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. "Lightning has now struck twice. Now I owe him two!"
