I skimmed through the financial that talked about the work done on the claim, but it does seem to be a valid claim (or claims), and they say they are obtaining permits through the BLM which are easily verifiable. As for the sampling results, etc. the numbers seem pretty damn good for a placer, which are one of the toughest kinds of deposits to properly assess through sampling. Sampling of a placer is so easy to bias, or misinterpret. Or salt.
I'll have to go back through the discussion in detail, and see if they have any other info on a website, maybe? I am skeptical of course, anytime a Vancouver-based geologist is involved in an Arizona placer project. And simply skeptical of any Arizona placer project for that matter. Hobbyists can have a fun time with them, but I don't know of any commercial Arizona placers that have been profitable in recent decades.
