Perception of Mining vs. Reality

The Ely Copper-Gold District of Nevada
The main ore deposits of the Ely district are associated with an east-west belt of altered and mineralized rocks measuring about one mile wide that extends 8 miles westward from Ely.
Exploring Iron Oxide Copper Gold Deposits
The excitement over IOCG deposits began with the discovery of a monster deposit at Olympic Dam in Australia in 1976. The discovery was accidental as the operator was searching for strata-bound copper deposits.
The Many Facets of Iron
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Ask The Experts
Q: Is there a correlation between fault zones and mineralization of economic metals?
Gold of the Iditarod Mining District, Alaska
It was the middle of winter and the valley was covered in snow, making prospecting a matter of sinking shafts in the ground.
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.
