MOTHAE KIMBERLITE MINE
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 commercial production to commence in January 2019.
Results to date have confirmed that like Lulo, Mothae is also a source of large and premium-value diamonds, including rare Type IIa whites and coloured gems ( View Gallery ).
Large diamond recoveries to date have included 4 +100 carat stones, including a 101 carat D-colour Type IIa.
Sales revenues to date total US$26.6 million (A$38 million). Individual Mothae diamonds have sold for up to US$36,000 per carat.
While kimberlite material was sourced predominantly from lower-margin zones of the 8.8 hectare kimberlite pipe in H1 2019, mining has since transitioned to the higher-margin southern pit following dewatering into the main water dam.
Initial recoveries from the southern pit include two exceptional 101 carat and 64 carat D-colour Type IIa gems, the first two commercially produced diamonds from Mothae sold for a price exceeding US$1 million.
