15-16 year old data very early in the exploration program (written in the pre-feas to describe the history of the bench) does not take precedence over current WB data indicating almost 90% assays are below the 5000 ppm arsenic cut-off.
Bottom line is where we are today: Very high purity antimony (low arsenic and other contaminant metals) at very high concenterations.
By the way, even in '93-'94, only one of the holes was >1% arsenic (and only 25 ppm antimony, a worthless hoe indeed), the other two were below 5000 ppm (yet still worthless holes for Sb)!
I'm afraid I do not understand your concern on antimony purity at WB, it is wonderfu low arsenic antimony.
