Huge Discoveries found at Abandoned Historic Silver Mines

One hundred years ago, if you wanted to mine for silver or gold, you looked for it with your eyes. Miners would pick rocks up off the ground to find the places to dig. Today, companies like Blackrock silver and Summa Silver are going back to these historic sites. Not only are there large veins very close to the historic sites, but modern technology allows much lower grades to be profitable for mining.   Blackrock Silver https://blackrocksilver.com/investors/ TSXV:BRC OTC: BKRRF   Summa Silver https://summasilver.com/investors/ TSXV:SSVR OTC:SSVRF
