What I think that means goes back to what Ken stated in an email that has been posted here before...
"This was a fairly sudden trip for us. The board had discussed this issue some time back and decided that attending the PDAC this year was not a priority for us and our time and resources would better be spent on the task at hand. However, we had several recent requests to meet with mining companies if we were to attend the PDAC and for that reason only we decided to attend.
At that point we thought maybe we should exhibit at the show as well, but all floor space had been booked for nearly a year now and the Newfoundland section was only reserved for prospectors in which the government helps to offset their cost of attending. Therefore we had nowhere to set up. However, we are offered a place at the Newfoundland pavilion to meet and display our projects."
Based on that statement, it would appear to me that Kat is not listed as an exhibitor, but rather they are attending in the prospector area. To be listed as an exhibitor, such as Vale or any of the other companies that you can find listed in the virtual floor of the PDAC, you have to pay for a booth and be registered. Since KAT tried to get space too late, they are not an official exhibitor. They are in fact listed at Booth #137
