Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.

Polymetallic skarn deposits are an interesting class of deposits that can contain a number of different types of metals.

…let’s dive in and take a closer look at these rich gold and silver-bearing minerals to find out what they are, where they form, and how to identify them.

This mine was a real wonder of engineering, and the water supply and drifts had to be carefully managed to keep it in operation. In fact, it didn’t close due to lack of gold, but instead closed with the fall of the Roman Empire.
