance

Notes:

During the second quarter of 2023, mine production was 0.8 million tonnes of mineralized material with a stripping ratio of 2.69:1. The stripping ratio for the second quarter of 2023 is aligned with the operation’s plan for the year of 1.17:1 (refer to Lindero Mine and Arizaro Project technical report with an effective date of December 31, 2022). A total of 1.5 million tonnes was placed on the leach pad containing 29,984 ounces of gold averaging 0.62 g/t Au.

Article content

Gold production in the quarter was 25,456 ounces, comprised of 24,599 ounces of doré, an estimated 731 ounces of gold contained in fine carbon, and 126 ounces contained in copper concentrate. Gold production for the second quarter of 2023 is 12 percent lower when compared to the second quarter of 2022 mainly due to the lower head grade of mineralized material placed on the leach pad that is aligned with the Mineral Reserves and mining sequence.

Gold production for the first six months of 2023 totaled 50,714 ounces.

San Jose Mine, Mexico: Production impacted by 15-day illegal blockade

Article content

Notes:

The San Jose Mine produced 0.96 million ounces of silver at an average head grade of 168 g/t Ag and 5,778 ounces of gold at an average head grade of 1.02 g/t Au; reflecting a 31 and 30 percent decrease in production when compared to the second quarter 2022. The processing plant milled 194,887 tonnes at an average of 2,633 tonnes per day.

The decrease in production is explained by the 15-day full shutdown of operations due to the illegal blockade by the workers’ union. This reduced planned production for the quarter by 47,200 tonnes and impacted mine preparation, delaying access to higher grade stopes planned in the quarter. The Company has adjusted the mine plan to access these stopes in the third quarter and expects to achieve the lower end of annual guidance.

Article content

Silver and gold production for the first six months of 2023 totaled 2.3 million ounces and 14,009 ounces, respectively.

Caylloma Mine, Peru: Strong performance, on-track to meet upper end of annual guidance

Notes:

Article content

The Caylloma Mine produced 305,296 ounces of silver at an average head grade of 84 g/t Ag in the second quarter of 2023, a 14 percent increase from the comparable period in 2022. Production has benefitted from higher grade stopes at the lower levels of the Animas vein. Silver production for the first six months totaled 0.59 million ounces.

Zinc and lead production was 14.0 and 10.2 million pounds at an average head grade of 5.18 % and 3.72 %, respectively; a 29 and 34 percent increase in production from the comparable period in 2022. Increased production is the result of higher head grades sourced from lower levels at the Animas vein.

Zinc and lead production for the first six months totaled 27.1 million pounds and 19.7 million pounds, respectively.
