2022 Production Highlights

• Guidance was substantially achieved on a consolidated basis for copper, nickel, and gold. Nickel and gold production achieved the top end of the guidance ranges.
  
  
• 2022 consolidated copper production was approximately 250,000 t, and total copper-equivalent consolidated production was over 390,000 t.¹
  
  
• Candelaria copper production of 152,042 t was modestly below guidance, while gold production of 86,000 oz achieved the top end of the guidance range.
  
  
• Chapada copper production of 45,739 t achieved guidance and gold production of 68,000 oz exceeded the top end of the guidance range.
  
  
• Eagle nickel production of 17,475 t and copper production of 15,895 t both achieved guidance.

Summary of 2022 Production

Three-Year Production Outlook

• Copper production is forecast to be 236,000-260,000 t on a consolidated basis in 2023. Higher consolidated copper production of 256,000-280,000 t is forecast for 2024 due mainly to mine sequencing and the planned copper grade profile at Candelaria.
  
  
• Zinc production is forecast to increase to 180,000-195,000 t on a consolidated basis in 2023, increasing further over the three-year period to reach 225,000-240,000 t in 2025. The increasing zinc production profile is primarily due to the ramp up of the Neves-Corvo Zinc Expansion Project ("ZEP"), which is expected to consistently achieve nameplate capacity during 2024.
  
  
• Consolidated gold production is forecast to be 140,000-150,000 oz in 2023 and to be relatively constant through the three-year outlook period.
  
  
• Nickel production is to be 13,000-16,000 t in 2023 and to moderate over the three-year period driven by the planned mine sequencing and nickel grade as the Eagle East and Upper Keel orebodies at Eagle are mined.

Production Outlook⁴

• Candelaria: Annual fluctuations in copper and gold production forecasts for the next three years are mainly due to sequencing of the Candelaria open pit. Ore mining from the open pit is to be primarily from the upper benches of Phase 11 in 2023, mining towards lower benches in 2024. Mining of Phase 10 is to complete and initial ore from Phase 12 is to commence in 2024.
  
  
• Over the guidance period, total mill throughput is forecast to range between 27-29 million tonnes per annum ("Mtpa"). Debottlenecking initiatives of the Candelaria plant pebble crushing circuit are planned to begin increasing mill capacity starting late 2023. Based on the planned mill feed blend and the ore hardness throughput model, annual throughput is expected to approximate 29 Mtpa commencing in 2025.
  
  
• Candelaria's 2023 copper and gold production are forecast to be modestly weighted to the first half of the year, primarily owing to mine sequencing and the resultant grade profiles.
  
  
• Chapada: Production guidance is based on the current throughput capacity of approximately 23.5 Mtpa over the three-year period with annual fluctuations primarily due to mine sequencing and the forecast copper and gold grade profiles.
  
  Ore mining is planned from the Chapada South, Southwest, Central and North pits through 2023, followed by mining of the Baru and Chapada Northeast orebodies commencing in 2024, and the North Buriti orebody commencing in 2025.
  
  Chapada's 2023 copper and gold production are forecast to be weighted to the second half of the year due to the forecast grade profiles and seasonal operating considerations. All of Chapada's gold production remains unencumbered and is to receive full market pricing.
  
  
• Eagle: Guidance incorporates mining of the Upper Keel zone in production plans, with first ore anticipated in 2024 following development in 2023. Ore mining is to continue from the Eagle and Eagle East orebodies in 2023 with priority on increasing ore from Eagle East during the second half of the year. Eagle's 2023 nickel and copper production are forecast to be modestly weighted to the first half of the year, primarily owing to mine sequencing and the resultant grade profiles.
  
  
• Neves-Corvo: Copper production guidance for the three-year period is consistent with prior expectations. The zinc production guidance reflects the slower than anticipated ramp-up to date of ZEP. Several projects are underway to enable ZEP to consistently achieve the nameplate processing capacity of 2.5 Mtpa. These include mine development, additions to increase mine ventilation capacity, and installation of a redundant SAG feeder, amongst other initiatives. Full ZEP mining and processing rates are expected to be achieved during 2024
  
  Neves-Corvo's 2023 copper production is forecast to be equally weighted throughout the year. Zinc production is forecast to increase over the course of the year as initiatives to enable ZEP to consistently achieve nameplate capacity are executed and expected to result in improved overall throughput and metal recovery rates.
  
