Our strategy

HOW WE CREATE VALUE

(Tap a section below for more information)

Mining

Letšeng

Letšeng, our core diamond mine, is the highest achieving average US$ per carat kimberlite mine in the world. The operation is an open pit diamond mine with two kimberlite pipes, the Main pipe and the Satellite pipe which are 17.0 and 5.2 hectares respectively.

Processing

At Letšeng, ore is processed through three treatment plants with an annual throughput of 6.4 million to 6.6 million tonnes. Although Letšeng’s grade recovery is low (averaging just under two carats per hundred tonnes) it is famous for producing large, high-value diamonds.

Sales,
marketing and
manufacturing

Our diamonds produced are predominantly sold through a tender process by our sales and marketing operation in Antwerp, Belgium. Through mapping and analysis, the value of the Letšeng high-quality diamonds is determined and used to achieve the highest rough value through multiple selling channels. A selection of high-value diamonds are manufactured to capture additional value through polished sales.


Our strategy is underpinned by three key priorities which we believe will deliver maximum value for all stakeholders through our business cycle.
