Having our own lab and staff is also important from the point of view in maintaining confidentiality of the process.The process for extraction and analysis go hand in hand.This may raise red flags for some,but if you were running a scam,there would be no way you'd want to raise red flags.BTW it would be technically impossible to "salt" the BBX ore.
The company doesn't have to announce anything confidential that would be to its detriment,so when it announces that it has a consistent process there will be a hue and cry saying that its not verified.Let them.Smart move to get a top man with credibility.
We may wonder why keep the process proprietorial?There are 2 main reasons
-there may be other orebodies held by other cos. where a jv could be done
-reduces soveriegne risk -the co's knowledge is needed to extract the ore
So although it is inviting downramper material, the company has the main game in mindroducing gold bars- and these are getting closer.
