Researching Mineralized Areas
December 2015 by Chris Ralph
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.Using Favorable Rock Types to Find More Gold
The more experienced prospectors know these lesser known spots are the types of places where big finds are still made.

Gold specimens that include visible crystal formations are among the rarest, most attractive and most valuable forms of gold to be found.
The Coolgardie Gold Mining Camp of Southern California
The area was mined intermittently from around 1900 to 1915, but was also mined in the late 1800s, with a total output valued at about $100,000, which is around $9.5 million at the current gold price.
The Amazing Mineral Tourmaline
It is a gemstone, and yet it is also closely associated with many types of metal ores. It's valuable itself but often points toward other valuable minerals—that is certainly something prospectors want to know more about!
