Why I went to Mount Rushmore (Ad) A small miner just hit on gold in the hills surrounding Mount Rushmore, thanks to a breakthrough new technology. This could be one of the biggest gold finds since the 1870s, yet the stock still trades around 6 dollars. BlackRock and Vanguard have been quietly loading up on shares while most investors have missed the story. The same technology is unlocking hidden resource wealth across America, driving stocks up 227 percent, 378 percent, and even 773 percent. Watch the free video and get the stock name now

The last time I saw something like this was in 2008 when I predicted a stock market meltdown just three weeks before Lehman went under. See the five simple steps to prepare before it's too late
