I read the Excelsior(MIN) bull board and the CRUX MIN report and the example I gave of $.31 a share for VD value is low because MIN is in trouble and isn't producing copper. Their FS is supposedly not doable as reported, lol, after all that derisking and $. MIN is still trying to figure out how to get the copper out of the ground! Imho our VD asset is equal to perhaps twice as much ($.60) of our share price. It's just a wild guess /opinion. 
In-situ leaching is complex and only works for certain soil/rock conditions. We should spend more on VD to try to de risk more in light of the MIN issues.
