The Paragenesis of Gold & Silver Deposits
March 2015 by Chris Ralph
…if you are game for digging in and learning more about the intricate details of how gold deposits form, then let’s jump right in.
Northwestern Alaska Mineral Resources
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
Mass Wasting & Gold Deposits
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
Exploring and Mining for Uranium
For a time uranium was more popular with prospectors than gold, but this is no longer true, and it has been decades since it was common to see individuals armed with Geiger counters out in the field.
Alluvial Paystreaks
The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial paystreaks that are formed on gravel bars; the lowest level of the gold-bearing gravel is normally the richest.
Prospecting for Copper Ores—Part II
Copper is a critically important metal that we need to run our modern electronic society, and the long term outlook for this metal is for a steady increase in price.
Using Vegetation and Soil Conditions as Prospecting Aids
Wouldn’t it be great if you could know if there is gold in the ground without setting foot on the ground? Well you can, to a certain extent, if you can recognize mined ground from unmined.
Enrichment of Mineral Deposits by Weathering—Part II
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.
