What does Warren Buffett say about precious metals?

I'm curious to know what renowned investor Warren Buffett thinks about precious metals like gold and silver. Does he see them as a SAFE haven for investors during times of uncertainty, or does he have a more skeptical view? It would be interesting to hear his perspective on the role of precious metals in a diversified portfolio, and whether he believes they offer a solid return on investment over the long term. Given his track record of successful investments, I'm eager to understand his rationale behind any stance he may have on precious metals.
