I am still holding my shares. Years ago I researched closed mines in the area. There were multiple mines in the area that had been producing mines, profitable mines, and only closed after they ran out of ore, and that was at prices lower than today, although I didn't account for inflation. But still, there were producing mines, tungsten, gold, even mercury.
I have no idea what could be going on behind the scenes with our stock. Maybe nothing, but possibly something.
