I'm really not prepared at this point. We were surprised at the high indication of airborne input. It's probably not too surprising when you think of strong winds blowing across huge expanses of the sort of landscape you saw yesterday. Also, I don't know if you saw any of those monster trucks going across. Often all you see is a great big black moving dust cloud around those, so they mobilize a lot of material as well.
Of course the only period we have that for is the winter four months. What we don't know is how much of that will run off with the snowpack into the river or its tributaries during spring melt, and that's something we plan to try to do next year. We were simply unable to raise the money to do it for this year, but there's really no way right now. We're hoping that via fingerprints we can separate perhaps tailings ponds from stacks from mobilization of surface material, but I don't know how probable that is at this stage in our analysis.
