Production for the full year was impacted by a 54-day government mandated suspension in the second quarter of 2020 related to the COVID-19 pandemic (refer to Fortuna news release dated May 26, 2020).
Caylloma Mine, Peru
In the fourth quarter of 2020, the Caylloma Mine produced 263,921 ounces of silver with an average head grade of 73 g/t. Silver production for the full year 2020 totaled 968,111 ounces, an increase of 3 percent over 2019, with an average head grade of 72 g/t.
Gold production for the fourth quarter of 2020 was 1,827 ounces with an average head grade of 0.60 g/t. Gold production for the full year 2020 totaled 4,109 ounces, an increase of 150 percent over 2019, with an average head grade of 0.41 g/t. Gold production was positively impacted by unusual higher head grades compared to the reserve model at the Animas NE vein. The exploration team is carrying out work to understand the occurrence and controls of these higher-grade zones that can carry gold grades as high as 10 g/t.
Lead and zinc production for the fourth quarter of 2020 was 8,426,068 pounds and 12,434,072 pounds with average head grades for lead and zinc of 3.16% and 4.69%, respectively. Base metal production for the full year totaled 45,545,299 pounds of zinc, in line with production in 2019, and 29,627,923 pounds of lead, an increase of 3 percent over 2019. Average head grades for lead and zinc for the year were 3.00% and 4.61%, respectively.
Production for the full year was not impacted despite government mandated restrictions, the implementation of Company protocols related to COVID-19 (refer to Fortuna news release dated March 17, 2020), and a voluntary three-week suspension of operations in July (refer to Fortuna news release dated July 28, 2020).
Lindero Mine, Argentina
In the fourth quarter of 2020, a total of 950,000 tonnes of ore were placed on the heap leach pad averaging 1.13 g/t gold, containing an estimated 34,000 ounces of gold. First gold was poured at Lindero in October 2020, and doré production for the fourth quarter of 2020 was 13,435 ounces of gold. For full year 2020, a total of 1.61 million tonnes of ore have been placed on the heap leach pad averaging 1.00 g/t gold, containing an estimated 52,000 ounces of gold.
The table below details material movements from the pit as estimated from the grade control model versus the Mineral Reserve block model for the fourth quarter of 2020. Reconciliation of the estimate indicates a good correlation with 3.9 percent more gold ounces mined than predicted and gold grade in line with expectation.
Gold production and Sales
The Company produced 13,435 ounces of gold in 2020, which is in line with its revised production forecast of between 13,000 to 15,000 ounces (refer to Fortuna news release dated November 12, 2020). Sales for the year totaled 10,935 ounces.
A total of 3.78 million tonnes of ore were mined in 2020 at a strip ratio of 1.05:1. Mining and equipment performance are in line with design parameters and support the operation´s processing capacity of 18,750 tonnes per day.
During 2020, a total of 1.6 million tonnes of coarse ore were placed on the heap leach pad at an average gold head grade of 1.00 g/t containing a total of 52,000 ounces of gold. Average ore crushing throughput rate for the year was 8,831 tonnes per day. Recovery of gold from the heap leach was in line with expectations based on metallurgical testing of coarse ore with an estimated 16,687 ounces of gold leached as of December 31, 2020.
In the fourth quarter of 2020, primary and secondary crusher throughput averaged 10,406 tonnes per day with the ramp up schedule progressing according to plan, achieving 75 percent of the 18,750 tonnes per day design capacity in December 2020. The operation is fine-tuning the crushing system with a focus on screens, chutes, and belt conveyors in order to ramp up crushing throughput to the design capacity.
Commissioning of the HPGR, agglomeration plant, and stacking system was completed in mid-December with all systems in the ramp up phase. The operation is transitioning from placing coarse ore on the heap leach pad with trucks to placing tertiary crushed ore via the stacking system, which is expected to increase heap gold recovery from an estimated 50 percent to 78 percent over a 90-day period based on metallurgical column test results.
The SART plant was commissioned in mid-December and the ramp up phase commenced with the circulation of 80 cubic meters per hour of pregnant solution, approximately 20 percent of design capacity. Once design parameters are achieved, copper concentration in the pregnant solution will be reduced allowing the ADR plant to operate at design parameters.
The Company expects the ramp up phase of the entire processing circuit to be completed in the first quarter of 2021.
