History & Geology
Kennecott Copper Mine, Kennecott, Alaska
October 2017 by Jack Geck
For approximately 30 years, the mines produced good ore, some so rich it was simply sent straight to bagging, bypassing milling and loaded directly on the rail cars.
Researching Mineralized Areas
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.
All About Lead Minerals, Silver and Gold
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
Critical Minerals: Gold
A few quick calculations show that approximately 11 tons of gold are lost each year just in the manufacture of new cell phones.
All the Gold Ever Mined...
If you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”
Nevada's Lithium Boom
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
Bedrock Gold: When It’s There and When It Isn’t
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
Enrichment of Mineral Deposits by Weathering—Part I
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.
