Kagem Mining Limited engages in the exploration, mining, processing, and sale of emeralds. The company was founded in 1985 and is based in Kitwe, Zambia. Kagem Mining Limited operates as a subsidiary of Gemfields Plc.
The Kagem emerald mine is the world’s single largest producer of emeralds and accounts for approximately 20% of global emerald production. The mine covers an area of approximately 41 square kilometres and is located in the central part of the Ndola Rural Emerald Restricted Area (“NRERA”), in the Copperbelt Province of Zambia.
Kagem is an open-pit emerald mine. The operation currently runs to as much as 130 metres in depth (imagine the height of an +40 storied office block), is 1.5KM in length and approximately 750 metres wide.
However, we aren’t just digging and leaving big craters, instead with a mining & back filling strategy, the open pit is slowly migrating across the landscape with the footwall constantly being in-filled. We are putting back the hard rock in the exhausted areas of ore mining within the pit, the top soil is utilized on top of the in-active waste dump to create an environment that is suitable for revegetation of the land.
