Not just Gold and Silver have this pattern, but also most miners. DCFM

Brian Lundin:

"There's also a very powerful technical picture developing. Both gold and silver are tracing out a cup-and-handle formation similar to the ones they formed during the 2008 credit crisis and the subsequent recovery from that crisis. After that, the metals rocketed higher out of those cup-and-handle bottoming formations. I fully expect a similar performance this time around, which would be a pretty exceptionally profitable situation for gold bulls."
