The company said yesterday copper production was expected to increase 20% in 2020 compared with this year, zinc would increase 15% and nickel by 25%, as it released a three-year outlook.
Its copper guidance is further forecast to increase from 272,000-296,000 tonnes in 2020 to 292,000-316,000t in 2022.
Last year, the company had expected to produce 227,000-246,000t of copper in 2020.
Lundin said yesterday its three-year outlook had improved mainly on the inclusion of the Chapada copper-gold mine, the Brazil operation acquired from Yamana Gold earlier this year, and refining Candelaria's production profile in Chile.
In Portugal, the Neves-Corvo zinc expansion project was on schedule for a phased ramp-up in 2020, which was expected to help lift overall zinc production from 172,000-187,000t in 2020 to 224,000-234,000t in 2022.
Nickel guidance was set at 15,000-18,000t for the next three years with the increased level expected to hold due to higher-grade ore from Eagle East in the US.
Lundin's gold guidance reduced slightly over the period, from 190,000-200,000 ounces in 2020 to 180,000-190,000oz in 2022.
The company has forecast 2020 capex of US$620 million, with the major spend of $265 million at Candelaria which it said was a decrease "compared to the reinvestment years of 2018 and 2019".
It said $15 million remained to be spent next year on Candelaria's mill optimisation investment, which was on schedule for completion in the first quarter.
Some $155 million was earmarked for the zinc expansion project at Neves-Corvo and it said the preproduction capex estimate of $430 million remained unchanged.
Lundin expected to spend $65 million on exploration next year, with the bulk to be spent on in-mine and near-mine targets.
The company also intends to renew its normal course issuer bid, which could see it purchase then cancel up to 10% of its shares over the coming year.
Lundin shares are trading towards the upper end of their 52-week range of C$5.115-$7.96 but closed down 1.6% yesterday to $7.33.
It is capitalised about $5.4 billion (US$4 billion).
