Jwaneng
Where a small stone is found (in Setswana)
 
The Jwaneng pipe was discovered in the Naledi River Valley ('Valley of the Stars'), Southern Botswana, in 1972.
 
Prince of Mines
 
Jwaneng Mine is the richest diamond mine in the world by value. The mine became fully operational in August 1982, when it was officially opened by the then President of Botswana, His Excellency Sir Ketumile Masire. Construction of the mine and the township commenced rapidly, the former coming into full production in July 1982.
 
Jwaneng Mine 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.
 
 
Jwaneng Mine The Jwaneng mine Aquarium plant is the first of its kind in the diamond mining industry. It has the completely automated recovery plant (CARP) and the fully integrated sort house (FISH).
 
 
Production
 
Currently Jwaneng is mining to a depth of 350 metres and is expected to reach 624 metres by 2017.

The resource consists of three separate volcanic pipes/vents namely north, south and centre pipes (two additional small kimberlite bodies have also been intersected within the pit) which erupted through Transvaal strata and the overlying Karoo sediments ~245 million years ago. 
 
Production normally varies according to mining plans of approximately 12.5 to 15 million carats per year.  In 2010, Jwaneng produced 11.5 million saleable carats.  This excellent rate of recovery, combined with the very high quality of the diamonds, continues to make Jwaneng Mine the richest diamond mine in the world, by value.
 
Safety and Conservation

Since 1984, the Mine has achieved one of the lowest disabling injury incident rates in Botswana. This year, the Mine underwent an external OHSAS/ISO audit and the Auditors recommended re-certification.
 
Within the boundaries of the Jwaneng mining lease area, there is the Jwana Game Park, which measures 17 000 hectares and accommodates approximately 1 700 animals. The park also hosts a field unit of Cheetah Conservation Botswana and also houses both white rhinos.
