History & Geology
The Goldfield Mining District -- Then and Now
March 2017 by W. Dan Hausel
In 1983, some of the ore yielded more than 2,500 ounces of gold within 30 feet of the surface. The shoot pinched to a narrow vein.
The Pedro Gold Dredge
The decision was made to move the dredge intact, a massive undertaking indeed. The goal was to move it only one mile to the Busby’s Chicken Gold Camp, but what a mile that was to be.
One Question, Forever Unanswered—Did He Really Find the Gold?
This was one of those stories where you have no doubt that the person telling it believes it to be true. But was it?
The Birimian Greenstone Belts of West Africa
A few years ago I had a tremendous opportunity to visit Australia and hunt for gold there. The geology of the gold deposits there was somewhat different from what I was used to here in the US. I learned a lot about greenstone belt gold deposits while prospecting them in person, and it was an amazing trip.
Know Your District
We have to remember that the earliest miners were not geologists, but came from a variety of backgrounds. Their survival depended on finding enough gold so they worked hard and adapted to whatever challenges these new areas presented.
Prospecting With The Help of Fluvial Geomorphology
Quiz yourself about the stream in figure 5. Based on your previous knowledge of where gold is found in a stream and in this article, where do you think you will find the most gold?
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.
Simple Rules of Gold Geology: Comparing Epithermal and Mesothermal Deposits
Geology is a science of general tendencies with frequent exceptions, not one of hard and fast rules that are always true and never vary. For almost every well-accepted rule of gold deposits, I can point you to a number of important exceptions.
