The Athabasca thegrades are very high. I live in Sudbury and have lived in Elliot Lake a town about an hour and a half drive. From the late 1950's to the early ninties there were several Uranium mines operated by Rio Algom and Denison in Elliot, Denison currently mines in the Athabasca. They were all low grades in Elliot compared to the Alberta mines. One company currently in Elliot Lake is Pele Mountain Resources GEM.V they are fully on track to producing although the market hasn't showed much confidence given their current SP. In my opinion the only faith I have in KXL's uranium prospects are the ones located in the Athabasca Basin.
Cheers KXLer's!