Construction and Sustaining capital
Construction at Lindero is substantially complete as of the end of December 2020 with construction capital expenditures projected to be within the US$320 million guidance (refer to Fortuna news release dated May 8, 2020), including remaining capital expenditures of US$2.0 million to be allocated to finalize construction of ancillary facilities and to commissioning activities. During 2020, sustaining capital of US$1.7 million was spent mainly on the purchase of spare parts for major equipment.
2021 Consolidated Production and Cost Guidance
The Company’s production and cost guidance set out below for 2021 assumes that operations will continue during the year without any major interruptions related to COVID-19. At each of our mine sites, health protocols are in place for control, isolation and quarantine, as necessary, and these continue to be reviewed and adjusted accordingly based on the circumstances at each location. The Company’s focus is the health and safety of the workforce and on measures to prevent and manage the transmission of COVID-19 amongst the workforce and the communities in which Fortuna operates.
2021 Guidance Highlights
San Jose Mine, Mexico
At the San Jose Mine, the operation plans to process 1.13 million tonnes averaging 196 g/t Ag and 1.26 g/t Au. Capital investment is estimated at US$23.4 million, including US$13.4 million for sustaining capital expenditures and US$10.0 million for Brownfields exploration programs.
Major sustaining capital investment projects include:
- Mine development: US$6.9 million
- Dry stack expansion: US$1.8 million
- Equipment and infrastructure: US$1.8 million
- Infill drilling: US$0.9 million
Caylloma Mine, Peru
At the Caylloma Mine, the operation plans to process 530,000 tonnes averaging 74 g/t Ag, 2.87% Pb, and 4.30% Zn. Capital investments are estimated at US$21.7 million, including US$15.2 million for sustaining capital expenditures and US$4.7 million for Brownfields exploration programs.
Major sustaining capital investment projects include:
- Mine development and infill drilling: US$5.9 million
- Tailings dam expansion: US$4.7 million
- Electric system upgrade: US$1.9 million
- Infrastructure: US$1.5 million
Lindero Mine, Argentina
At the Lindero Mine, the operation plans to place on the leach pad 6.3 million tonnes of ore averaging 1.08 g/t Au, containing an estimated 218,000 ounces of gold. Capital investments are estimated at US$20.8 million, including US$20.5 million for sustaining capital expenditures and US$0.3 million for Brownfields exploration programs.
Gold production is planned to ramp-up throughout the year to reach the annual guidance range of between 140,000 to 160,000 ounces with approximately two thirds of annual production anticipated to be achieved in the second half of 2021.
The ramp up phase of the HPGR, agglomeration, and stacking system is proceeding according to schedule, and the operation expects to integrate the entire comminution and conveyor belt system and reach design capacity by the end of the first quarter of 2021. Throughout this period, some coarse ore will continue to be placed on the heap leach pad by truck as the operation transitions to the stacking system.
By the end of the first quarter of 2021, the operation also expects the SART plant to achieve design capacity which will reduce soluble copper in the pregnant solution, resulting in more efficient cyanide consumption and gold recovery at the ADR plant.
The operation expects to complete construction of the planned phase one expansion of the heap leach pad by the second quarter of 2021, which will provide sufficient leaching area until 2024.
Major sustaining capital investment projects include:
- Heap leach pad completion (years 1 – 3): US$7.0 million
- ADR plant expansion: US$5.0 million
- Maintenance and energy: US$4.0 million
The Company has decided to bring forward the expansion of the ADR plant from year four in the life of mine plan, due to higher projected gold production of 24,000 ounces for the initial three years compared to the original feasibility study. The expansion of the ADR will provide greater gold adsorption capacity and efficient recovery of the additional ounces.
The major components of sustaining capital, including the expansions of the ADR plant and heap leach pad, representing between 70% and 80% of the annual budget are expected to be executed in the first half of 2021.
Annual cash cost per ounce of gold for 2021 is projected between US$365 and US$430 and AISC is projected between US$730 and US$860 per ounce of gold. For the first half of the year, AISC is projected between US$1,130 and US$1,335 due to the ramp-up in gold production and sustaining capital expenditure execution in the first semester and to range between US$525 and US$615 per ounce of gold in the second half of 2021.
