As far as the fire assay technique is concerned apart from not knowing the exact composition of the custom flux, using a nickel collector is a common method as far as my research could take me but not often used as it isn't economical compared to the cheaper options so rarely used. I believe they have made even further developments from here but can't remember exactly off the top of my head.
If you have expertise on fire assay techniques it would be worth having a read back over everything they have released. If they can actually start producing a small amount of Au, Pt and Pd as they plan to it would add some further weight to the claims.
I am always skeptical hence my moves to protect capital, but if this is the real thing then it will go far higher. If it is an EXTREMELY elaborate scam then it certainly has a long way to run from here. Independent verification of the fire assay process would be nice to see sooner rather than later, the company has brought this expectation to the fore in recent releases.
Sentiment is still buy as I will accumulate some back if it falls much further.
