Mothae Development Plan

Lucapa and the Government of the Kingdom of Lesotho are on track to commence commercial diamond production at Mothae in H2 2018, with construction of the new 1.1 million tonne per annum plant and infrastructure proceeding on schedule.

The kimberlite diamond production from Mothae will complement that from the Lulo alluvial mining operations in Angola, giving Lucapa two high-value producing assets.

In October 2017, Lucapa announced an updated mine development plan for Mothae with a range of improvements including:

  • A 29% increase in gross project revenues to US$776m
  • A 26% increase in net operating cash flows to US$312m
  • A 22% increase in diamond production to ~500,000 carats
  • A 12% increase in mine life to 13.5 years

The Mothae mine plan includes plans to double production to 2.2 million tonnes per annum in 2021 under the Phase 2 development.

Lucapa plans to further update the mine plan ahead of commercial production. This update will incorporate a range of factors including project de-risking, favourable exchange rate movements and the results of geotechnical studies.

In parallel with the construction of the new 1.1 million tonne per annum plant, Lucapa has been conducting a bulk sampling program at Mothae with the aim of expanding the current JORC diamond resource by testing areas of the kimberlite pipe either not included in the resource or which require further sampling.

This bulk sampling program has already achieved highly-encouraging results, including an 89 carat yellow diamond recovered from the South-East zone of the kimberlite pipe, a 25 carat yellow diamond from the Neck zone and Specials weighing 28 carats and 12 carats from the North zone, along with two small light pink diamonds.
