There's an older plugin for iPhoto called
Metadata Export for iPhoto. I've not used it but it might export the metadata of the files you're interested in to a text file that you can cut and past from.
The screenshot on the site doesn't show places but it probably was taken before iPhoto 09. If you give it a try I'd make a backup of the iPhoto application before applying it.
UPDATE: it will install on iPhoto 09 and export Archival Date, Comments, Creation Date, Format, Height, Keywords, Modification Date, Path, Rating, Rotation, Title and Width to a csv, txt or plist formatted file.
