For instance, Hecla Mining (NYSE:HL) only brought its San Sebastian mine into commercial production last year. While it did produce nearly 4.3 million ounces of silver last year, it’s also a gold-producing mine. Similarly, Casa Berardi is a big producer of the yellow metal for Hecla, and there are numerous expansion opportunities still to come with this mine. Hecla’s gold, silver, and base metal production is about as balanced as it gets from a revenue perspective.
This ongoing and dynamic shift in production demonstrates that gold and silver miners are far more nimble than they’ve ever been. They’re also arguably looking further into the future than they’ve ever done before. Rather than relying solely on current spot prices to drive their decisions, many are taking a diversified and/or hedged approach that lets them take advantage of gold during times of uncertainty, and silver during periods of economic expansion. (Silver has more practical uses than gold.)
All told, these shifts have this Fool believing that gold and silver mining companies are looking stronger than ever.”
