Not too many gold/silver miners have been left behind by this point, but MUX might be one of the better known options still kind of lagging. Seems like they had something that roiled things a while back, but still a good company. That said, I haven't researched it for a while.
Nevada Copper NEDVF has the best looking chart of all the index below. Getting ready to RE-start commercial copper production, and they have a decent precious metals component that could represent an increasingly important percentage of the revenue stream.

Sorry the index is so small, I had to shrink it down to make it all fit.
