Perception of Mining vs. Reality

Weathering, Erosion and Placers
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
Gold of the Iditarod Mining District, Alaska
It was the middle of winter and the valley was covered in snow, making prospecting a matter of sinking shafts in the ground.
Nevada's Silver City Gold District—Part I
The name Silver City is quite ironic as it doesn’t really fit the area’s metal production. The area encompassing the Silver City district is a great, stand-alone gold district, where the production value of gold has been much more than that of silver. Since the initial discovery of gold-bearing veins in the mid-1850s, the area has been a center of continuous small and large-scale gold production.A New Look at Old Mines
Exploration companies are actively looking for properties with profitable potential, even if the ground was once cast off as too low in grade to be economically viable. This is especially true in states that are reasonably friendly toward...
The Many Facets of Iron
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
The Potholes—California’s Oldest Known Mining District
Every time we prospected here we found gold, sometimes some really coarse flakes, but no large nuggets (yet).
Gold, Quartz & Chalcedony—Part II
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.
