Zambia plans to provide stable policies and a predictable tax regime to keep mine production in Africa's second-largest copper producer viable, its deputy finance minister said on Wednesday.

"We are engaging with the mines in terms of coming up with a consistent, predictable tax regime to ensure the mines remain viable," Christopher Mvunga told a mining conference in Cape Town.

Zambia has resumed issuing new mining licences, and granting renewal and transfer of rights which it had suspended in August last year, its mines minister has said.
