Stories are good but facts are better. Unfortunately I don't have current facts to share. I was there before construction began and stayed after it was shut down. Take a look at the original plans for the tailings dam if you want to see a show stopper. The 4km tunnel was not what stopped the project. I have heard that the new thoughts are to build a 14km tunnel so they can pull all tailings out of galore valley and avoid some very expensive road building at the same time. My guess on novas reason for selling is purely financial strategy. Pretty tough for a small company to hold on to such an asset when there is no quick plan to move ahead. I believe they still own copper canyon and haven't put up the for sale sign on that asset.
