Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.

The Struggle to Reopen Alaska's Largest Gold Mine
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.
Alluvial Paystreaks
The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial paystreaks that are formed on gravel bars; the lowest level of the gold-bearing gravel is normally the richest.
Confluence Placers

Critical Minerals: Tungsten
Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds.
