Gold mining has come a long way from 100 years ago crawling around in rivers and caves
Just on BBX... when you visualise a ton of gabbro sitting in front of you being the size of a standard coffee table, it's not hard to imagine profitability when you consider it would be worth about 16k coming out the other end
From a fairly uneducated POV, if this is not some kind of huge screw up/ contamination, or perhaps one or two (ridiculous high grade) grab samples mixed through, then I guess it's believable that it would be profitable at scale if you take for granted whats been stated and achieved so far with techniques described
