This is the Chimiwungo Pit of the Lumwana copper mine and as of 3rd quarter 2014 the imagery was still not new enough to show the pit. The Chimiwungo ore body is 95% sulphide, 5% oxide, and very consistent so conventional truck and shovel method is used. Chimiwungo is larger and lower in copper grade than Malundwe, but has higher overall cobalt and contains a number of significant high-grade (>0.1%) cobalt zones plus some sporadic uranium mineralisation. The ultimate Chimiwungo Main pit will measure approximately 1.7 km east to west, 3.7 km north to south, and have an average depth of approximately 350 m.

The Chimiwungo deposit is partitioned into three bodies by two steep west-northwest trending dip-slip fault zones. The mineralized zones are referred to as Chimiwungo South, Chimiwungo Main (includes the recently discovered Chimiwungo East mineralized shoot), and Chimiwungo North. The mineralization Chimiwungo currently extends up to 1.5 km north-south and 2.8 km in the east-west orientation and remains open to the east and south.
