A good ETF is SILJ - ETFMB Prime Junior Silver Miners. That ETF holds stock in AG and bunch of other silver miners, including Hecla, Fortuna, Endeavor, and Silvercorp. Some of its holdings (such as Capstone) also produce copper, because copper and silver are often located together in the same ore. So, that ETF also gets you some exposure to copper, which is at the lowest price it has been since November 2020. I bought some more shares of SILJ today.
