History & Geology
Liberty and the Phoenix Mine
June 2013 by C.A. "Charlie" Cook
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.Why Haven't They Mined This Claim?
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Mining Pegmatite Deposits
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
Epithermal Gold and Silver Deposits
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
The Gold, Silver and Base Metal Mines of Eureka, Nevada
...the area around Eureka, Nevada is well mineralized and seems to have a bright potential for future production of all sorts of metals.
The Ups and Downs of Geologic Faults
Faults are fractures, breaks and broken zones in the Earth’s crust where one side of the break has moved relative to the other, and they come in many different varieties.
The Seven Troughs Mining District
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.
Rock and Formations of the Mother Lode Gold Belt
The faulting, folding and shearing that occurred in the Mother Lode belt has created zones of structurally weak rocks or contacts between different types of rock, which has been favorable for the deposition of gold bearing ores.
