Enrichment of Mineral Deposits by Weathering—Part II
April 2016 by Chris Ralph
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
Critical Metals: Copper
From time to time I’ve been doing a series on critical metals and how important they are to our complex and technological society. This month we are going to take a look at copper, and how important that metal is to our modern lives.
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.
Ganes Creek After The Flood
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
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.
Perception of Mining vs. Reality
Many modern mining companies have taken to making a special effort to ensure the goods and services they need are supplied as much as possible out of the local economy.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.
All About Quartz—Part I
One of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
