Technology and innovation
Diamond damage is ubiquitous among producers of larger high-value gem diamonds. Furthermore, the Letšeng mine has a unique diamond distribution with a significant portion of its revenue held in the +5mm fraction (greater than two carats).
The Group has been working to mitigate the impact of diamond damage on Letšeng’s production for many years. While incremental improvements have been achieved through optimising operating practices and various technological enhancements, tweaking conventional technology will not realise the step changes required to significantly reduce diamond damage.
The potential changes for significantly improving revenue through reducing diamond damage are:
- the early identification of liberated diamonds;
- identification of diamonds within kimberlite; and
- a non-mechanical means of liberating these diamonds within kimberlite.
Gem Diamonds has made significant progress on the identification, validation and testing of technologies from various industries to complement its innovation drive of early detection and non-mechanical means of liberating diamonds.
