Prospecting With The Help of Fluvial Geomorphology
March 2011 by Jim HalloranQuiz 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?
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
The Beatty Mining District in south-central Nevada has been one of the most productive Mining Districts in the state, producing millions of ounces of gold together with silver, fluorite, mercury and other valuable minerals.
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.
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.
It was the middle of winter and the valley was covered in snow, making prospecting a matter of sinking shafts in the ground.
…there are loads of different copper minerals, but a large number of them form first in the ground as chalcopyrite and then through the effects of weathering are changed into other minerals like malachite, cuprite and chrysocolla.
The process of recognizing ores all starts with being able to recognize some basic minerals and knowing what hard rock ore looks like in the districts where you prospect.
