Placer Gold vs. Lode Gold and how to find it!

Placer gold mining is much easier. The gold is already separated from the rock, and gravity has concentrated the gold into creeks and rivers where it is more easily accessible. All the prospector needs is some simple tools, a gold pan and maybe a sluice box and they are ready to start mining. Lode gold takes a lot more equipment and generally a

The true cost of producing an ounce of goldProvident

May 23, 2017Much of the gold found on earth was mined and prospected many years ago. The process of finding and mining new sources of gold is a challenging endeavor. Our mining techniques have grown more sophisticated in modern times, but we can still only mine what is available. And the more scarce gold becomes, the more likely we are to see prices increase.
