Lucapa owns 70% of the high-value Mothae kimberlite mine in partnership with the Government of the Kingdom of Lesotho (30%).

Mothae is located in Lesotho’s diamond-rich Maluti Mountains within 5km of Letseng, the world’s highest US$ per carat kimberlite diamond mine.

Lucapa completed construction and commissioning of a new 1.1 Mtpa Mothae diamond plant in 2018, enabling production to commence in January 2019.

Results to date have confirmed Mothae is a source of large and premium-value diamonds, even though mining has been restricted to the lower-margin zones of the kimberlite pipe until the main southern pit is dewatered in H2 2019.

Recoveries have included a 126 carat gem-quality diamond and five other +50 carat stones. Mothae has also produced fancy coloured gems and rare Type IIa whites.

Two tenders of Mothae diamonds completed to date in H1 2019 in Antwerp have achieved total sale proceeds of US$7.3 million. This represents an average price per carat of US$588 for run of mine production and US$729 for diamonds in the +11 sieve size fraction.
