Summary:
Mining operations currently exploit the steeply dipping ore bodies by conventional underground mining methods that are accessed via two vertical shafts, the No. 1 and the No. 2 shaft that provide access to a maximum depth of 300 metres below the surface. The mining method employed at the Nampundwe mine is conventional sub level open stoping with fan drilling.
Summary:
RoM ore from underground is hoisted directly onto the concentrator shaft bin for primary crushing before it is conveyed through the 120-tonnes/hour belt for secondary crushing.
The concentrator comprises conventional crushing-flotation-filtration circuits.
Nampundwe exploits iron pyrite rich ore bodies containing 11.0% in situ sulphur and has capacity to produce 60,000 tpa of pyrite concentrate that is blended with copper concentrate for smelting.
