Lundin Mining Fourth Quarter and Full Year 2023 Results

VANCOUVER, Feb. 21, 2024 - (TSX: LUN) (Nasdaq Stockholm: LUMI) Lundin Mining Corp. ("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."

Summary Financial Results

• For the year ended December 31, 2023 the Company generated revenue of $3,392.1 million (2022 - $3,041.2 million), gross profit of $652.4 million (2022 - $762.6 million) and adjusted EBITDA of $1,363.5 million (2022 - $1,292.5 million).

• Net earnings attributable to shareholders of the Company were $38.8 million ($0.05 per share) in the fourth quarter, and were impacted by higher interest expenses and increased deferred tax on foreign exchange revaluation of non-monetary assets at the Josemaria Project in Argentina.

• Adjusted earnings¹ attributable to shareholders of the Company for the twelve months ended December 31, 2023 of $336.2 million ($0.44 per share) were $146.6 million lower than the prior year after adjusting for the non-cash revaluation of derivative contracts, fair value adjustments relating to the Caserones acquisition and deferred tax relating to foreign exchange translation and a Chilean mining royalty rate change, among other things.
• Cash and cash equivalents as at December 31, 2023 were $268.8 million. Cash provided by operating activities of $1,016.6 million in the year ended December 31, 2023 was used to fund investing activities of $1,674.5 million.

Cash generated from financing activities was $728.6 million, which was comprised primarily of the proceeds from the Term Loan to finance the Caserones acquisition.
• Free cash flow¹ for the three months ended December 31, 2023 of $61.2 million was $185.5 million higher than the prior year comparable period and benefited from the inclusion of Caserones cash flows as well as higher gross profit overall at the operations.

Operational Performance

Total Production

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.

2024 Production and Cash Cost Guidance

2024 Capital Expenditure Guidance^a,b

2024 Exploration Investment Guidance

Total exploration expenditure guidance for 2024 is $48.0 million.

Exploration: Exploration drilling campaigns are underway at Caserones, Josemaria, Chapada and Zinkgruvan. Drilling at Caserones is targeting the Angelica target and Caserones sulphide deep target with three rigs. Initial holes are underway at Josemaria's Cumbre Verde target, and additional roads are being developed to gain access to higher priority areas. At Chapada, drilling is focused on higher grade corridors within known areas of mineralization that could contribute higher grades to the mine plan. At Zinkgruvan, drilling with six rigs is focused on extending multiple deposits, with the priority on the high-grade Borta Barkom area.
