World Distribution of Uranium Deposits (UDEPO) withUranium Deposit Classification
Background
In 1996, the IAEA published the Guidebook to Accompany IAEA Map: World distribution of Uranium Deposits (the ‘Guidebook’). This publication, which was the culmination of a process that began in 1990, introduced a descriptive deposit classification that expanded upon the classification used in the OECD/NEA-IAEA Red Book. Experts from six countries and from the IAEA collaborated on establishing the deposit classification. They also contributed information on a total of 582 deposits worldwide, and provided summary information on these deposits that became part of the Guidebook including their location, status (operating,dormant, depleted, etc.), resources (within a specific resource range — e.g. 1 500 to 5 000 tU), average grade (within a grade range — e.g. 0.03–0.10% U), geologic age, host rocks and tectonic setting.
Provision is also made in the database to record references relating to the deposits and to include maps and photos of deposits. To have been included in the database, a deposit must have minimum resources of >500 t U at an average of 0.03% U or greater (note: exceptions to these guidelines have been allowed in a small number of cases where small deposits occur near operating or proposed production centres).
