The Pearce Mineralized Area, Dragoon Mountains, Arizona

Arizona is well-known for its copper-gold porphyries and massive base metal-gold sulfide deposits such that primary gold deposits in the state are often overshadowed.
It would seem that we are often indeed destined to repeat history. In terms of gold discovery, even with all the advancements that have been made over the years, it seems we are once again on the cusp of returning to the 1800s world of gold mining. Even as you read this, a new gold rush is taking place in a sleepy little town in South Carolina.
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
The historical AJ mine, located east of Juneau, Alaska, was considered the largest gold mine in the state at one time. Joe Juneau and Richard Harris struck gold there in 1880, and it has been more recently known as a tourist destination.
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
