I recently found an article that said the UN had
accounted for 330 tons of “yellow cake” in 1991.

I can’t find that story now, but would appreciate
some help. If true, then Saddam had acquired an
additional 220 tons of enriched uranium from somewhere -
after 1991 and under the noses of the IAEA.

I have so few hours to search closely these issues that I must defer to those that can follow the issues much closer. But the facility for nuclear research was not limited to only the Salman Pak facilities. There where bio/nuclear weapon labs attached to some of the air bases in al Anbar for instance.
So it is reasonable to conjure up where they may have had more then one holding area for this stuff. One thing never disclosed is to what level did they mine uranium ore from al Anbar province where Iraq had mining operations.
I had big plans a few years back into investigating just what was mined from the phosphate and other mines located east and north east of al Rutbah (some sixty miles south of the Syrian border, roughly between al Quim and the Jordanian border).
For all we know they may have been slowly obtaining uranium ore from their own country as well as seeking it elsewhere.
So your question regarding the 330 tons verse the 500 or so tons is not so easy to answer.
