A Review of this NRH Research Report really helps put Probe (PRB) and its growing deposit in perspective, answering such questions as "How rare is a 1MM oz. gold deposit?"
On Page 19, you see Probe's current ranking #136 of 489 1MM oz.+ global gold deposits. Won't take much of an increase in 43-101 resources to move significantly up the scale.
