NEWS RELEASE

Lundin Mining Fourth Quarter and Full Year 2023 Results

Vancouver, February 21, 2024 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin Mining” or the “Company”) today reported its fourth quarter and full year 2023 financial results. Unless stated otherwise, results are presented on a 100% basis and Caserones results are from July 13, 2023.

Jack Lundin, President and CEO commented, "2023 was a milestone year for the Company. We finished the year generating a record $3.4 billion in revenues and achieved our best-ever quarterly and full year copper production which we forecast to further increase by over 15% in 2024. Our 2023 financial performance was strong with $1.4 billion in adjusted EBITDA1, $345 million in free cash flow from operations1 and we returned $206 million to our shareholders in dividends.

“The Company’s record copper production was driven by our strategic acquisition of a majority interest in Chile’s Caserones copper mine, as well as organically through our expansion project at Neves-Corvo, which also contributed to record fourth quarter zinc production for the Company. Going forward, we will be disciplined in our growth plans and capital allocation as we continue to optimize assets and operational efficiencies to drive down costs.

“At Josemaria, we're derisking the project via optimization and trade-off studies that aim to enhance the overall value of the Project. We are concurrently continuing to explore potential partnership opportunities and actively working towards establishing stability agreements in Argentina.”

Fourth Quarter Highlights

  • Copper Production: Consolidated production of 103,337 tonnes of copper in the fourth quarter, a quarterly record for the Company and an increase of over 80% on the same quarter in the previous year.
  • Other Production: During the quarter, a total of 50,719 tonnes of zinc, 3,729 tonnes of nickel and approximately 44,000 ounces of gold were produced. The zinc expansion project ("ZEP") at Neves-Corvo contributed to record quarterly zinc volumes being produced.
  • Revenue: $1,060.0 million in the fourth quarter.
  • Adjusted EBITDA1: $419.7 million generated during the quarter.
  • Adjusted Earnings1: Net earnings attributable to shareholders of the Company were $38.8 million ($0.05 per share) in the fourth quarter with adjusted earnings of $79.7 million ($0.10 per share).

a. Tonnes (t) and thousands of ounces (koz)

b. Candelaria and Caserones production is on a 100% basis. Caserones results are from July 13, 2023.

Candelaria (80% owned): Candelaria produced, on a 100% basis, 152,012 tonnes of copper, approximately 90,000 ounces of gold and 1.5 million ounces of silver in concentrate during the year. Copper production was consistent with the prior year due to higher throughput being offset by lower grades and recoveries. Gold production was higher than in the prior year due to higher throughput and grades. Both metals were within the most recently disclosed 2023 production guidance ranges. Total production costs were higher than the prior year primarily due to inflationary cost increases and unfavourable foreign exchange. Copper cash cost1 of $2.07/lb was within the most recently disclosed 2023 cash cost guidance range.

Caserones (51% owned): Caserones produced 65,210 tonnes of copper and 2,024 tonnes of molybdenum on a 100% basis during the year, from the acquisition closing date of July 13, 2023 to the end of the year. Both metals met or exceeded the most recently disclosed 2023 production guidance ranges due to strong throughput, grade and recoveries. Copper cash cost of $1.99/lb was slightly below the low end of the most recently disclosed cash cost guidance range as a result of higher production.

Chapada (100% owned): Chapada produced 45,719 tonnes of copper and approximately 59,000 ounces of gold, with copper production remaining consistent to the prior year and gold production being negatively impacted by lower grade, throughput, and recoveries. Both metals were within the most recently disclosed 2023 production guidance ranges. Total production costs were lower than the prior year due to lower sales volumes. Full year copper cash cost of $2.27/lb was below the low end of the most recently disclosed cash cost guidance.

Eagle (100% owned): Eagle’s production of 16,429 tonnes of nickel and 13,600 tonnes of copper were near the higher ends of recently disclosed 2023 production guidance ranges but lower than that in the prior year due to planned lower grades. Total production costs were lower than the prior year due to lower sales volumes. Nickel cash cost1 of $2.16/lb was within the most recently disclosed 2023 cash cost guidance range but higher than the prior year as a result of lower grade, lower by-product credits and higher repair and maintenance costs.

Neves-Corvo (100% owned): Neves-Corvo produced 33,823 tonnes of copper and 108,812 tonnes of zinc during the year. Zinc production increased significantly from the prior year due to higher throughput as a result of the zinc expansion project ("ZEP"). Copper production also increased due to higher throughput and production of both metals was within the most recently disclosed 2023 production guidance ranges. Total production costs were lower than in the prior year despite higher sales, primarily due to lower input costs, in particular lower electricity and diesel prices, partially offset by unfavourable foreign exchange. Copper cash cost1 of $2.37/lb for the year exceeded the most recently disclosed 2023 cash cost guidance range and was higher than in the prior year primarily due to lower zinc by-product credits, higher treatment and refining charges, and unfavourable foreign exchange.

Zinkgruvan (100% owned): Zinc production of 76,349 tonnes was consistent with the prior year, but slightly below the most recently disclosed 2023 production guidance range. Installation of a sequential flotation system during the year achieved improved recoveries, but a longer than anticipated ramp-up limited mill availability and reduced recoveries, limiting production of both lead and zinc. Lead production of 26,284 tonnes was also lower than in the prior year. Total production costs and sales volumes were consistent with the prior year and zinc cash cost1 of $0.43/lb was below the most recently disclosed 2023 cash cost guidance range but higher than in the prior year, primarily due to lower by-product credits.

Outlook

Production, cash cost, capital expenditures and exploration investment guidance for 2024 remains unchanged from the most recently reported guidance as outlined in the news release 'Lundin Mining Provides 2024 Guidance & Announces 2023 Production Results" dated January 14, 2024.
