Mothae Development Plan
The high-quality kimberlite diamond production from Mothae will complement that from the Lulo alluvial mining operations in Angola, giving Lucapa two high-value producing assets.
Under the two-Phase Mothae development plan, production is scheduled to double to 2.2Mtpa in 2021 under Phase 2.
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
In parallel with the construction of the new 1.1Mtpa diamond plant and infrastructure, Lucapa has been conducting a bulk sampling campaign at Mothae.
More than 4,100 carats of diamonds have been recovered from bulk sampling sections of the Mothae kimberlite pipe which had not previously been tested (and thus not included in the Mothae JORC resource), or had been inadequately tested during the previous trial mining phase.
Bulk sampling recoveries to date have included yellows weighing 89 carats and 25 carats and white diamonds of up to 28 carats
