No surprise, why would there be anybody there except for security? There is no evidence they have done much out there since they couldn't extract any gold from 1,300 tons of gravel.
Except for the last investor's tour and a day of backhoe work.
I would be curious as to what equipment was on site. Some of it was likely leased (frontloader, dozer(2), back hoe(2), maybe pump). They would not keep this around if they were paying rent on it. Any of that stuff still on site?
