Lucapa finds over a hundred diamonds at Australian project

Brooking diamond update

Lucapa Diamond Company Limited (ASX: LOM) (“Lucapa” or “the Company”) and its partner, Leopold Diamond Company Pty Ltd, are pleased to provide the following update on the macro and micro diamonds recovered from the Little Spring Creek prospect at the Brooking diamond project in Western Australia’s West Kimberley region (Refer ASX announcement 11 January 2018).

Subsequent review of the cleaned diamonds illustrate a relatively high white diamond content with yellow diamonds also being noted. The Brooking diamond project (80% owned by Lucapa) is located within 50km of the Ellendale mine which, when in production, was the world’s leading source of fancy yellow diamonds.

As set out in the ASX announcement of 11 January 2018, a total of 119 diamonds were recovered from 86.8kg of samples from lamproite intersected in the core of a single HQ (63mm diameter) hole drilled at the Little Spring Creek prospect.

The 119 diamonds recovered from the Little Spring Creek lamp roite drill core samples included seven macro diamonds and 112 micro-diamonds. Macro-diamonds are classified as individual stones greater than 0.5mm in at least one dimension. Diamonds smaller than 0.5mm are classified as micro-diamonds.

The largest of the seven macro-diamonds recovered from the Little Spring Creek core samples was approximately 1.0mm x 0.6mm x 0.5mm in size.

The photos of the Little Spring Creek diamonds on page one of this announcement were taken with a microscope camera subsequent to the diamonds being cleaned.

As set out in the ASX announcement of 29 January 2018, Lucapa is planning follow-up exploration programs at Little Spring Creek and other prospective targets identified within the 118km2 Brooking project.

This work will commence as soon as access to the West Kimberley region is available again after the northern wet season.

For and on behalf of the Lucapa Board.

About Lucapa

Lucapa is a growing diamond company with a portfolio of high-quality production, development and exploration assets in Angola, Lesotho, Botswana and Australia. The Company’s focus on high-value diamond production is designed to protect cash flows in a sector of the diamond market where demand remains robust.

Lucapa’s flagship asset is the Lulo Diamond Project in Angola, which is a prolific producer of large and premium-value alluvial diamonds. Lulo has produced 10 +100ct diamonds to date and is the highest US$ per carat alluvial diamond production in the world. Lucapa and its Lulo partners continue to advance their search for the primary kimberlite source of these exceptional alluvial gems, with three drill rigs now available in the ongoing kimberlite exploration program.

In keeping with the Company’s growth strategy, Lucapa has acquired a 70% interest in the advanced Mothae kimberlite project in diamond-rich Lesotho. The Mothae kimberlite pipe is a high-quality diamond resource located within 5km of Letšeng, the highest US$ per carat kimberlite diamond mine in the world. Lucapa is constructing a 150 tonne per hour (90,000 tonnes per month) diamond treatment plant, complete with XRT recovery technology, under its Phase 1 development program and is scheduled to commence high-value production at Mothae in H2 2018. Bulk sampling will commence at Mothae in the March 2018 Quarter.

Lucapa is also advancing exploration programs at two other diamond projects – Brooking in the West Kimberley lamproite province in Western Australia, where the Company has recently discovered lamproite with high concentrations of micro and macro diamonds, and Orapa Area F in Botswana’s Orapa diamond field, where identified targets will be drilled in 2018.

Lucapa’s Board and management team have extensive diamond industry experience across the globe with companies including De Beers, Rio Tinto and Gem Diamonds. The Company was included in the ASX All Ordinaries Index in March 2017.
