Survey of Energy Resources 2007
Uranium Country Notes
During the course of exploration carried out up to 1992, the Peruvian Nuclear Energy Institute (IPEN) discovered over 40 occurrences of uranium in the Department of Puno, in the south-east of the republic, but no production has taken place.
For the 2005 Red Book, Identified Resources (in situ) in the Macusani area in northern Puno were reported to amount to 3 650 tonnes, of which 1 790 were classified as RAR and 1 860 as IR: 68% of each category was estimated to be recoverable. Undiscovered resources (in situ) consisted of 6 610 tonnes in the PR category (recoverable at less than US$ 80/kgU), plus 19 740 tonnes of SR (recoverable at less than US$ 130/kgU).
