Venetia is South Africa’s leading diamond mine. Open pit mining was completed, as scheduled, in 2022 and first production from the underground operation was delivered in June 2023. Venetia is processing lower grade surface stockpiles while the operation transitions to underground. This will continue as the underground production slowly ramps up following the first production blast in mid2023. It is expected to ramp up to steadystate levels of c.4 million carats per annum (Mctpa) production over the next few years.
De Beers has devised an autonomous mining roadmap for its Venetia Underground Mine (VUG) that will – once fully implemented – result in the new $2 billion mine becoming one of the most mechanised and automated mining operations in the world. |

Anglo American owns 85% of De Beers Group, the world's leading diamond company. The remaining 15% is owned by the Government of the Republic of Botswana (GRB). De Beers Group and its partners produce around one third of the world's rough diamonds, by value.
De Beers’ legal ownership of De Beers Consolidated Mines (DBCM) and its subsidiaries is 74%. For accounting purposes De Beers consolidates 100% of DBCM as it is deemed to control the BEE entity, Ponahalo, which holds the remaining 26%. The Group’s effective interest in DBCM is 85%.

Summary:
The Venetia kimberlite cluster was emplaced into the 2 Ga high grade metamorphic Central Zone of the Limpopo Mobile belt. This belt consists of three tectonic units: Southern Marginal Zone, Central Zone and Northern Marginal Zone, intruded by Proterozoic dolerite dykes and sills. The kimberlite cluster consists of 13 pipes and one external dyke. The current Diamond Resource is represented by four of these pipes, i.e. K01, K02, K03 and K04, totalling 27.3 ha at the current land surface. The remaining kimberlites are all less than 1.0 ha in size, with the majority being less than 0.2 ha in size.
The regional structure within the Central Zone played a significant role in controlling the emplacement of the kimberlites and resulted in a prominent west-north west orientation of the pipe shapes. The kimberlite bodies are characterised by steep-sided and irregular shapes as a result of the fault, joint and fracture orientations. They consist of several texturally distinct phases of kimberlite, varying from several types of volcaniclastic kimberlite lapilli tuffs to several coherent kimberlite types. All three of the main kimberlites (K01, K02 and K03) are monogenetic pipe complexes characterised by multiple kimberlite emplacement events.
Summary:
Venetia is South Africa’s leading diamond mine. Open pit mining was completed, as scheduled, in 2022 and first production from the underground operation was delivered in June 2023. Venetia is processing lower grade surface stockpiles while the operation transitions to underground. This will continue as the underground production slowly ramps up following the first production blast in mid-2023. It is expected to ramp up to steadystate levels of c.4 million carats per annum (Mctpa) production over the next few years.
The cave mining method allows underground mines to achieve the same type of production rates that are normally associated with open pit mines and this is the case at Venetia. Once in full production, the VUP will produce approximately 6 Mt/y ROM to deliver between 4.5 and 5.5 million carats of diamonds a year.
The Venetia Underground Project will extend production at Venetia to at least 2046, and will allow the company to fully access both the K01 and K02 kimberlites at depth.
K02 is more uniform in nature and will produce some 4 Mt/y while for K01 has more intrusions and therefore more waste; it will produce about 1.9 Mt/y. The mining method will be a specially modified version of sub-level caving. The mine will use two 1,070 m shafts – production and service, each concrete lined and 7 m in diameter. A twin decline has also been successfully developed and has been utilised to tram waste material from the underground workings to th ........
