07:41 AM EDT, 07/18/2025 (MT Newswires) -- Lundin Mining ( LUNMF ) reported overnight Thursday certain items impacting its earnings for the second quarter.

The miner expects its revenue to be negatively impacted by provisional pricing adjustments on prior period concentrate sales of about US$6 million on a pre-tax basis. These adjustments primarily include downward adjustments in relation to prior period copper sales, partially offset by upward adjustments on prior period gold sales.

Lundin also expects to recognize certain non-cash items including an unrealized gain of about US$11 million on a pre-tax basis. This is related to the mark-to-market valuation of the company's unexpired foreign exchange and commodity derivative contracts.

Lundin will release its second-quarter operational and financial results after market close on Aug. 6.
