I imagine many have got bored and left the party. It's a good business model for a life style company. Buy some spent land. Drill it and repeat. All requiring cash of course. Nice work if you can get it.
I think THR have too many irons in the fire. To be successful they need to concentrate on a single resource. Drill it properly to get enough detail about the deposit then mine it or sell it. At the moment they seem to flit from resource to resource. It seems they're stringing the market along. Just doing enough.
You're assuming demand, I'm assuming little demand. The volume has been pretty low for a while. Is this because every one knows there's a large seller. Or THR have never produced anything, so far.
