MOTHAE KIMBERLITE MINE
Mothae is located in Lesotho’s diamond-rich Maluti Mountains within 5km of Letseng, the world’s highest US$ per carat kimberlite diamond mine.
Mothae is a well-defined kimberlite pipe with a surface area of ~8.8 hectares. The pipe has a JORC classified diamond resource of +1 million carats (to a depth of 300m) at an average modelled diamond value of US$1,063 per carat (Refer ASX announcement 24 March 2017).
Lucapa completed construction of the new 1.1Mtpa Mothae diamond plant and commenced commercial diamond recoveries in Q4 2018, complementing the high-value production from the Lulo mine in Angola.
Initial recoveries have included D-colour white diamonds weighing 78 carats and 38 carats.
The first sale of commercial diamonds from Mothae is scheduled for Q1 2019.
The new Mothae plant incorporates advanced diamond recovery technology, including two XRT diamond recovery modules designed to recover large and rare Type IIa diamonds ahead of the secondary crushing circuit, thus reducing potential diamond breakage and improving the recovery of unbroken large stones.
Production from Mothae is scheduled to double to 2.2Mtpa in 2021 under Phase 2 of the development plan.
