The mining sector is expected to make up half of the Democratic Republic of the Congo's gross domestic product (GDP) over the next five years, according to officials.
Mines Minister Martin Kabwelulu said the contribution of the mining sector to the state's budget will increase to 50% of GDP by 2015. At present, it represents 23-25% of GDP, reports Reuters.
The country's GDP for 2009 stood at $10.8bn, according to the World Bank.
Earlier this year, the Democratic Republic of the Congo predicted that it would double copper and cobalt production by 2012 and increase copper output to nearly two million tons per year by 2015.
The country’s total copper output in the first nine months of 2010 has totalled 350,000t, exceeding the full-year production of 309,610t in 2009.
The country's cobalt output to September stood at 67,000t, surpassing the 56,103t produced during the whole of last year.
