E.Charters would know better then I. I know they are now mining gold at levels I couldnt even assay for when I started in the buisness. I'll ask charters and see what he comes up.

Lowest grades have to go to heap leach gold in Arizona. .015 ounces
per ton is profitably mined. Better to have .02 to be sure. Int. Canalaska has a
sucessful feasibiliity in Idaho at .022 ounces per short ton.

Hard rock "narrow vein" runs profitably in Timmins at .09 ounces to .12 ounces per
short ton. If you want to get away with any sort of mining underground, a weigh in a
.30 or better assures some light.

It all depends on your rock, your metallurgy/leachability, your tons per day, width and
other cost factors.
