How Mesothermal/Orogenic Gold Deposits Form
August 2021 by Chris Ralph
These deposits are very widespread across the planet. In fact, they are so extensive that something around 75% of all the gold ever mined comes from these types of deposits (if one includes the placer deposits that also formed from them).
Rand, Red Mountain, Atolia Mining Districts of Kern and San Bernardino Counties, California
This area could be re-evaluated for placer scheelite and gold potential in the future along with sand and gravel processing…
The Mineral Range Districts of Utah
Most of the commercial mineral deposits are on the south and southwest part of the range between Minersville and Milford, though small amounts of gold and silver have also been found in iron-rich outcrops in the basalt to the south of Milford.

The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.What Are Those Rocks In My Pan?
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
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.
Gold Deposits of Montana
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
Why Did This Silver Mine Close? - Pt III
Narrowing down a closure date will allow you to check the commodity price during that time and possibly confirm that a low price, rather than a lack of ore, was the driving force that closed the operation.
