Speaking from bitter experience, these kinds of miners ride off into the sunset well before many realize they have. The money disappears like breaking wind into the wind. All we can do is look at their PRs and hype with a HIGH DEGREE OF SKEPTICISM. These outfits can make wild claims to stir up high hopes. Those dreams rarely ever come close to any fruition.
I have followed penny miners for a long time. I even started a penny miner board a few years back so people can help sort out legit ones from scams. Trouble is, most of them were scams to one degree or another! There are a few good ones, but even those were riddled with problems....otherwise they would not be at pennies. If they were really good and legit, they wouldn't be public--if BONZ really had a river of gold, it would be a private company with that wealth benefitting a few people--not a good many.
The most recent and last placer operation was a failure--and the end of the pipe dream. The company predicated themselves on scooping up and processing the easy gold. Lode gold is a different animal...complex and expensive. Besides, they have no proof they have such gold other than a speck of gold in bit of quartz...
