Geology is a science of general tendencies with frequent exceptions, not one of hard and fast rules that are always true and never vary. For almost every well-accepted rule of gold deposits, I can point you to a number of important exceptions.

Silver nuggets have been described as “ultra-rare,” “prized” and “unique.” Naturally occurring silver nuggets are rare enough to suggest caution when purchasing. Fakes have reportedly been produced and misrepresented for sale as genuine specimens.

There are times when being able to recognize a type of rock can make you a much more successful prospector.

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