Lundin Mining Third Quarter 2023 Results

VANCOUVER, Nov. 1, 2023 - (TSX: LUN) (Nasdaq Stockholm: LUMI) Lundin Mining Corp. ("Lundin Mining" or the "Company") today reported its third quarter 2023 financial results.

"Our operations continued with a strong performance in the third quarter. As a result, we are increasing our production guidance for Caserones and Eagle. The acquisition of Caserones enabled us to achieve a new record in quarterly consolidated copper production, and we also achieved a record in quarterly zinc production. This led the Company to an adjusted EBITDA of $415 million for the period." commented Peter Rockandel, CEO.

Mr. Rockandel added, "During the integration process of Caserones, our team has identified and outlined synergies between Caserones and Candelaria, which are expected to yield initial annual savings of $20 to $30 million per year. We are excited about launching the largest exploration program at Caserones since production commenced, targeting resource extensions and near-mine discoveries. The corporate office move to Vancouver is complete and all senior executive positions are in place. As we approach 2024, Lundin Mining is strategically, operationally, and financially, in a strong position to continue to deliver on our plans and execute on the next phase of growth. On a personal note, as this is my last quarter as CEO, I would like to thank all our employees, partners and stakeholders for their dedication, hard work and support, all of which have been integral to our current and future success. I am extremely proud of what the team has been able to accomplish during my tenure as CEO."

• Free cash flow of $71.1 million was $234.3 million higher than the prior year comparable period and benefited from the inclusion of production from Caserones, combined with higher realized copper prices and higher overall changes in working capital.

Outlook

Production and cash cost guidance for 2023 is updated from that disclosed in the Company's Management's Discussion and Analysis for the three and six months ended June 30, 2023.

Most production guidance ranges are tightening and improving, with the lower end of the range increasing for copper, nickel and gold. Cash cost guidance is lower for Caserones and Eagle driven by higher production volumes and by-product credits, and increasing for Candelaria, reflecting higher operating costs. Production continues to be weighted to the second half of the year, notably at Chapada due to the first half seasonal operating conditions and forecast grade and recovery profiles.

2023 Production and Cash Cost Guidance

As a result of re-phasing several projects at Neves-Corvo and Zinkgruvan, capital expenditure guidance is lower by an additional $30 million for 2023. As disclosed in the Company's Management's Discussion and Analysis for the three and six months ended June 30, 2023, capital spend guidance at Josemaria was previously lowered to $350 million for 2023 due to foreign exchange, a delay in planned equipment deliveries and reduced activities.

2023 Capital Expenditure

2023 Exploration Investment Guidance

Total exploration expenditures are on target to be $45.0 million in 2023, unchanged from previous guidance.

Operational Performance

Total Production

Candelaria (80% owned): Candelaria produced 34,275 tonnes of copper and approximately 20,000 ounces of gold in concentrate on a 100% basis in the quarter. Copper production was lower than the prior year quarter primarily due to lower grades partially offset by higher throughput. Gold production was lower than the prior year quarter due to lower grades and recoveries. Current quarter production costs and copper cash cost of $2.19/lb were higher than the prior year quarter largely owing to higher contractor and maintenance costs and unfavorable foreign exchange. Cash cost was further impacted by lower sales volumes.

Caserones (51% owned): In the three months ended September 30, 2023 Caserones produced 34,427 tonnes of copper and 1,321 tonnes of molybdenum on a 100% basis, of which 29,821 tonnes of copper and 1,096 tonnes of molybdenum were produced from the acquisition closing date of July 13. Copper and molybdenum production were higher than planned due to increased throughput and recoveries. Production costs in the quarter were negatively impacted by the recognition of fair market value adjustments to inventory due to the acquisition. Copper cash cost of $1.60/lb benefited from higher than planned production and by-product credits.

Chapada (100% owned): Chapada produced 12,286 tonnes of copper and approximately 15,000 ounces of gold in concentrate in the quarter. Copper and gold production was lower than the prior year quarter primarily due to lower throughput and grades. Production costs were lower than the prior year quarter due to lower sales volumes. Copper cash cost of $2.28/lb for the quarter increased from the prior year quarter due to lower sales volumes, unfavorable foreign exchange variances, and lower by-product credits and production.

Eagle (100% owned): During the quarter Eagle produced 4,290 tonnes of nickel and 3,245 tonnes of copper which were lower than the prior year quarter due to lower planned grades. Production costs were higher than the comparable prior year quarter due to inflationary contractual cost increases. Nickel cash cost in the quarter of $2.07/lb was higher than the prior year quarter primarily due to lower by-product credits and higher production costs.

Neves-Corvo (100% owned): Neves-Corvo produced 9,016 tonnes of copper and 25,807 tonnes of zinc in the quarter. Copper production was higher than in the prior year quarter due to higher throughput, grades and recoveries. Zinc production was higher than in the prior year quarter primarily due to increased grades and recoveries driven by the Zinc Expansion Project ("ZEP"). Production costs during the quarter were lower than the prior year quarter despite higher sales, primarily due to reduced electricity costs. Current quarter copper cash cost per pound of $2.27/lb was lower than the prior year quarter primarily as a result of lower input costs and benefited from higher production and sales.

Zinkgruvan (100% owned): Zinc production of 23,967 tonnes and lead production of 8,643 tonnes were higher than the prior year quarter primarily due to higher throughput and grades. Copper production of 1,299 tonnes was lower than the prior year quarter due to lower throughput. Production costs were higher than the prior year quarter primarily due to higher sales volumes. Zinc cash cost per pound of $0.28/lb during the quarter was higher than the prior year quarter primarily as a result of lower by-product costs per pound and higher treatment and refining charges.
