You are totally right zehn.  The above comments that 0.5% cobalt grades are "medium" or "OK" are, at best, somewhat ignorant or, at worst, deliberately misleading.  

31 metres @ 0.52% cobalt from 33 metres depth is, by any measure, a fantastic intersection.

A low cobalt grade is less than 0.05% Co.  Typical medium grades (in Aus) are 0.05% to 0.1%. Good grades (also in Aus) are, say, 0.1% to 0.3%.  Anything above 0.3% is considered high-grade and 0.5% to 1.0% is very high to exceptional!
