GOLD RUSH: Gold and Gossan

Gold Prospectors like to generalize gold deposits into two groups lode gold (gold which is found in place in outcrop) and placer gold (detrital gold eroded from a nearby lode and deposited in a stream). Both deposits are important, but for the gold prospector, placer gold deposits are most important because many can be worked with smaller resources and less cost that most lode gold deposits.
