The Serbia Zijin Copper company, operator of Serbia's sole copper complex, plans to invest $408-million in 2021, up from $360-million in 2020, to overhaul and expand its four mines and a smelter, it said on Wednesday.
The plan also includes improving environmental protection in the heavily polluted Bor region, in Serbia's east, it said in a statement posted on its website.
The company, part of China's Zijin Mining, said it planned to boost output of copper concentrate by 38.91% to 74 010 tonnes and cathode copper by 18% to 83 450 tonnes this year.
In 2018, Zijin Mining became Serbia's strategic partner in the copper complex RTB Bor, pledging to invest $1.26-billion in return for a 63% stake.
In its statement, the company also said it aimed to produce 2.5 tonnes of gold and 10 tonnes of silver in 2021, an annual increase of 45.14% and 10.12% respectively.
China has invested billions of euros in Serbia, mostly in the form of soft loans to finance highway and energy projects, as part of its so-called belt and road initiative to open new foreign trade links.
