Geological & General Job Sites
A really good site with jobs listed by general category. Includes both industry and academic listings.
Geological Society of America
This site sometimes has a few listings not seen elsewhere. Dominated by academic positions. But underneath the academic positions there is a listing of opportunities for students.
A site better than Monster.com, with a better layout and a specific mining category to search in.
The mother of all career sites, but again relatively few geology jobs. Enough, though, to make it worth your while to post your resume on this site.
