How Buffett's Silver Purchase Made A Man A Billionaire

Business Insider reports that Warren Buffett helped Thomas Kaplan become a billionaire.

Buffett bought 130 million ounces of silver in the late 1990s, just before Kaplan listed his silver-mining company.

Buffett has did Kaplan another favor when he bought a stake in Barrick Gold last quarter.

Barrick co-owns the Donlin Creek gold deposit in Alaska with NovaGold, which counts Kaplan as its chairman and largest shareholder.
