The Katanga, or Shaba, copper belt in the DRC is a belt about 70 kilometres (43 mi) wide and 250 kilometres (160 mi) long between Lubumbashi and Kolwezi formed in rocks of the Katanga Supergroup. There are 72 economic deposits of copper/cobalt and four large mining centers. Taken together, the DRC and Zambian copper belts are the second largest global reserve of copper, about 1/3 the size of the Chilean reserve.
The DRC copper belt includes some of the highest-grade copper deposits in the world. In some reserves the grades are above 5%. The ore also has high grades of cobalt and may hold 34% of the world’s cobalt reserves. There are large deposits that have yet to be explored using modern technology, so the size of the reserves may be understated. Demand is growing, led by China.
