Rössing Uranium Ltd presently investigates the possibility of a life-of-mine extension (LoME) for the Rössing Uranium mine. During the LoME, some of the dust emission sources on the mine site may change. The tailings impoundment, various waste dumps, other rock dumps as well as the open pit will for instance change in size. The production rate and hence the tons crushed and milled will reach a climax during the life-of-mine extension. Rössing Uranium requested Necsa to perform a dose assessment to compare the current radiological impact of the mine on members of the public with the impact during the life-of-mine extension and also to compare the radiological impacts after mine closure. Details on the re-assessment as well as the results are discussed in this report.
