Prospecting for Nickel Deposits
November 2010 by Chris Ralph
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.
The Pearce Mineralized Area, Dragoon Mountains, Arizona—Part II
There are many prospects within the known mineralized area and along the margins of the mineralized area that should be examined for gold and silver.
Nevada's Silver City Gold District -- Part II
May 2016...this district has had a continuous life of gold mining and milling that spans 150 plus years, and it appears that it will keep pressing on for many more years of production.
The Tombstone Silver-Lead District, Arizona
In 1877, a prospector named Ed Schieffelin discovered silver in “the middle of nowhere” and staked two claims: “Tumbstone” and “Graveyard.” Soon a town and mining district were organized and acquired the name “Tombstone” after making a spelling correction.
The Verde Copper-Gold-Silver-Zinc District, Jerome, Arizona
When I was a student in the College of Mines at the University of Utah, the Verde district was used as an exploration model for “submarine volcanogenic massive sulfide deposits.” So I looked forward to visiting this district and the town of Jerome in central Arizona in the spring of 2012.
A Journey Into the Silver Peak Range
The Gold Rush in California called hundreds of thousands of souls to leave their homes to journey to the the far reaches of the West. At first the rich goldfields of the Sierra Nevada beckoned to these adventurous pioneers.
Strategic Metals—Part I
A bill was introduced and passed by the House of Representatives earlier this year that should make the exploration and opening of a mining operation faster and easier.
The Goldfield Mining District, Nevada—Part I
An example of some of this extraordinary ore was a lot of about four tons from the Florence mine during the last days of a lease that averaged over 300 ounces of gold per ton.
