Probably not. They are selling old previously mined gold and quartz, but unlikely they are currently mining as they make no claims that they are. They are seriously delinquent with their required SEC filings, and they have not turned a profit in years, if ever.
The mine is so unprofitable they decided to open themselves as a tourist attraction instead. The State had some problems with that.......
The company has also been more focused on selling stock than gold.
It certainly does not help the case that Ruby, and NBRI, will ever achieve riches. Especially because Sixteen to One is an underground hard rock mine. Not a placer like Ruby.
