Mining certainly isn't my primary industry, although I've worked at a few different mining operations for weeks or months at a time, and dad was a geologist, so I picked up a bit of knowledge over the years. I was more into chemistry than geology when I studied at university, though I eventually went the MBA route instead.
Current Market Caps, fully diluted:
KWG: 830.9m shares x .11 = about $91.3 million.
PRB: 41.7m shares x 1.95 = about $81.3 million.
Thanks to each company for having basic and FD numbers on their websites.
I was going to look at Noront's cap too, but I have to dig into their annual report for the FD number, and it's not loading for me.
