NEWS RELEASE

Lundin Mining Pre-Announces Items Impacting the Fourth Quarter 2023 Results

Vancouver, January 29, 2024 (TSX : LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin

Mining” or the “Company”) is pre-announcing certain items impacting the Company’s quarterly earnings, adjusted

earnings before interest, taxes, depreciation and amortization (“adjusted EBITDA”) 1, adjusted earnings 1 and

adjusted earnings per share1.

Foreign Exchange and Derivatives

Items of significant impact in the fourth quarter 2023 are expected to include unaudited foreign exchange and

trading gains on debt and equity investments supporting the capital funding for the Josemaria Project of

approximately $19 million on a pre -tax basis and unaudited realized gains on foreign exchange and diesel

derivative contracts of approximately $9 million on a pre-tax basis.

In the fourth quarter 2023 the Company is also expected to recognize an unaudited non-cash unrealized gain of

approximately $19 million on a pre-tax basis related to the mark-to-market valuation of the Company’s unexpired

foreign exchange and diesel derivative contracts. This non-cash gain will impact the Company’s earnings but not

adjusted EBITDA, adjusted earnings or adjusted earnings per share.

Provisional Pricing Adjustments

Revenue in the fourth quarter 2023 is expected to be negatively impacted by decreases in metal prices for

molybdenum and nickel during the quarter. The sales volume during the quarter for molybdenum and nickel was

978 tonnes and 3,105 tonnes, respectively . Downward provisional pricing adjustments on concentrate sales

completed in prior quarters is expected to reduce revenue in the fourth quarter by approximately $5/lb for

molybdenum and approximately $1/lb for nickel. Downward provisional pricing adjustments on concentrate sales

completed in prior quarters relating to other metals are not expected to be significant.

The report for the year ended December 31, 2023, will be published on Wednesday, February 21, 2024.

under International Financial Reporting Standards and, therefore, amounts presented may not be comparable to simil ar data presented by other mining
