NEWS RELEASE

Lundin Mining Provides Update on Labour Action at Candelaria

Toronto, October 18, 2020 (TSX: LUN; Nasdaq Stockholm: LUMI) Lundin Mining Corporation (“Lundin

Mining” or the “Company”) announced today that despite mediation with the Candelaria AOS Union (the “Union”),

which represents approximately 550 workers at its Candelaria operations in Chile , the Company and the Union

have failed to reach an agreement. The Union can legally be on strike commencing October 20, 2020. The

Candelaria Mine Workers Union continues with its labour action which commenced on October 8, 2020.

Lundin Mining holds health and safety as a top priority in everything we do. Illegal and violent actions promoted

under the guise of the legal strike of the Mine Workers Union, and the pending labour action of the Candelaria

AOS Union, puts the safety of our Candelaria workforce at risk. Candelaria operations are currently in the process

of planning for temporary suspension. Critical works will continue to be executed to protect required onsite

personnel, the operation and the environment. The Company sincerely regrets having to take this action and its

impact on our workforce, local community, suppliers, customers and many stakeholders.

Previously provided 2020 production, cash cost and capital cost guidance for Candelaria , should no longer be

relied upon. Lundin Mining is in strong financial position with a net debt position of approximately $124 million,

including cash and equivalents of approximately $222 million, and available credit of approximately $575 million

under its revolving credit facility, as at September 30, 2020.

Candelaria is committed to responsible, respectful, and fair negotiations with the best interests of our workers

and the sustainability of our business in mind. The previous collective agreement with the Candelaria AOS Union

expired on October 5, 2020, after the Union was granted a special extension of the agreement by the L abour

Authority which was set to expire on September 30, 2020. Candelaria and the Union subsequently entered into

a mediation process in which multiple improved offers were presented to the Union leadership.

Lundin Mining will issue further statements as appropriate.
