BRE-X was a Canadian Company that falsely claimed a historic gold find of 60 million ounces in Canada. It's stock soared to $80 per share. As a result of the fraud, the Canadian Government demanded a strict drilling standard in its National Instrument 43-101. Honest companies world-wide have adopted the Canadian standard to prove gold reserves. DGRI uses this standard.
A few mines with 30 million ounces exist. However, no mine with 60 million ounces has yet been proven. DRGR may have it. However, it has yet to be proven. It is just speculation at this point.
Basically, all we know is that DGRI seems to have two mines with very rich potential for any penny stock.
