Survey of Energy Resources 2007
Uranium Country Notes
Exploration for uranium came to an end in 1983: at that point, known in-situ resources totalled 2 400 tonnes recoverable at US$ 80-130/kgU, comprising
1 700 tonnes of RAR and 700 tonnes of IR: the IAEA estimates that 75% of these tonnages would be recoverable. Additional undiscovered resources (in situ) amounted to 13 000 tonnes, the bulk of which (10 000 tonnes) were speculative.
Unconventional resources contained in marine phosphates in Baja California amount to about 150 000 tU, as assessed in the early 1980s.
For a short period (1969-1971), molybdenum and by-product uranium were recovered from a variety of ores at a plant in Aldama, Chihuahua state. Uranium output totalled 49 tonnes: there are presently no plans for resuming production.