  
• Zinkgruvan: Zinc production is forecast to increase over the three-year period with refinement of operating plans. Zinc head grades are expected to increase over the period on mine sequencing, and metal recovery rates and concentrate grades are anticipated to improve with completion of the sequential flotation project in mid-2023. Zinkgruvan's 2023 zinc and copper production are forecast to be modestly weighted to the second half of the year, primarily owing to mine sequencing and the resultant grade profiles.

2023 Cash Cost⁶ Guidance

• Candelaria: cash cost is forecast to be $1.80/lb - $1.95/lb of copper, after by-product credits. The cash cost is expected to benefit from an approximately 50% reduction in electricity rates as a new Power Purchase Agreement (PPA) commenced at the beginning of the year. The PPA also ensures a minimum of 80% renewables in the energy mix, prioritizing wind and solar. By-product credits have been adjusted for the terms of the streaming agreement.
  
  
• Chapada: cash cost is forecast to be $2.55/lb - $2.75/lb of copper in 2023, after unencumbered gold by-product credits. The forecast increase in Chapada's cash costs compared to 2022 reflects mainly higher consumable costs and lower production volumes. Effects of copper stream agreements are reflected in the realized copper revenue.
  
  
• Eagle: cash cost is forecast to be $1.50/lb - $1.65/lb of nickel in 2023, after by-product copper credits. The forecast increase compared to 2022 is primarily a reflection of planned lower production volumes.
  
  
• Neves-Corvo: cash cost is forecast to be $2.10/lb - $2.30/lb of copper in 2023, after zinc and lead by-product credits. The cash cost is expected to continue to improve as zinc and lead production volumes increase.
  
  
• Zinkgruvan: cash cost is forecast to be $0.60/lb - $0.65/lb of zinc, after copper and lead by-product credits, consistent with 2022 levels.

2023 Capital Expenditure Guidance

• Capital expenditures are forecast to total $1,100 million on a 100% basis, including expansionary capital expenditures[9] on the Josemaria Project. The majority of sustaining capital expenditures are for open pit waste stripping, underground mine development, tailings storage facility ("TSF") and water management works.

• Candelaria: Capital expenditures at Candelaria in 2023 are forecast to total $400 million. Of this, capitalized waste stripping is forecast to be $185 million, and underground mine development, including ramp works, to be approximately $55 million. Capital expenditure for mobile and mine equipment is forecast to be $55 million, and $55 million is estimated for the continued building of the Los Diques TSF. Pebble crushing debottlenecking capital expenditures are forecast to be approximately $8 million in 2023 and completed during the year.
  
  
• Chapada: Capital expenditures at Chapada in 2023 are forecast to total $70 million. This includes approximately $25 million for capitalized waste stripping, $15 million for TSF and water management systems, and $5 million for mine and mobile equipment.
  
  
• Eagle: Capital expenditures at Eagle in 2023 are forecast to total $20 million in 2023, composed of underground mine development, of which approximately $8 million is for development of the Upper Keel zone, and for mine and mill sustaining initiatives.
  
  
• Neves-Corvo: Capital expenditures at Neves-Corvo in 2023 are estimated to total $130 million in 2023. Approximately $50 million is forecast for underground mine development, including infill drilling, $60 million for projects to enable ZEP to consistently achieve nameplate capacity, and $10 million for mine and mobile equipment. Projects to enable ZEP to consistently achieve its 2.5 Mtpa processing capacity include raise and chiller additions to increase capacity of the ventilation system, installation of a redundant SAG feeder, expansion of the TSF, and process water treatment plant works.
  
  
• Zinkgruvan: Capital expenditures at Zinkgruvan are forecast to total $70 million in 2023, of which approximately $35 million is for underground development, including development of the Dalby orebody. Expenditure on the sequential flotation project, to improve concentrate grades and metal recovery rates, is forecast to be $8 million. The remainder of the sustaining capital expenditure is primarily for TSF works, reduced emissions and energy saving programs and other improvement initiatives.
  
  
• Josemaria Project: Capital expenditures are estimated to be approximately $400 million in 2023 in support of advancing the project prior to a potential construction decision. An updated initial capital cost estimate and project schedule review are progressing well with the updated Technical Report on-track for publication in the second half of 2023. Capital expenditures primarily include continuation of detail engineering, procurement of long-lead equipment, and preconstruction activities such as road upgrades and geotechnical work.

Exploration expenditures are planned to be $45 million in 2023 primarily for in-mine and near-mine targets at our operations. The largest portion of the planned expenditure is to be at Candelaria and Chapada with the remaining operations and new business development activities comprising the balance.
