History & Geology
Alaska: Kodiak Islands Mineral Resources
March 2016 by Jim Halloran
The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.
Gold in The Silver Crown District, Wyoming
When my field assistant Jay Roberts and I entered the mine, it appeared as if someone just walked out of the mine, turned off the lights and never returned.
Placer Gold Deposits of Utah
The placer deposits of Utah occur in two distinct types of environments. These are 1) placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2) placers found in major rivers and derived from unknown, distant sources.
Mineralized Faults and Contacts in the Search for Gold
Fault zones and rock contacts are important because the vast majority of gold and silver deposits, as well as those of many other metals, are formed by hot, mineralized water solutions.Mineral Deposit Trends: Real and Imaginary
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.
Liberty and the Phoenix Mine
Liberty, Washington is located in the mountains near Yakima and Ellensburg. There is nothing much in Liberty except for about 20 houses on patented mining claims and a lot of dry holes.
Exploring A Historic Lode Mine
Climbing up the debris, I pointed my flashlight up a shaft ascending straight up as far as my light would shine. It was the stope of the pay shoot leading to the old tunnel above!
The Wisdom of Mark Twain—And Tales of Cheating the Unwary Prospector
I (enjoy) Twain’s description of a gold mine, “A hole in the ground with a liar at the top.” Some humor here? You bet, but I’m sure he meant it to be a real eye opener as well.
