Snapshot	Venetia is South Africa’s leading diamond mine. Open-pit mining concluded as planned in 2022, with the first underground production achieved in June 2023. The Venetia Underground project will continue ramping up in the coming years, extending the mine’s life until 2046. Venetia aims to implement multiple autonomous mining systems underground by 2028, though the timeline remains flexible. The newly commissioned Integrated Operations Centre (IOC) enhances productivity by providing real-time situational awareness, data analysis, and operational management. Equipped with advanced communication, tracking, and visualization tools, the IOC serves as the hub for underground operations.

• Kimberlite

Summary:

The 519 Ma 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 two of these pipes, K01 and K02. Most of the kimberlites are 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 steepsided 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. The two main kimberlites are monogenetic pipe complexes characterised by multiple kimberlite emplacement events.
