Currently, MCM mines between 3.5 and 4.0 million tpa (tonnes per annum) of ore from its four underground mines. Due to depleting ore reserves in the Central Shaft and Mindola North Shaft, it is projected that the total amount of ore to be mined from the SOB and Mindola Main shafts will be 1.8 million tpa by 2015.
Figures 4-1 and 4-2 show the 10 years projection of Nkana Copper ore and contained copper production respectively. Nkana mine currently produces about 3.5 million tpa of ore (approximately 65 thousand tons of contained copper). It is projected that ore production will drop to approximately below 1.5 million tpa of ore (30 thousand tonnes of contained copper) by 2015 without the implementation of the Synclinorium project. It is also projected that contained copper production will increase to 5.0 million tpa of ore (or 100 thousand tonnes of contained copper) by 2018 with the implementation of the Synclinorium project.
