I also did a Google Earth fly over of the site. They are making considerable progress from when I looked at it a few months ago.
Also, my nephew is a crane operator in Phoenix. He has worked at the mine site several times over the past year or so, placing new equipment. He said that they seem to know exactly what they are doing. He's expensive and they don't waste time.
I am glad to now have a small position in $NHVCF and will be holding long term.
