Lundin Mining Pre-Announces Items Impacting the Third Quarter 2025 Results
Revenue in the third quarter 2025 is expected to be positively impacted by unaudited provisional pricing adjustments on prior period concentrate sales of approximately $11 million on a pre-tax basis. These adjustments primarily include upward adjustments in relation to prior period copper and gold sales.
Revenue in the third quarter 2025 is also expected to be impacted by a timing difference between the production and shipment dates of approximately 20,000 tonnes of copper concentrate (approximately 5,100 tonnes of contained payable copper). A shipment of copper concentrate from Caserones scheduled for September was delayed into October due to weather related issues. The related revenue and cost of goods sold are expected to be recorded in the fourth quarter 2025.
Unaudited realized foreign exchange gains and unaudited realized losses on derivative contracts in the third quarter 2025 are not expected to be significant.
In the third quarter 2025 the Company is expected to recognize certain non-cash items that will impact the Company's earnings but not adjusted EBITDA, adjusted earnings or adjusted earnings per share. These include an unaudited unrealized loss of approximately $26 million on a pre-tax basis related to the mark-to-market valuation of the Company's unexpired derivative contracts, primarily due to rising gold prices during the quarter. Unaudited unrealized foreign exchange gains are not expected to be significant.
