Debswana, De Beers mining joint venture in Botswana, is close to completing a tailings project that will extend the Letlhakane mine’s lifespan by 25 years.
The Letlhakane Mine Tailings Resource Treatment Project will enable Debswana to continue producing rough diamonds at the site even when mining at the main deposit comes to an end next year, Debswana said.
The project, which started in 2015, is 80 percent complete, with structural and electrical installations on course. Debswana expects it to be commissioned in the third quarter of 2017.
Production from the Letlhakane mine increased 6 percent to 460,000 carats in the first nine months of this year even after De Beers had initially planned to reduce output because of weaker rough market conditions.
