Lulo Alluvial Diamond Mine, Angola
Project One

Lulo Alluvial
Mine

Lulo lies in Angola's diamond heartland of Lunda Norte, 630km east of the capital, Luanda. While the total Lulo concession spans a vast 3,000 km², the commercial alluvial mining licence covers a specific 1,500 km² area, representing one of the world's most prolific alluvial diamond fields and commanding the highest price per carat globally.

Commercial production commenced in January 2015 through the alluvial mining company Sociedade Mineira Do Lulo (SML). Mining operations are actively carried out along a 50-kilometre stretch of the Cacuilo River, utilising heavy excavators, haul trucks, and a 1.1 million tonne per annum processing plant. This facility features advanced XRT diamond recovery technology, capable of recovering exceptional large diamonds up to 1,100 carats.

How We Operate

Alluvial Mining Process

01
⛏

Excavation

Excavators and haul trucks mine surface deposits of gravel, sand, and clay along the floodplains (leziria) and terrace deposits of the Cacuilo River. The leziria areas are accessible during summer months when rainfall conditions allow.

02
⚙️

Processing

Mined material is processed through a 1.1 million tonne per annum facility equipped with XRT (X-Ray Transmission) diamond recovery technology, capable of recovering individual diamonds up to 1,100 carats.

03
💎

Recovery & Sale

Lulo commands the highest price per carat for alluvial diamonds in the world, producing an exceptional proportion of special-sized stones (over 10.8 carats) and fancy coloured diamonds in hues of pink and yellow.

Lulo Kimberlite Exploration
Project Two

Lulo Kimberlite
Exploration

The Lulo Kimberlite Exploration program is one of the diamond industry's most prospective. Exploration has been active in Angola for more than 15 years, with the primary sources for the large, high-value alluvial diamonds mined at Lulo yet to be fully discovered.

More than 560 geophysical anomalies have been identified across the concession, most of which have proven to be kimberlite when drilled. In 2022, a Kimberlite Bulk Sampling Plant was commissioned at Lulo to expedite the sampling programme.

Nineteen of the kimberlites sampled to date have proven to be diamondiferous, most notably kimberlite L164.
