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.

Future

Advancement of innovative technologies focusing on reducing diamond damage

Long term mine planning and optimisation

Assessing external growth opportunities

The Letšeng mining lease was successfully renewed in 2019 and implemented in 2020
Developed key relationships with stakeholders in order to mitigate the impact of political in-country instability at the operations
The sale of Ghaghoo was significantly delayed during the year due to the impact of COVID-19
New partners were identified to advance the pilot processing plant to detect diamonds within kimberlite and further enhancement and testing will continue in 2021
