With about 100$/kg and 0.1% uranium we should get about 100$ value per tonne of ore, which is at or slightly above my cut-off value for under ground mining which traditionally I placed at 50 $/tonne. Now with the higher costs of everything, the cut off may be closer to 100 $/tonne. So with 0.13% U we may be in business, but as you know the uranium prices have been falling during the last year.

In terms of gold grade, I think that 3 grams per tonne should be ok for profitable mining(80-90$/tonne of rock). So far we have found significant amounts at that grade or higher, so lets hope that the upcoming news release will give us more of that good stuff.

Open pit may be profitable as low as 20 $/tonne of rock value, but I am not sure how much of Hercules can be mined that way, probably not a lot