Projected AISC for 2021 is approximately US$200 per ounce of gold higher than was projected in our news releases dated February 20, 2020 and May 8, 2020. The main drivers of the increase, which are partially offset by reduced cost in key consumables of approximately US$25 per ounce of gold, are listed below:
- Sustaining capital expenditures: Expansion of the ADR plant and the heap leach pad represents approximately US$80 per ounce of gold.
- Export duty and mining royalty: Higher gold price assumptions represent US$20 per ounce, and a higher export duty rate of eight percent of sales, compared to five percent in the prior guidance, represents US$40 per ounce of gold
- Production cost: A ten percent increase in unit costs per tonne represents approximately US$40 per ounce of gold. The main drivers of the increase are related to COVID-19 expenses of US$2.1 million, various indirect costs of approximately US$1.8 million, and higher planned maintenance contractor services at the processing plant in 2021 of US$1.2 million.
Brownfields Exploration Outlook
The Company is expanding its exploration budget and initiatives in 2021 as the capital-intensive phase of Lindero has ended. Fortuna´s consolidated Brownfields exploration budget for 2021 for all three mines totals US$15.9 million, which includes 53,800 meters of diamond drilling and 2,170 meters of underground development. Consolidated Brownfields exploration expenses in 2020 were US$4.6 million.
San Jose Mine, Mexico
The Brownfields exploration program budget for 2021 at the San Jose Mine is US$10.9 million, which includes 33,800 meters of diamond drilling and 1,770 meters of underground development for drilling access, platforms, and services. Underground exploration drilling will focus on the shallow and deep north and south extensions of the Trinidad vein system and the sub-parallel Victoria mineralized zone, while surface drilling will test two new targets to the south and north of the mine.
Caylloma Mine, Peru
The Brownfields exploration program budget for 2021 at the Caylloma Mine is US$4.7 million, which includes 19,000 meters of diamond drilling and 500 meters of underground development for drilling access, platforms, and services. Surface and underground drilling will focus on the extensions of two ore shoots along the Animas vein, the possible extension of mineral resources along the San Cristobal silver vein located to the north of the mine and one new grassroots target located to the south of the mine.
Lindero Mine, Argentina
The Brownfields exploration program budget for 2021 at the Lindero Mine is US$320,000, which includes 1,000 meters of drilling on the Arizaro target located 3.5 kilometers to the southeast of the mine. The drilling will test for additional mineralization that could potentially contribute to Lindero’s future production.
Greenfields Exploration Outlook
Active reconnaissance exploration programs on acquired projects and evaluations of possible acquisitions in Mexico, Argentina, and select other jurisdictions will continue throughout 2021. Allocated budget for greenfield exploration activities in 2021 is US$5.0 million.
Quality Assurance & Quality Control
Grade control estimates 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.

Non-GAAP Financial Measures
This news release also refers to non-GAAP financial measures, such as all-in sustaining cash cost and cash cost per tonne of processed ore. These measures do not have a standardized meaning or method of calculation, even though the descriptions of such measures may be similar. These performance measures have no meaning under International Financial Reporting Standards (IFRS) and therefore, amounts presented may not be comparable to similar data presented by other mining companies.
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. Equivalent U.S. reporting requirements are currently governed by the United States Securities and Exchange Commission ("SEC") Industry Guide 7 (“Industry Guide 7”) under the U.S. Securities Act of 1933, as amended. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC currently in effect under Industry Guide 7, and reserve and resource information contained in this news release may not be comparable to similar information disclosed by U.S. companies. In particular, the term "resource" does not equate to the term "reserves". Under the SEC's disclosure standards currently in effect under Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. While the SEC recognizes the reporting of mineral deposits which do not meet the Industry Standard Guide 7 definition of “reserve” as of February 25, 2019, the effective adoption of the Modernization of Property Disclosures for Mining Registrants, such rules are not required to be compiled with until the first fiscal year beginning on or after January 1, 2021. As a result, the SEC's disclosure standards currently in effect normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. You are cautioned not to assume that resources will ever be converted into reserves. You should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. You should also not assume that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. You are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC's disclosure standards currently in effect under Industry Guide 7 normally only permit issuers to report mineralization that does not constitute "reserves" by such standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC's disclosure standards currently in effect under Industry Guide 7, and reserves reported in compliance with NI 43-101 may not qualify as "reserves" under such SEC standards. Accordingly, information concerning mineral deposits set forth in this news release may not be comparable with information made public by companies that report in accordance with U.S. standards.
