    Some pyrites can contain 0.25 gold by weight or more. Although this is a tiny fraction of the ore the value of gold is so high that the pyrite might be a worthwhile mining target. If pyrite contains 0.25 gold and the gold price is 1500 per troy ounce then one ton of pyrite will contain about 73 troy ounces of gold worth over 109000
