[1] The mines were first worked by filling a wheelbarrow with the gem containing soil and then washing away the earth,[4] but were replaced by modern placer techniques.

In 2019, Kuvimba Mining House (KMH), which is 65% owned by the Zimbabwe government, took over the asset.

[6] Intruded into the greenstone are granitic pegmatites containing rare earth minerals such as spodumene.

These pegmatite were intruded just prior to and/or during a main deformation event at 2.6 Ga.(2.6 billion years ago).

[7] Subsequently, along the cracks between the pegmatites and the greenstone, a hydrothermal solution complex was injected containing large amounts of sodium, as well as lithium, fluorine, beryllium, phosphorus and chromium.
