Kariba Amethyst
Mine, Zambia

Overview

The Kariba amethyst mine covers an area of 396 hectares, and is located in the southern part of Kalomo district, Zambia (approximately 550 kilometres south- southwest from the Kagem emerald mine). Kariba has produced some of the finest amethyst in the world.

Its unparalleled deep purple hue, combined with exceptional lustre, sets the standard for excellence internationally. Kariba’s market share has been estimated at over 90% of the amethyst originating from Zambia with annual production reaching as much as 800 tonnes per annum, making it one the largest producers of amethyst in the world. Kariba has, over the years, developed a bespoke amethyst grading system that has established its gemstones as premium products.

Kariba Amethyst Mine

Geology

Open-Pit Mining

Three major zones of amethyst mineralisation have been identified within the licence.

Two of these are located in the central area and host the mine’s most significant amethyst deposits. These zones run through the Cha Cha, Francis, Curlew, Davidson and Horden prospects.

Safety

The size of the Kariba operation, which in comparison to Kagem and Montepuez is very small, does not mean that the approach to health, safety and environment is any less robust.

The integrity of Kariba’s approach is still rigorous and the operation has in place the necessary processes to manage the risks according to the likelihood, severity and size of the operation. Kariba’s management gives its staff access to a local doctor for hospital referrals and works with health delivery partners to carry out health and safety training. Environmental studies have been carried out in accordance with law and these approaches are integrated into the mine operations and rehabilitation plan.
