Debswana appoints new Jwaneng Mine GM

12 july 2019

debswana_logo.pngDebswana, a joint venture between De Beers and the Botswana government, has appointed Koolatotse Koolatotse as the new general manager for the Jwaneng Mine.
He rejoined Jwaneng Mine as the mining manager in 2013. 
He was then appointed senior mining manager in 2015 until his elevation to the position of assistant general manager in 2017. 
Debswana said Koolatotse has contributed immensely towards the “sterling performance” of Jwaneng Mine. 
“Over the years Koolatotse has demonstrated exceptional leadership in a number of key areas including safety, leadership development and technical expertise,” it said.
“He was instrumental in the delivery of the massive P24 billion CUT 8 project which was delivered safely, on time and on budget.”
Jwaneng Mine is the richest diamond mine in the world by value. 
It is the flagship of Debswana due to substantially higher dollar per carat obtained for its gems. 
Jwaneng Mine contributes about 60-70% of Debswana’s total revenue.
