Surface Indications Of Quartz Adularia Epithermal Deposits

I am going to keep to the basics of surface indications and visual clues in the rocks and minerals themselves that help me find gold-bearing veins in this classification of deposits.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Rare Silver Nuggets And Their Origins

The Tombstone Silver-Lead District, Arizona
In 1877, a prospector named Ed Schieffelin discovered silver in “the middle of nowhere” and staked two claims: “Tumbstone” and “Graveyard.” Soon a town and mining district were organized and acquired the name “Tombstone” after making a spelling correction.
Unique Rare Earth Mine in Texas
Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.
Conrey Dredge No. 4
The large buckets were favorable for the type of ground worked. The gravel was tenacious and compact, due to the existence of irregular pockets of clay.
All the Gold Ever Mined...
If you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”
