An open pit mine, it is in Botswanas Boteti sub district, 190km west of Francistown, and has produced more than 31 million carats. Treatment of tailings began in 2017 at the P2.1 billion Letlhakane Mine Tailings Plant, which will extend the life of the mine by 20 years.
The Letlhakane Uranium Project is one of the worlds largest undeveloped Uranium Deposits.
At Letlhakane, three different distinct episodes of intrusion are currently recognised in the D/K1 kimberlite, resulting in the formation of two ore types. LM2 has a basalt content ranging from 5% to 80% while LM1, found in the northern half of the pipe, has less than 10% basalt. There are four pipes at Damtshaa.
Letlhakane Mine is situated 50 km from Debswana39;s Orapa operation and 190 km West of Francistown, in Central Botswana. The mine was first discovered during the sampling and evaluation process at Orapa.
Letlhakane Mine is 50km from Orapa. While Letlhakane39;s open pit operations ceased as planned in 2017, its plant now processes tailings and has a capacity of up to 800,000 carats a year. Damtshaa Mine is 20km east of the Orapa Kimberlite pipe and officially opened in October 2003.
Conventional open pit method of mining will be applied at for the Letlhakane uranium project. The processing plant will employ acid heap leaching process to treat nine million tons of ore a year to produce uranium concentrate. A combination of solvent extraction and ion exchange circuit will be employed to recover uranium.
The Letlhakane mine has no processing facilities. Therefore, the diamond ore produced at Letlhakane is processed at a processing plant at its sister mine, Orapa diamond mine, about 50 km away. The tonnes mined from A/K1 pit feed two processing plants, Orapa 1 and Orapa 2.
Letlhakane Mine tailings resource treatment project is expected to extend mine life by 24 years. The operational readiness manager, Mr Kevin Mokotedi, said during a media site visit in Orapa and Letlhakane on June 2 stating that funds for project implementation were approved in November 2014.
