Using Structural Clues to Locate Buried Placer Channels
April 2014 by Jim HalloranThey must have assumed the paystreak was spotty and had been mined out, so they never mined as close to the side of the valley as they should have.
A retired gold prospector spent hours digging up his fortune in the northern goldfields near Kambalda, Western Australia, after finding the target with his metal detector.
There are several counties around Shasta County that offer very good gold detecting. Many of these locations are old hydraulic pits. While detecting these old pits over the years I have come up with some ideas on how to go about hunting them.
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.
If you are interested in researching mining claims for any purpose, you will first have to decipher the BLM’s LR2000, a Rube Goldberg database seemingly designed by a 1980s Soviet-era computer hacker.
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Because the forces of erosion and gravity tend to carry lighter materials like quartz away more easily, the heavy minerals like gold or silver will tend to be concentrated in the general area around the vein outcrop. These concentrations are what make residual placers so attractive.
