Spider Resources, Noront Resources, Spider Resources, and Freewest Resources are three of the ROF companies at the 2009 Prospectors and Developers Association of Canada (PDAC) International Convention in Toronto (Mar. 1-4).
I have placed up on the Ring of Fire Blog a map of Level 800 at the Toronto Convention Centre, which shows the ROF companies (that I'm aware of) that have booths. I have also included the booths for Vale and Xstrata. To this point in time, Cliffs Natural Resources is not there (nor did I expect them).
If you are aware of any of the other ROF companies that will have a booth, don't hesitate to email me. I will update my files accordingly.
By the way, if you haven't attended the PDAC convention, it is well worth the visit.
