RAPAPORT… Gem Diamonds has unearthed a 115-carat rough diamond, as
the company’s shift to a more lucrative part of its Letšeng mine continues to
yield an improvement in recoveries of large stones.
The D-color, type-IIa diamond is the sixth stone above
100 carats that Gem Diamonds has found this year at its high-value mine in
Lesotho. In 2016, the miner only recovered five diamonds of this size,
resulting in a 22% drop in revenue.
In the second quarter of this year, the company switched
focus to the higher-grade K6 portion of Letšeng’s main pipe, enabling a higher
recovery rate of large diamonds.
Letšeng Mine Yields 115ct. Diamond
The Bottom Line
- Gem Diamonds found a 115-carat rough diamond at Letšeng, a D-color, type-IIa stone.
- This is the sixth diamond over 100 carats recovered at Letšeng this year, surpassing last year's total of five.
- The company’s shift to mining the higher-grade K6 section in Q2 improved large diamond recovery rates.
