JOHANNESBURG (miningweekly.com) – Australia-based miner Lucapa Diamond Company is starting the year off on a high note, announcing on Wednesday that it had recovered another 100-ct plus stone at its Lulo project, in Angola.
The 116 ct low-quality diamond is the second 100-ct-plus stone recovered in the first three weeks of the year, and also the tenth such diamond unearthed at the mine, which Lucapa owns in a partnership with Empresa Nacional de Diamantes and Rosas & Petalas.
AdvertisementThe 116-ct stone was recovered through the X-ray transmission large-diamond recovery circuit installed at Lulo in late 2016.
“Though a low-quality stone, the diamond continues to underline the special large-stone nature and potential of the Lulo diamond project,” the company noted.

Meanwhile, the miner said it was encouraged by its Lesotho neighbour Letšeng Diamonds’ recent recovery of a 910-ct diamond, which is the fifth largest gem-quality diamond ever found.
The Letšeng mine is located within 5 km of Lucapa’s 70%-owned Mothae kimberlite mine, which previous trial mining has shown to be a source of large and premium-value diamonds.
Mothae remains on track for commissioning in the second half of the year, delivering Lucapa a second complementary high-value production source to Lulo.
