Out of 18 samples, 11 have higher gold values in the slag = Metallurgical concern.

Listen to the language being used:

"The results from the two fusions, summarised in table 1 display a high degree of variability which BBX believes to be a function of both the smelt conditions, including furnace temperature and smelt duration and the subsequent precious metal recovery process rather than grade variations within the drill holes"

"In a number of cases higher gold were extracted from the resmelt than from the original smelt, further reflecting the susceptibility of the process to subtle variations in test conditions"

Is BBX any closer to solving the metallurgical riddle than they were 9 months or so ago? Doesn't appear so imo. If anything, it appears the more data they release, the more inconsistent it becomes.
