Windfall did cost 15 million and that's in an area where road access was in place and close to other mines. ROF is different kettle of fish.
While I'll agree to Noront's experiance in exploration they have no experiance in mining.
It is always worthwhile to consider 'options' and 'opportunities' but keep your feet on the ground and consider what is possible given one's capacity both financial and in personnel. Other than giving the majors something to 'chuckle' about or 'blow smoke' talk about going it alone is just hot air.
Sorry I remain optomistic enough value in insitu metals will be identified to have a major buy them and that's really what Noront is trying their best to do.
