Picks & Pans: Prospecting for Lode Gold
October 1999 by Edgar B. Heylmun, PhD
Most of the world's ore deposits have been found by prospectors, not by geologists nor mining engineers. This article has been prepared with this fact in mind.
Gondwana Gold and Diamonds
Some 250 million years ago, the Earth had just one supercontinent, known as “Pangaea.” For whatever reason, the supercontinent began to break apart. South America and Africa remained joined, as “Gondwana,” until 65 million years ago, when they split apart. The obvious “fit” of South America with Africa was noted by geologists back in the 19th century, but it was not until Alfred Wegener came out with his “continental drift” hypothesis in 1912 that people took note.
Blackberries and Gold
There were iron stains all over and even a few places where I could see iron trash sticking out of the bedrock. These would be ideal spots to start with as the gold travels with the iron and lead.
