Lucapa Diamond Company and its partner, the Government of the Kingdom of Lesotho, announces an updated JORC classified Indicated and Inferred Diamond Resource estimate for the Mothae kimberlite diamond mine in Lesotho, southern Africa.
A total JORC classified Indicated Resource has been estimated for 9.2 million tonnes (“Mt”), containing ~280,000 carats of diamonds at a diamond grade of 3.10 carats per one hundred tonnes and an average un-escalated modelled diamond value of US$635 per carat.
This Indicated Resource has been estimated to 75m depth below the current pit floor in the South Lobe at a nominal 3mm bottom cut-off size. In addition, a total JORC classified Inferred Resource has been estimated for 39.4Mt, containing ~960,000 carats of diamonds at a diamond grade of 2.44 cpht and an average un-escalated modelled diamond value of US$601 per carat. This Inferred Resource has been estimated from below the Indicated Resource to 300m below surface, at a nominal 3mm BCOS.
Lucapa Managing Director Stephen Wetherall commented “The updated Mothae Resource is the result of significant work undertaken to increase the resource and classification at Mothae following almost 16 months of mining and treatment through the new commercial plant.” “The increase in tonnes and carats, the classification of 9.2Mt or ~280,000 carats into indicated resource category at an estimated diamond value of US$635 per carat strongly supports an expansion in production at Mothae that the partners are considering.”
