Understanding and Prospecting Benches
September 2011 by Jim HalloranThe most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
The more experienced prospectors know these lesser known spots are the types of places where big finds are still made.
Ivory Coast has considerable gold reserves, and this nation has the largest area of greenstone belts prospective for gold in the continent.
Most prospectors learn early that pyrite is fool's gold...but the truth is it can be an excellent indicator mineral for gold and in many cases does contain small amounts of gold.
One of the most important things prospectors do is work to figure out where to go prospecting. Along with understanding the basic geology and putting yourself in a favorable area, one of the things a prospector might consider in finding a location to search is the existence of mining belts also known as mineral deposit trends.
