The operation initiated an approvals process for the construction of new flotation landfill last year. In 2018 it invested €2.2m into its operations and expects to sink another €3m into new equipment and mining preparation works. The majority owner of mine is the UK Mineco Limited. Mineco, which manages across Serbia, is an international group that sells non-ferrous metals and ore concentrates with investments around the SEE countries and the former Soviet Union.
