Mineral Deposit Trends: Real and Imaginary
December 2012 by Chris Ralph
One of the most important things prospectors do is work to figure out where to go prospecting. Along with understanding the basic geology and putting yourself in a favorable area, one of the things a prospector might consider in finding a location to search is the existence of mining belts also known as mineral deposit trends.Kennecott Copper Mine, Kennecott, Alaska

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.
Prospecting for Nickel Deposits
The periodic exploration efforts for nickel during periods of high prices have been sporadic and incomplete. There is a role for the prospector and geologist in searching laterites potentially rich in nickel and mafic igneous bodies that may be rich in nickel.
