What is Placer Gold and How do You Find it ...

12/09/2018  Placer gold is a term that refers to gold found in a secondary deposit. Usually gold occurs in lode deposits. However, the weathering of the hard rock and action of rivers and even glaciers in some places have carried the fine gold nuggets and particles and deposited them somewhere else away from the original lode deposit.

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

Placer gold accumulates over time when it erodes from hard rock veins. Gold dust doesn’t form in the river, it is transported there and forms concentrations. The origin of that gold is usually from a vein up on the mountain. Creation of a Placer Gold Deposit Here is an example. Through geologic processes millions and millions of years ago, a gold vein forms in some type of rock.
