Manicaland Province Marange Fields have been known to be some of the largest source of diamonds in the world in the past few years. In 2015, Zimbabwe’s diamond production is expected to drop from 5.9 Million CTS to 3.5 Million.
Three new mines started operations last year in the Marange Fields, however, the increase in supply has not been steady, as these mining operations are expected to have a lesser impact, due to the fact that these are not alluvial mines.
Zimbabwe had a tremendous supply of alluvial diamonds, however, these alluvial diamonds have been mined extensively, and alluvial supply is running short. Therefore minors now have to dig for rough stones underground instead, making it more difficult and more expensive to mine for rough diamonds.
This is the number one reason for the decrease in production in the Marange Fields. In order to optimize the management and production of these mines, the Government is in the process of merging five mining companies into one large corporation.
