As a fact SILVER appears 16 times more than GOLD in the Earths crust.
You say there are billions of ounces of SILVER in these waste dumps, I say BS.
Let's divide 3 billion by 16, = 188 million ounces of GOLD.
Now with a GOLD/SILVER ratio of 45 don't you think these mining companies would be more interested in extracting the GOLD from these so called waste piles?????
You have no credibility. PS Learn some basic math before you spout garbage.
