In this article, we’re going to take a look at the minerals that contain gold and silver, and how you as a prospector can identify them in the field.
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
There are many prospects within the known mineralized area and along the margins of the mineralized area that should be examined for gold and silver.
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.
…to see the huge differences between the gold production amounts of the Western States, let’s look at the gold production—both hard rock and placer—of these 13 states up to the present.
