KIMBERLEY – A De Beers Group major geotechnical stabilisation and infrastructure upgrade programme at the iconic Big Hole precinct is under way to ensure the long-term safety and preservation of this world-famous landmark.

The project has commenced after extensive geotechnical studies and advanced modelling identified

specific areas requiring long-term strengthening.

Work currently under way involves large-scale earthworks, excavation, and specialised engineering interventions designed to improve the stability of the terrain and protect the surrounding public infrastructure.

The primary objective of this significant investment is to safeguard local residents, visitors, and businesses whilst ensuring the Big Hole remains a protected national heritage site.

De Beers spokesperson Lesedi Ntuli noted that whilst the immediate focus was on engineering solutions and safety, the project also opened doors for future sustainable development through community partnerships.

The Big Hole holds immense historical significance as one of the largest hand-dug excavations in the world. Its history dates back 150 years to when thousands of prospectors arrived with only picks and shovels, eventually creating a massive cavity that reached a depth of 240 m. The mine was active from 1871 to 1914 and has since evolved into Kimberley’s most visited tourist attraction, featuring a museum and a preserved “Old Town” that recreates the diamond rush era.

Construction for this multi-year programme officially commenced in 2026.

According to De Beers, all preparatory work and site establishment have been completed, and earthworks are currently advancing as scheduled. The project is being implemented in sequential phases, with overall completion anticipated during 2028 or 2029, depending on weather conditions and regulatory processes.

Whilst the work is ongoing, safety remains the top priority. Certain areas of the Big Hole precinct will remain restricted to the public. Residents and tourists may also encounter temporary impacts on traffic movement and access routes, which De Beers is managing in coordination with the Sol Plaatje Municipality.

The long-term outcome of the project is expected to be more resilient infrastructure and the continued preservation of a site that defines the heritage of the Northern Cape.

As the official website describes it, the Big Hole remains a “lasting legacy for the people of Kimberley”.
