De Beers begins underground production at its world-class venetia mine in South Africa

The US$2.2 billion investment to take South Africa’s leading diamond mine underground bolsters De Beers’ global production and will benefit the South African economy and host communities until at least 2046


Surat : De Beers Group has celebrated a key milestone with the delivery of first production from underground operations at its Venetia Mine in Limpopo, South Africa. The overall construction of the underground mine is now 70 per cent complete, with construction and production ramp-up continuing over the next few years.

Venetia Mine, South Africa’s leading diamond mine, ceased open pit mining operations in December 2022 after 30 years of production from the Tier 1 asset. De Beers embarked on the US$2.2 billion underground expansion in 2012, in what represents the biggest single investment in the country’s diamond mining industry in decades. The highly mechanised underground operation will deliver up to seven million tonnes of kimberlite ore per year to produce between 4.5 million and 5.5 million carats of diamonds annually.

Moses Madondo, Managing Director of De Beers Group Managed Operations, said: “The investment in taking the world class Venetia Mine underground enhances De Beers Group’s global production for the long term and is an indication of our commitment to South Africa. Our incredible team of employees and contracting partners have pulled together fantastically to achieve this major milestone of first production from the underground operation. We look forward to seeing this high performing team continue the good work as we ramp up production over the next few years, bringing profound benefits to our workforce, our host communities, commercial partners and South Africa as a whole.”

The underground project currently employs 4,300 people, mostly from the host communities of Musina and Blouberg Municipalities. De Beers commissioned a US$10.5 million training centre in June 2021 as part of its operational readiness framework to enhance the transformation of people, processes and systems for the successful transition from open pit to underground mining. To date, a total of 180 employees have successfully transitioned to underground operations without any job losses for Venetia Mine’s permanent employees.

The underground mine, which comprises the K01 and K02 orebodies, will enable Venetia to mine to depths of up to 1,000 metres. K01, a sizeable orebody measuring 550 metres x 120 metres, will be responsible for the majority of production, generating an average of 3.5 million carats from about 4.5 million tonnes a year of material. The K02 orebody, measuring 200 metres x 300 metres, will provide the balance, producing about one million carats from 1.5 million tonnes to 2.5 million tonnes a year of material.
