Buffett isn't entirely adverse to metals such as gold, the reason he doesn't buy gold is he doesn't think it's often undervalued.

"Warren Buffett made an unusual move in 1997 when he bought 111 million ounces, or nearly 3,500 tons, of silver. The famed investor's purchase helped make Thomas Kaplan a billionaire."
